Cautionary Note regarding Forward-Looking Statements
In addition to historical information, this Quarterly Report on Form 10-Q contains forward-looking statements subject to the safe harbor protection provided by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements relate to future events and involve known and unknown risks and uncertainties that may cause actual outcomes to be materially different from those indicated by any forward-looking statements. Some of the things that could cause our actual results to differ from our expectations are: the competitive environment and other trends in our industry; changes in our operating costs including fuel, which can be volatile; our ability to meet our cost reduction goals; our inability to achieve or maintain profitability and fluctuations in our quarterly results; our significant indebtedness; the implementation of our growth strategy; the timing of the MD-80 fleet disposal and the amounts of potential lease termination payments with lessors and sublease payments from sublessees; compliance with our financial covenants; potential downgrades of our credit ratings and the availability of financing; the concentration of our revenue from a few key markets; general economic conditions, as well as economic conditions in the geographic regions we serve; actual or threatened terrorist attacks; global instability and potential U.S. military actions or activities; insurance costs; labor disputes; our ability to attract and retain qualified personnel; an aircraft accident or incident; liability and other claims asserted against us; operational disruptions; increases in government fees and taxes; changes in laws and regulations; our reliance on automated systems; and our reliance on third-party vendors and partners. For a discussion of these and other risk factors, see Item 1A, “Risk Factors” of this Form 10-Q. All of the forward- looking statements are qualified in their entirety by reference to the risk factors discussed therein. These risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time to time. Management cannot predict such new risk factors, nor can it assess the impact, if any, of such new risk factors on our business or events described in any forward-looking statements. We disclaim any obligation to publicly update or revise any forward-looking statements after the date of this report to conform them to actual results. Over time, our actual results, performance or achievements will likely differ from the anticipated results, performance or achievements that are expressed or implied by our forward-looking statements, and such differences might be significant and materially adverse.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)
Alaska Air Group, Inc.
Note 1. Basis of Presentation and Significant Accounting Policies
Organization and Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of Alaska Air Group, Inc. (Air Group or the Company) include the accounts of the parent company, Alaska Air Group, Inc., and its principal subsidiaries, Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon), through which the Company conducts substantially all of its operations. These interim condensed consolidated financial statements are unaudited and should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. In the opinion of management, all adjustments have been made which are necessary to present fairly the Company’s financial position as of June 30, 2006, as well as the results of operations for the three and six months ended June 30, 2006 and 2005. The adjustments made were of a normal recurring nature.
The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In preparing these condensed consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities, as well as the reported amounts of revenues and expenses. Significant estimates made include assumptions used to record liabilities, expenses and revenues associated with the Company’s Mileage Plan, amounts paid to lessors upon aircraft lease terminations, the fair market value of surplus or impaired aircraft, engines and parts, assumptions used in the calculations of pension expense in the Company’s defined benefit plans, and the amounts of certain accrued liabilities. Actual results may differ from the Company’s estimates.
Reclassifications
The Company has reclassified all of its fuel hedging gains and losses from other nonoperating income (expense) to aircraft fuel, including hedging gains and losses,  for all periods presented (see Note 4). Certain other reclassifications have been made to conform the prior year’s data to the current format.
Securities Lending
From time to time, the Company lends certain marketable securities to third parties for a time period of less than one year. During the time period in which these securities are loaned to the third parties, the Company requires cash collateral for 102% of the daily market value of the loaned securities. As of June 30, 2006, the Company had $109.1 million of securities on loan under the program. These affected securities are included as marketable securities under current assets.
Note 2. Impairment of Aircraft
In March 2006, the Company’s Board approved a plan to accelerate the retirement of its MD-80 fleet (15 owned aircraft) and remove those aircraft from service by the end of 2008, which is earlier than the original retirement schedule. The Company expects to use firm orders, options and additional purchase rights under its existing order of B737-800 aircraft to replace the capacity lost from the early retirement of the MD-80s.

Table of Contents
As a result of this decision, the Company evaluated impairment as required by SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” and concluded that the carrying value of the MD-80 fleet was no longer recoverable when compared to the estimated remaining future cash flows. Accordingly, during the first quarter of 2006, the Company recorded an impairment charge totaling $131.1 million (pretax) to write down the fleet to its estimated fair market value.
The estimated fair value of the Company’s aircraft was derived using third-party appraisals and market data compiled by a third-party consultant, adjusted for certain factors deemed appropriate by management, such as the position of each aircraft in its maintenance cycle. Subsequent to the end of the second quarter, the Company received preliminary bids from third parties to purchase the aircraft. These bids did not indicate a need for further impairment as of June 30, 2006. In conjunction with the fair value determination, the Company has reassessed the useful lives and residual values of the fleet and related spare equipment and will depreciate the remaining carrying values through the estimated date that each aircraft will be retired. The estimate of residual salvage value is highly judgmental. Actual proceeds upon sale of the aircraft may differ materially from the estimate used at the time the impairment charge was recorded and the preliminary offers received to date.
The Company also leases 11 MD-80 aircraft. The current expiration dates on these leases range from January 2007 to January 2013. The Company expects to cease operation of nine of these aircraft prior to the lease expiration date through lease buy-outs, lease agreement restructuring, subleasing of the aircraft, or storing the aircraft at a long-term storage facility. At such time as one of these actions is taken on the aircraft, the Company expects to have an associated charge that will be recorded in the consolidated statements of operations. See Note 14.
Note 3. Restructuring Charges
A new four-year contract with the Association of Flight Attendants for Alaska’s approximately 2,500 flight attendants was ratified on April 26, 2006. Under this agreement, the Company paid a signing bonus, in aggregate, of $2.7 million in May 2006, which is included in wages and benefits in our statement of operations. The new agreement also included an immediate 3% pay increase, higher employee health care contributions, improvements in supervisors’ ability to work closely with flight attendants, and a number of productivity enhancements. Additionally, Alaska offered a voluntary severance package to a number of flight attendants that included, among other things, a lump-sum payment of $2,000 per year of service up to a maximum of 25 years and continuing travel benefits. During the quarter ended June 30, 2006, the Company recorded a restructuring charge of $3.8 million related to the severance amounts, which will be paid to approximately 100 flight attendants.
During the second quarter of 2005, Alaska contracted out ramp services at the Seattle-Tacoma International Airport. This event resulted in a reduction of approximately 475 employees in Seattle. Severance and related costs associated with this restructuring were originally estimated at $16.1 million, which was recorded in the second quarter of 2005.

