Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation Hawaiian Holdings, Inc. (the Company, Holdings, we, us and our) and its direct wholly-owned subsidiary, Hawaiian Airlines, Inc. (Hawaiian), are incorporated in the State of Delaware. The Company's primary asset is its sole ownership of all issued and outstanding shares of common stock of Hawaiian. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including its principal subsidiary, Hawaiian, through which the Company conducts substantially all of its operations. All significant inter-company balances and transactions have been eliminated upon consolidation. The Company reclassified certain prior period amounts to conform to current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Cash Equivalents Cash equivalents consist of short-term, highly liquid investments with an original maturity of three months or less at the date of purchase. Short Term Investments Investments with original maturities greater than three months and remaining maturities 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 short-term investments, which consists of debt securities, are classified as available-for-sale, and realized gains and losses are recorded using the specific identification method. Changes in market value, excluding other-than-temporary impairments, are reflected in accumulated other comprehensive income (loss). Spare Parts and Supplies Spare parts and supplies are valued at average cost, and primarily consist of expendable parts for flight equipment and other supplies. An allowance for obsolescence of expendable parts is provided over the estimated useful lives of the related aircraft and engines for spare parts expected to be on hand at the date the aircraft are retired from service. These allowances are based on management's estimates and are subject to change. Property, Equipment and Depreciation Property and equipment are stated at cost and depreciated on a straight-line basis to their estimated residual values over the asset's estimated useful life. Depreciation begins when the asset is placed into service. Aircraft and related parts begin depreciating on the aircraft's first revenue flight. The following table summarizes our property and equipment: 2019 2018 (in thousands) Flight equipment $ 2,622,504 $ 2,307,033 Pre-delivery deposits on flight equipment 90,788 119,957 Other property and equipment 366,024 421,582 3,079,316 2,848,572 Less accumulated depreciation and amortization (762,544 ) (663,461 ) Total property and equipment, net 2,316,772 2,185,111 Estimated useful lives and residual values of property and equipment are as follows: Boeing 717-200 aircraft and engines 15-16 years, 5 - 34% residual value Airbus A330-200 aircraft and engines 25 years, 10% residual value Airbus A321neo aircraft and engines 25 years, 10% residual value ATR turboprop aircraft and engines 10 years, 15% residual value Flight and ground equipment under finance lease Shorter of lease term or useful life Major rotable parts Average lease term or useful life for related aircraft, 10% - 15% residual value Improvements to leased flight equipment and the cargo maintenance hangar Shorter of lease term or useful life Facility leasehold improvements Shorter of lease term, including assumed lease renewals when renewal is economically compelled at key airports, or useful life Furniture, fixtures and other equipment 3 - 7 years, no residual value Capitalized software 3 - 7 years, no residual value In January 2019, the Company completed the exit and retirement of its Boeing 767-300 aircraft fleet. In 2019, the Company changed its accounting estimate for the expected useful life of its Boeing 717-200 aircraft from a range of 7 to 11 years to 15 to 16 years . The change in estimate was applied prospectively effective October 1, 2019 and does not have a material impact on current and/or future reporting periods. Additions and modifications that significantly enhance the operating performance and/or extend the useful lives of property and equipment are capitalized and depreciated over the lesser of the remaining useful life of the asset or the remaining lease term, as applicable. Expenditures that do not improve or extend asset lives are charged to expense as incurred. Pre-delivery deposits are capitalized when paid. Aircraft under finance leases are recorded at an amount equal to the present value of minimum lease payments utilizing the Company's incremental borrowing rate at lease inception and amortized on a straight-line basis over the lesser of the remaining useful life of the aircraft or the lease term. The amortization is recorded in depreciation and amortization expense on the Consolidated Statement of Operations. Accumulated amortization of aircraft and other finance leases was $103.7 million and $90.5 million as of December 31, 2019 and 2018 , respectively. The Company capitalizes certain costs related to the acquisition and development of computer software and amortizes these costs using the straight-line method over the estimated useful life of the software. The net book value of computer software, which is included in Other property and equipment on the consolidated balance sheets, was $33.9 million and $27.9 million at December 31, 2019 and 2018 , respectively. The value of construction in progress, primarily consisting of aircraft in 2019 and 2018 , which is included in property and equipment on the consolidated balance sheets, was $26.5 million and $47.3 million as of December 31, 2019 and 2018 , respectively. Amortization expense related to computer software was $17.5 million , $14.6 million and $12.3 million for the years ended December 31, 2019 , 2018 , and 2017 respectively. Aircraft Maintenance and Repair Costs Maintenance and repair costs for owned and leased flight equipment, including the overhaul of aircraft components, are charged to operating expenses as incurred. Engine overhaul costs covered by power-by-the-hour arrangements are paid and expensed as incurred or expensed on a straight-line basis and are based on the amount of hours flown per contract. Under the terms of these power-by-the-hour agreements, the Company pays a set dollar amount per engine hour flown on a monthly basis and the third-party vendor assumes the obligation to repair the engines at no additional cost, subject to certain specified exclusions. As of December 31, 2019 and 2018 , the Company had approximately $100.7 million and $95.0 million , respectively in prepayments to one of its power-by-the-hour vendors, which is recoverable over the next three years . Additionally, although the Company's aircraft lease agreements specifically provide that it is responsible for maintenance of the leased aircraft, the Company pays maintenance reserves to the aircraft lessors that are applied toward the cost of future maintenance events. These reserves are calculated based on a performance measure, such as flight hours, and are available for reimbursement to the Company upon the completion of the maintenance of the leased aircraft. However, reimbursements are limited to the available reserves associated with the specific maintenance activity for which the Company requests reimbursement. Under certain aircraft lease agreements, the lessor is entitled to retain excess amounts on deposit at the expiration of the lease, if any; whereas at the expiration of certain other existing aircraft lease agreements any such excess amounts are returned to the Company, provided that it has fulfilled all of its obligations under the lease agreements. The maintenance reserves paid under the lease agreements do not transfer either the obligation to maintain the aircraft or the cost risk associated with the maintenance activities to the aircraft lessor. In addition, the Company maintains the right to select any third-party maintenance provider. Maintenance reserve payments that are expected to be recovered from lessors are recorded as deposits in the Consolidated Balance Sheets as an asset until it is less than probable that any portion of the deposit is recoverable. In addition, payments of maintenance reserves that are not substantially and contractually related to the maintenance of the leased assets are accounted for as lease payments. In order to properly account for the costs that are related to the maintenance of the leased asset, the Company bifurcates its maintenance reserves between deposits and lease payments. Goodwill and Indefinite-lived Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized. We apply a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. We assess the value of our goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Goodwill. When the Company evaluates goodwill for impairment using a quantitative approach, it estimates the fair value of the reporting unit by considering the market capitalization. If the reporting unit's fair value exceeds its carrying value, no further testing is required. If, however, the reporting unit's carrying value exceeds its fair value, the Company then determines the amount of the impairment charge, if any. The Company recognizes an impairment charge if the carrying value of the reporting unit's goodwill exceeds its estimated fair value. Intangible Assets. The Company assesses its indefinite-lived assets under a qualitative approach. The Company analyzes market factors to determine if events and circumstances have affected the fair value of the indefinite-lived intangible assets. If the Company determines that it is more likely than not that the asset value may be impaired, it then uses the quantitative approach to assess the asset's fair value and the amount of the impairment. The Company performs the quantitative impairment test for indefinite-lived intangible assets by comparing the asset's fair value to its carrying value. Impairment of Long-Lived Assets and Finite-lived Intangible Assets Long-lived assets used in operations, consisting principally of property and equipment and finite-lived intangible assets, are tested for impairment when events or changes in circumstances indicate, in management's judgment, that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amount. When testing for impairment management considers market trends, the expected useful lives of the assets, changes in economic conditions, recent transactions involving sales of similar assets and, if necessary, estimates of future undiscounted cash flows. To determine whether impairment exists for aircraft used in operations, assets are grouped at the fleet-type level (the lowest level for which there are identifiable cash flows) and future cash flows are estimated based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If, at any time, management determines the net carrying value of an asset is not recoverable, the amount is reduced to its fair value during the period in which such determination is made. Any changes in the estimated useful lives of these assets will be accounted for prospectively. Revenue Recognition We record passenger ticket sales and tickets sold by other airlines for use on Hawaiian as passenger revenue when the transportation is provided or upon scheduled flight for tickets expected to expire unused. Passenger revenue associated with unused tickets, which represent unexercised passenger rights, is recognized in proportion to the pattern of rights exercised by related passengers (e.g. scheduled departure dates). To calculate the portion to be recognized as revenue in the period, the Company utilizes historical information and applies the trend rate to the current air traffic liability balances for that specific period. Ticket change fees are recorded in air traffic liability and recognized when the related transportation is provided. Certain governmental taxes are imposed on the Company's ticket sales through a fee included in ticket prices. The Company collects these fees and remits them to the appropriate government agency. Management has elected (via a practical expedient election) to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer, e.g., sales, use, value added, and certain excise