Loss Per Share

Loss Per Share	6 Months Ended

Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share, which excludes dilution, is computed by dividing net loss available to common shareholders by the weighted average number of common shares outstanding for the period. The potentially dilutive shares that were excluded from the computation of diluted weighted average common stock shares outstanding because their effect would have been antidilutive was 46,344 and 391,510 for the three months ended June 30, 2023 and 2022, respectively, and 71,081 and 439,994 for the six months ended June 30, 2023 and 2022, respectively. Certain warrant shares held by Amazon have not been included in the computation as their performance condition has not yet been satisfied. As of June 30, 2023 and 2022, the unvested Amazon warrant shares excluded from antidilutive shares were 8,183,451 and zero, respectively. Refer to Note 12 to the Notes to Consolidated Financial Statements for additional discussion. The following table shows the computation of basic and diluted loss per share: Three Months Ended June 30, Six months ended June 30, 2023 2022 2023 2022 (in thousands, except for per share data) Numerator: Net Loss $ (12,335) $ (47,374) $ (110,592) $ (180,652) Denominator: Weighted average common stock shares outstanding - Basic 51,587 51,356 51,547 51,322 Weighted average common stock shares outstanding - Diluted 51,587 51,356 51,547 51,322 Net Loss Per Share Basic $ (0.24) $ (0.92) $ (2.15) $ (3.52) Diluted $ (0.24) $ (0.92) $ (2.15) $ (3.52)

Other revenue is primarily derived from the Company's cargo operations and loyalty program. The Company's primary operations are that of its wholly owned subsidiary, Hawaiian. Principally all operations of Hawaiian either originate and/or end in the state of Hawai'i. The management of such operations is based on a system-wide approach due to the interdependence of Hawaiian's route structure in its various markets. As Hawaiian is engaged in only one significant line of business (i.e., air transportation), the Company has concluded that it has only one segment. The Company's operating revenues by geographic region (as defined by the U.S. Department of Transportation (DOT)) are summarized below: Three Months Ended June 30, Six months ended June 30, 2023 2022 2023 2022 Geographic Information (in thousands) Domestic $ 564,684 $ 629,576 $ 1,050,813 $ 1,067,992 Pacific 142,244 62,289 268,718 101,087 Total operating revenue $ 706,928 $ 691,865 $ 1,319,531 $ 1,169,079 Hawaiian attributes operating revenue by geographic region based on the destination of each flight segment. Hawaiian's tangible assets consist primarily of flight equipment, which is mobile across geographic markets, and therefore has not been allocated to specific geographic regions. Other operating revenue consists of cargo revenue, ground handling fees, commissions, and fees earned under certain joint marketing agreements with other companies. These amounts are recognized when the service is provided. Three Months Ended June 30, Six months ended June 30, 2023 2022 2023 2022 Passenger Revenue by Type (in thousands) Passenger revenue, excluding frequent flyer $ 597,558 $ 571,644 $ 1,103,520 $ 943,826 Frequent flyer revenue, transportation component 47,434 45,819 89,998 77,666 Passenger Revenue $ 644,992 $ 617,463 $ 1,193,518 $ 1,021,492 Other revenue (e.g., cargo and other miscellaneous) $ 29,863 $ 45,795 $ 65,001 $ 91,611 Frequent flyer revenue, marketing and brand component 32,073 28,607 61,012 55,976 Other Revenue $ 61,936 $ 74,402 $ 126,013 $ 147,587 As of June 30, 2023 and December 31, 2022, the Company's air traffic liability balance, as it relates to passenger tickets (excluding frequent flyer liability), was $597.3 million and $414.5 million, respectively, which generally represents revenue that is expected to be realized in future periods. During the three months ended June 30, 2023 and 2022, the amount of passenger ticket revenue recognized that was included in air traffic liability as of the beginning of the respective period was $398.4 million and $336.4 million, respectively. During the six months ended June 30, 2023 and 2022, the amount of passenger ticket revenue recognized that was included in air traffic liability as of the beginning of the respective period was $412.2 million and $327.0 million, respectively. Non-refundable tickets