Note 5. Frequent Flyer Program

(a) Change in Accounting Principle

    In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin 101 (SAB 101), Revenue Recognition in Financial Statements. SAB 101 gives specific guidance on the conditions that must be met before revenue may be recognized, and in June 2000 Alaska changed its method of accounting for the sale of miles in its Mileage Plan. Under the new method, a majority of the sales proceeds is deferred, and recognized when the award transportation is provided. The deferred proceeds are recognized as passenger revenue for awards issued on Alaska and as other revenue-net for awards issued on other airlines. In connection with the change, Alaska recognized a $56.9 million cumulative effect charge, net of income taxes of $35.6 million, effective January 1, 2000. Accordingly, results for the first quarter 2000 have been restated.

(b) Special Charge—Mileage Plan

    In June 2000, Alaska recorded a $24.0 million special charge to recognize the increased incremental cost of travel awards earned by flying on Alaska and travel partners. The higher cost is due to an increase in the estimated costs Alaska incurs to acquire awards on other airlines for its Mileage Plan members, as well as lower assumed forfeiture of miles.

ITEM 2. Management's Discussion and Analysis of Results of Operations and Financial Condition

Forward-Looking Information

    This report may contain forward-looking statements that are based on the best information currently available to management. These forward-looking statements are intended to be 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. Forward-looking statements are indicated by phrases such as "will", "should", "the Company believes", "we expect" or any other language indicating a prediction of future events. There can be no assurance that actual developments will be those anticipated by the Company. Actual results could differ materially from those projected as a result of a number of factors, some of which the Company cannot predict or control. For a discussion of these factors, please see Item 1 of the Company's Annual Report on Form 10-K for the year ended December 31, 1999.

Results of Operations

Third Quarter 2000 Compared with Third Quarter 1999

    The consolidated net income for the third quarter of 2000 was $15.9 million, or $0.60 per share (diluted), compared with $54.9 million, or $2.07 per share (diluted), in 1999. Consolidated operating income for the third quarter of 2000 was $37.2 million compared to $86.3 million for 1999. The $49.1 million reduction in operating income was largely due to higher fuel prices, and higher labor and aircraft maintenance costs. Financial and statistical data for Alaska and Horizon is shown on pages 11 and 12. A discussion of this data follows.

Alaska Airlines

Revenues

    Capacity was reduced 3.2% in order to improve schedule reliability. Traffic dropped 1.2%, resulting in a 1.5 point increase in passenger load factor. Passenger yields were up 4.9% (4.0% excluding the impact of a new accounting method for the sale of miles), primarily due to fuel-related fare increases. Yields were up in substantially all major markets. The lower traffic combined with the higher yield resulted in a 3.7% increase in passenger revenue. In spite of the loss of the marketing alliance with Canadian Airlines in August 2000, traffic and load factor in the Canadian market increased in September 2000.

    Freight and mail revenues decreased 9.6%, primarily due to lower freight volumes that resulted from 4.7% fewer flights operated, lower seafood shipments and more competition.

    Other-net revenues decreased $5.6 million (30.1%), due to a change in accounting for the sale of miles in Alaska's frequent flyer program. If the new accounting method had been in effect in 1999, other-net revenues would have increased $1.4 million (11.6%).

Expenses

    Operating expenses grew by 12.6% as a result of an 16.3% increase in cost per ASM. The increase in cost per ASM was largely due to higher fuel prices, higher labor and aircraft maintenance costs and lower ASMs. Explanations of significant year-over-year changes in the components of operating expenses are as follows:

•
Wages and benefits increased 15.6% due to a 3.6% increase in the number of employees combined with an 11.5% increase in average wages and benefits per employee. Management employees were hired in many areas (e.g. maintenance and quality control, computer services, training, marketing and employee services) to better manage the existing operations. The number of pilots and flight attendants increased, in spite of a reduction in capacity, due to

14

training requirements. The 2000 results include a $2.9 million charge for a flight attendant early retirement program. Absent this charge, average wages and benefits per employee increased 9.4%. New labor contracts for flight attendants, passenger service and ramp service employees, combined with longevity increases for pilots, and annual merit raises for management employees all contributed to the higher average wage rates.•
Contracted services increased 16%. The 2000 results include a $0.6 million charge for aircraft accident costs not expected to be covered by insurance. Absent this charge, contracted services increased 11% due to new costs for processing marketing information, higher contract labor and security costs, and higher rates for ground handling services.

•
Fuel expense increased 38%, primarily due to a 44% increase in the cost of fuel. The fuel consumption rate decreased 2% due to the use of more fuel efficient B737-700 aircraft. Fuel hedging saved $1.9 million.