Table of Contents
The following table displays the activity and balance of the severance and related costs components of the Company’s restructuring accrual as of and for the six months ended June 30, 2006 and 2005. The restructuring adjustment in 2005 relates to our change in estimated costs of medical coverage extended to impacted employees ($ in millions):

Accrual for Severance and Related Costs	  	2006	 	 	2005	 	
Balance at December 31, 2005 and 2004, respectively	  	$	3.1	 	 	$	38.7	 	
Restructuring charge	  	 	3.8	 	 	 	16.1	 	
Restructuring adjustment	  	 	—  	 	 	 	(2.0	)	
Cash payments	  	 	(3.1	)	 	 	(29.5	)	
 	  	 	 	 	 	 	 	 	
Balance at June 30	  	$	3.8	 	 	$	23.3	 	
 	  	 	 	 	 	 	 	 	
The Company will make the majority of the remaining cash payments during the third quarter of 2006. The accrual for severance and related costs at June 30, 2006 is included in accrued wages, vacation and payroll taxes in the consolidated balance sheets.
During March 2005, the Company notified the Port of Oakland of its decision to terminate the lease for the Oakland hangar as part of its ongoing restructuring efforts. Accordingly, the Company recorded an impairment charge of $7.7 million in the first quarter of 2005 for the leasehold improvements that will be abandoned as a result of the lease termination. Additionally, the Company recorded a charge of $0.3 million for certain costs associated with the lease termination, which have been paid.
Note 4. Fuel Hedge Contracts
The Company’s operations are inherently dependent upon the price and availability of aircraft fuel. To manage economic risks associated with fluctuations in aircraft fuel prices, the Company periodically enters into call options, collar structures, and swap agreements for crude oil, among other initiatives.
The Company records derivative instruments, all of which are currently fuel hedge contracts, on the balance sheet at their fair value. Because of historical variations in the spread between the prices of West Texas Intermediate crude oil (the commodity the Company uses to hedge) and jet fuel, the Company’s hedge contracts are not “highly correlated” to changes in prices of aircraft fuel, as defined in SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” As a result, changes in the fair value of these fuel hedge contracts are recorded each period in aircraft fuel expense.

Beginning January 1, 2006, the Company records all of its fuel hedging gains and losses in aircraft fuel, including hedging gains and losses. Prior to January 1, 2006, the majority of these fuel hedging gains and losses were recorded in  other nonoperating income (expense).  The prior period presentation has been conformed to the current year format. The following table summarizes GAAP and economic aircraft fuel expense for the three and six months ended June 30, 2006 and 2005 (in millions):

Note 5. Change in Accounting Principle
Effective January 1, 2005, the Company changed its method of accounting for major airframe and engine overhauls from the capitalize and amortize method to the  direct expense  method. Under the former method, these costs were capitalized and amortized to maintenance expense over the shorter of the life of the overhaul or the remaining lease term. Under the direct expense method, overhaul costs are expensed as incurred. Accordingly, in the first quarter of 2005, the Company wrote off the net book value of its previously capitalized airframe and engine overhauls for all aircraft in a charge totaling $144.7 million pre-tax ($90.4 million after tax).

debt arrangements range from 6.2% to 6.8%. These changes did not result in any gain or loss in the condensed consolidated statements of operations.
The Company’s $150.0 million senior convertible notes due in 2023 (Notes) became redeemable by the Company on March 21, 2006, the third anniversary of the issuance of the Notes. On March 29, 2006, the Company called for redemption all of the Notes and, in April, all of the Notes were converted by the holders into shares of the Company’s common stock. The conversion rate was approximately 38.5 shares per $1,000 of Notes at par, which equates to $26 per share. In total, this added 5.769 million common shares to the Company’s outstanding shares as of the end of April 2006. This resulted in $145.6 million of additional equity, which is net of $4.4 million of unamortized financing costs remaining from the original issuance of the Notes in 2003.

Note 10. Stock Plans
The Company adopted Statement of Financial Accounting Standards (SFAS) 123R, “Share-Based Payment: An Amendment of SFAS Nos. 123 and 95,” as of January 1, 2006. This new standard requires companies to recognize as expense the fair value of stock options and other equity-based compensation issued to employees as of the grant date. The standard applies to both stock options and restricted stock units that the Company grants to employees and the Company’s Employee Stock Purchase Plan (ESPP), which features a look-back provision and allows employees to purchase stock at a 15% discount. The Company is using the “modified prospective method,” which is explained below.
The adoption of SFAS 123R changes the accounting for stock options under the Company’s long-term incentive equity plans and changes the accounting for the Company’s ESPP. Accounting for the Company’s restricted stock awards did not change with the adoption of the standard. All stock-based compensation expense is recorded in wages and benefits in the condensed consolidated statements of operations.
Stock Options
SFAS 123R is effective for all stock options granted beginning January 1, 2006. For stock options granted prior to January 1, 2006, for which the vesting period is not complete, the “modified prospective method” for transition permitted by SFAS 123R was used. Under this method, the Company accounts for the unvested portion of these awards on a prospective basis, with expense recognized in the condensed consolidated statements of operations beginning January 1, 2006 using the grant-date fair values previously calculated for pro forma disclosures. The Company selected this method due to the relatively limited use of stock-based awards and the immaterial impact on the comparability between periods. The Company also elected to use the method available under FASB Staff Position FSP No. 123(R)-3  Transition Election Related to Accounting for the Tax Effects of Share-Based Payment Awards , which provides an alternative method for calculating historical excess tax benefits (the APIC pool) from the method described in FAS 123(R) for stock-based compensation awards. The standard also requires that tax benefits realized from stock award exercise gains in excess of stock-based compensation expense recognized for financial statement purposes be reported as cash flows from financing activities rather than as operating cash flows.
The Company’s options are typically granted with graded vesting provisions, and compensation cost is amortized over the service period using the straight-line method. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires the Company to make several assumptions. The risk-free interest rate is based on the U.S. Treasury yield curve in effect for the term nearest the expected term of the option at the time of grant. The dividend yield is zero as the Company does not pay dividends and has no plans to do so in the immediate future.

The market price volatility of the common stock is based on a combination of the historical volatility over a time period equal to the expected term of the option and management’s judgment of future volatility. The expected life of the options and the expected forfeiture rates are based on our historical experience for various homogenous employee groups.
During the three months ended March 31, 2006, the Company granted 7,675 options with a weighted average exercise price of $30.08 per share and a fair value of $14.17 per share, resulting in total grants with aggregate fair value of $0.1 million. The fair value was derived using a risk-free interest rate of 4.5%, expected volatility of 41.6% and expected life of 6 years. The Company did not grant any options during the three-month period ended June 30, 2006.
The total intrinsic value of options exercised during the three and six months ended June 30, 2006 was $6.1 million and $6.5 million, respectively. Cash received from option exercises during the three and six months ended June 30, 2006 totaled $15.6 million and $16.7 million, respectively.
There were 2,732,341 outstanding options as of June 30, 2006 with a weighted average exercise price of $31.65 per share, a contractual life of 4.7 years and an aggregate intrinsic value of $23.2 million. Of the options outstanding at June 30, 2006, 2,156,253 were exercisable with an aggregate intrinsic value of $16.8 million.

Impact of Adoption of SFAS 123R
Stock-based compensation expense recognized under SFAS 123R for the three and six months ended June 30, 2006 is as follows:

As of June 30, 2006, $4.8 million and $6.7 million of compensation cost associated with unvested stock options and restricted stock awards, respectively, attributable to future service had not yet been recognized. These amounts will be recognized as expense over a weighted-average period of 1.3 years and 1.1 years for stock options and restricted stock awards, respectively.
Had compensation cost for the Company’s stock options and employee stock purchase plan been determined in accordance with SFAS No. 123, “Accounting for Stock-Based Compensation,” net income for the three months ended June 30, 2005 would have been negatively impacted by $1.1 million, or $0.03 per diluted share, and the net loss for the six months ended June 30, 2005 would have been negatively impacted by $1.9 million, or $0.05 per diluted share.
Note 11. Earnings Per Share
SFAS No. 128, “Earnings per Share” requires that companies use income from continuing operations before extraordinary items and the cumulative effect of an accounting change as the “control number” in determining whether potential common shares are dilutive or antidilutive. As the Company reported income before the accounting change in 2005, the potential common shares from the Company’s common stock options and senior convertible notes are included in the calculation for diluted earnings (loss) per share. Therefore, for the three and six months ended June 30, 2005, the dilutive impact of common stock options and 5.769 million common shares that would have been outstanding upon conversion of the senior convertible notes were included in the calculations.
In April 2006, the senior convertible notes were converted into 5.769 million shares of common stock and are included in the calculation of the basic weighted average shares outstanding for the three and six months ended June 30, 2006. For the three months ended June 30, 2006, the dilutive effect of stock options and the effect of the senior convertible notes as if the shares had been outstanding as of the beginning of the period are included in the calculation for diluted earnings per share. Options to purchase 0.6 million

