Dec. 31, 2023
Accounting Policies [Abstract] |
Organization and Basis of Accounting, Policy [Policy Text Block] | Organization and Basis of Presentation The consolidated financial statements include the accounts of Alaska Air Group (Air Group, or the Company), and its primary subsidiaries, Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon). Our consolidated financial statements also include McGee Air Services, a ground services subsidiary of Alaska. The Company conducts substantially all of its operations through these subsidiaries. All intercompany balances and transactions have been eliminated. These financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and their preparation requires the use of management’s estimates. Actual results may differ from these estimates. Certain rows, columns, figures, or percentages may not recalculate due to rounding.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents Cash equivalents consist of highly liquid investments with original maturities of three months or less, such as money market funds, commercial paper and certificates of deposit. They are carried at cost, which approximates market value. The Company reduces cash balances when funds are disbursed. Due to the time delay in funds clearing the banks, the Company normally maintains a negative balance in its cash disbursement accounts, which is reported as a current liability. The amount of the negative cash balance was $14 million and $9 million at December 31, 2023 and 2022, and is included in accounts payable, with the change in the balance during the year included in other financing activities in the consolidated statements of cash flows. The Company's restricted cash balances are not material and are classified as Other noncurrent assets. Restricted cash balances are primarily used to guarantee various letters of credit, self-insurance programs, or other contractual rights. They consist of highly liquid securities with original maturities of three months or less. They are carried at cost, which approximates fair value.
Marketable Securities, Policy [Policy Text Block] | Marketable Securities Investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. Investments with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. All cash equivalents and short-term investments are classified as available-for-sale and realized gains and losses are recorded using the specific identification method. Changes in market value are reflected in accumulated other comprehensive income (loss). The Company evaluates the investment portfolio on a quarterly basis for expected credit losses. The Company uses a systematic methodology that groups assets by relevant market sector, and considers available quantitative and qualitative evidence in evaluating potential allowances for credit losses. If the cost of an investment exceeds its fair value, management evaluates, among other factors, general market and industry conditions, credit quality of debt instrument issuers, the duration and extent to which the fair value is less than cost, the Company's intent and ability to hold, or plans to sell, the investment. Once a decline in fair value is determined to be the result of an expected credit loss, an allowance is recorded to Other—net in the consolidated statements of operations.
Inventory, Policy [Policy Text Block] | Inventories and Supplies - net Expendable aircraft parts, materials and supplies are stated at average cost and are included in Inventories and supplies - net. An obsolescence allowance for expendable parts is accrued based on estimated lives of the corresponding fleet type and salvage values. The allowance for expendable inventories was $60 million and $55 million at December 31, 2023 and 2022. Removals from the reserve in 2023 were immaterial. Inventory and supplies - net also includes fuel inventory of $31 million and $38 million at December 31, 2023 and 2022. Repairable and rotable aircraft parts inventories are included in flight equipment.
Property, Plant and Equipment, Policy [Policy Text Block] | Property, Equipment, and Depreciation Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives less an estimated salvage value, which are as follows:
| Estimated Useful Life | Estimated Salvage Value
Aircraft and other flight equipment: |  |
B737 and E175 aircraft | 20 to 25 years | 10%
Buildings | 25 to 40 years | 10%
Minor building and land improvements | 10 years | —%
Capitalized leases and leasehold improvements | Generally shorter of lease term or estimated useful life | —%
Computer hardware and software | 3 to 10 years | —%
Other furniture and equipment | 5 to 10 years | —%
Near the end of an asset's estimated useful life, management updates the salvage value estimates based on current market conditions and expected use of the asset. Repairable and rotable aircraft parts are included in Aircraft and other flight equipment, and are depreciated over the associated fleet life. Capitalized interest, based on the Company’s weighted-average borrowing rate, is added to the cost of the related asset, and is depreciated over the estimated useful life of the asset. The Company evaluates long-lived assets to be held and used for impairment whenever events or changes in circumstances indicate that the total carrying amount of an asset or asset group may not be recoverable. The Company groups assets for purposes of such reviews at the lowest level at which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities, which is generally the fleet level. An impairment loss is considered when estimated future undiscounted cash flows expected to result from the use of the asset or asset group and its eventual disposition are less than its carrying amount. If the asset or asset group is not considered recoverable, a write-down equal to the excess of the carrying amount over the fair value will be recorded. For these purposes, the fair value is estimated using a combination of Level 2 inputs, including published market value estimates for the assets being assessed, and Level 3 inputs, including Company-specific and asset-specific indicators.