taxes. These fees have been presented on a net basis in the accompanying Consolidated Statements of Operations and recorded as a liability until remitted. Frequent Flyer Program HawaiianMiles, Hawaiian's frequent flyer travel award program, provides a variety of awards to program members based on accumulated mileage. ASC 606 requires the Company to account for miles earned by passengers in the HawaiianMiles program through flight activity as a component of the passenger revenue ticket transaction at the estimated selling price of the miles. Ticket consideration received is allocated between the performance obligations, primarily travel and miles earned by passengers. The allocated value of the miles is deferred until the free travel is used by the passenger, at which time it is included in revenue. The value of the ticket used in the determination of the estimated selling price is based on the historical value of equivalent flights to those provided for loyalty awards and the related miles redeemed to obtain that award adjusted for breakage or fulfillment. The equivalent ticket value (ETV) includes a fulfillment discount (breakage) to reflect the value of the award ticket over the number of miles that, based on historical experience, will be needed to obtain the award. Our estimate of ETV takes into consideration quantitative and qualitative factors, such as program changes and fares of similar tickets, and consideration of cabin class and geographic region. The Company also sells mileage credits to companies participating in our frequent flyer program. These contracts generally include multiple performance obligations, including the transportation that will ultimately be provided when the mileage credits are redeemed and marketing and brand related activities. The marketing and brand performance obligations are effectively provided each time a HawaiianMiles members uses the co-branded credit card and monthly access to customers lists and marketing is provided, which corresponds to the timing of when the Company issues or is obligated to issue the mileage credits to the HawaiianMiles member. Therefore, the Company recognize revenue for the marketing and brand performance obligation when HawaiianMiles members use their co-brand credit card and the resulting mileage credits are issued to them, which best correlates with our performance in satisfying the obligation. In 2018, the Company amended its partnership with Barclaycard US, Hawaiian's co-branded credit card partner. Management determined that the amendment should be accounted for as a termination of the existing contract and the creation of a new contract under ASC 606 and the relative selling price was determined for each performance obligation of the new agreement. The new agreement continues through 2024 and includes improved economics and enhanced product offerings for our Barclay's co-branded cardholders. The amended agreement did not change, and includes the following performance obligations; (i) transportation that will ultimately be provided when mileage credits are redeemed (transportation), (ii) the Hawaiian Airlines brand and access to its members lists (collectively, brand performance), (iii) marketing, and (iv) airline benefits to cardholders, including discounts and anniversary travel benefits, baggage waivers and inflight purchase credits. The Company determined the relative fair value of each performance obligation by estimating the selling prices of the deliverables by considering discounted cash flows using multiple inputs and assumptions, including: (1) the expected number of miles to be awarded and redeemed; (2) the estimated weighted average equivalent ticket value, adjusted by a fulfillment discount; (3) the estimated total annual cardholder spend; (4) an estimated royalty rate for the Hawaiian portfolio; and (5) the expected use of each of the airline benefits. The overall consideration received is allocated to the performance obligations based on their relative selling prices. Accounting for frequent flyer revenue involves the use of various techniques to estimate revenue. To determine the total estimated transaction price, the Company forecasts future credit card activity based on historical data. The relative selling price is determined using management’s estimated standalone selling price of each performance obligation. The objective of using the estimated selling price based methodology is to determine the price at which the Company would transact a sale if the product or service were sold on a standalone basis. Accordingly, the Company determines our best estimate of selling price by considering multiple inputs and methods including, but not limited to, discounted cash flows, brand value, number of miles awarded and number of miles redeemed. The Company estimates the selling price of miles using an ETV adjusted for a fulfillment discount as described above. Miles expire after 18 months of member account inactivity. The Company reviews its breakage estimates, which impacts ETV and loyalty recognition patterns, annually based upon the latest available information regarding redemption and expiration patterns (e.g., credit card and non-credit card holders). The Company's estimate of the expected expiration of miles requires significant management judgment. Current and future changes to expiration assumptions or to the expiration policy, or to program rules and program could affect the estimated value of a mile. Accounts Receivable Accounts receivable primarily consist of amounts due from credit card companies, non-airline partners, and cargo transportation customers. The Company provides an allowance for uncollectible accounts equal to the estimated losses expected to be incurred based on historical chargebacks, write-offs, bankruptcies and other specific analyses. Bad debt expense was not material in any period presented. Costs to obtain or fulfill a contract In order for the Company to provide transportation to its customers, the Company incurs fulfillment costs (booking fees, credit card fees, and commission/selling costs), which are deferred until the period in which the flight occurs. As of December 31, 2019 and 2018 , the Company's asset balance associated with these costs were $15.7 million and $16.3 million , respectively. During the twelve months ended December 31, 2019 , 2018 , and 2017 , expenses related to these costs totaled to $91.0 million , $96.0 million , and $95.5 million , respectively. To determine the amount to capitalize and expense at the end of each period, the Company uses historical sales data and estimates the amount associated with unflown tickets. Pension and Postretirement and Postemployment Benefits The Company accounts for its defined benefit pension and other postretirement and postemployment plans in accordance with ASC 715, Compensation—Retirement Benefits (ASC 715), which requires companies to measure their plans' assets and obligations to determine the funded status at fiscal year-end, reflect the funded status in the statement of financial position as an asset or liability, and recognize changes in the funded status of the plans in comprehensive income during the year in which the changes occur. Pension and other postretirement and postemployment benefit expenses are recognized on an accrual basis over each employee's service periods. Pension expense is generally independent of funding decisions or requirements. The Company uses the corridor approach in the valuation of its defined benefit pension and other postretirement and postemployment plans. The corridor approach defers all actuarial gains and losses resulting from variances between actual results and actuarial assumptions. These unrecognized actuarial gains and losses are amortized when the net gains and losses exceed 10% of the greater of the market-related value of plan assets or the projected benefit obligation at the beginning of the year. The amount in excess of the corridor is amortized over the expected average remaining service period of active plan participants for the open plans and is amortized over the expected average remaining lifetime of inactive participants for plans whose population is “all or almost all” inactive. Advertising Costs Advertising costs are expensed when incurred. Advertising expense was $22.3 million , $19.3 million and $16.6 million for the years ended December 31, 2019 , 2018 , and 2017 , respectively. Capitalized Interest Interest is capitalized upon the payment of predelivery deposits for aircraft and engines, and is depreciated over the estimated useful life of the asset from service inception date. Share-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair value of the awards are estimated using the following: (1) option-pricing models for grants of stock options or (2) fair value at the measurement date (usually the grant date) for awards of stock subject to service and / or performance-based vesting. The resulting cost is recognized as compensation expense over the period of time during which an employee is required to provide services to the Company (the service period) in exchange for the award, the service period generally being the vesting period of the award. The Company's policy is to recognize forfeitures as they occur. 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 aircraft fuel prices, interest rates and foreign currency exchange rates. The following table summarizes the accounting treatment of the Company's derivative contracts: Derivative Type Accounting Designation Classification of Realized Gains and Losses Classification of Unrealized Gains (Losses) Foreign currency exchange contracts Designated as cash flow hedges Passenger revenue AOCI Fuel hedge contracts Not designated as hedges Gains (losses) on fuel derivatives Change in fair value is recorded in nonoperating income (expense) Foreign currency exchange contracts Not designated as hedges Nonoperating income (expense), Other Change in fair value is recorded in nonoperating income (expense) If the Company terminates a derivative designated for hedge accounting under ASC 815, prior to its contractual settlement date, then the cumulative gain or loss recognized in AOCI at the termination date remains in AOCI until the forecasted transaction occurs. In a situation where it becomes probable that a hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. All cash flows associated with purchasing and settling derivatives are classified as operating cash flows in the Consolidated Statements of Cash Flows. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (ASU 2016-02), which was subsequently codified within ASC 842, Leases . ASC 842 requires a lessee to recognize a right-of-use asset and a lease liability in the statement of financial position for all leases (with the exception of short-term leases) at the lease commencement date and recognize expenses similar to the current ASC 840, Leases. ASC 842 is effective for fiscal years, and interim periods beginning after December 15, 2018. The Company adopted ASC 842 as of January 1, 2019 using the transition method that provides for a cumulative-effect adjustment to retained earnings upon adoption. The Company elected the package of transition provisions available for expired or existing contracts, which allows the Company to carry-forward our historical assessments of (a) whether contracts are, or contain, leases, (b) lease classification, and (c) initial direct costs. The adoption of the ASC 842 had a significant impact on the Company's consolidated balance sheet due to the recognition of approximately $603.9 million of operating lease liabilities and ROU assets for operating leases of $649.3 million . Additionally, the Company recognized a $4.9 million (net of tax of $1.6 million ) cumulative effect adjustment credit to retained earnings. The adjustment to retained earnings was driven principally by ASC 842's elimination of the previous build-to-suit lease accounting guidance under ASC 840, and resulted in the derecognition of build-to-suit assets and liabilities that remained on the balance sheet after the end of the construction period. ASC 842 then required the application of lease accounting to the agreement, which resulted in an operating lease. This resulted in the recognition of a ROU asset, inclusive of building costs incurred by the Company to place the asset into service, of $124.7 million , and a lease liability of $90.8 million . The Consolidated Financial Statements as of and for the twelve months ended December 31, 2019 are presented under the new standard, while comparative periods presented are not adjusted and continue to be reported in accordance with our historical accounting policy. See Note 10 for additional information. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12), which better aligns a company's risk management activities and financial reporting for hedging relationships and is intended to simplify hedge accounting requirements. ASU 2017-12 was effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted this standard during the first quarter of 2019. The adoption of this standard did not have an impact on the Company's Consolidated Financial Statements. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (ASU 2016-13), which requires the use of an "expected loss" model on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU 2016-13 replaces the incurred loss methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company will adopt ASU 2016-13 effective January 1, 2020. The Company does not expect that the adoption of the standard will have a significant impact on its consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share, which excludes dilution, is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material. The following table shows our computation of basic and diluted earnings per share: Year Ended December 31, 2019 2018 2017 (in thousands, except for per share data) Numerator: Net Income $ 223,984 $ 233,200 $ 330,610 Denominator: Weighted average common shares outstanding—Basic 47,435 50,338 53,074 Assumed exercise of stock options and awards 111 150 339 Weighted average common shares outstanding—Diluted 47,546 50,488 53,413 Net Income Per Common Stock Share: Basic $ 4.72 $ 4.63 $ 6.23 Diluted $ 4.71 $ 4.62 $ 6.19

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Passenger & Other revenue - The Company’s contracts with customers have two principal performance obligations, which are the promise to provide transportation to the passenger and the frequent flyer miles earned on the flight. In addition, the Company often charges additional fees for items such as baggage and other miscellaneous ancillary services. Such items are not capable of being distinct from the transportation provided because the customer can only benefit from the services during the flight. The transportation performance obligation, including the redemption of HawaiianMiles awards for flights, is satisfied, and revenue is recognized, as transportation is provided. In some instances, tickets sold by the Company can include a flight segment on another carrier which is referred to as an interline segment. In this situation, the Company acts as an agent for the other carrier and revenue is recognized net of cost in other revenue. Tickets sold by other airlines where the Company provides the transportation are recognized as passenger revenue at the estimated value to be billed to the other airline when travel is provided. Differences between amounts billed and the actual amounts may be rejected and rebilled or written off if the amount recorded was different from the original estimate. The majority of the Company's revenue is derived from transporting passengers on our aircraft. 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 offers only one significant line of business (i.e., air transportation), management has concluded that it has only one segment. The Company's operating revenues by geographic region (as defined by the Department of Transportation, DOT) are summarized below: Year Ended December 31, 2019 2018 2017 (in thousands) Domestic $ 2,057,650 $ 2,071,861 $ 1,976,971 Pacific 774,578 765,550 698,174 Total operating revenue $ 2,832,228 $ 2,837,411 $ 2,675,145 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 are mobile across geographic markets, and, therefore, have not been allocated to specific geographic regions. Domestic revenue includes the company's North America and Interisland operations. During the years ended December 31, 2019, 2018, and 2017, North America routes accounted for approximately 74% , 71% and 71% of domestic revenue, respectively. 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. Year Ended December 31, 2019 2018 2017 Passenger Revenue by Type (in thousands) Passenger revenue, excluding frequent flyer $ 2,440,909 $ 2,454,811 $ 2,351,062 Frequent flyer revenue, transportation component 156,863 147,982 135,765 Passenger Revenue $ 2,597,772 $ 2,602,793 $ 2,486,827 Other revenue (e.g. cargo and other miscellaneous) $ 147,237 $ 163,140 $ 142,172 Frequent flyer revenue, marketing and brand component 87,219 71,478 46,146 Other Revenue $ 234,456 $ 234,618 $ 188,318 For the twelve months ended December 31, 2019 , 2018 , and 2017 , the Company's total revenue was $2.8 billion , $2.8 billion , and $2.7 billion , respectively. As of December 31, 2019 and 2018 , the Company's Air traffic liability balance as it relates to passenger tickets (excluding frequent flyer) was $425.1 million and $427.8 million , respectively, which represents future revenue that is expected to be realized over the next 12 months . During the twelve months ended December 31, 2019 , 2018 , and 2017 , the amount of revenue recognized that was included in Air traffic liability as of the beginning of the respective period was $424.2 million , $421.0 million , and $363.9 million , respectively. Frequent Flyer Revenue. The Company's frequent flyer liability is recorded in Air traffic liability (short-term) and Noncurrent frequent flyer deferred revenue in the Company's consolidated balance sheet based on estimated and expected redemption patterns using historical data and analysis. As of December 31, 2019 and 2018 , the balances were as follows: As of December 31, 2019 2018 (in thousands) Air traffic liability (current portion of frequent flyer deferred revenue) $ 174,588 $ 168,570 Noncurrent frequent flyer deferred revenue 175,218 163,619 Total frequent flyer liability $ 349,806 $ 332,189

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements 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 in which there is little or no market data and that are significant to the fair value of the assets or liabilities. The following tables present information about the Company's financial assets and liabilities measured at fair value on a recurring basis: Fair Value Measurements as of December 31, 2019 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 216,491 $ 205,943 $ 10,548 $ — Short-term investments Corporate debt 100,713 — 100,713 — U.S. government and agency securities 75,481 — 75,481 — Other fixed income securities 69,405 — 69,405 — Total short-term investments 245,599 — 245,599 — Fuel derivative contracts 5,878 — 5,878 — Foreign currency derivatives 4,424 — 4,424 — Total assets measured at fair value $ 472,392 $ 205,943 $ 266,449 $ — Foreign currency derivatives 593 — 593 — Total liabilities measured at fair value $ 593 $ — $ 593 $ — Fair Value Measurements as of December 31, 2018 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 121,154 $ 42,175 $ 78,979 $ — Short-term investments Corporate debt 142,102 — 142,102 — U.S. government and agency securities 37,107 — 37,107 — Municipal bonds 9,871 — 9,871 — Other fixed income securities 43,161 — 43,161 — Total short-term investments 232,241 — 232,241 — Fuel derivative contracts 1,572 — 1,572 — Foreign currency derivatives 4,579 — 4,579 — Total assets measured at fair value $ 359,546 $ 42,175 $ 317,371 $ — Foreign currency derivatives 1,347 — 1,347 — Total liabilities measured at fair value $ 1,347 $ — $ 1,347 $ — Cash equivalents. The Company’s Level 1 cash equivalents consist of money market securities. The carrying amounts approximate fair value because of the short-term maturity of these assets. Level 2 cash equivalents consist primarily of debt securities. The fair value of these instruments is based on a market approach using prices generated by market transactions involving identical or comparable assets. Short-term investments. Short-term investments 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. Fuel derivative contracts. Fuel derivative contracts, which are not traded on a public exchange, are valued based on inputs available or derived from public markets including contractual terms, market prices, yield curves, fuel price curves and measures of volatility, among others. Foreign currency derivatives. Foreign currency derivatives are valued based primarily on data readily observable in public markets. The table below presents the Company's debt measured at fair value: Fair Value of Debt December 31, 2019 December 31, 2018 Carrying Fair Value Carrying Fair Value Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 (in thousands) (in thousands) $ 610,397 $ 605,286 $ — $ — $ 605,286 $ 467,760 $ 461,805 $ — $ — $ 461,805 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 for similar obligations. The carrying amounts of cash, other receivables, and accounts payable approximate fair value due to the short-term nature of these financial instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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, interest rates and foreign currencies. 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. As of December 31, 2019 , the Company's portfolio comprised of crude oil call options, which were not designated as hedges under ASC Topic 815, Derivatives and Hedging (ASC 815), for hedge accounting treatment. As a result, any changes in fair value of these derivative instruments are adjusted through other nonoperating income (expense) in the period of change. The following table reflects the amount of realized and unrealized gains and losses recorded as nonoperating income (expense) in the Consolidated Statements of Operations. Year Ended December 31, 2019 2018 2017 (in thousands) Gains (losses) realized at settlement $ (12,403 ) $ 25,563 $ (534 ) Prior period unrealized amounts 8,181 (11,792 ) (7,946 ) Unrealized gains (losses) that will settle in future periods (2,487 ) (8,181 ) 11,792 Gains (losses) on fuel derivatives recorded as nonoperating income (expense) $ (6,709 ) $ 5,590 $ 3,312 Foreign Currency Exchange Rate Risk Management The Company is subject to foreign currency exchange rate risk due to revenues and expenses denominated in foreign currencies, with the primary exposures being the Japanese Yen and Australian Dollar. To manage exchange rate risk, the Company executes its international revenue and expense transactions in the same foreign currency to the extent practicable. The Company enters into foreign currency forward contracts to further manage the effects of fluctuating exchange rates. The gain or loss is reported as a component of AOCI and reclassified into earnings in the same period in which the related sales are recognized as passenger revenue. The Company believes that its foreign currency forward contracts will continue to be effective in offsetting changes in cash flow attributable to the hedged risk. The Company expects to reclassify a net gain of approximately $3.8 million into earnings over the next 12 months from AOCI based on the values at December 31, 2019 . The following tables present the gross fair value of asset and liability derivatives that are designated as hedging instruments under ASC 815 and derivatives that 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 that are in a net asset position was $9.7 million and $4.8 million as of December 31, 2019 and December 31, 2018 , 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 no collateral posted with its counterparties as of December 31, 2019 and December 31, 2018 . 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.