sold and credits issued generally expire 13 months from the date of issuance or scheduled flight, as applicable. In April 2020, the Company announced the waiver of certain change fees and extended ticket validity for up to 24 months for (a) tickets issued between March 1, 2020 and December 31, 2020 and (b) tickets issued prior to March 1, 2020 for original travel between March 1, 2020 and February 28, 2021. In December 2021, the Company announced the further extension of ticket validity to December 31, 2022, which also included all Main Cabin and First Class passenger tickets purchased in 2021. The Company records an estimate of breakage revenue on the scheduled flight date for tickets that will expire unused. These estimates are based on the evaluation of actual historical results, available market information, forecasted trends and the extension of the expiration date for certain tickets impacted by the COVID-19 pandemic. At December 31, 2022, $151.9 million of passenger tickets expired unused after receiving extended validity dates throughout the prior two years. During the three months ended June 30, 2023 and 2022, the Company recognized advanced breakage of $17.2 million and $38.2 million, respectively. During the six months ended June 30, 2023 and 2022, the Company recognized advanced breakage of $29.7 million and $56.0 million, respectively. The Company records breakage based on an analysis of certain factors, including unflown rates, rebooking trends, ticket validity terms, and other factors. The Company will continue to monitor customers' travel behavior and may adjust its estimates in the future. Frequent Flyer Accounting The Company's frequent flyer liability is recorded in air traffic liability and noncurrent frequent flyer deferred revenue on its unaudited Consolidated Balance Sheets. The table below presents the Company's frequent flyer liability balance: June 30, 2023 December 31, 2022 (in thousands) Air traffic liability (current portion of frequent flyer revenue) $ 194,029 $ 166,211 Noncurrent frequent flyer deferred revenue 306,046 318,369 Total frequent flyer liability $ 500,075 $ 484,580 The table below presents the Company's activity of the current and noncurrent frequent flyer deferred revenue for the six months ended June 30, 2023 and 2022: 2023 2022 (in thousands) Total frequent flyer liability - beginning balance $ 484,580 $ 466,171 Miles awarded 107,947 92,988 Travel miles redeemed (Passenger Revenue) (89,998) (77,666) Non-travel miles redeemed (Other Revenue) (2,454) (2,251) Total frequent flyer liability - ending balance $ 500,075 $ 479,242

Short-Term Investments [Abstract]
Short-Term Investments	Short-Term Investments The Company's short-term investments that are not classified as cash equivalents are classified as available-for-sale investments and are stated at fair value. Realized gains and losses on sales of investments as well as unrealized gains and losses related to changes in the fair value of equity securities are reflected in Losses on investments, net within Nonoperating income (expense) on the unaudited Consolidated Statements of Operations . The following is a summary of the amortized cost, gross unrealized gains and losses, and fair value of the Company's short-term investments as of June 30, 2023 and December 31, 2022: June 30, 2023 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Debt securities Corporate debt securities $ 298,024 $ 144 $ (17,581) $ 280,587 U.S. government and agency securities 454,146 5 (10,473) 443,678 Other fixed income securities 94,093 6 (7,495) 86,604 Asset-backed securities 29,446 10 (1,801) 27,655 Collateralized loan obligations 43,857 2 (3,288) 40,571 Bank notes 9,944 28 (184) 9,788 Total debt securities 929,510 195 (40,822) 888,883 Derivatives 418 906 (674) 650 Equity securities 218,731 — (25,859) 192,872 Other investments measured at net asset value 1,326 134 — 1,460 Total short-term investments $ 1,149,985 $ 1,235 $ (67,355) $ 1,083,865 December 31, 2022 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (in thousands) Debt securities Corporate debt securities $ 340,493 $ 139 $ (23,009) $ 317,623 U.S. government and agency securities 467,049 181 (12,341) 454,889 Other fixed income securities 110,881 23 (6,499) 104,405 Asset-backed securities 30,205 — (2,039) 28,166 Collateralized loan obligations 43,736 130 (3,684) 40,182 Bank notes 11,493 3 (192) 