Note 13. Contingencies
In April 2006, the federal district court in Seattle dismissed a counterclaim by the International Association of Machinists (IAM) alleging that Alaska violated the Railway Labor Act status quo and engaged in bad faith bargaining. At the same time, the court also granted voluntary dismissal of Alaska’s lawsuit against the IAM seeking to compel arbitration of dispute regarding the permissibility of subcontracting of Alaska’s ramp service operation in Seattle. The appeal period has expired and these matters are closed.
However, in addition to the court cases, the IAM filed a grievance against Alaska alleging that Alaska violated the collective bargaining agreement by, among other things, subcontracting the ramp service operation in Seattle when the parties could not reach agreement on an acceptable labor contract. This matter is scheduled for arbitration in August and December of 2006.
The Company is also a party to routine commercial and employment litigation incidental to its business and with respect to which no material liability is expected.
Management believes the ultimate disposition of these matters is not likely to materially affect the Company’s financial position or results of operations. However, this belief is based on management’s current understanding of the relevant law and facts; it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of judges, juries, and arbitrators.

Note 14. Subsequent Events
In the second quarter of 2004, the Company announced its intention to accelerate the retirement of Alaska’s B737-200 fleet and remove those aircraft from service. On July 7, 2006, the Company entered into a purchase and sale agreement for six B737-200 aircraft. The Company’s seventh (and remaining) B737-200 aircraft will be donated to an aviation museum in Alaska. The six aircraft will be sold and delivered at various intervals through April 2007. The total purchase price for the six aircraft is $5.9 million, which is greater than the net book value of the aircraft as of June 30, 2006.
As part of the Company’s fleet transition plan, Alaska entered into purchase and sale agreements, subsequent to June 30, 2006, to buyout five of its nine long-term MD-80 aircraft leases. These agreements are expected to all close during the third quarter of 2006. The total purchase price for the five aircraft, including assumed debt, is approximately $80 million. As the estimated fair market value of the MD-80 aircraft is below that amount, the Company will record a charge in the third quarter of approximately $65 million. Similar to the owned MD-80 fleet, the Company will begin immediately to market these five aircraft for sale.
In July 2006, Alaska reached a new four-year agreement with the approximately 3,700 clerical, office and passenger service employees and the ramp service agents and stock clerks, all represented by the International Association of Machinists. This agreement includes, among other things, a $500 signing bonus per employee (approximately $1.9 million in the aggregate), an immediate 2% wage increase, higher employee health care contributions, fewer restrictions in Alaska’s managers’ and supervisors’ ability to work with and along side represented employees, and a provision whereby new employees will only participate in a defined contribution retirement plan. In addition, a severance package was offered to employees in the top four wage-scale steps that includes cash payments based on years of service, one year of medical coverage after the severance date, and continued travel benefits for a period of time. The amount of the charge will not be known until the number of employees accepting the severance package is known, which is expected to be in September 2006. However, for illustrative purposes only, if one quarter of the approximately 1,400 eligible employees accept the offer, the charge would be approximately $20 million.

Note A:
Pursuant to Item 10 of Regulation S-K, we are providing disclosure of the reconciliation of reported non-GAAP financial measures to their most directly comparable financial measures reported on a GAAP basis. The non-GAAP financial measures provide management the ability to measure and monitor performance both with and without the cost of aircraft fuel (including the gains and losses associated with our fuel hedging program where appropriate), aircraft impairment charges, and restructuring charges and adjustments. Because the cost and availability of aircraft fuel are subject to many economic and political factors beyond our control and we record changes in the fair value of our hedge portfolio in our income statement, it is our view that the measurement and monitoring of performance without fuel is important. In addition, we believe the disclosure of financial performance without impairment and restructuring charges is useful to investors. Finally, these non-GAAP financial measures are also more comparable to financial measures reported to the Department of Transportation by other major network airlines.
The following tables reconcile our non-GAAP financial measures to the most directly comparable GAAP financial measures for both Alaska Airlines, Inc. and Horizon Air Industries, Inc.:

ITEM 2.	Management’s Discussion and Analysis of Financial Condition and Results of Operations	
The following discussion should be read in conjunction with our condensed consolidated financial statements and the related notes contained elsewhere in this quarterly report on Form 10-Q. All statements in the following discussion that are not reports of historical information or descriptions of current accounting policy are forward-looking statements. Please consider our forward-looking statements in light of the risks referred to in this report’s introductory cautionary note.
Air Group’s filings with the Securities and Exchange Commission, including its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports are accessible free of charge at www.alaskaair.com. The information contained on our website is not a part of this quarterly report on Form 10-Q. As used in this Form 10-Q, the terms “Air Group,” “our,” “we” and “Company” refer to Alaska Air Group, Inc. and its subsidiaries, unless the context indicates otherwise.
Second Quarter in Review and Current Events
Our success this quarter was primarily driven by positive revenue trends resulting from industry-wide fare increases that began in the latter half of 2005 and continued through the second quarter of 2006. Record-high load factors and increases in passenger traffic at both carriers have also contributed to the revenue improvements over the prior year.
Our total operating costs increased year-over-year. Continued increases in fuel prices drove the majority of this increase at both Alaska and Horizon. Alaska recorded a $3.8 million restructuring charge associated with the voluntary severance package offered to our flight attendants as part of a new four-year contract. Operating expenses per available seat mile increased 2.8% at Alaska to 10.96 cents and 11.8% at Horizon to 16.93 cents compared to the second quarter of 2005. At Alaska, our unit costs excluding fuel and the restructuring charge decreased 2.1% to 7.92 cents compared to the second quarter of 2005. This decrease was primarily due to a 5.2% increase in capacity, offset by a 3% increase in operating costs (other than fuel and restructuring charges). Compared to the second quarter of 2005, Horizon had a 9.8% increase to 14.03 cents in unit costs excluding fuel. This year-over-year unit cost increase was primarily driven by higher maintenance costs and other operating expenses, offset by a 6.1% increase in capacity.
Redemption of Senior Convertible Notes
Our $150 million senior convertible notes due 2023 (the Notes) became redeemable on March 21, 2006. All of the Notes were converted in April 2006, resulting in the issuance of 5.8 million shares of common stock. This resulted in $145.6 million of additional equity, which is net of $4.4 million of unamortized financing costs remaining from the original issuance of the Notes in 2003. The conversion will result in a reduction in interest expense of approximately $11.0 million per year. See Note 8 to the condensed consolidated financial statements.