Boeing 717-200 Aircraft In June 2019, the Company made scheduled balloon payment of $44.8 million to pay off its debt facility for the financing of Boeing 717-200 aircraft originally purchased in 2010. As of December 31, 2019 , all owned Boeing 717-200 aircraft were unencumbered. Enhanced Equipment Trust Certificates (EETC) In 2013, Hawaiian consummated an EETC financing, whereby it created two pass-through trusts, each of which issued pass-through certificates. The proceeds of the issuance of the pass-through certificates were used to purchase equipment notes issued by the Company to fund a portion of the purchase price for six Airbus aircraft, all of which were delivered in 2013 and 2014. The equipment notes are secured by a lien on the aircraft, and the payment obligations of Hawaiian under the equipment notes will be fully and unconditionally guaranteed by the Company. The Company issued the equipment notes to the trusts as aircraft were delivered to Hawaiian. Hawaiian received all proceeds from the pass-through trusts by 2014 and recorded the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The Company evaluated whether the pass-through trusts formed are variable interest entities ("VIEs") required to be consolidated by the Company under applicable accounting guidance, and determined that the pass-through trusts are VIEs. The Company determined that it does not have a variable interest in the pass-through trusts. Neither the Company nor Hawaiian invested in or obtained a financial interest in the pass-through trusts. Rather, Hawaiian has an obligation to make interest and principal payments on the equipment notes held by the pass-through trusts, which are fully and unconditionally guaranteed by the Company. Neither the Company nor Hawaiian intends to have any voting or non-voting equity interest in the pass-through trusts or to absorb variability from the pass-through trusts. Based on this analysis, the Company determined that it is not required to consolidate the pass-through trusts. Foreign Denominated Financing In 2019, the Company entered into two Japanese Yen denominated agreements totaling $227.9 million ( ¥24.7 billion ), which were collateralized through a combination of two A321neo and four A330-200 aircraft with a net book value of approximately $382.7 million . The terms of the loans are 12 years and 5.5 years , at fixed installment coupon rates of 0.76% and 0.65% , respectively. In 2018, the Company entered into two Japanese Yen denominated financings with a total value of approximately $86.5 million ( ¥9.6 billion ), collateralized by the aircraft financed with a net book value of $106.1 million . Each financing is for a term of 12 years with quarterly or semiannual principal and interest payments, respectively, at fixed installment coupon rates of 1.01% and 1.05% , respectively. At each balance sheet date, the Company remeasures the outstanding principal balance at the spot rate for the respective period and records any gain or loss at the current rate within the other nonoperating income (expense) line item in the Consolidated Statements of Operations. During 2019 and 2018 , the Company recorded foreign currency unrealized losses of $0.5 million and $0.4 million, respectively. Revolving Credit Facility In 2018, Hawaiian amended and restated the existing credit agreement with Citigroup Global Markets Inc., increasing the secured revolving credit and letter (Revolving Credit Facility) from $225 million to $235 million . This Revolving Credit Facility will mature in December 2022 and has a 12 -month renewal option. This was accounted for as a modification of the existing agreement and approximately $0.6 million in unamortized costs will be amortized over the amended term along with additional issuance costs for the renewal of $2.0 million . Hawaiian may, from time to time, grant liens on certain eligible account receivables, aircraft, spare engines, ground support equipment and route authorities, as well as cash and certain cash equivalents, in order to secure its outstanding obligations under the Revolving Credit Facility. Indebtedness under the Revolving Credit Facility will bear interest, at a per annum rate based on, at Hawaiian's option: (1) a variable rate equal to the London interbank offer rate plus a margin of 2.0% ; or (2) Alternate base rate (as defined in the Revolving Credit Facility) plus a margin of 1.0% . Hawaiian is also subject to compliance and liquidity covenants under the Revolving Credit Facility. As of December 31, 2019 , the Company had no outstanding borrowing under the Revolving Credit Facility. Schedule of Maturities of Long-Term Debt As of December 31, 2019 , the scheduled maturities of long-term debt are as follows (in thousands): 2020 $ 55,444 2021 82,576 2022 89,854 2023 54,835 2024 52,732 Thereafter 274,956 $ 610,397

Leases [Abstract]
Leases	Leases As discussed in Note 1 , the Company adopted ASC 842 as of January 1, 2019, using the modified retrospective approach. Prior year financial statements were not recast under the new standard and, therefore, those amounts are not presented below. The Company leases aircraft, engines, airport terminal facilities, maintenance hangars, commercial real estate, and other property and equipment, among other items. The Company combines lease and nonlease components in calculating the ROU asset and lease liabilities for the aforementioned asset groups. Certain leases include escalation clauses, renewal options, and/or termination options. When lease renewals or termination options are considered to be reasonably certain, such periods are included in the lease term and fixed payments are included in the calculation of the lease liability and ROU asset. The Company's leases do not provide a readily determinable implicit rate; therefore, the Company utilizes an incremental borrowing rate to discount lease payments based on information available at lease commencement. The Company gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates. Aircraft and Engines As of December 31, 2019 , the Company leased 19 of its 68 aircraft. Of the 19 lease contracts, 4 aircraft lease contracts were accounted for as finance leases, with the remaining 15 lease contracts accounted for as operating leases. These aircraft leases have remaining lease terms ranging from 2 years to 11 years . The Company also had 5 engines under operating leases with remaining lease terms ranging from less than 1 year to 7 years. Aircraft and engine finance leases continue to be reported on our consolidated balance sheet, while operating leases were added to the balance sheet with the adoption of the new standard. Airport Terminal Facilities The Company's facility leases are primarily for terminal space at airports that it serves, most notably, its operations in the State of Hawai'i. These leases are classified as operating leases and reflect the Company's use of airport terminals, office space, cargo and maintenance facilities. The Company leases space from government agencies that control the use of the airport. The remaining lease terms vary from 1 month to 30 years. At the majority of U.S. airports, the lease rates depend on airport operating costs or the use of the facilities and are reset at least annually. Because of the variable nature of the rates, these leases are not recorded on our balance sheet as a ROU asset and lease liability. Other Commercial Real Estate The Company leases non-airport facility office space supporting its operations, including its headquarters in Honolulu, Hawai'i. These leases are classified as operating and have remaining lease terms ranging between 1 to 7 years. Maintenance Hangar In November 2016, the Company entered into a lease agreement with the Department of Transportation of the State of Hawai'i (the "Hawai'i Lease") to lease a cargo and maintenance hangar at the Daniel K. Inouye International Airport with a remaining lease term of 32 years as of December 31, 2019 . As the hangar was not fully constructed, the Company took responsibility of the construction and was responsible for the remainder of the construction costs of $37.3 million . In accordance with the applicable accounting guidance, specifically as it relates to the Company's involvement in the construction of the hangar, the Company was considered the owner of the asset under construction and previously recognized an additional $73.0 million asset, with a corresponding finance liability, for the amount previously spent by the lessor. As discussed in Note 1, ASC 842 eliminated the previous build-to-suit lease accounting guidance and resulted in the derecognition of build-to-suit assets and liabilities that remained on the balance sheet after the end of the construction period. ASC 842 then required the application of lease accounting to the agreement. The agreement is accounted for as an operating lease under ASC 842. In July 2019, the Company entered into an amendment to the Hawai'i Lease with the State of Hawai'i. The amendment resulted in the adjustment of lease rates and was accounted for as a modification under ASC 842. The modification did not result in a change in lease classification. The impact to both the ROU asset and lease liability is reflected in the Lease Position Table below. Other Property and Equipment The Company leases certain IT assets (including data center access, equipment, etc.) and various other non-aircraft equipment. The remaining lease terms range from 1 to 3 years. Certain lease IT assets are embedded within service agreements. The combined lease and nonlease components of those agreements are included in the ROU asset and lease liability. Lease Position as of December 31, 2019 The table below presents the lease-related assets and liabilities recorded on the consolidated balance sheet. Classification on the Balance Sheet December 31, 2019 (in thousands) Assets: Operating lease assets Operating lease right-of use assets $ 632,545 Finance lease assets Property and equipment, net 153,102 Total lease assets $ 785,647 Liabilities: Current Operating Current maturities of operating leases $ 83,224 Finance Current maturities of finance lease obligations 21,857 Noncurrent Operating Noncurrent operating leases 514,685 Finance Finance lease obligations 141,861 Total lease liabilities $ 761,627 Weighted-average remaining lease term Operating leases 10.7 years Finance leases 8.6 years Weighted-average discount rate Operating leases (1) 4.67 % Finance leases 4.45 % (1) Upon adoption of the new lease standard, discount rates used for existing leases were established at January 1, 2019.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Act was enacted into law, which significantly changed existing U.S. tax law and reduced the U.S. federal corporate tax from 35% to 21%. The Company recognized a one-time benefit of $83.0 million during the year ended December 31, 2017 from the impact of the revaluation of deferred tax assets and liabilities. During the year ended December 31, 2018, the Company completed its accounting for the effects of the Tax Act and recorded an additional tax benefit of $9.3 million primarily related to deductions for additional pension contributions made in 2018 for the 2017 Plan year. The significant components of income tax expense are as follows: Years Ended December 31, 2019 2018 2017 (in thousands) Current Federal $ (46,764 ) $ 23,438 $ 49,835 State 3,708 9,087 11,471 $ (43,056 ) $ 32,525 $ 61,306 Deferred Federal $ 109,489 $ 29,782 $ (7,017 ) State 14,579 5,651 5,922 $ 124,068 $ 35,433 $ (1,095 ) Income tax expense $ 81,012 $ 67,958 $ 60,211 As of December 31, 2019, the tax benefit of $46.8 million was primarily driven by federal bonus depreciation rules of the Tax Act, which were further clarified by final and proposed regulations issued during 2019. The income tax expense differed from amounts computed at the statutory federal income tax rate as follows: Years Ended December 31, 2019 2018 2017 (in thousands) Income tax expense computed at the statutory federal rate $ 64,049 $ 63,243 $ 136,788 Increase (decrease) resulting from: State income taxes, net of federal tax effect 14,446 11,643 11,095 Nondeductible meals 756 797 1,146 Tax Cuts and Jobs Act impact — (9,333 ) (82,978 ) Excess tax benefits from stock issuance — (188 ) (5,288 ) Other 1,761 1,796 (552 ) Income tax expense $ 81,012 $ 67,958 $ 60,211 The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including the reversal of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. The Company assesses the realizability of its deferred tax assets and records a valuation allowance when it is more likely than not, that a portion, or all, of the deferred tax assets will not be realized. The components of the Company's deferred tax assets and liabilities were as follows: December 31, 2019 2018 (in thousands) Deferred tax assets: Accumulated pension and other postretirement benefits $ 51,416 $ 45,663 Operating leases liabilities 147,929 — Finance leases 2,909 3,515 Air traffic liability and frequent flyer liability 57,240 70,206 Partnership deferred revenue 9,086 9,697 Federal and state net operating loss carryforwards 11,540 2,547 Accrued compensation 16,430 15,843 Other accrued assets 12,609 11,758 Other assets 10,124 16,421 Total gross deferred tax assets 319,283 175,650 Less: Valuation allowance (2,547 ) (2,547 ) Net deferred tax assets $ 316,736 $ 173,103 Deferred tax liabilities: Intangible assets $ (3,216 ) $ (3,297 ) Property and equipment, principally accelerated depreciation (433,395 ) (324,614 ) Operating lease right-of-use assets (159,601 ) — Other liabilities (10,088 ) (12,962 ) Total deferred tax liabilities (606,300 ) (340,873 ) Net deferred tax liability $ (289,564 ) $ (167,770 ) As of December 31, 2019 and 2018 , the Company had federal and state net operating loss carryforwards of $42.4 million and $1.1 million , respectively. The Tax Act changed the federal rules governing net operating loss carryforwards. For net operating loss carryforwards arising from tax years beginning after December 31, 2017, the Tax Act limits a taxpayer's ability to utilize such carryforwards to 80% of taxable income. In addition, net operating loss carryforwards arising in tax years ending after December 31, 2017 can be carried forward indefinitely, but carryback is generally prohibited. The Company’s federal net operating losses have indefinite carryover period and state net operating losses will begin to expire in 2033, if not utilized. Utilization of our net operating loss carryforwards may be subject to annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions. Our net operating loss carryforwards could expire before utilization if subject to annual limitations. In accordance with ASC 740, the Company reviews its uncertain tax positions on an ongoing basis. The Company may be required to adjust its liability as these matters are finalized, which could increase or decrease its income tax expense and effective income tax rates or result in an adjustment to the valuation allowance. The Company records the uncertain tax position liability in Other accrued liabilities in the consolidated balance sheet as it expects that the majority of unrecognized tax benefits will be resolved within the next 12 months. The table below reconciles beginning and ending amounts of unrecognized tax benefits related to uncertain tax positions: 2019 2018 2017 (in thousands) Balance at January 1 $ 5,086 $ 4,081 $ 3,329 Increases related to prior year tax positions 118 336 253 Increases related to current year tax positions 1,059 669 499 Balance at December 31 $ 6,263 $ 5,086 $ 4,081 The Company's policy is to recognize interest and penalties related to unrecognized tax benefits within the provision for income taxes. In 2019 , 2018 , and 2017 , the Company recognized expense of $0.9 million , $0.0 million , and $0.0 million , respectively, for interest and penalties on uncertain tax positions. As of December 31, 2019 and 2018 , the Company accrued approximately $0.9 million and $0.0 million , respectively, for the payment of interest and penalties related to uncertain tax positions. The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company's federal and state income tax returns for tax years 2016 and beyond remain subject to examination by the Internal Revenue Service and state taxing authorities.