11,304 Total debt securities 1,003,857 476 (47,764) 956,569 Derivatives 43 1,433 (178) 1,298 Equity securities 213,569 — (26,109) 187,460 Other investments measured at net asset value 2,087 — (221) 1,866 Total short-term investments $ 1,219,556 $ 1,909 $ (74,272) $ 1,147,193 The following tables present fair values and gross unrealized losses by security type and length of time that individual debt securities and other investments measured at net asset value have been in a continuous unrealized loss position: Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses June 30, 2023 (in thousands) Debt securities Corporate debt securities $ 91,886 $ (3,257) $ 179,664 $ (14,324) $ 271,550 $ (17,581) U.S. government and agency securities 282,426 (5,872) 130,711 (4,601) 413,137 (10,473) Other fixed income securities 5,576 (99) 28,085 (7,396) 33,661 (7,495) Asset-backed securities 5,309 (15) 19,121 (1,786) 24,430 (1,801) Collateralized loan obligations — — 34,582 (3,288) 34,582 (3,288) Bank notes 1,461 (116) 1,372 (68) 2,833 (184) Total debt securities $ 386,658 $ (9,359) $ 393,535 $ (31,463) $ 780,193 $ (40,822) $ 386,658 $ (9,359) $ 393,535 $ (31,463) $ 780,193 $ (40,822) Less than 12 Months 12 Months or Greater Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses December 31, 2022 (in thousands) Debt securities Corporate debt securities $ 145,299 $ (10,104) $ 159,216 $ (12,905) $ 304,515 $ (23,009) U.S. government and agency securities 314,790 (8,097) 98,653 (4,244) 413,443 (12,341) Other fixed income securities 17,836 (1,191) 23,316 (5,308) 41,152 (6,499) Asset-backed securities 11,155 (755) 14,435 (1,284) 25,590 (2,039) Collateralized loan obligations 28,133 (2,372) 9,491 (1,312) 37,624 (3,684) Bank notes 2,836 (192) — — 2,836 (192) Total debt securities $ 520,049 $ (22,711) $ 305,111 $ (25,053) $ 825,160 $ (47,764) Other investments measured at net asset value 865 (221) — — 865 (221) $ 520,914 $ (22,932) $ 305,111 $ (25,053) $ 826,025 $ (47,985) As of June 30, 2023 and December 31, 2022, the Company's unrealized losses from debt securities were generated from 507 positions out of 557 positions and 496 positions out of 547 positions, respectively. The Company reviews debt securities quarterly for credit losses and impairment. If the cost of an investment exceeds its fair value, the Company will evaluate, among other factors, general market conditions, credit quality of debt instrument issuers, and the extent to which the fair value is less than cost. This determination requires significant judgment. In making this judgment, the Company employs a systematic methodology that considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. In addition, the Company considers specific adverse conditions related to the financial health of, and business outlook for, the investee. If the Company has plans to sell the security or it is more likely than not that the Company will be required to sell the security before recovery, then a decline in fair value below cost is recorded as an impairment charge in Other, net, within non-operating expense on the unaudited consolidated statements of operations, and a new cost basis in the investment is established. If market, industry, and/or investee conditions deteriorate, the Company may incur future impairments. Debt securities in a continuous unrealized loss position for twelve months or greater as of June 30, 2023 and December 31, 2022 were primarily attributable to changes in interest rates, relative to when the investment securities were purchased. The Company does not intend to sell any of these investments and it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis, which may be at maturity. Accordingly, the Company has determined that the unrealized losses on its debt securities as of June 30, 2023 were temporary in nature. The Company has evaluated these debt securities and did not recognize any significant credit losses as of June 30, 2023 and December 31, 2022. For the three months ended June 30, 2023 and 2022, the unrealized losses on equity securities, recorded in Losses on Investment, net, in Nonoperating income (expense) were $1.5 million and $7.9 million, respectively. For the six months ended June 30, 2023 and 2022, the unrealized losses on equity securities were $0.5 million and $19.4 million, respectively. Contractual maturities of debt securities as of June 30, 2023 are shown below: Under 1 Year 1 to 5 Years Over 5 Years Total (in thousands) Debt Securities Corporate debt $ 249 $ 200,568 $ 79,770 $ 280,587 U.S. government and agency debt 65,833 365,362 12,483 443,678 Other fixed income securities 52,469 20,538 13,597 86,604 Asset-backed securities — 12,472 15,183 27,655 Collateralized loan obligations — — 40,571 40,571 Bank notes 229 5,542 4,017 9,788 Total debt securities $ 118,780 $ 604,482 $ 165,621 $ 888,883 The Company classifies its investments as current assets as these securities are available for use in its current operation.