Labor Costs and Negotiations
Alaska and the Association of Flight Attendants reached an agreement on a new four-year contract for the airline’s approximately 2,500 flight attendants. The contract was ratified on April 26, 2006. The new agreement includes an immediate 3% pay increase, an aggregate signing bonus of $2.7 million, higher employee health care contributions, improvements in our supervisors’ ability to work closely with flight attendants, and a number of productivity enhancements. Additionally, Alaska offered a voluntary severance package to a number of flight attendants that includes, among other things, a lump-sum payment of $2,000 per year of service up to a maximum of 25 years and continuing travel benefits. During the quarter ended June 30, 2006, we recorded a restructuring charge of $3.8 million related to the severance amounts, which will be paid to approximately 100 flight attendants.
Subsequent to the end of the quarter, we reached a new four-year agreement with the approximately 3,700 clerical, office and passenger service employees and ramp service agents and stock clerks at Alaska, all represented by the International Association of Machinists. This agreement includes, among other things, a $500 signing bonus per employee (approximately $1.9 million in the aggregate), an immediate 2% wage increase, higher employee health care contributions, fewer restrictions in our managers’ and supervisors’ ability to work with and along side represented employees, and a provision whereby new employees will only participate in a defined contribution retirement plan. In addition, a severance package was offered to employees in the top four wage-scale steps that includes cash payments based on years of service, one year of medical coverage after the severance date, and continued travel benefits for a period of time. The amount of the charge will not be known until the number of employees accepting the severance package is known, which is expected to be in September 2006. However, for illustrative purposes only, if one quarter of the approximately 1,400 eligible employees accepts the offer, the charge would be approximately $20 million.
Mark-to-Market Fuel Hedging Gains
Beginning in the second quarter of 2004, we lost the ability to use hedge accounting because the price correlation between crude oil, the commodity we use to hedge, and West Coast jet fuel fell below required thresholds. As a result, our earnings are more volatile as we mark our entire hedge portfolio to market each period through earnings, even though the actual consumption will take place in a future period.
Historically, we have reported these gains and losses in other nonoperating income and expense. Beginning in the first quarter of 2006, however, we report these gains and losses in aircraft fuel, including hedging gains and losses, in the condensed consolidated statements of operations. Prior period amounts have been reclassified to conform to the current year format. On a consolidated basis, we had $3.8 million ($2.4 million after tax) of mark-to-market losses on our hedge portfolio in the second quarter of 2006 compared to $3.0 million ($1.9 million after tax) of gains in the second quarter of 2005. These gains and losses are reported net of the reclassification of previously recorded mark-to-market gains on settled hedges. Additionally, in the second quarters of 2006 and 2005, we recorded gains from settled fuel hedges totaling $34.4 million and $28.2 million, respectively, which are also recorded in aircraft fuel.

Table of Contents
We have provided information on mark-to-market gains or losses, as well as calculations of our economic fuel cost per gallon on pages 24 and 25. For more discussion, see Note 4 to our condensed consolidated financial statements.
We continue to believe that our fuel hedge program is an important part of our strategy to reduce our exposure to volatile fuel prices. We expect to resume our hedging activity in the third quarter of 2006, although significant changes in market condition could affect our decisions.
Outlook
For 2006, Alaska and Horizon expect capacity increases of approximately 5% and 7%, respectively, over 2005 capacity. The expected capacity increase at Alaska is due largely to the return to a full schedule after last year’s summer capacity reduction and the introduction of 12 new B737-800 aircraft in 2006, with most of the remaining deliveries in the fourth quarter. Horizon’s expected capacity increase is due to the annualization of increasing the capacity of the Q400 fleet from 70 to 74 seats, and the recently delivered CRJ700 and two Q400s. For the remainder of 2006, we expect capacity increases of approximately 6% and 5% for Alaska and approximately 5% and 6% for Horizon in the third and fourth quarters, respectively.
RESULTS OF OPERATIONS
Comparison of Three Months Ended June 30, 2006 to Three Months Ended June 30, 2005
Our consolidated net income for the second quarter of 2006 was $55.5 million, or $1.38 per diluted share, versus $17.4 million, or $0.56 per diluted share, in the second quarter of 2005.
The 2006 results include certain significant items that impact the comparability to 2005. These items are discussed in the “Second Quarter in Review and Current Events” section beginning on page 26. Our 2005 results also include certain items that impact comparability, including $14.7 million ($9.2 million after tax) of restructuring charges and $3.0 million ($1.9 million after tax) of mark-to-market fuel hedging gains. Excluding these items, our consolidated net income would have been $60.3 million for the second quarter of 2006 compared to $24.7 million in the second quarter of 2005. Financial and statistical data comparisons for Alaska and Horizon are shown on pages 22 and 23, respectively. On pages 24 and 25, we have included a reconciliation of reported non-GAAP financial measures to the most directly comparable GAAP financial measures.
Alaska Airlines Revenues
Operating revenues increased $94.1 million, or 15.3%, during the second quarter of 2006 as compared to the same period in 2005 due to a 9.5% increase in operating revenue per available seat mile (RASM) and a 5.2% increase in capacity. The increase in RASM resulted from an increase in load factors and a 7.6% increase in ticket yields resulting from higher ticket prices designed to offset increasing fuel prices, coupled with increases in freight and mail revenue and

other-net revenue as explained below. The increase in capacity is primarily the result of having a fleet of 113 operating aircraft at June 30, 2006 compared to 109 at June 30, 2005.
Load factor increased 1.4 percentage points to 79.3% for the second quarter of 2006 due to a 7.2% increase in passenger traffic outpacing the 5.2% increase in capacity. We expect to continue to see year-over-year improvements in load factors, yields and passenger unit revenues through the remainder of 2006, similar to the quarter-over-quarter improvements seen in the second quarter.
Freight and mail revenues increased $1.7 million, or 7.1%, primarily due to higher mail and freight yields and fuel surcharges that we added to our freight services beginning in the third quarter of 2005, offset by lower volumes.
Other-net revenues increased $6.3 million, or 20.2%, due to an increase in Mileage Plan revenues, resulting from higher award redemption on our partner airlines and an increase in cash receipts from miles sold, of which a portion is recognized immediately.
Alaska Airlines Expenses
Total operating expenses increased $48.7 million, or 8.2%, as compared to the same period in 2005. The increase in operating expenses is largely due to the significant increase in aircraft fuel, increases in wages and benefits and variable incentive pay for all employee groups, contracted services, and selling expenses, offset by a decline in aircraft maintenance and restructuring charges. Operating expenses per ASM increased 2.8% from 10.66 cents in the second quarter of 2005 to 10.96 cents in the second quarter of 2006. Operating expense per ASM excluding fuel and restructuring charges decreased by 2.1% to 7.92 cents per ASM compared to 8.09 cents per ASM in 2005. Our estimates of costs per ASM excluding fuel and restructuring adjustments for the third-quarter, fourth-quarter, and full-year targets for 2006 are 7.4 cents, 7.6 cents, and 7.7 cents, respectively. Our goal for 2006 is 7.65 cents per ASM. However, we are feeling some pressure from higher-than-expected costs for variable incentive pay, higher wages, and revenue-related costs. We are working to find ways to offset these costs.
Explanations of significant period-over-period changes in the components of operating expenses are as follows:
 
 	•	 	Wages and benefits increased by $6.8 million, or 3.8%, during the second quarter of 2006 compared to the same period in 2005 primarily due to the following:	
 
 	•	 	a $2.7 million signing bonus resulting from the new four-year contract with our flight attendants ratified during the second quarter of 2006;	
 
 	•	 	market-based pay adjustments for our non-union personnel in the spring of 2006 and an increase in stock-based compensation expense following the adoption of SFAS 123R;	
 
 	•	 	an increase in mechanics wages resulting from the contract ratified in the fourth quarter of 2005;	
 
29

Table of Contents
 	•	 	increased medical and pension costs from the prior year primarily driven by a $3.9 million increase in our retiree medical accrual; and	
 
 	•	 	a 2.2% increase in the average number of full-time equivalent employees from 9,144 in 2005 to 9,347 in 2006.	
The year-over-year increase in wages was partially offset by the following:
 
 	•	 	the reduction in pilot wages resulting from the pilot contract that took effect in May 2005; and	
 
 	•	 	the subcontracting of our ramp services operation in Seattle in the second quarter of 2005.	
 