Contract Termination Expense and Special Items	Contract Terminations Expense and Special Items Contract terminations expense and special items in the statements of consolidated operations consisted of the following: Year Ended December 31, 2019 2018 2017 (in thousands) Operating Contract terminations expense (1) $ — $ 35,322 $ — Operating special items: Loss on sale of aircraft (3) — — 4,771 Collective bargaining agreement (4) — — 18,679 Total Contract terminations expense and Operating special items $ — $ 35,322 $ 23,450 Nonoperating Other nonoperating special items: Partial settlement and curtailment loss (2) $ — $ — $ 10,384 Loss on plan termination (2) — — 35,201 Total Other nonoperating special items $ — $ — $ 45,585 Contract terminations expense (1) During the twelve months ended December 31, 2018, the Company terminated two contracts which incurred a total of $35.3 million in contract terminations expense. The transactions are described below: In February 2018, the Company exercised its right to terminate the aircraft purchase agreement between the Company and Airbus for six Airbus A330-800neo aircraft and the purchase rights for an additional six Airbus A330-800neo aircraft. To terminate the purchase agreement, the Company was obligated to repay Airbus for concessions received relating to a prior firm order, training credits, as well as forfeit the pre-delivery progress payments made towards the flight equipment. The Company recorded a contract terminations expense to reflect a portion of the termination penalty within the Consolidated Statements of Operations. In January 2018, the Company entered into a transaction with its lessor to early terminate and purchase three Boeing 767-300 aircraft leases and concurrently entered into a forward sale agreement for the same three Boeing 767-300 aircraft, including two Pratt & Whitney 4060 engines for each aircraft. These aircraft were previously accounted for as operating leases. In order to exit the lease and purchase the aircraft, the Company agreed to pay a total of $67.1 million (net of all deposits) of which a portion was expensed immediately and recognized as a contract termination fee. The expensed amount represents the total purchase price amount over fair value of the aircraft purchased as of the date of the transaction. Special items (2) In August 2017, the Company terminated the Hawaiian Airlines, Inc. Salaried & IAM Merged Pension Plan (the Merged Plan) and settled a portion of its pilots' other post-retirement medical plan liability. In connection with the reduction of these liabilities, the Company recorded one-time Other nonoperating special charges of $35.2 million related to the Merged Plan termination and $10.4 million related to the other post-retirement (OPEB) medical plan partial settlement. (3) In April 2017, the Company executed a sale leaseback transaction with an independent third party for three Boeing 767-300 aircraft. The lease terms for the three aircraft commenced in April 2017 and end between November 2018 through January 2019. During the twelve months ended December 31, 2017, the Company recorded a loss on sale of aircraft of $4.8 million . (4) In February 2017, the Company reached a tentative agreement with Air Line Pilots Association (ALPA), covering the Company's pilots. In March 2017, the Company received notice from ALPA that the agreement was ratified by ALPA's members. The agreement became effective April 1, 2017 and has a term of 63 months. The agreement includes, among other various benefits, a pay adjustment and ratification bonus computed based on previous service. During the twelve months ended December 31, 2017, the Company expensed $18.7 million principally related to a one-time payment to reduce the Company's future 401K employer contribution for certain pilot groups, which is not recoverable once paid.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans Defined Benefit Plans Hawaiian sponsors a defined benefit pension plan covering the ALPA and prior to August 2017, sponsored the defined benefit pension plans for the International Association of Machinists and Aerospace Workers (AFL-CIO) (IAM) and other personnel (salaried, Transport Workers Union, Network Engineering Group). The plans for the IAM and other employees were frozen in September 1993. Effective January 1, 2008, benefit accruals for pilots under age 50 as of July 1, 2005 were frozen (with the exception of certain pilots who were both age 50 and older and participants of the plan on July 1, 2005) and Hawaiian began making contributions to an alternate defined contribution retirement program for its pilots. All of the pilots' accrued benefits under their defined benefit plan at the date of the freeze were preserved. In addition, Hawaiian sponsors four unfunded defined benefit postretirement medical and life insurance plans and a separate plan to administer the pilots' disability benefits. In 2016, the Hawaiian Airlines, Inc. Pension Plan for Salaried Employees (Salaried Plan) was consolidated into the Hawaiian Airlines, Inc. Pension Plan for Employees Represented by the International Association of Machinists (IAM), which established the the Merged Plan. At that time, the net liabilities of the Salaried Plan were transferred to the Merged Plan. In August 2017, the Company completed the termination of the plan by transferring the assets and liabilities to a third-party insurance company. In 2017, the Company contributed a total of $18.5 million in cash to fully fund the plan and recognized a one-time financial loss of $35.2 million as an Other nonoperating special item on the Company's Consolidated Statement of Operations. The Company no longer has any expected contributions to the Merged Plan due to the final settlement. In March 2017, the Company announced the ratification of a 63 -month contract amendment with its pilots as represented by the ALPA. In connection with the ratification of the agreement, the parties agreed to eliminate the post-65 post-retirement medical benefit for all active pilots, and replace the benefit with a heath retirement account (HRA) managed by ALPA, which represented a curtailment and partial settlement of the pilots' other post-retirement benefit plan. In August 2017, the Company made a one-time cash payment of $101.9 million to fund the HRA and settle the post-65 post-retirement medical plan obligation (for active pilots as of April 1, 2017). The cash contributed was distributed to the trust funding the individual health retirement notional accounts of the participants. In connection with the settlement of the liability, the discount rate was updated to 3.86% . The Company recognized a one-time settlement loss of $10.4 million . The obligation recorded for the unsettled portion of this plan was $73.4 million as of the partial settlement date. The following tables summarize changes to projected benefit obligations, plan assets, funded status and applicable amounts included in the Consolidated Balance Sheets: 2019 2018 Pension Other Pension Other (in thousands) Change in projected benefit obligations Benefit obligations, beginning of year $ (398,087 ) $ (122,648 ) $ (426,066 ) $ (120,417 ) Service cost (175 ) (8,255 ) (352 ) (8,119 ) Interest cost (16,910 ) (5,472 ) (15,599 ) (4,708 ) Actuarial gains (losses) (52,208 ) (16,113 ) 22,677 6,007 Benefits paid 22,484 5,250 21,253 4,639 Less: federal subsidy on benefits paid N/A (48 ) N/A (50 ) Benefit obligation at end of year (a) $ (444,896 ) $ (147,286 ) $ (398,087 ) $ (122,648 ) Change in plan assets Fair value of assets, beginning of year $ 308,024 $ 26,363 $ 296,386 $ 26,078 Actual return on plan assets 65,820 4,532 (17,339 ) (1,697 ) Employer contribution 461 6,900 50,230 6,621 Benefits paid (22,484 ) (5,250 ) (21,253 ) (4,639 ) Fair value of assets at end of year $ 351,821 $ 32,545 $ 308,024 $ 26,363 Unfunded status at December 31 $ (93,075 ) $ (114,741 ) $ (90,063 ) $ (96,285 ) Amounts recognized in the statement of financial position consist of: Current benefit liability $ (667 ) $ (3,553 ) $ (386 ) $ (3,342 ) Noncurrent benefit liability (92,408 ) (111,188 ) (89,677 ) (92,943 ) $ (93,075 ) $ (114,741 ) $ (90,063 ) $ (96,285 ) Amounts recognized in accumulated other comprehensive loss Unamortized actuarial loss (gain) $ 127,367 $ (1,662 ) $ 124,560 $ (15,606 ) Prior service cost (credit) — 1,512 — 1,737 $ 127,367 $ (150 ) $ 124,560 $ (13,869 ) _______________________________________________________________________________ (a) The accumulated pension benefit obligation as of December 31, 2019 and 2018 was $444.9 million and $397.5 million , respectively.