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting Standards Codification (ASC) Topic 820, Fair Value Measurement (ASC 820), defines fair value as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term for the assets or liabilities; and Level 3 — Unobservable inputs for which there is little or no market data and that are significant to the fair value of the assets or liabilities. The tables below present the Company’s financial assets and liabilities measured at fair value on a recurring basis: Fair Value Measurements as of June 30, 2023 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 150,028 $ 149,839 $ 189 $ — Restricted cash 17,860 17,860 — — Short-term investments Debt securities Corporate debt securities 280,587 — 272,444 8,143 U.S. government and agency securities 443,678 — 443,678 — Other fixed income securities 86,604 — 86,604 — Asset-backed securities 27,655 — 18,785 8,870 Collateralized loan obligations 40,571 — 38,143 2,428 Bank notes 9,788 — 1,881 7,907 Total debt securities 888,883 — 861,535 27,348 Derivatives 650 — 650 — Equity securities 192,872 192,137 735 — Other investments measured at net asset value 1,460 — — — Total short-term investments 1,083,865 192,137 862,920 27,348 Other Assets Fuel derivative contracts 2,402 — 2,402 — Assets held-for-sale 2,845 — — 2,845 Total assets measured at fair value $ 1,257,000 $ 359,836 $ 865,511 $ 30,193 Fair Value Measurements as of December 31, 2022 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 46,729 $ 46,535 $ 194 $ — Restricted cash 17,498 17,498 — — Short-term investments Debt securities Corporate debt securities 317,623 — 309,450 8,173 U.S. government and agency securities 454,889 — 454,889 — Other fixed income securities 104,405 — 104,405 — Asset-backed securities 28,166 — 19,133 9,033 Collateralized loan obligations 40,182 — 37,624 2,558 Bank notes 11,304 — 1,878 9,426 Total debt securities 956,569 — 927,379 29,190 Derivatives 1,298 — 1,298 — Equity securities 187,460 186,670 790 — Other investments measured at net asset value 1,866 — — — Total short-term investments 1,147,193 186,670 929,467 29,190 Other Assets Fuel derivative contracts 5,308 — 5,308 — Assets held-for-sale 14,019 — — 14,019 Total assets measured at fair value $ 1,230,747 $ 250,703 $ 934,969 $ 43,209 Cash equivalents and restricted cash. The Company's Level 1 cash equivalents consist of money market securities and mutual funds, which are valued based on quoted prices in an active market. The carrying amounts approximate fair value because of the short-term maturity of these assets. Level 2 cash equivalents consist primarily of debt securities with original maturity dates less than 90 days. The fair value of these instruments is based on a market approach using prices generated by market transactions involving similar assets. Restricted cash includes funds held in a controlled account to be used for debt service payments associated with the Company's loyalty and intellectual brand offering. As of June 30, 2023, approximately $17.9 million was held in the controlled account designated for debt servicing and was classified as restricted cash on the Company's Consolidated Balance Sheets. Short-term investments. The Company's Level 1 short-term investments consist of equity mutual funds, which are valued based on a market approach using prices generated by market transactions involving identical assets. Level 2 short-term investments consist of corporate debt securities, U.S. government and agency securities, other fixed income securities, asset-backed securities, collateralized loan obligations, bank notes, and derivative instruments as further discussed in Note 7, which are valued based on a market approach using industry standard valuation techniques that incorporate inputs such as quoted prices for similar assets, interest