 	•	 	Variable incentive pay increased $5.7 million, or 300.0%, over the same period in 2005, primarily due to an increase in our forecast of 2006 profit. Air Group maintains several incentive plans that collectively cover all of our employees. These plans include both operational and financial performance metrics that, to a large extent, are based on certain annual profitability targets. If our actual 2006 results differ materially from our forecast, our expense in the second half of 2006 could be significantly different than the charge in the first six months.	
 
 	•	 	Contracted services increased $2.6 million, or 8.2%, due largely to the subcontracting of the Company’s Seattle ramp operations in May 2005.	
 
 	•	 	Aircraft fuel increased $46.1 million, or 36.1%, due primarily to continued rise in fuel prices. As mentioned earlier, we began recording all fuel hedging gains and losses in aircraft fuel during the first quarter of 2006 and have reclassified prior periods to conform to the current period presentation. For the second quarter of 2006, aircraft fuel includes $3.3 million of mark-to-market losses related to hedges that settle in future periods, net of the reclassification of previously recorded mark-to-market gains on settled hedges, compared to $2.6 million of gains during the same period of 2005. Additionally, aircraft fuel expense includes $29.6 million and $24.5 million of gains from settled hedges during the second quarter of 2006 and 2005, respectively. After excluding mark-to-market gains and losses recorded during the quarter, our “economic,” or net, fuel expense increased $40.2 million, or 30.9%, over the same period in 2005. Our economic fuel cost per gallon increased 27.0% over the second quarter of 2005 from $1.51 to $1.92. We expect significant year-over-year increases in fuel cost throughout the remainder of 2006.	
See page 24 for a table summarizing fuel cost per gallon realized by Alaska (the economic cost per gallon) and the cost per gallon on a GAAP basis (including all hedging gains and losses).

Table of Contents
 	•	 	Aircraft maintenance decreased by $8.3 million, or 16.5%, compared to the prior year quarter primarily due to fewer scheduled and unexpected airframe and engine maintenance events, lower airframe costs per event due to renegotiated contracts with our outside vendors, and savings from process improvement initiatives. Our current expectation is that aircraft maintenance costs will be down approximately $16 million to $20 million for the full year 2006 compared to 2005.	
 
 	•	 	Selling expense increased $5.9 million, or 17.9%, compared to the same period in 2005. This is primarily due to an increase in our accrual for Mileage Plan awards and an increase in revenue-related expenses such as credit card and codeshare commissions resulting from the rise in revenues over the prior period.	
Horizon Air Revenues
For the second quarter of 2006, operating revenues increased $22.1 million, or 15.7%, compared to 2005. This increase reflects a 9.0% increase in RASM and a 6.1% increase in capacity.
The capacity increase is due to the addition of one CRJ700 in January 2006, one Q400 that began operating in June 2006, and increased flying for Frontier. Revenue and capacity from the Frontier contract flying represented approximately 8% of passenger revenues and 24% of capacity during the second quarter of 2006, similar to the prior year. The overall RASM increase from the prior year period comes from a 12.3% RASM increase in native network flying, offset by a 6.2% decline in RASM from the Frontier contract flying. The Frontier decline is a function of a 14.9% increase in capacity coupled with a fee arrangement based on certain metrics that do not correspond to capacity. As such, the per-unit revenues become diluted as more capacity is added. Passenger load factor increased 3.6 percentage points to 76.6% due to continued increase in demand. Passenger yield increased 5.3% to 23.25 cents benefiting from industry-wide fare increases designed to offset rising fuel prices.
Horizon Air Expenses
Operating expenses increased $24.0 million, or 18.7%, as compared to the same period in 2005. Operating expenses per ASM increased 11.8% from 15.14 cents in the second quarter of 2005 to 16.93 cents in the second quarter of 2006. Operating expenses per ASM excluding fuel increased 9.8% to 14.03 cents as compared to the same period in 2005. Our estimates of cost per ASM excluding fuel for the third quarter, fourth quarter and full year 2006 are 13.9 cents, 14.7 cents and 14.2 cents, respectively.
Explanations of significant period-over-period changes in the components of operating expenses are as follows:
 
 	•	 	Wages and benefits increased $4.5 million, or 10.7%, reflecting an increase in the average number of full-time equivalent employees and wages per employee.	
 
31

Table of Contents
 	•	 	Variable incentive pay increased $1.9 million, or 172.7%, for the same reasons cited in the Alaska discussion above.	
 
 	•	 	Aircraft fuel increased $6.0 million, or 29.9%, due to the continued rise in fuel prices coupled with a 2.3% increase in fuel consumption. As mentioned above, during the first quarter of 2006 we began recording all fuel hedging gains and losses in aircraft fuel and have reclassified prior periods to conform to the current period presentation. For the second quarter of 2006, aircraft fuel includes $0.5 million of mark-to-market losses related to hedges that settle in future periods, net of the reclassification of previously recorded mark-to-market gains on settled hedges, compared to $0.4 million of mark-to-market gains during the same period of 2005. Additionally, aircraft fuel includes $4.8 million and $3.7 million of gains from settled hedges during the second quarter of 2006 and 2005, respectively. After excluding mark-to-market gains and losses recorded during the quarter, our “economic,” or net, fuel expense increased $5.1 million, or 24.9%, over the same period in 2005, due to the continued rise in fuel prices. Our economic fuel cost per gallon increased 22.0% over the second quarter of 2005, from $1.59 to $1.94.	
See page 25 for a table summarizing fuel cost per gallon realized by Horizon (the economic cost per gallon) and the cost per gallon on a GAAP basis (including all hedging gains and losses).
 
 	•	 	Aircraft maintenance expense increased $7.8 million, or 96.3%, primarily due to a higher number of routine maintenance activities and engine overhauls for the Q200 and Q400 fleets and fewer aircraft covered by warranty. Our current expectation is that aircraft maintenance costs will be approximately $30 million to $33 million higher for the full year 2006 compared to 2005 as a result of the increase in scheduled maintenance activities.	
 