Negotiated salary increases and expected changes in fleet and seat positions on the aircraft are included in the assumed rate of compensation increase, which ranged from 2.0% to 7.3% in both 2019 and 2018 ). ** Expected return on plan assets used to determine the net periodic benefit expense for 2020 is 6.76% for Pension and 4.90% for Disability. A change in the assumed health care cost trend rates would have the following effects: 100 Basis 100 Basis (in thousands) Effect on postretirement benefit obligation at December 31, 2019 $ 9,961 $ (8,525 ) Effect on total service and interest cost for the year ended December 31, 2019 874 (732 ) Estimated amounts that will be amortized from accumulated other comprehensive income into net periodic benefit cost in 2020 are as follows: Pension Other (in thousands) Actuarial (gain) loss $ 4,073 $ (385 ) Amortization of prior service cost — 225 To be recognized in net periodic benefit cost from accumulated other comprehensive (gain) loss $ 4,073 $ (160 ) Plan Assets The Company develops the expected long-term rate of return assumption based on historical experience and by evaluating input from the trustee managing the plan's assets, including the trustee's review of asset class return expectations by several consultants and economists, as well as long-term inflation assumptions. The Company's expected long-term rate of return on plan assets is based on a target allocation of assets, which is based on the goal of earning the highest rate of return while maintaining risk at acceptable levels. The Retirement Plan for Pilots of Hawaiian Airlines, Inc. and the Pilot's Voluntary Employee Beneficiary Association Disability and Survivor's Benefit Plan (VEBA) strive to have assets sufficiently diversified so that adverse or unexpected results from any one security class will not have an unduly detrimental impact on the entire portfolio. Prior to termination, the Merged Plan targeted to have its assets align with the potential liability as of the expected settlement date. The actual allocation of the Company's pension and disability plan assets and the target allocation of assets by category at December 31, 2019 are as follows: Asset Allocation for Pilots pension and VEBA Plans 2019 Target Equity securities 60 % 60 % Fixed income securities 35 % 35 % Real estate investment trusts 5 % 5 % 100 % 100 % The table below presents the fair value of the Company's pension plan and other postretirement plan investments (excluding cash and receivables): Fair Value Measurements as of December 31, 2019 2018 (in thousands) Pension Plan Assets: Equity index funds $ 214,319 $ 175,583 Fixed income funds 118,321 110,650 Real estate investment fund 16,778 14,718 Insurance company pooled separate account 2,407 7,076 Total $ 351,825 $ 308,027 Postretirement Assets: Common collective trust fund $ 32,366 $ 26,217 The fair value of the investments in the table above have been estimated using the net asset value per share, and in accordance with subtopic ASC 820-10, Fair Value Measurement and Disclosures , are not required to be presented in the fair value hierarchy. Equity index funds. The investment objective of these funds are to obtain a reasonable rate of return while investing principally or entirely in foreign or domestic equity securities. There are currently no redemption restrictions on these investments. Fixed income funds. The investment objective of these funds are to obtain a reasonable rate of return while principally investing in foreign and domestic bonds, mortgage-backed securities, and asset-backed securities. There are currently no redemption restrictions on these investments. Real estate investment fund. The investment objective of this fund is to obtain a reasonable rate of return while principally investing in real estate investment trusts. There are currently no redemption restrictions on these investments. Insurance Company Pooled Separate Account. The investment objective of the Insurance Company Pooled Separate Account is to invest in short-term cash equivalent securities to provide a high current income consistent with the preservation of principal and liquidity. Common collective trust (CCT). The postretirement plan's CCT investment consists of a balanced profile fund and a conservative profile fund. These funds primarily invest in mutual funds and exchange-traded funds. The balanced profile fund is designed for participating trusts that seek substantial capital growth, place modest emphasis on short-term stability, have long-term investment objectives, and accept short-term volatility in the value of the fund's portfolio. The conservative profile fund is designed for participating trusts that place modest emphasis on capital growth, place moderate emphasis on short-term stability, have intermediate-to-long-term investment objectives, and accept moderate short-term volatility in the value of the fund's portfolio. There are currently no redemption restrictions on these investments. Based on current legislation and assumptions, the Company expects to have a minimum contribution requirement of $17.8 million for 2020 . The Company projects that Hawaiian's pension plans and other postretirement benefit plans will make the following benefit payments, which reflect expected future service, during the years ending December 31: Other Benefits Pension Gross Expected (in thousands) 2020 $ 24,498 $ 5,852 $ — 2021 25,492 6,436 — 2022 26,098 7,093 — 2023 26,644 7,816 — 2024 26,948 8,513 — 2025 - 2029 134,719 50,811 — $ 264,399 $ 86,521 $ — Defined Contribution Plans The Company also sponsors separate defined contribution plans for its pilots, flight attendants and ground, and salaried personnel. Contributions to the Company's defined contribution plans were $46.7 million , $42.0 million and $39.1 million for the years ended December 31, 2019 , 2018 and 2017 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Commitments The Company has commitments with a third-party to provide aircraft maintenance services which include fixed payments as well as variable payments based on flight hours for the Company's Airbus fleet through 2027. The Company also has commitments with third-party service providers for reservations, IT, and accounting services through 2024. Committed capital and other expenditures include escalation and variable amounts based on estimated forecasts. The gross committed expenditures for upcoming aircraft deliveries and other commitments for the next five years and thereafter are detailed below: Aircraft and aircraft related Other Total Committed (in thousands) 2020 $ 177,643 $ 83,130 $ 260,773 2021 312,335 82,839 395,174 2022 433,245 72,738 505,983 2023 243,805 65,036 308,841 2024 350,408 57,335 407,743 Thereafter 110,175 131,267 241,442 $ 1,627,611 $ 492,345 $ 2,119,956 As of December 31, 2019 , the Company had the following capital commitments consisting of firm aircraft and engine orders and purchase rights: Aircraft Type Firm Purchase Expected Delivery Dates A321neo aircraft 1 9 In 2020 B787-9 aircraft 10 10 Between 2021 and 2025 Pratt & Whitney spare engines: A321neo spare engines — 2 N/A General Electric GEnx spare engines: B787-9 spare engines 2 2 Between 2021 and 2025 In February 2018, the Company exercised its right to terminate its aircraft purchase agreement between the Company and Airbus for six Airbus A330-800neo aircraft and the purchase rights for an additional six Airbus A330-800neo aircraft. Refer to Note 12 for discussion on the contract termination charge. In July 2018, the Company entered into a purchase agreement for the purchase of ten Boeing 787-9 "Dreamliner" aircraft with 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 2018, the Company entered into an amendment to the purchase agreement with Boeing, which includes an option for the Company to accelerate delivery of Boeing 787-9 aircraft from 2024 and 2025 to 2023; however, the Company does not currently expect to execute the option to accelerate its planned delivery schedule. The committed expenditures under these agreements are reflected in the table above. The Company also intends to enter into additional related agreements in connection with the Boeing 787-9 purchases, including for the purchase of spare parts and materials and related services. In order to complete the purchase of these aircraft and fund related costs, the Company may need to secure acceptable financing. The Company has backstop financing available from aircraft and engine manufacturers, subject to certain customary conditions. Financing may be necessary to satisfy our 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. Litigation and Contingencies The Company is subject to legal proceedings arising in the normal course of its operations. Management 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 the contract. 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 their gross negligence or willful misconduct. Additionally, the lessee typically indemnifies such parties for any environmental liability that arises out of or relates to its use of the real estate leased premises. The Company believes that it is insured (subject to deductibles) for most tort liabilities and related indemnities described above with respect to the aircraft and real estate that it leases. The Company cannot estimate the potential amount of future payments, if any, under the foregoing indemnities and agreements. Credit Card Holdback Under the Company's bank-issued credit card processing agreements, certain 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 December 31, 2019 and 2018 , there were no holdbacks held with the Company's credit card processors. In the event of a material adverse change in the business, the holdback could increase to an amount up to 100% of the applicable credit card air traffic liability, which would also cause an increase in the level of restricted cash. Labor Negotiations As of December 31, 2019 , approximately 83% of employees were represented by unions. Additionally, the collective bargaining agreement for the AFA, which represents 29% of employees became amendable on January 1, 2017, the Company is currently in negotiations with the AFA. The Company can provide no assurance that a successful or timely resolution of these labor negotiations will be achieved.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Hawaiian Holdings, Inc. (the Company, Holdings, we, us and our) and its direct wholly-owned subsidiary, Hawaiian Airlines, Inc. (Hawaiian), are incorporated in the State of Delaware. The Company's primary asset is its sole ownership of all issued and outstanding shares of common stock of Hawaiian. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including its principal subsidiary, Hawaiian, through which the Company conducts substantially all of its operations. All significant inter-company balances and transactions have been eliminated upon consolidation.
Reclassifications	The Company reclassified certain prior period amounts to conform to current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.
Cash Equivalents	Cash Equivalents Cash equivalents consist of short-term, highly liquid investments with an original maturity of three months or less at the date of purchase.
Short Term Investments	Short Term Investments Investments with original maturities greater than three months and remaining maturities 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 short-term investments, which consists of debt securities, are classified as available-for-sale, and realized gains and losses are recorded using the specific identification method. Changes in market value, excluding other-than-temporary impairments, are reflected in accumulated other comprehensive income (loss).
Spare Parts and Supplies	Spare Parts and Supplies Spare parts and supplies are valued at average cost, and primarily consist of expendable parts for flight equipment and other supplies. An allowance for obsolescence of expendable parts is provided over the estimated useful lives of the related aircraft and engines for spare parts expected to be on hand at the date the aircraft are retired from service. These allowances are based on management's estimates and are subject to change.