•
Maintenance expense increased 36%, due to greater use of outside contractors for airframe checks, a greater number of such checks and increased expenses for engine overhauls.

•
Aircraft rent expense decreased 12%, due to leasing four fewer MD-80 aircraft and two fewer B737-400 aircraft.

•
Commission expense decreased 36% on a 4% increase in passenger revenue. The commission rate paid to travel agents decreased from 8% to 5%. In 2000, 63% of ticket sales were made through travel agents, versus 67% in 1999. In 2000, 10.5% of ticket sales were made through Alaska's Internet web site versus 5.8% in 1999.

•
Other selling expense increased 24%, higher than the 4% increase in passenger revenue, due to increased expenses for Mileage Plan awards.

•
Depreciation increased 31%, primarily due to owning 10 more aircraft in 2000.

•
Other expense increased 21%, primarily due to higher expenditures for legal fees, passenger remuneration, hotel and flight crew meals, professional services and recruiting.

Horizon Air

Revenues

    Capacity grew by 4.0%, primarily due to added flights in the Canada and Montana markets. Traffic grew by 0.5%, resulting in a 2.2 point decrease in passenger load factor. Loss of the marketing alliance with Canadian Airlines and fires in Montana contributed to the lower load factor. Passenger yields were up 3.6%, largely due to "fuel surcharge" fare increases. The higher traffic combined with the higher yield resulted in a 4.3% increase in passenger revenue.

Expenses

    Operating expenses grew by 10.8% as a result of a 4.0% increase in capacity and a 6.5% increase in cost per ASM. Explanations of significant year-over-year changes in the components of operating expenses are as follows:

•
Wages and benefits increased 10.8% due to a 4.9% increase in the number of employees combined with a 5.4% increase in average wages and benefits per employee. Employees were added to support 4.0% more block hours of flying and to prepare for growth in future periods.

•
Contracted services increased 13%, higher than the 4% increase in capacity, due to increased expenses for ground handling, security and employee recruiting.

15

•
Fuel expense increased 44%, due to a 4% increase in fuel consumption combined with a 40% increase in the cost of fuel.

•
Maintenance expense increased 40%, higher than the 4% increase in block hours, due in part to increased expenses related to the earlier than previously estimated timeframe for phasing out the Fokker F-28 jet aircraft.

•
Commission expense decreased 33% on a 4% increase in passenger revenue, because a smaller percentage of sales were made through travel agents and commission rates dropped from 8% to 5%.

•
Depreciation and amortization expense increased 26%, due in part to added depreciation on Fokker F-28 jet aircraft spare parts.

•
Landing fees and other rentals increased 19%, due to increased rates at Seattle and Portland airports.

    Consolidated Nonoperating Income (Expense)  Net nonoperating income decreased $3.5 million, due to higher interest expense resulting from new debt incurred in late 1999 and in the third quarter of 2000.

Nine Months 2000 Compared with Nine Months 1999

    In accordance with guidance provided in the SEC's Staff Accounting Bulletin 101, Alaska changed its method of accounting for the sale of miles in its Mileage Plan. In connection with the change, Alaska recognized a $56.9 million cumulative effect charge, net of income taxes of $35.6 million, effective January 1, 2000. The consolidated income before accounting change for the nine months ended September 30, 2000 was $15.5 million, or $0.59 per share (diluted), compared with $117.2 million, or $4.43 per share (diluted) in 1999. The consolidated operating income for the first nine months of 2000 was $33.7 million compared with an operating income of $180.2 million for 1999. A discussion of operating results for the two airlines follows.

    Alaska Airlines  Operating income decreased $131.0 million to $26.5 million in 2000, primarily due to higher fuel prices ($74.4 million) and a special charge related to Mileage Plan estimates ($24.0 million). Changes in operating revenues and operating expenses are generally due to the same reasons stated above in the third quarter comparison.

    Horizon Air  Operating income decreased to $8.0 million, resulting in a 2.4% operating margin as compared to a 7.5% margin in 1999. Operating revenue per ASM increased 0.4% to 19.38 cents, while operating expenses per ASM increased 6.0% to 18.91 cents. The changes in unit revenue and unit expense are generally due to the same reasons stated above in the third quarter comparison.

    Consolidated Nonoperating Income (Expense)  Net nonoperating income decreased $10.2 million, primarily due to higher interest expense resulting from new debt incurred in late 1999.

    The Company's cash and marketable securities portfolio increased by $54 million during the first nine months of 2000. Operating activities provided $251 million of cash during this period. Additional cash was provided by the issuance of $119 million of new debt. Another $39 million was provided by insurance proceeds from an aircraft accident and other asset dispositions. Cash was used for $336 million of capital expenditures, including the purchase of five new Boeing 737 aircraft, flight equipment deposits and airframe and engine overhauls, and for $20 million of debt repayment.