 	•	 	Other operating expense increased $2.4 million, or 25.0%, primarily due to higher crew expenses, passenger remuneration and property taxes.	
Consolidated Nonoperating Income (Expense)
Net nonoperating income (expense) was $1.0 million in the second quarter of 2006 compared to $(6.9) million during the same period of 2005. Interest income increased $7.0 million compared to the second quarter of 2005, primarily due to the higher average cash and marketable securities balance and higher average portfolio returns. Interest expense increased $2.8 million due to interest rate increases on our variable-rate debt, new debt arrangements in the first six months of 2006, the increased balance on our pre-delivery payment facility, and the changes to some of our variable-rate debt arrangements to slightly higher fixed rates. The increase was offset by the conversion of our $150 million senior convertible notes to equity in the April 2006, which eliminates further interest expense on those notes. Capitalized interest increased $4.5 million

Table of Contents
from $1.3 million in the second quarter of 2005 to $5.8 million in the second quarter of 2006. This increase is due to the significant increase in deposits for future flight equipment resulting from our new aircraft purchase agreements for B737-800 and Bombardier Q400 aircraft.
Consolidated Income Tax Expense (Benefit)
See discussion below under “Comparison of Six Months Ended June 30, 2006 to Six Months Ended June 30, 2005.”
Comparison of Six Months Ended June 30, 2006 to Six Months Ended June 30, 2005
Our consolidated net loss for the six months ended June 30, 2006 was $23.6 million, or $0.66 per diluted share, versus a net loss of $63.1 million, or $1.82 per diluted share, during the same period of 2005.
Both the 2006 and 2005 results include certain significant items that impact the comparability of the six-month periods. Our 2006 consolidated net income includes a $131.1 million charge ($81.9 million after tax) associated with the impairment of our MD-80 fleet in the first quarter, the $3.8 million charge ($2.4 million after tax) associated with our flight attendant severance package noted above, and $3.8 million ($2.4 million after tax) of mark-to-market fuel hedging losses. Our 2005 consolidated net loss includes a $144.7 million pre-tax ($90.4 million after tax) charge resulting from the change in the method of accounting for major airframe and engine overhauls as discussed in Note 5 to the consolidated financial statements. Additionally, we recorded restructuring charges of $22.1 million ($13.8 million, net of tax) in the first six months of 2005 related primarily to the termination of the lease at our Oakland heavy maintenance base and severance and related costs resulting from the subcontracting of the ramp services operation in Seattle. The 2005 results also include mark-to-market fuel hedging gains of $93.0 million ($58.1 million after tax). Excluding these items, our consolidated net income would have been $63.1 million for the first six months of 2006 compared to a $17.0 million loss during the same period of 2005. Financial and statistical data comparisons for Alaska and Horizon are shown on pages 22 and 23, respectively. On pages 24 and 25, we have included a reconciliation of reported non-GAAP financial measures to the most directly comparable GAAP financial measures. A discussion of the six-month data follows.
Alaska Airlines Revenues
Operating revenues increased $160.8 million, or 14.1%, during the first six months of 2006 as compared to the same period in 2005 due primarily to a 9.5% increase in operating revenue per available seat mile (RASM) and a 4.2% increase in capacity. The increase in RASM resulted from an increase in load factors and an 8.2% increase in ticket yields resulting from higher ticket prices designed to offset rising fuel prices, coupled with increases in freight and mail revenue and other-net revenue as explained below. The increase in capacity is primarily the result of having a fleet of 113 operating aircraft at June 30, 2006 compared to 109 at June 30, 2005.
 
33

Table of Contents
Load factor increased 1.2 percentage points to 76.5% during the first six months of 2006 due primarily to a 6.0% increase in passenger traffic outpacing the 4.2% increase in capacity.
Freight and mail revenues increased $2.9 million, or 6.7%, compared to the same period in 2005 primarily due to higher mail and freight yields and fuel surcharges that we added to our freight services beginning in the third quarter of 2005, offset by lower volumes.
Other-net revenues increased $6.3 million, or 9.9%, due to an increase in Mileage Plan revenues, resulting from higher award redemption on our partner airlines and an increase in cash receipts from miles sold, of which a portion is recognized immediately.
Alaska Airlines Expenses
Total operating expenses increased $262.5 million, or 24.1%, as compared to the same period in 2005. This increase is largely due to the impairment charge in the first quarter of 2006, significant increases in aircraft fuel, increases in variable incentive pay, contracted services, selling expenses, and depreciation and amortization, offset by a decline in wages and benefits, aircraft maintenance, and restructuring charges and adjustments. Operating expenses per ASM increased 19.0% to 11.90 cents in the first six months of 2006 from 10.00 cents during the same period in 2005. Operating expense per ASM excluding fuel, restructuring and impairment charges decreased 4.5% as compared to the same period in 2005.
Explanations of significant period-over-period changes in the components of operating expenses are as follows:
 
 	•	 	Wages and benefits decreased $14.4 million, or 3.8%, during the first six months of 2006 compared to the same period in 2005 primarily due to the following:	
 
 	•	 	the reduction in pilot wages resulting from the pilot contract that took effect in May 2005; and	
 
 	•	 	the subcontracting of our ramp services operation in Seattle in the second quarter of 2005.	
The decrease over prior year was partially offset by the following:
 
 	•	 	a $2.7 million signing bonus resulting from the new four-year contract with our flight attendants ratified during the second quarter of 2006;	
 
 	•	 	market-based pay adjustments for our non-union personnel in the spring of 2006 and an increase in stock-based compensation expense following the adoption of SFAS 123R;	
 
 	•	 	an increase in mechanics wages resulting from the contract ratified in the fourth quarter of 2005; and	
 
34

Table of Contents
 	•	 	increased medical and pension costs from the prior year primarily driven by a $3.9 million increase in our retiree medical accrual.	
 
 	•	 	Variable incentive pay increased $9.3 million, or 197.9%, over the same period in 2005, primarily due to an increase in forecasted 2006 profit. Air Group maintains several incentive plans that collectively cover all of our employees. These plans include both operational and financial performance metrics that, to a large extent, are based on certain annual profitability targets. If our actual 2006 results differ materially from our forecast, our expense in the second half of 2006 could be significantly different than the charge in the first six months.	
 
 	•	 	Contracted services increased $6.7 million, or 11.3%, primarily due to the subcontracting of the Company’s Seattle ramp operations in May 2005.	
 
 	•	 	Aircraft fuel increased $153.9 million, or 95.1%, primarily due to a significant decline in the mark-to-market fuel hedging gains in 2006 compared to 2005 and the continued rise in fuel prices. As mentioned above, during the first quarter of 2006 we began recording all fuel hedging gains and losses in aircraft fuel and have reclassified prior periods to conform to the current period presentation. For the first six months of 2006, aircraft fuel includes $4.5 million of mark-to-market losses related to hedges that settle in future periods, net of the reclassification of previously recorded mark-to-market gains on settled hedges, compared to $80.3 million of gains during the same period of 2005. Additionally, aircraft fuel expense includes $55.4 million and $43.6 million of gains from settled hedges during the first six months of 2006 and 2005, respectively. After excluding mark-to-market gains and losses recorded during the period, our “economic,” or net, fuel expense increased $69.1 million, or 28.5%, over the same period in 2005. Our economic fuel cost per gallon increased 26.4% over the first six months of 2005 from $1.42 to $1.80.	
See page 24 for a table summarizing fuel cost per gallon realized by Alaska (the economic cost per gallon) and the cost per gallon on a GAAP basis (including all hedging gains and losses).
 
 	•	 	Aircraft maintenance decreased by $14.1 million, or 14.1%, mostly due to fewer scheduled and unexpected airframe and engine maintenance events, lower per-event costs due to renegotiated contracts with our outside vendors, and savings from process improvement initiatives.	
 
 	•	 	Selling expense increased $6.6 million, or 9.9%, primarily due to an increase in our accrual for Mileage Plan awards and an increase in revenue-related expenses such as credit card and codeshare commissions resulting from the rise in revenues over the prior period.	
 