Goodwill | Goodwill Goodwill represents the excess of purchase price over the fair value of the related net assets acquired in the Company's acquisition of Virgin America and is not amortized. The total balance of goodwill is associated with the Mainline reporting unit. The Company reviews goodwill for impairment annually in the fourth quarter, or more frequently if events or circumstances indicate that an impairment may exist. The assessment utilizes either a qualitative or quantitative approach. The qualitative approach considers factors such as Alaska Air Group market capitalization and other market trends, and unobservable inputs, including Company specific cash flow and performance information. If it is determined that it is more likely than not that the asset may be impaired, management utilizes a quantitative approach to assess the asset's fair value and the amount of impairment and a charge may be recorded. In 2023, the fair value of the Mainline reporting unit exceeded its carrying value.
Intangible Assets | Intangible Assets Intangible assets are comprised primarily of indefinite-lived airport slots recorded in conjunction with the acquisition of Virgin America. Indefinite-lived intangibles were recorded at fair value upon acquisition and are not amortized, but are tested at least annually for impairment using a similar methodology to goodwill, as described above.
Aircraft Maintenance Deposits | Aircraft Maintenance Deposits Certain Airbus leases include contractually required maintenance deposit payments to the lessor, which collateralize the lessor for future maintenance events should the Company not perform required maintenance. Most of the lease agreements provide that maintenance deposits are reimbursable upon completion of the major maintenance event in an amount equal to the lesser of (i) the amount qualified for reimbursement from maintenance deposits held by the lessor associated with the specific major maintenance event or (ii) the qualifying costs related to the specific major maintenance event. The Company establishes accounting maintenance deposits as assets on the balance sheet using estimates of the anticipated timing and cost of the specific major maintenance events, such that the accounting deposits do not exceed the amount qualified for reimbursement. Aircraft maintenance deposits recorded on the consolidated balance sheets were $70 million and $140 million as of December 31, 2023 and December 31, 2022. As of December 31, 2023, all maintenance deposits are presented within Other current assets on the consolidated balance sheets. Any expense associated with aircraft maintenance deposits which may not ultimately be claimable in the standard course of operating the aircraft is included in Aircraft maintenance in the consolidated statements of operations. Following the Company's decision in early 2022 to exit the Airbus fleet before contractual return timelines, expense associated with aircraft maintenance deposits, including impairment of those deposits which will not be claimed, was recognized ratably over the remaining operating period of the respective aircraft, and classified within Special items - fleet transition and other in the consolidated statement of operations. See Note 2 for further discussion of these special items.
Leased Aircraft Return Costs [Policy Text Block] | Leased Aircraft Return Costs Costs to return leased aircraft are accrued when the costs are probable and reasonably estimable, usually over the twelve months prior to the lease return, unless a determination is made to remove the leased asset from operation. If the leased aircraft is removed from the operating fleet, the estimated cost to return is accrued at the time of removal. If a leased aircraft has a known early retirement date in the future, the estimated cost to return is accrued through the retirement date. Any accrual is based on the time remaining on the lease, planned aircraft usage, and the provisions included in the lease agreement, although the actual amount due to any lessor upon return may not be known with certainty until lease termination. As leased aircraft are returned, payments made reduce the outstanding lease return liability. As of December 31, 2023, the total outstanding liability is $112 million and is included in Other accrued liabilities, compared to $186 million included in Other accrued liabilities and $91 million included in Other liabilities as of December 31, 2022. Expense associated with lease returns in the standard course of operating the aircraft is included in Aircraft maintenance in the consolidated statements of operations. Expense associated with lease returns when aircraft are permanently parked or anticipated to be removed from the fleet before its contractual return date is recorded as a charge at the date the aircraft is permanently parked, regardless of contractual return date, and is classified within Special items - fleet transition and other in the consolidated statements of operations. See Note 2 for further discussion of these special items.