rates, benchmark curves, credit ratings, and other observable inputs or market data. Certain asset-backed securities, collateralized loan obligations, and private bank notes that are not readily marketable are classified as Level 3 in the fair value hierarchy and valued using certain unobservable inputs including future cash flows and discount rates. The reconciliation of the Company's short-term investments measured at fair value on a recurring basis using unobservable inputs (Level 3) for the six months ended June 30, 2023 is as follows: Short-term Investment Activity for the six months ended June 30, 2023 Asset-Backed Securities Bank Notes Collateralized Loan Obligations Corporate Debt Securities Total (in thousands) Beginning balance as of December 31, 2022 $ 9,033 $ 9,426 $ 2,558 $ 8,173 $ 29,190 Purchases — 944 — — 944 Sale of investments — (2,189) — — (2,189) Redemptions and paydowns (49) (341) — (12) (402) Amortization and accretion, net 32 2 — 3 37 Realized and unrealized gains (losses), net (146) 65 (130) (21) (232) Ending balance as of June 30, 2023 $ 8,870 $ 7,907 $ 2,428 $ 8,143 $ 27,348 Short-term Investment Activity for the six months ended June 30, 2022 Asset-Backed Securities Bank Notes Collateralized Loan Obligations Corporate Debt Securities Total (in thousands) Beginning balance as of December 31, 2021 $ 4,003 $ 6,753 $ 3,322 $ — $ 14,078 Purchases 2,884 3,440 1,800 5,508 13,632 Sale of investments — — — — — Redemptions and paydowns (31) (350) (2,852) — (3,233) Amortization and accretion, net 79 9 358 — 446 Realized and unrealized gains (losses), net (153) (47) (378) (310) (888) Ending balance as of June 30, 2022 $ 6,782 $ 9,805 $ 2,250 $ 5,198 $ 24,035 Other investments at net asset value (NAV) . In accordance with relevant accounting standards, certain investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in the table above are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position. The investments measured using NAV are investments in a partnership for which a secondary market does not exist. Investments in the partnership are carried at estimated NAV as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. The Company can redeem its shares upon approval by the respective partnerships' managing member. Fuel derivative contracts. The Company uses derivatives to manage risks associated with certain assets and liabilities arising from the potential adverse impact of fluctuations in global fuel prices. 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 derivative financial instruments. Any changes in fair value of these derivative instruments are adjusted through other Nonoperating income (expense) in the period of change. The Company’s fuel derivative contracts consist of crude oil call options, which are not traded on a public exchange. The fair value of these instruments is determined based on inputs available or derived from public markets including contractual terms, market prices, yield curves, and measures of volatility among others. Assets held for sale. The Company's assets held for sale consist of aircraft, engine, rotable and expendable aircraft parts. The assets are measured at the lower of the carrying amount or fair value less cost to sell and a loss is recognized for any initial adjustment of the assets' carrying amount to fair value less cost to sell. The fair value measurements for the Company's held-for-sale assets were based on Level 3 inputs, which include information obtained from third-party valuation sources and other market sources, including recent offers from potential buyers. Refer to Note 11 to the Notes to Consolidated Financial Statements for additional discussion. The table below presents the Company’s debt measured at fair value: Fair Value of Debt June 30, 2023 December 31, 2022 Carrying Fair Value Carrying Fair Value Amount Total Level 1 Level 2 Level 3 Amount Total Level 1 Level 2 Level 3 (in thousands) $ 1,596,756 $ 1,409,934 $ — $ — $ 1,409,934 $ 1,631,725 $ 1,356,561 $ — $ — $ 1,356,561 The fair value estimates of the Company’s debt were based on the discounted amount of future cash flows using the Company’s current incremental rate of borrowing based on quotes of similar debt for other similarly rated companies. The carrying amounts of cash, other receivables, and accounts payable approximate fair value due to the short-term nature of these financial instruments.