35

Table of Contents
 	•	 	Depreciation and amortization increased $3.4 million, or 5.6%, compared to the same period in 2005. This increase is primarily due to two new B737-800 aircraft delivered during 2005 and four additional new B737-800 aircraft delivered in the first six months of 2006, offset by the lower depreciable base on the MD-80 fleet resulting from the impairment charge recorded in the first quarter of 2006.	
Horizon Air Revenues
For the first six months of 2006, operating revenues increased $47.1 million, or 18.0% compared to 2005. This increase reflects an 8.2% increase in RASM and a 9.0% increase in capacity.
The capacity increase is primarily due to the addition of one CRJ700 in January 2006, one Q400 that began operating in June 2006, increasing the capacity of the Q400 fleet from 70 to 74 seats in the second quarter of 2005, and increased flying for Frontier. Revenue and capacity from the Frontier contract flying represented approximately 9% of passenger revenues and 24% of capacity during the first six months of 2006, similar to the prior year. The overall RASM increase from the prior year period comes from an 11.2% RASM increase in our native network flying, offset by a 7.2% decline in RASM from the Frontier contract flying. The Frontier decline is a function of a 15.8% increase in capacity coupled with a fee arrangement based on certain metrics that do not correspond to capacity. As such, the per-unit revenues become diluted as more capacity is added. Passenger load factor increased 2.6 percentage points to 73.7% due to continued increase in demand. Passenger yield increased 5.8% to 23.22 cents benefiting from industry-wide fare increases designed to offset rising fuel prices.
Horizon Air Expenses
Operating expenses for the first six months of 2006 increased $54.1 million, or 22.1%, compared to the same period in 2005. Operating expenses per ASM increased 12.0% as compared to 2005. Operating expenses per ASM excluding fuel increased 4.8% as compared to the same period in 2005.
Explanations of other significant period-over-period changes in the components of operating expenses are as follows:
 
 	•	 	Wages and benefits increased $9.1 million, or 10.8%, reflecting an increase in the average number of full-time equivalent employees and wages per employee.	
 
 	•	 	Variable incentive pay increased $2.7 million, or 112.5%, over the same period in 2005, due to the same reasons noted above in the Alaska discussion.	
 
 	•	 	Aircraft fuel increased $22.8 million, or 93.4%, primarily due to a decline in the mark-to-market fuel hedging gains in 2006 compared to 2005 and the continued rise in fuel prices.	
 
36

Table of Contents
 	For the first six months of 2006, aircraft fuel includes $0.7 million of mark-to-market gains related to hedges that settle in future periods, net of the reclassification of previously recorded mark-to-market gains on settled hedges, compared to $12.7 million of mark-to-market gains during the same period of 2005. Additionally, aircraft fuel includes $9.0 million and $6.5 million of gains from settled hedges during the first six months of 2006 and 2005, respectively. After excluding mark-to-market gains and losses recorded during the quarter, our “economic,” or net, fuel expense increased $10.8 million, or 29.1%, over the same period in 2005, due to the continued rise in fuel prices. Our economic fuel cost per gallon increased 23.2% over 2005, from $1.49 to $1.84.	
See page 25 for a table summarizing fuel cost per gallon realized by Horizon (the economic cost per gallon) and the cost per gallon on a GAAP basis (including all hedging gains and losses).
 
 	•	 	Aircraft maintenance expense increased $13.6 million, or 70.8%, primarily due to a higher number of routine maintenance activities and engine overhauls for the Q200 and Q400 fleets and fewer aircraft covered by warranty.	
 
 	•	 	Selling expenses increased by $2.4 million, or 17.1%, mostly due to increases in commission expense resulting from the revenue improvement.	
 
 	•	 	Other operating expenses increased by $2.5 million, or 12.0%, primarily due to higher crew expenses, passenger remuneration and property taxes.	
Consolidated Nonoperating Income (Expense)
Net nonoperating income (expense) was $(3.2) million in the first six months of 2006 compared to $(17.2) million during the same period of 2005. Interest income increased $12.2 million compared to 2005, primarily due to higher average portfolio returns and a higher average cash and marketable securities balance. Interest expense increased $7.8 million primarily due to interest rate increases on our variable-rate debt, new debt arrangements in the first six months of 2006, the increased balance on our pre-delivery payment facility, and the changes to some of our variable-rate debt arrangements to slightly higher fixed rates. This increase was offset by the conversion of our $150 million senior convertible notes to equity in April 2006, which eliminates further interest expense on those notes. Capitalized interest increased $8.4 million from $2.1 million in 2005 to $10.5 million during 2006. This is due to the significant increase in deposits for future flight equipment in connection with our new aircraft purchase agreements for B737-800 and Bombardier Q400 aircraft.
Consolidated Income Tax Expense (Benefit)
Accounting standards require us to provide for income taxes each quarter based on either our estimate of the effective tax rate for the full year or the actual year-to-date effective tax rate if it

Table of Contents
is our best estimate of our annual expectation. For the first six months of 2006, we used the estimate of the effective tax rate for the full year as we believe it to be a better estimate than the actual year-to-date effective tax rate. Our effective income tax rate on pre-tax income for the six months ended June 30, 2006 was 51.1%. The six months ended June 30, 2006 also includes $5.5 million of tax benefits associated with the reduction of certain tax contingency accruals for periods for which the statute of limitations expired in 2006. Excluding this benefit, our effective tax rate six months ended June 30, 2006 would have been 39.8%, which is the estimated effective tax rate for the full year 2006. In arriving at this rate, we considered a variety of factors, including year-to-date pre-tax results, the U.S. federal rate of 35%, estimated year-to-date nondeductible expenses and estimated state income taxes. We evaluate our tax rate each quarter and make adjustments when necessary. Our final effective tax rate for the full year is highly dependent on the level of pre-tax income or loss and the magnitude of any nondeductible expenses in relation to that pre-tax amount.

Our debt-to-capital ratio decreased from December 31, 2005 primarily due to the conversion to equity of our senior convertible notes in April 2006, partially offset by a $23.6 million net loss for the six months, and by an increase in our outstanding debt in connection with new aircraft-secured debt arrangements in the first six months of 2006.
During the six months ended June 30, 2006, our cash and marketable securities increased $120.8 million to just over $1.1 billion. The following discussion summarizes the primary drivers of the increase.

Table of Contents
Cash Provided by (Used in) Operating Activities
During the first six months of 2006, net cash provided by operating activities was $237.4 million, compared to $90.3 million during the same period of 2005. The improvement was driven by significantly higher operating revenues and a decline in cash payments made for severance compared to the prior year, offset by continued increases in fuel costs and $71.9 million in cash contributions to our defined benefit pension plan during the first six months of 2006 compared to $38.6 million during the same period of 2005. The increase in cash contributions is due to the fact that we made all of our 2006 planned contributions in the first six months of 2006, whereas in 2005, we made $69.3 million of contributions over nine months.
Cash Provided by (Used in) Investing Activities
Cash used in investing activities was $348.7 million during the first six months of 2006, compared to $82.8 million during the same period of 2005. During the first six months of 2006, we had net purchases of marketable securities of $52.5 million and used $299.9 million for property and equipment additions, net of proceeds from asset dispositions. During the six months ended June 30, 2006, our aircraft-related capital expenditures, net of aircraft deposits returned and proceeds from asset dispositions, increased $63.1 million as compared to the same period of 2005, primarily as a result of the increase in pre-delivery payments made for future aircraft deliveries and the purchase of four B737-800’s, two Q400’s and one CRJ 700 in the first six months of 2006, compared to two B737-800’s in 2005. We expect capital expenditures to be approximately $630 million for the full year 2006 and $680 million in 2007.
Cash Provided by (Used in) Financing Activities
Net cash provided by financing activities was $178.2 million during the first six months of 2006 compared to net cash used of $4.3 million during the same period of 2005. We obtained debt financing for three new B737-800 aircraft and one CRJ700 purchased in the first six months of 2006. Additionally, there was a net increase of $74.4 million in our pre-delivery payment facility. Finally, we had $17.9 million in proceeds from the issuance of common stock through stock option exercises and our employee stock purchase plan, compared to $2.2 million during the same period of 2005. Offsetting these increases were normal long-term debt payments of $29.2 million during 2006.
We plan to meet our capital and operating commitments through internally generated funds from operations and cash and marketable securities on hand at June 30, 2006, along with additional debt financing and proceeds from our pre-delivery payment facility.
Bank Line of Credit Facility
Alaska’s $160 million variable-rate credit facility restricts Alaska from distributing any funds to Air Group in the form of dividends and limits the amount of funds Alaska can loan to Air Group. As of June 30, 2006, $300.0 million was available to loan to Air Group without violating the covenants in the credit facility. As of June 30, 2006, there are no outstanding borrowings on this credit facility and we have no immediate plans to draw on the facility.