Advertising Cost, Policy, Expensed Advertising Cost [Policy Text Block] | Advertising Expenses The Company's advertising expenses include advertising, sponsorship and promotional costs. Advertising production costs are expensed as incurred. Advertising expense was $78 million, $85 million, and $63 million during the years ended December 31, 2023, 2022 and 2021.
Derivatives, Policy [Policy Text Block] | Derivative Financial Instruments The Company's operations are significantly impacted by changes in aircraft fuel prices and interest rates. In an effort to manage exposure to these risks, the Company has entered into fuel and interest rate derivative instruments. These derivative instruments are recognized at fair value on the balance sheet and changes in the fair value are recognized in AOCL or in the consolidated statements of operations, depending on the nature of the instrument. Cash flows related to these derivative instruments are classified as operating cash flows within the consolidated statements of cash flows. The Company does not apply hedge accounting to its derivative fuel hedge contracts, nor does it hold or issue them for trading purposes. For cash flow hedges related to interest rate swaps, the effective portion of the derivative represents the change in fair value of the hedge that offsets the change in fair value of the hedged item. To the extent the change in the fair value of the hedge does not perfectly offset the change in the fair value of the hedged item, the ineffective portion of the hedge is immediately recognized in interest expense. As of December 31, 2023, the Company has suspended its crude oil hedge program. Our final position will settle in the first quarter of 2025.
Fair Value of Financial Instruments, Policy [Policy Text Block] |
Income Tax, Policy [Policy Text Block] | Income Taxes The Company uses the asset and liability approach for accounting for and reporting income taxes. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities, and their respective tax bases and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance would be established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized. As of December 31, 2023, there is a partial valuation allowance against net deferred tax assets. The Company accounts for unrecognized tax benefits in accordance with the applicable accounting standards. See Note 8 to the consolidated financial statements for more discussion of income taxes.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock-Based Compensation Accounting standards require companies to recognize expense over the service period based on the fair value of stock options and other equity-based compensation issued to employees estimated as of the grant date. These standards apply to all stock awards that the Company grants to employees as well as the Company’s Employee Stock Purchase Plan (ESPP), which features a look-back provision and allows employees to purchase stock at a 15% discount. All stock-based compensation expense is recorded in wages and benefits in the consolidated statements of operations.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), which requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-07. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), which requires public entities to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction on an annual basis. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2023-09.
Receivable | Receivables - net Receivables primarily consist of amounts due from credit card processors for the sale of passenger tickets, from the Company's affinity card partner for the purchase of miles under our loyalty program, and from taxing authorities for certain tax receivables. Given the nature of these receivables, reserves are immaterial to the overall balance. In 2023, certain A321neos were sold to a third-party with full payment for the aircraft occurring in January 2024. The balance owed to Alaska as of December 31, 2023 for these transactions was classified within Receivables - net.
Maintenance Cost, Policy | Airframe and Engine Maintenance Expense Maintenance and repairs on our aircraft, other than engine maintenance on certain engines, are expensed when incurred. Major modifications that extend the life or improve the usefulness of aircraft are capitalized and depreciated over their estimated period of use. Maintenance on B737-800, B737-900ER, and E175 engines are covered under power-by-the-hour agreements with third parties, whereby the Company pays a determinable amount, and transfers risk, to a third party. For these agreements, the Company expenses the contract amounts based on engine usage.