Property, Equipment and Depreciation	Property, Equipment and Depreciation Property and equipment are stated at cost and depreciated on a straight-line basis to their estimated residual values over the asset's estimated useful life. Depreciation begins when the asset is placed into service. Aircraft and related parts begin depreciating on the aircraft's first revenue flight. The following table summarizes our property and equipment: 2019 2018 (in thousands) Flight equipment $ 2,622,504 $ 2,307,033 Pre-delivery deposits on flight equipment 90,788 119,957 Other property and equipment 366,024 421,582 3,079,316 2,848,572 Less accumulated depreciation and amortization (762,544 ) (663,461 ) Total property and equipment, net 2,316,772 2,185,111 Estimated useful lives and residual values of property and equipment are as follows: Boeing 717-200 aircraft and engines 15-16 years, 5 - 34% residual value Airbus A330-200 aircraft and engines 25 years, 10% residual value Airbus A321neo aircraft and engines 25 years, 10% residual value ATR turboprop aircraft and engines 10 years, 15% residual value Flight and ground equipment under finance lease Shorter of lease term or useful life Major rotable parts Average lease term or useful life for related aircraft, 10% - 15% residual value Improvements to leased flight equipment and the cargo maintenance hangar Shorter of lease term or useful life Facility leasehold improvements Shorter of lease term, including assumed lease renewals when renewal is economically compelled at key airports, or useful life Furniture, fixtures and other equipment 3 - 7 years, no residual value Capitalized software 3 - 7 years, no residual value In January 2019, the Company completed the exit and retirement of its Boeing 767-300 aircraft fleet. In 2019, the Company changed its accounting estimate for the expected useful life of its Boeing 717-200 aircraft from a range of 7 to 11 years to 15 to 16 years . The change in estimate was applied prospectively effective October 1, 2019 and does not have a material impact on current and/or future reporting periods. Additions and modifications that significantly enhance the operating performance and/or extend the useful lives of property and equipment are capitalized and depreciated over the lesser of the remaining useful life of the asset or the remaining lease term, as applicable. Expenditures that do not improve or extend asset lives are charged to expense as incurred. Pre-delivery deposits are capitalized when paid. Aircraft under finance leases are recorded at an amount equal to the present value of minimum lease payments utilizing the Company's incremental borrowing rate at lease inception and amortized on a straight-line basis over the lesser of the remaining useful life of the aircraft or the lease term. The amortization is recorded in depreciation and amortization expense on the Consolidated Statement of Operations. Accumulated amortization of aircraft and other finance leases was $103.7 million and $90.5 million as of December 31, 2019 and 2018 , respectively.
Aircraft Maintenance and Repair Costs	Aircraft Maintenance and Repair Costs Maintenance and repair costs for owned and leased flight equipment, including the overhaul of aircraft components, are charged to operating expenses as incurred. Engine overhaul costs covered by power-by-the-hour arrangements are paid and expensed as incurred or expensed on a straight-line basis and are based on the amount of hours flown per contract. Under the terms of these power-by-the-hour agreements, the Company pays a set dollar amount per engine hour flown on a monthly basis and the third-party vendor assumes the obligation to repair the engines at no additional cost, subject to certain specified exclusions. As of December 31, 2019 and 2018 , the Company had approximately $100.7 million and $95.0 million , respectively in prepayments to one of its power-by-the-hour vendors, which is recoverable over the next three years . Additionally, although the Company's aircraft lease agreements specifically provide that it is responsible for maintenance of the leased aircraft, the Company pays maintenance reserves to the aircraft lessors that are applied toward the cost of future maintenance events. These reserves are calculated based on a performance measure, such as flight hours, and are available for reimbursement to the Company upon the completion of the maintenance of the leased aircraft. However, reimbursements are limited to the available reserves associated with the specific maintenance activity for which the Company requests reimbursement. Under certain aircraft lease agreements, the lessor is entitled to retain excess amounts on deposit at the expiration of the lease, if any; whereas at the expiration of certain other existing aircraft lease agreements any such excess amounts are returned to the Company, provided that it has fulfilled all of its obligations under the lease agreements. The maintenance reserves paid under the lease agreements do not transfer either the obligation to maintain the aircraft or the cost risk associated with the maintenance activities to the aircraft lessor. In addition, the Company maintains the right to select any third-party maintenance provider. Maintenance reserve payments that are expected to be recovered from lessors are recorded as deposits in the Consolidated Balance Sheets as an asset until it is less than probable that any portion of the deposit is recoverable. In addition, payments of maintenance reserves that are not substantially and contractually related to the maintenance of the leased assets are accounted for as lease payments. In order to properly account for the costs that are related to the maintenance of the leased asset, the Company bifurcates its maintenance reserves between deposits and lease payments.
Goodwill and Indefinite-lived Intangible Assets	Goodwill and Indefinite-lived Intangible Assets Goodwill and intangible assets with indefinite lives are not amortized. We apply a fair value-based impairment test to the carrying value of goodwill and indefinite-lived intangible assets on an annual basis and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. We assess the value of our goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Goodwill. When the Company evaluates goodwill for impairment using a quantitative approach, it estimates the fair value of the reporting unit by considering the market capitalization. If the reporting unit's fair value exceeds its carrying value, no further testing is required. If, however, the reporting unit's carrying value exceeds its fair value, the Company then determines the amount of the impairment charge, if any. The Company recognizes an impairment charge if the carrying value of the reporting unit's goodwill exceeds its estimated fair value. Intangible Assets. The Company assesses its indefinite-lived assets under a qualitative approach. The Company analyzes market factors to determine if events and circumstances have affected the fair value of the indefinite-lived intangible assets. If the Company determines that it is more likely than not that the asset value may be impaired, it then uses the quantitative approach to assess the asset's fair value and the amount of the impairment. The Company performs the quantitative impairment test for indefinite-lived intangible assets by comparing the asset's fair value to its carrying value.
Impairment of Long-Lived Assets and Finite-lived Intangible Assets	Impairment of Long-Lived Assets and Finite-lived Intangible Assets Long-lived assets used in operations, consisting principally of property and equipment and finite-lived intangible assets, are tested for impairment when events or changes in circumstances indicate, in management's judgment, that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amount. When testing for impairment management considers market trends, the expected useful lives of the assets, changes in economic conditions, recent transactions involving sales of similar assets and, if necessary, estimates of future undiscounted cash flows. To determine whether impairment exists for aircraft used in operations, assets are grouped at the fleet-type level (the lowest level for which there are identifiable cash flows) and future cash flows are estimated based on projections of capacity, passenger mile yield, fuel costs, labor costs and other relevant factors. If, at any time, management determines the net carrying value of an asset is not recoverable, the amount is reduced to its fair value during the period in which such determination is made. Any changes in the estimated useful lives of these assets will be accounted for prospectively.
Revenue Recognition and Costs to obtain or fulfill a contract	Revenue Recognition We record passenger ticket sales and tickets sold by other airlines for use on Hawaiian as passenger revenue when the transportation is provided or upon scheduled flight for tickets expected to expire unused. Passenger revenue associated with unused tickets, which represent unexercised passenger rights, is recognized in proportion to the pattern of rights exercised by related passengers (e.g. scheduled departure dates). To calculate the portion to be recognized as revenue in the period, the Company utilizes historical information and applies the trend rate to the current air traffic liability balances for that specific period. Ticket change fees are recorded in air traffic liability and recognized when the related transportation is provided. Certain governmental taxes are imposed on the Company's ticket sales through a fee included in ticket prices. The Company collects these fees and remits them to the appropriate government agency. Management has elected (via a practical expedient election) to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer, e.g., sales, use, value added, and certain excise taxes. These fees have been presented on a net basis in the accompanying Consolidated Statements of Operations and recorded as a liability until remitted. Costs to obtain or fulfill a contract In order for the Company to provide transportation to its customers, the Company incurs fulfillment costs (booking fees, credit card fees, and commission/selling costs), which are deferred until the period in which the flight occurs. As of December 31, 2019 and 2018 , the Company's asset balance associated with these costs were $15.7 million and $16.3 million , respectively. During the twelve months ended December 31, 2019 , 2018 , and 2017 , expenses related to these costs totaled to $91.0 million , $96.0 million , and $95.5 million , respectively. To determine the amount to capitalize and expense at the end of each period, the Company uses historical sales data and estimates the amount associated with unflown tickets.