Contractual Obligations, Commitments and Off-Balance Sheet Arrangements
Aircraft Purchase Commitments
At June 30, 2006, we had firm orders for 53 aircraft requiring aggregate payments of approximately $1.3 billion, as set forth below. In addition, Alaska has options to acquire 29 additional B737-800s and purchase rights for 27 more. Subsequent to June 30, 2006, Alaska converted one of its options into a firm order to be delivered in 2008. Alaska also has entered into operating lease agreements for two B737-800 aircraft to be delivered in late 2006 and has extended lease terms on five aircraft including three B737-700s and two B737-400s. Horizon has options to acquire 19 Q400s and 15 CRJ700s. Alaska and Horizon expect to finance the firm orders and, to the extent exercised, the option aircraft through operating lease arrangements, long-term debt or internally generated cash.
During the first six months of 2006, Alaska received delivery of four B737-800 aircraft, all of which were paid for with cash upon delivery and subsequently three of which were financed with fixed-rate debt arrangements. The fourth aircraft was debt financed subsequent to June 30, 2006 under a variable-rate arrangement. Horizon took delivery of two used Q400 aircraft, both of which were acquired using cash on hand, and one CRJ700, which was financed with a variable-rate debt arrangement.
Subsequent to the end of the quarter, Alaska executed an agreement to sell six of our B737-200 aircraft. Title to each aircraft will be transferred as each of the aircraft leaves our fleet over the next several months, with the last aircraft expected to leave our fleet in April 2007.
The following table summarizes aircraft purchase commitments as of June 30, 2006 and payments by year:

As noted, Alaska has announced a plan to transition to a single Boeing 737 fleet type by the end of 2008, which includes an acceleration of the retirement of its MD-80 fleet. As a result, we expect to exercise additional options and purchase rights on our Boeing 737-800 order in the future in addition to the firm deliveries that are identified in the contractual table above.

Item 3.	Quantitative and Qualitative Disclosures about Market Risk	
There have been no material changes in market risk from the information provided in Item 7A “Quantitative and Qualitative Disclosure About Market Risk” in our 2005 Form 10-K except as follows:
Market Risk – Aircraft Fuel
We utilize call options, collar structures, and swap agreements as hedges to decrease our exposure to the volatility of jet fuel prices. We believe there is risk in not hedging against the possibility of fuel price increases. See Note 4 in the condensed consolidated financial statements for a summary of our hedge positions. We estimate that a 10% increase or decrease in crude oil prices as of June 30, 2006 would increase or decrease the fair value of our hedge portfolio by approximately $29.0 million and $28.7 million, respectively.

Table of Contents
Additionally, we have entered into fuel purchase contracts that fix the refining margin we pay for approximately 50% and 15% of Alaska’s fuel consumption in the third and fourth quarters, respectively.
Please refer to pages 24 and 25, as well as to Note 4 in the condensed consolidated financial statements, for company-specific data on the results of our fuel-hedging program.
 
ITEM 4.	Controls and Procedures	
Evaluation of Disclosure Controls and Procedures
As of June 30, 2006, an evaluation was performed under the supervision and with the participation of our management, including our chief executive officer and chief financial officer (collectively, our “certifying officers”), of the effectiveness of the design and operation of our disclosure controls and procedures. These disclosure controls and procedures are designed to ensure that the information required to be disclosed by us in our periodic reports filed with the Securities and Exchange Commission (the SEC) is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and that the information is communicated to our certifying officers on a timely basis.
Our certifying officers concluded, based on their evaluation, that disclosure controls and procedures were effective.
Changes in Internal Control over Financial Reporting
The Company has historically maintained accounting and payroll departments at both Alaska Airlines and Horizon Air. During the third quarter of 2006, these separate departments will be combined into one Air Group accounting and payroll function with an objective of improving economies of scale and standardizing processes across the Company. In anticipation of that change, during the second quarter, Horizon’s general ledger system was converted to the same system historically used by Alaska. There were no changes in the Company’s internal control over financial reporting, including the change described above, identified in management’s evaluation during the second quarter of 2006 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
We intend to regularly review and evaluate the design and effectiveness of our disclosure controls and procedures and internal control over financial reporting on an ongoing basis and to improve these controls and procedures over time and to correct any deficiencies that we may discover in the future. While we believe the present design of our disclosure controls and procedures and internal control over financial reporting are effective, future events affecting our business may cause us to modify our controls and procedures.

PART II OTHER INFORMATION
 
ITEM 1.	Legal Proceedings	
In April 2006, the federal district court in Seattle dismissed a counterclaim by the International Association of Machinists (IAM) alleging that Alaska violated the Railway Labor Act status quo and engaged in bad faith bargaining. At the same time, the court also granted voluntary dismissal of Alaska’s lawsuit against the IAM seeking to compel arbitration of dispute regarding the permissibility of subcontracting of Alaska’s ramp service operation in Seattle. The appeal period has expired and these matters are closed.
However, in addition to the court cases, the IAM filed a grievance against Alaska alleging that Alaska violated the collective bargaining agreement by, among other things, subcontracting the ramp service operation in Seattle when the parties could not reach agreement on an acceptable labor contract. This matter is scheduled for arbitration in August and December of 2006.
We are also a party to routine commercial and employment litigation incidental to our business and with respect to which no material liability is expected.
Management believes the ultimate disposition of these matters is not likely to materially affect our financial position or results of operations. This belief is based on management’s current understanding of the relevant law and facts, and it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of judges, juries, and arbitrators.
 
ITEM 1A.	Risk Factors	
In the third quarter, Horizon expects to implement a new maintenance and inventory system. There is a risk that this system implementation could cause disruption in our operations. As such, we have modified one of the risk factors from our 2005 Form 10-K as follows.
We rely heavily on automated systems to operate our business and any failure of these systems could harm our business.
We depend on automated systems to operate our business, including our computerized airline reservation system, our telecommunication systems, our website, our maintenance systems, and other systems. We also issue a substantial number of our tickets to passengers as electronic tickets. We depend on our computerized reservation system to be able to issue, track and accept these electronic tickets. In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic and deliver important flight information. Substantial or repeated website, reservations system or telecommunication systems failures could reduce the attractiveness of our services and cause our customers to purchase tickets from another airline. In addition, we rely on other automated systems for crew scheduling, flight dispatch, maintenance tracking, and other operational needs. Any disruption in or changes

to these systems could result in the loss of important data, increase our expenses and possibly cause us to temporarily cease our operations.
In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part 1, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2005, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
