ITEM 2. Management's Discussion and Analysis of Results of Operations and Financial Condition Results of Operations Third Quarter 1999 Compared with Third Quarter 1998 The consolidated net income for the third quarter of 1999 was $54.9 million, or $2.07 per share (diluted), compared with a net income of $45.4 million, or $1.72 per share, in 1998. The 1998 third quarter included an after-tax charge of $10.1 million ($0.38 per diluted share) for a litigation settlement. Consolidated operating income for the third quarter of 1999 was $86.3 million compared to $89.5 million for 1998. Financial and statistical data for Alaska and Horizon is shown on pages 10 and 11. A discussion of this data follows. Alaska Airlines Revenues Capacity remained constant as additional flights in the Arizona and Nevada markets were offset by no service to Russia in 1999 and some reductions in flights in the Alaska markets. Traffic grew by 2.0%, resulting in a 1.3 point increase in passenger load factor. The Canada and Nevada markets experienced the largest increases in load factor. Passenger yields were up 5.1%, with virtually all markets showing an increase over last year. New marketing alliances with other airlines, improved yield management techniques and small fare increases have helped improve yields. The higher load factor combined with the higher yield resulted in a 6.6% increase in revenue per available seat mile (ASM). Consequently, passenger revenues increased 7.2%. Freight and mail revenues decreased 3.5%, due to lower average freight and mail rates. Other-net revenues increased 5.7%, due to increased revenue from travel partners in Alaska's frequent flyer program. Expenses Operating expenses grew by 9.0 % as a result of a 9.0% increase in cost per ASM. The increase in cost per ASM was partly due to higher fuel prices in 1999. Without the higher fuel prices, cost per ASM would have increased 5.9%. Explanations of significant year-over-year changes in the components of operating expenses are as follows: Wages and benefits increased 5.4% due to a 4.5% increase in the number of employees. Employees were added in all areas to service the 4.2% increase in passengers carried. Contracted services increased 16% due to greater use of temporary employees (particularly in computer systems development), higher facility repair costs incurred, higher rates for ground handling services and increased navigation fees in Canada and Mexico. Fuel expense increased 34%, due to a 34% increase in the price of fuel. Maintenance expense increased 21%, exceeding the 2% increase in block hours, due to increased airframe and engine overhaul expense. Commission expense increased 1% on a 7% increase in passenger revenue. As a percentage of passenger revenue, commission expense decreased 5%, from 5.9% to 5.6%. In 1999, 67% of ticket sales were made through travel agents, versus 70% in 1998. Other selling expenses increased 6%, in line with the 7% increase in passenger revenues. Depreciation increased 7%, primarily due to owning six more aircraft in 1999. Landing fees and other rentals increased 15%, higher than the 1% increase in landings, due to rate increases at Seattle, Portland and several other airports. Other expense increased 11%, primarily due to higher expenditures for employee uniforms, recruiting, computer software, operating supplies, utilities and building repairs. Horizon Air Revenues Capacity grew by 17.6%, primarily due to added flights in the Canada, Montana and California markets. Traffic grew by 18.0%, resulting in a 0.3 point increase in passenger load factor. Passenger yields were up 2.1%, with virtually all major markets showing an increase over last year. The higher yield combined with an essentially constant load factor resulted in a 2.1% increase in revenue per available seat mile (ASM). Consequently, passenger revenues increased 20.4%. Expenses Operating expenses grew by 21.7% as a result of an 17.6% increase in capacity and a 3.7% 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 17.4% due to a 19.3% increase in the number of employees. Employees were added in all areas to service the 11% increase in passengers carried. Contracted services increased 28%, higher than the 18% increase in capacity, due to increased navigation fees in Canada, higher ground handling and security charges and greater use of computer