Financial Derivative Instruments	Financial Derivative Instruments The Company uses derivatives to manage risks associated with certain assets and liabilities arising from the potential adverse impact of fluctuations in global fuel prices. Fuel Risk Management 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 derivative financial instruments. The Company uses a combination of derivative contracts to hedge its aircraft fuel expense. The following table reflects the amount of realized and unrealized gains and losses recorded as Nonoperating income (expense) in the Consolidated Statements of Operations. Three months ended June 30, Six months ended June 30, Fuel derivative contracts 2023 2022 2023 2022 (in thousands) Losses realized at settlement $ (2,795) $ — $ (4,308) $ — Reversal of prior period unrealized amounts 6,192 — 2,639 — Unrealized losses that will settle in future periods (7,055) — (7,055) — Losses on fuel derivatives recorded as Nonoperating Expense $ (3,658) $ — $ (8,724) $ — Investment Portfolio Management The Company's investment managers use a combination of derivative instruments (swaps, futures, options and forward contracts) to manage risk associated with its investment portfolio, including the volatility in interest rates and currency exchange rates on foreign denominated debt securities. As of June 30, 2023 and December 31, 2022, the Company's derivative positions reflected a net asset position of $0.7 million and $1.3 million within the portfolio. During the three months ended June 30, 2023 and 2022, the Company recognized a net realized and unrealized loss of $1.0 million and a net realized and unrealized gain of $3.3 million, respectively, through Nonoperating income (expense). During the six months ended June 30, 2023 and 2022, the Company recognized a net realized and unrealized loss of $1.0 million and a net realized and unrealized gain of $4.7 million, respectively, through Nonoperating income (expense). The following table presents the gross fair value of asset and liability derivatives, all of which are not designated as hedging instruments under ASC 815, as well as the net derivative positions and location of the asset and liability balances within the Consolidated Balance Sheets.

To manage such credit risks, the Company (1) selects its counterparties based on past experience and credit ratings, (2) limits its exposure to any single counterparty, and (3) periodically monitors the market position and credit rating of each counterparty. Credit risk is deemed to have a minimal impact on the fair value of the derivative instruments as cash collateral would be provided to or by the counterparties based on the current market exposure of the derivative. The Company's agreements with its counterparties also require the posting of cash collateral in the event the aggregate value of the Company's positions exceeds certain exposure thresholds. The aggregate fair value of the Company's derivative instruments that contain credit-risk related contingent features was in a net asset position of $3.1 million and $6.6 million as of June 30, 2023 and December 31, 2022, respectively. ASC 815 requires a reporting entity to elect a policy of whether to offset rights to reclaim cash collateral or obligations to return cash collateral against derivative assets and liabilities executed with the same counterparty under a master netting agreement, or present such amounts on a gross basis. The Company's accounting policy is to present its derivative assets and liabilities on a net basis, including any collateral posted with the counterparty. The Company had $0.4 million collateral posted with its counterparties as of June 30, 2023. No collateral was posted w ith its counterparties as of December 31, 2022. The Company is also subject to market risk in the event these financial instruments become less valuable in the market. However, changes in the fair value of the derivative instruments will generally offset the change in the fair value of the hedged item, limiting the Company's overall exposure.