    Shareholders' equity decreased $39.8 million due to the net loss of $41.4 million, which was partly offset by stock issued under stock plans and changes in deferred compensation.

    Aircraft Accident  On January 31, 2000, Alaska Airlines flight 261 from Puerto Vallarta en route to San Francisco, went down in the water off the coast of California near Point Mugu. The flight carried 83 passengers and five crew members. There were no survivors. Consistent with industry standards, the Company maintains insurance against aircraft accidents. The Company expects substantially all accident response and civil litigation costs to be covered by insurance. However, any aircraft accident, even if fully insured, could cause a negative public perception of the Company with adverse financial consequences. Principally as a result of added maintenance inspections Alaska carried out after the accident, Alaska estimates that it canceled 6% of its flights in February and 3% of its flights in March.

    Safety Activities  In March 2000, to enhance existing lines of communication, Alaska established a "safety hotline" for employees to contact the chairman's office directly regarding any safety concern. In April 2000, an independent team of outside safety experts began a full audit of the maintenance, flight operations, hazardous materials handling and security areas of Alaska. The team presented its final report to Alaska in June 2000 and Alaska is implementing those recommendations. Alaska has also hired a vice president of safety, who reports directly to the chairman.

    Commitments  As of September 30, 2000, the Company had firm orders for 63 aircraft requiring aggregate payments of approximately $1.3 billion, as set forth below. In addition, Alaska has options to acquire 26 more B737s and Horizon has options to acquire 15 Dash 8-400s and 25 CRJ 700s. Alaska

17

and Horizon expect to finance the new planes with either leases, long-term debt or internally generated cash.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

    In December 1998, search warrants and a grand jury subpoena (for the U.S. District Court for the Northern District of California) were served on Alaska, initiating an investigation into the Company's Oakland maintenance base by the U.S. Attorney for the Northern District of California. Alaska has cooperated with the U.S. Attorney's initial and subsequent requests for information concerning the Company's maintenance operations. In addition, the Federal Aviation Administration (FAA) issued a letter of investigation (LOI) to Alaska relating to maintenance performed on an MD-80 aircraft. In April 1999, the FAA issued a notice of proposed civil penalty for $44,000. In July 1999, Alaska responded informally to the notice, disputing that any violation occurred, and to date the FAA has not taken any further action. The Company understands that information developed by the National Transportation Safety Board in connection with the crash of flight 261 on January 31, 2000 is being shared with the U.S. Attorney and that the U.S. Attorney is using this information, along with other records relating to the aircraft Alaska has produced, to evaluate whether any crimes were committed in connection with flight 261. To the Company's knowledge, no charges have been filed as a result of the grand jury investigation.

    Alaska is currently a defendant in a number of lawsuits relating to flight 261. The Company is unable to predict the amount of claims that may ultimately be made against it or how those claims might be resolved. Consistent with industry standards, the Company maintains insurance against aircraft accidents.

    In April 2000, the FAA began an audit of Alaska's maintenance and flight operations departments to ensure adherence to mandated procedures. During the audit, the FAA requested that Alaska take a number of actions, which Alaska has done or is currently implementing. In June 2000, the FAA informed Alaska that it was proposing to amend Alaska's operations specification to suspend the Company's ability to perform heavy maintenance on its aircraft. In June 2000, Alaska submitted an Airworthiness and Operations Action Plan describing numerous steps Alaska would take to address the FAA's concerns. In response to this plan the FAA withdrew its proposal. The FAA also requested that the Company submit a growth plan to demonstrate its ability to handle operationally its planned fleet additions. In June 2000, Alaska submitted its growth plan to the FAA. In July 2000, Alaska responded in writing to each of the FAA's findings from its April audit. The FAA has issued a number of LOIs stemming from the resulting increased FAA oversight. Alaska is investigating and responding to these LOIs, which may be followed by proposed civil penalties. The Company has not been informed what further actions, if any, the FAA intends to take with respect to these matters.

    The Company cannot predict the outcome of any of the pending civil or potential criminal proceedings described above. As a result, the Company can give no assurance that these proceedings, if

determined adversely to Alaska, would not have a material adverse effect on the financial position or results of operations of the Company.

ITEM 5. Other Information

Alliances with Other Airlines

    In August 2000, due to its merger with Air Canada, Canadian Airlines canceled its marketing alliance with Alaska and Horizon.

Employees

    During the first quarter of 1999, a federal mediator was assigned to assist Horizon and the International Brotherhood of Teamsters in the negotiation of an initial labor contract covering approximately 800 pilots. Negotiations have taken place since then and further negotiations are planned for the fourth quarter of 2000.