and other consultants. Fuel expense increased 57%, due to an 18% increase in fuel consumption combined with a 32% increase in the price of fuel. Maintenance expense increased 38%, greater than the 14% increase in block hours flown, primarily due to higher engine repair costs. Commission expense increased 19% in line with the 20% increase in passenger revenue. Depreciation and amortization expense increased 27%, primarily due to purchase of F-28s in late 1998 and added depreciation on aircraft spare parts and station equipment. Landing fees and other rentals increased 26%, higher than the 18% increase in capacity, primarily due to rent on the new Portland operations center and rate increases at Seattle and Portland airports. Consolidated Nonoperating Income (Expense) The 1998 third quarter included a $16.5 million pretax charge for a litigation settlement. Excluding this charge, net nonoperating items were essentially the same in both periods. Nine Months 1999 Compared with Nine Months 1998 The consolidated net income for the nine months ended September 30, 1999 was $117.2 million, or $4.43 per share (diluted), compared with net income of $97.4 million, or $3.79 per share in 1998. The 1998 results included an after-tax charge of $10.1 million ($0.38 per diluted share) for a litigation settlement. Consolidated operating income for the first nine months of 1999 was $180.2 million compared to $174.6 million for 1998. A discussion of operating results for the two airlines follows. Alaska Airlines Operating income decreased 1.2% to $157.5 million, resulting in a 12.3% operating margin as compared to a 13.4% margin in 1998. Operating revenue per ASM increased 3.5% to 9.80 cents while operating expenses per ASM increased 4.7% to 8.59 cents. The increase in revenue per ASM was due to a 2.5% increase in system passenger yield combined with a 1.0 point increase in load factor. Unit costs increased 4.7% due to higher fuel prices, increased maintenance costs, lower aircraft utilization and higher wages and benefits. Horizon Air Operating income increased 46.0% to $23.5 million, resulting in a 7.5% operating margin as compared to a 6.2% margin in 1998. Operating revenue per ASM decreased 0.9% to 19.29 cents, while operating expenses per ASM decreased 2.2% to 17.85 cents. The decrease in revenue per ASM was due to a 1.6% decrease in system passenger yield combined with a 0.4 point increase in load factor. The impact of higher fuel prices was more than offset by lower unit costs for aircraft rent, maintenance and wages, resulting in a 2.2% decrease in overall unit costs. Consolidated Nonoperating Income (Expense) Net nonoperating items improved $25.7 million over 1998 due to a $16.5 million litigation settlement charge during 1998 and lower interest expense in 1999.

Liquidity and Capital Resources The table below presents the major indicators of financial condition and liquidity. Dec. 31, 1998 Sep. 30, 1999 Change (In millions, except debt-to-equity and per share amounts) Cash and marketable securities $306.6 $246.9 $(59.7) Working capital (deficit) 2.9 (105.2) (108.1) Long-term debt and capital lease obligations 171.5 153.9 (17.6) Shareholders' equity 789.5 913.3 123.8 Book value per common share $ 30.11 $ 34.59 $ 4.48 Debt-to-equity 18%:82% 14%:86% NA Debt-to-equity assuming aircraft operating leases are capitalized at seven times annualized rent 67%:33% 63%:37% NA The Company's cash and marketable securities portfolio decreased by $60 million during the first nine months of 1999. Operating activities provided $324 million of cash during this period. Additional cash was provided by the sale and leaseback of three Dash 8-200 aircraft ($30 million), flight equipment deposits returned ($8 million) and the exercise of stock options ($6 million). Cash was used for $417 million of capital expenditures, including the purchase of five new Boeing 737 aircraft, two formerly leased Boeing 737s, three new Dash 8-200 aircraft, flight equipment deposits and airframe and engine overhauls, and for $18 million of debt repayment. Shareholders' equity increased $124 million due to net income of $117 million and issuance of $6 million of common stock under stock plans. Commitments At September 30, 1999, the Company had firm orders for 65 aircraft requiring aggregate payments of approximately $1.4 billion, as set forth below.