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Commitments As of June 30, 2023, the Company had the following aircraft-related commitments consisting of firm aircraft and engine orders and purchase rights for additional aircraft and engines: Aircraft Type Firm Orders Purchase Rights Expected Delivery Dates A321neo aircraft — 9 N/A Boeing 787-9 aircraft 12 8 Between 2024 and 2027 General Electric GEnx spare engines: Boeing 787-9 spare engines 3 1 Between 2023 and 2027 In July 2018, the Company entered into a purchase agreement for the purchase of 10 Boeing 787-9 "Dreamliner" aircraft, including purchase rights for an additional 10 aircraft with scheduled delivery from 2021 to 2025. In October 2018, the Company entered into a definitive agreement for the selection of GEnx engines to power its Boeing 787-9 fleet. The agreement provides for the purchase of 20 GEnx engines, the right to purchase an additional 20 GEnx engines, and the purchase of up to four spare engines. In December 2022, the Company entered into a supplemental agreement to its Boeing 787-9 purchase agreement, pursuant to which (a) the Company agreed with Boeing to defer the delivery of the Boeing 787-9 aircraft and (b) agreed to exercise purchase options for an additional two Boeing 787-9 aircraft. In July 2023, the Company was notified by Boeing that its 2023 and 2024 Boeing 787-9 aircraft deliveries will be delayed by a couple of months. The Company's first Boeing 787-9 aircraft is now expected to be delivered in January 2024. The committed expenditures under the amended purchase agreement and delivery delay are reflected in the table below. In order to complete the purchase of these aircraft and fund related costs, the Company may need to secure acceptable financing. Financing may be necessary to satisfy the Company's capital commitments for firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to us on acceptable terms when necessary or at all. The Company has commitments with third-parties to provide aircraft maintenance services which include fixed payments based on flight hours for the Company's fleet. The Company also has commitments with third-party service providers for reservations, information technology, and accounting services through 2033. Committed capital and other expenditures include escalation and variable amounts based on estimated forecasts. The gross committed expenditures and committed payments as of June 30, 2023 and for the next five fiscal years and thereafter are detailed below: Aircraft and Aircraft Related Other Total Committed (in thousands) Remaining in 2023 $ 86,036 $ 14,175 $ 100,211 2024 460,310 27,758 488,068 2025 594,533 16,069 610,602 2026 399,226 9,671 408,897 2027 231,771 7,068 238,839 Thereafter — 60,906 60,906 $ 1,771,876 $ 135,647 $ 1,907,523 Litigation and Contingencies The Company is subject to legal proceedings arising in the normal course of its operations. The Company does not anticipate that the disposition of any currently pending proceeding will have a material effect on the Company’s operations, business or financial condition. General Guarantees and Indemnifications In the normal course of business, the Company enters into numerous aircraft financing and real estate leasing arrangements that have various guarantees included in such contracts. It is common in such lease transactions for the lessee to agree to indemnify the lessor and other related third parties for tort liabilities that arise out of, or relate to, the lessee’s use of the leased aircraft or occupancy of the leased premises. In some cases, this indemnity extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by such parties' gross negligence or willful misconduct. Additionally, the lessee typically indemnifies such parties for any environmental liability that arises out of or relates to the lessee's use of the real estate leased premises. The Company believes that it is insured (subject to deductibles) for most of the tort liabilities and related indemnities described above with respect to the aircraft and real estate that it leases. The Company cannot reasonably estimate the potential amount of future payments, if any, under the foregoing indemnities and agreements. Credit Card Holdbacks Under the Company’s bank-issued credit card processing agreements, proceeds from advance ticket sales may be held back to serve as collateral to cover any possible chargebacks or other disputed charges that may occur. As of June 30, 2023 and December 31, 2022, there were no holdbacks held with the Company's credit card processors. In the event of a material adverse change in the Company's business, the credit card processor could increase holdbacks to up to 100% of the amount of outstanding credit card tickets that are unflown (e.g., air traffic liability, excluding frequent flyer deferred revenue), which would result in a restriction of cash. If the Company were unable to obtain a waiver of, or otherwise mitigate the increase in the restriction of cash, it could have a material impact on the Company's operations, business or