Frequent Flier Revenue	Frequent Flyer Program HawaiianMiles, Hawaiian's frequent flyer travel award program, provides a variety of awards to program members based on accumulated mileage. ASC 606 requires the Company to account for miles earned by passengers in the HawaiianMiles program through flight activity as a component of the passenger revenue ticket transaction at the estimated selling price of the miles. Ticket consideration received is allocated between the performance obligations, primarily travel and miles earned by passengers. The allocated value of the miles is deferred until the free travel is used by the passenger, at which time it is included in revenue. The value of the ticket used in the determination of the estimated selling price is based on the historical value of equivalent flights to those provided for loyalty awards and the related miles redeemed to obtain that award adjusted for breakage or fulfillment. The equivalent ticket value (ETV) includes a fulfillment discount (breakage) to reflect the value of the award ticket over the number of miles that, based on historical experience, will be needed to obtain the award. Our estimate of ETV takes into consideration quantitative and qualitative factors, such as program changes and fares of similar tickets, and consideration of cabin class and geographic region. The Company also sells mileage credits to companies participating in our frequent flyer program. These contracts generally include multiple performance obligations, including the transportation that will ultimately be provided when the mileage credits are redeemed and marketing and brand related activities. The marketing and brand performance obligations are effectively provided each time a HawaiianMiles members uses the co-branded credit card and monthly access to customers lists and marketing is provided, which corresponds to the timing of when the Company issues or is obligated to issue the mileage credits to the HawaiianMiles member. Therefore, the Company recognize revenue for the marketing and brand performance obligation when HawaiianMiles members use their co-brand credit card and the resulting mileage credits are issued to them, which best correlates with our performance in satisfying the obligation. In 2018, the Company amended its partnership with Barclaycard US, Hawaiian's co-branded credit card partner. Management determined that the amendment should be accounted for as a termination of the existing contract and the creation of a new contract under ASC 606 and the relative selling price was determined for each performance obligation of the new agreement. The new agreement continues through 2024 and includes improved economics and enhanced product offerings for our Barclay's co-branded cardholders. The amended agreement did not change, and includes the following performance obligations; (i) transportation that will ultimately be provided when mileage credits are redeemed (transportation), (ii) the Hawaiian Airlines brand and access to its members lists (collectively, brand performance), (iii) marketing, and (iv) airline benefits to cardholders, including discounts and anniversary travel benefits, baggage waivers and inflight purchase credits. The Company determined the relative fair value of each performance obligation by estimating the selling prices of the deliverables by considering discounted cash flows using multiple inputs and assumptions, including: (1) the expected number of miles to be awarded and redeemed; (2) the estimated weighted average equivalent ticket value, adjusted by a fulfillment discount; (3) the estimated total annual cardholder spend; (4) an estimated royalty rate for the Hawaiian portfolio; and (5) the expected use of each of the airline benefits. The overall consideration received is allocated to the performance obligations based on their relative selling prices. Accounting for frequent flyer revenue involves the use of various techniques to estimate revenue. To determine the total estimated transaction price, the Company forecasts future credit card activity based on historical data. The relative selling price is determined using management’s estimated standalone selling price of each performance obligation. The objective of using the estimated selling price based methodology is to determine the price at which the Company would transact a sale if the product or service were sold on a standalone basis. Accordingly, the Company determines our best estimate of selling price by considering multiple inputs and methods including, but not limited to, discounted cash flows, brand value, number of miles awarded and number of miles redeemed. The Company estimates the selling price of miles using an ETV adjusted for a fulfillment discount as described above. Miles expire after 18 months of member account inactivity. The Company reviews its breakage estimates, which impacts ETV and loyalty recognition patterns, annually based upon the latest available information regarding redemption and expiration patterns (e.g., credit card and non-credit card holders). The Company's estimate of the expected expiration of miles requires significant management judgment. Current and future changes to expiration assumptions or to the expiration policy, or to program rules and program could affect the estimated value of a mile.
Accounts Receivable	Accounts Receivable Accounts receivable primarily consist of amounts due from credit card companies, non-airline partners, and cargo transportation customers. The Company provides an allowance for uncollectible accounts equal to the estimated losses expected to be incurred based on historical chargebacks, write-offs, bankruptcies and other specific analyses. Bad debt expense was not material in any period presented.
Pension and Postretirement and Postemployment Benefits	Pension and Postretirement and Postemployment Benefits The Company accounts for its defined benefit pension and other postretirement and postemployment plans in accordance with ASC 715, Compensation—Retirement Benefits (ASC 715), which requires companies to measure their plans' assets and obligations to determine the funded status at fiscal year-end, reflect the funded status in the statement of financial position as an asset or liability, and recognize changes in the funded status of the plans in comprehensive income during the year in which the changes occur. Pension and other postretirement and postemployment benefit expenses are recognized on an accrual basis over each employee's service periods. Pension expense is generally independent of funding decisions or requirements. The Company uses the corridor approach in the valuation of its defined benefit pension and other postretirement and postemployment plans. The corridor approach defers all actuarial gains and losses resulting from variances between actual results and actuarial assumptions. These unrecognized actuarial gains and losses are amortized when the net gains and losses exceed 10% of the greater of the market-related value of plan assets or the projected benefit obligation at the beginning of the year. The amount in excess of the corridor is amortized over the expected average remaining service period of active plan participants for the open plans and is amortized over the expected average remaining lifetime of inactive participants for plans whose population is “all or almost all” inactive.
Advertising Costs	Advertising Costs
Capitalized Interest	Capitalized Interest Interest is capitalized upon the payment of predelivery deposits for aircraft and engines, and is depreciated over the estimated useful life of the asset from service inception date.
Share-Based Compensation	Share-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair value of the awards are estimated using the following: (1) option-pricing models for grants of stock options or (2) fair value at the measurement date (usually the grant date) for awards of stock subject to service and / or performance-based vesting. The resulting cost is recognized as compensation expense over the period of time during which an employee is required to provide services to the Company (the service period) in exchange for the award, the service period generally being the vesting period of the award. The Company's policy is to recognize forfeitures as they occur.
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 aircraft fuel prices, interest rates and foreign currency exchange rates. The following table summarizes the accounting treatment of the Company's derivative contracts: Derivative Type Accounting Designation Classification of Realized Gains and Losses Classification of Unrealized Gains (Losses) Foreign currency exchange contracts Designated as cash flow hedges Passenger revenue AOCI Fuel hedge contracts Not designated as hedges Gains (losses) on fuel derivatives Change in fair value is recorded in nonoperating income (expense) Foreign currency exchange contracts Not designated as hedges Nonoperating income (expense), Other Change in fair value is recorded in nonoperating income (expense) If the Company terminates a derivative designated for hedge accounting under ASC 815, prior to its contractual settlement date, then the cumulative gain or loss recognized in AOCI at the termination date remains in AOCI until the forecasted transaction occurs. In a situation where it becomes probable that a hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. All cash flows associated with purchasing and settling derivatives are classified as operating cash flows in the Consolidated Statements of Cash Flows.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (ASU 2016-02), which was subsequently codified within ASC 842, Leases . ASC 842 requires a lessee to recognize a right-of-use asset and a lease liability in the statement of financial position for all leases (with the exception of short-term leases) at the lease commencement date and recognize expenses similar to the current ASC 840, Leases. ASC 842 is effective for fiscal years, and interim periods beginning after December 15, 2018. The Company adopted ASC 842 as of January 1, 2019 using the transition method that provides for a cumulative-effect adjustment to retained earnings upon adoption. The Company elected the package of transition provisions available for expired or existing contracts, which allows the Company to carry-forward our historical assessments of (a) whether contracts are, or contain, leases, (b) lease classification, and (c) initial direct costs. The adoption of the ASC 842 had a significant impact on the Company's consolidated balance sheet due to the recognition of approximately $603.9 million of operating lease liabilities and ROU assets for operating leases of $649.3 million . Additionally, the Company recognized a $4.9 million (net of tax of $1.6 million ) cumulative effect adjustment credit to retained earnings. The adjustment to retained earnings was driven principally by ASC 842's elimination of the previous build-to-suit lease accounting guidance under ASC 840, and resulted in the derecognition of build-to-suit assets and liabilities that remained on the balance sheet after the end of the construction period. ASC 842 then required the application of lease accounting to the agreement, which resulted in an operating lease. This resulted in the recognition of a ROU asset, inclusive of building costs incurred by the Company to place the asset into service, of $124.7 million , and a lease liability of $90.8 million . The Consolidated Financial Statements as of and for the twelve months ended December 31, 2019 are presented under the new standard, while comparative periods presented are not adjusted and continue to be reported in accordance with our historical accounting policy. See Note 10 for additional information. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12), which better aligns a company's risk management activities and financial reporting for hedging relationships and is intended to simplify hedge accounting requirements. ASU 2017-12 was effective for annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted this standard during the first quarter of 2019. The adoption of this standard did not have an impact on the Company's Consolidated Financial Statements. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (ASU 2016-13), which requires the use of an "expected loss" model on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU 2016-13 replaces the incurred loss methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted. The Company will adopt ASU 2016-13 effective January 1, 2020. The Company does not expect that the adoption of the standard will have a significant impact on its consolidated financial statements.

The transactions are described below: In February 2018, the Company exercised its right to terminate the aircraft purchase agreement between the Company and Airbus for six Airbus A330-800neo aircraft and the purchase rights for an additional six Airbus A330-800neo aircraft. To terminate the purchase agreement, the Company was obligated to repay Airbus for concessions received relating to a prior firm order, training credits, as well as forfeit the pre-delivery progress payments made towards the flight equipment. The Company recorded a contract terminations expense to reflect a portion of the termination penalty within the Consolidated Statements of Operations. In January 2018, the Company entered into a transaction with its lessor to early terminate and purchase three Boeing 767-300 aircraft leases and concurrently entered into a forward sale agreement for the same three Boeing 767-300 aircraft, including two Pratt & Whitney 4060 engines for each aircraft. These aircraft were previously accounted for as operating leases. In order to exit the lease and purchase the aircraft, the Company agreed to pay a total of $67.1 million (net of all deposits) of which a portion was expensed immediately and recognized as a contract termination fee. The expensed amount represents the total purchase price amount over fair value of the aircraft purchased as of the date of the transaction. Special items (2) In August 2017, the Company terminated the Hawaiian Airlines, Inc. Salaried & IAM Merged Pension Plan (the Merged Plan) and settled a portion of its pilots' other post-retirement medical plan liability. In connection with the reduction of these liabilities, the Company recorded one-time Other nonoperating special charges of $35.2 million related to the Merged Plan termination and $10.4 million related to the other post-retirement (OPEB) medical plan partial settlement. (3) In April 2017, the Company executed a sale leaseback transaction with an independent third party for three Boeing 767-300 aircraft. The lease terms for the three aircraft commenced in April 2017 and end between November 2018 through January 2019. During the twelve months ended December 31, 2017, the Company recorded a loss on sale of aircraft of $4.8 million . (4) In February 2017, the Company reached a tentative agreement with Air Line Pilots Association (ALPA), covering the Company's pilots. In March 2017, the Company received notice from ALPA that the agreement was ratified by ALPA's members. The agreement became effective April 1, 2017 and has a term of 63 months. The agreement includes, among other various benefits, a pay adjustment and ratification bonus computed based on previous service. During the twelve months ended December 31, 2017, the Company expensed $18.7 million principally related to a one-time payment to reduce the Company's future 401K employer contribution for certain pilot groups, which is not recoverable once paid.