The Company has implemented a project to ensure that the Company's systems will function properly in the year 2000 and thereafter. The Company's Y2K project comprises five phases for each affected system: inventory, assessment, remediation, testing and implementation. Inventory and assessment phases were completed for all systems by first quarter 1999. As of September 30, 1999 the Company has completed every phase, through implementation, of 98% of its mission- critical systems, which is consistent with the industry as a whole as reported by the Air Transport Association (ATA). Remediation, testing and implementation of any remaining systems is scheduled to take place during the fourth quarter of 1999. The Company believes that, with modifications to its existing software and systems and/or conversions to new software, the year 2000 issue will not pose significant operational problems. Most of the Company's information technology projects in the last several years have made the affected systems year 2000 compliant. The direct costs of projects solely intended to correct year 2000 problems are currently estimated at less than $2 million. The Company does not track certain costs attributable to year 2000, such as salaries of information technology staff not dedicated entirely to the project. Additional systems currently under review may require further resources. The Company does not expect any cost increases to have a material effect on its results of operations. The Company is also in contact with its significant suppliers and vendors with which its systems interface and exchange data or upon which its business depends. These efforts are designed to minimize the extent to which its business will be vulnerable to their failure to remediate their own year 2000 issues. The Company has received favorable Y2K readiness responses from all of its mission-critical and 95% of its other high- priority vendors and suppliers, and continues to follow up to ensure readiness predictions are being met. The Company's business is also dependent upon certain governmental organizations or entities such as the Federal Aviation Administration (FAA) that provide essential aviation industry infrastructure. The Company is working with the ATA and the International Air Transport Association (IATA) to monitor the progress of FAA and airports in making their systems year 2000 compliant. In addition, the Company is independently working with certain rural Alaska airports. There can be no assurance that such third parties on which the Company's business relies will successfully remediate their systems on a timely basis. The Company's business, financial condition or results of operations could be materially adversely affected by the failure of its systems or those operated by other parties to operate properly beyond 1999. Areas that could be adversely affected include flight operations, maintenance, planning, reservations, sales, facilities equipment, finance, accounting and the frequent flyer program. The Company already has in place certain disaster contingency plans anticipating the potential loss of essential services such as electricity and financial accounting systems. The Company is building its year 2000 contingency planning on these existing plans. The Company is also developing and executing additional contingency plans designed to allow continued operation in the event of failure of key internal and third party systems or products. This planning involves (a) making a list of critical operations processes, (b) assessing the effect of their failure on safety, operations and financial stability, (c) quantifying the risk of failure of each, and (d) based on the foregoing, developing a discrete contingency plan for each potential failure. Where applicable, the Company will communicate its plans to airports to maximize coordination with their own contingency planning. The Company has completed steps (a) to (c) and expects to complete its contingency planning during the fourth quarter of 1999. The foregoing Year 2000 Computer Issue comments include forward- looking statements regarding the performance of the Company. Actual results may differ materially from these projections. Factors that could cause results to differ include the availability of adequate resources to complete the Company's year 2000 plan, the ability to identify and remediate noncompliant systems, and the success of third parties in remediating their year 2000 issues. PART II. OTHER INFORMATION ITEM 5. Other Information Alliances with Other Airlines Alaska and Horizon have announced a number of new marketing alliances with other airlines that allow reciprocal frequent flyer mileage accrual and redemption privileges and codesharing on certain flights. The purpose of the alliances is to enhance Alaska's and Horizon's revenues by (a) providing our customers more value by offering them more travel destinations and better mileage accrual/redemption opportunities, and (b) gaining access to more connecting traffic from other airlines. The following table shows which of these relationships were existing as of December 31, 1998 and which are new in 1999.

However, Alaska's Mileage Plan members can accrue and redeem miles on this airline's route system. Employees In June 1999, a new 42-month contract covering approximately 1,100 aircraft maintenance technicians, technician helpers, janitors and fleet service employees was ratified. The contract establishes enhanced rates of pay, retirement, health and 401(k) benefits. It also provides for a union shop and, in the event the parties cannot reach agreement on a new contract, requires binding arbitration of certain issues including rates of pay. The contract is amendable December 25, 2002. In October 1999, a new four-year contract covering approximately 2,000 flight attendants was ratified. The contract calls for increases in wage rates, improvements in benefits, work rule changes and scheduling flexibility provisions. The contract is amendable in October, 2003. In October 1999, a new three-year contract covering approximately 3,300 clerical, office and passenger service employees was ratified. The contract calls for increases in wage rates and improvements in benefits, including a matching component to the 401(k) plan. The contract is amendable October 29, 2002. Alaska and the International Association of Machinists (IAM) are continuing negotiation of a new contract (covering approximately 1,000 rampservice and stock clerk employees) with the assistance of a federal mediator. 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 600 pilots. Negotiations have taken place since then and further negotiations are planned for the fourth quarter of 1999. ITEM 6. Exhibits and Reports on Form 8-K (a) Exhibit 27 - Financial data schedule.