financial condition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Amazon Agreement	Amazon Agreement On October 20, 2022, Hawaiian and Amazon.com Services LLC (Customer), a wholly owned subsidiary of Amazon.com, Inc. (Amazon), entered into an Air Transportation Services Agreement (the ATSA) under which the Company will provide certain air cargo transportation services to Customer for an initial term of eight years. Thereafter, the Customer may elect to extend the ATSA for two years and, at the end of such period, the parties may mutually agree to extend the term for three additional years The ATSA provides for the Company to initially operate ten A330-300F aircraft for air cargo transportation services, with the Customer having the right to enter into work orders for additional aircraft. The Company will supply flight crews, perform maintenance and certain administrative functions, and procure aircraft insurance. The Customer will pay the Company a fixed monthly fee per aircraft, a per flight hour fee, and a per flight cycle fee for each flight cycle operated. The Customer will also reimburse the Company for certain operating expenses, including fuel, certain maintenance, and insurance premiums. As part of the ATSA, the Company received $11.5 million toward start-up costs which has been recorded in Other liabilities in the Consolidated Balance Sheet. The deferred up-front payment will be amortized into revenue on a pro-rata basis over the term of the contract as revenue is earned. The Company expects operations under the ATSA to commence in the fourth quarter of 2023. The Company and Amazon also entered into a Transaction Agreement, under which the Company agreed to issue to Amazon.com NV Investment Holdings LLC, a wholly owned subsidiary of Amazon, a warrant (the Warrant) to acquire up to 9,442,443 shares (the Warrant Shares), of the Company's common stock, par value $0.01 per share. The exercise price with respect to the first 6,294,962 Warrant Shares that vest will be $14.71 per share (the First Tranche). The exercise price with respect to the remaining 3,147,481 Warrant Shares (the Second Tranche) will be determined based on the 30-day volume-weighted average price of the Company’s common stock as of the earlier of (i) October 20, 2025, or (ii) the date that the entire First Tranche is vested. At execution of the ATSA, 1,258,992 Warrant Shares, valued at $11.6 million, vested, and were recorded in Other assets in the Consolidated Balance Sheet. The remaining Warrant Shares will vest based on qualifying payments to be made by Amazon or its affiliates either under the ATSA or generally to the Company with respect to air cargo or air charter services (the Performance Condition), excluding commercial passenger service, up to $1.8 billion of qualifying payments in the aggregate. The Warrant was valued in two tranches, both utilizing a Monte Carlo Simulation Model. The First Tranche, which met the grant date criteria under ASC 718 at execution of the ATSA, has a set exercise price and a grant date fair value of approximately $57.9 million, or $9.19 per Warrant Share. The Warrant is classified as an equity award, subject only to the Performance Condition referenced above which impacts the timing of the vesting of the Warrant Shares. For the Second Tranche, which will not have an established exercise price until a future date, as noted above, was valued at approximately $18.5 million, or $5.89 per Warrant Share as of June 30, 2023. As a grant date has not yet been established, the Company will estimate the fair value of these Warrant Shares on a quarterly basis; however, the Company also considered that until the Warrant Shares vest, there is no financial statement impact related to the Second Tranche for unvested shares under ASC 718. At their grant date, the Company will value these Warrant Shares, which will be classified as equity awards, subject to the Performance Condition. As discussed above, 1,258,992 Warrant Shares (included in the First Tranche), with a value of $11.6 million, vested at execution of the ATSA, and were recorded as Other assets on the Consolidated Balance Sheet. The $11.6 million will be recognized as contra-revenue pro rata with estimated revenue earned over the term of the ATSA. For the remaining Warrant Shares, the value of the Warrant Shares, at grant date, will be recognized as a reduction of the transaction price of the Company’s flight services performance obligation over the term of the ATSA as revenue is earned with an offsetting entry to Capital in excess of par.
