Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation Hawaiian Holdings, Inc. (the Company or Holdings) is a holding company 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 Airlines, Inc. (Hawaiian). The accompanying unaudited financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (SEC). Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company’s results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the airline industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year. The accompanying unaudited Consolidated Financial Statements should be read in conjunction with the financial statements and the notes of the Company included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 .

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Recently Adopted Accounting Pronouncements In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, requiring an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. ASU 2017-07 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption only permitted in the first quarter of 2017. The Company early adopted this standard during the first quarter of 2017. The adoption of ASU 2017-07 resulted in a reclassification of $5.1 million from wages and benefits to other components of net periodic benefit cost on the Company's consolidated statement of operations for three months ended March 31, 2016 . In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows, Restricted Cash, requiring restricted cash and restricted cash equivalents to be included with cash and cash equivalents on the statement of cash flows when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company early adopted this standard during the first quarter of 2017. Restricted cash is now included as a component of cash, cash equivalents, and restricted cash on the Company's condensed consolidated statement of cash flows. The inclusion of restricted cash increased the beginning balances of the condensed consolidated statement of cash flows by $5.0 million and the ending balances by $1.0 million and $5.0 million for the three months ended March 31, 2017 and 2016 , respectively. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments. The new standard clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company early adopted this standard during the first quarter of 2017. The adoption of this guidance did not impact the Company's consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, requiring all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. ASU 2016-09 will also allow an employer to withhold more shares for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The primary impact of the adoption of the standard on the Company's consolidated financial statements was the recognition of excess tax benefits in the provision for income taxes rather than additional paid-in capital, which reduced income tax expense by $5.2 million for the three months ended March 31, 2017. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, requiring a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018. ASU 2016-02 requires entities to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. Full retrospective application is prohibited. The Company is currently evaluating the effect that the provisions of ASU 2016-02 will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and allows for either full retrospective or modified retrospective adoption. The Company is currently evaluating the overall effect that the provisions of ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has determined that the new standard, once effective, will affect frequent flyer, ticket breakage, and airline ticket change fee accounting. The standard will preclude the Company from applying the incremental cost method of accounting for free travel awards earned by passengers issued from the HawaiianMiles program through flight activity. The Company will instead be required to allocate consideration received between the ticket and miles earned by passengers and defer the value of the miles until redemption, resulting in a significant increase to the deferred revenue liability on the balance sheet. Passenger revenue is currently recognized for unflown tickets when tickets expire unused. Under the new standard, the Company expects to estimate tickets that will expire unused and recognize revenue at the ticketed flight date. Fees for changing itineraries are currently recognized when received. The Company expects to defer the recognition of these fees until the related transportation is provided. Amounts currently classified in other revenue (e.g. bag and other ancillary fees) will be reclassified to passenger revenue. These changes could have a significant impact on the Company's 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. For the three months ended March 31, 2017 and 2016 , anti-dilutive shares excluded from the calculation of diluted earnings per share were not material.

The stock repurchase program is subject to modification or termination at any time. The Company had no stock repurchase activity during the three months ended March 31, 2017 . As of March 31, 2017 , the Company had $46.0 million remaining to spend under the stock repurchase program. In April 2017, the Company's Board of Directors approved a modification to the stock repurchase program. Such modification extends the stock repurchase program through May 2019 and increases the current share authorization to $100 million of the Company's outstanding common stock.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurement (ASC 820) defines fair value as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term for the assets or liabilities; and Level 3 — Unobservable inputs for which there is little or no market data and that are significant to the fair value of the assets or liabilities. The tables below present the Company’s financial assets and liabilities measured at fair value on a recurring basis: Fair Value Measurements as of March 31, 2017 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 259,654 $ 230,681 $ 28,973 $ — Restricted cash 1,000 1,000 — — Short-term investments 273,700 — 273,700 — Fuel derivative contracts: Crude oil call options 4,597 — 4,597 — Heating oil swaps 876 — 876 — Foreign currency derivatives 5,353 — 5,353 — Total assets measured at fair value $ 545,180 $ 231,681 $ 313,499 $ — Fuel derivative contracts: Heating oil swaps $ 146 $ — $ 146 $ — Foreign currency derivatives 5,443 — 5,443 — Total liabilities measured at fair value $ 5,589 $ — $ 5,589 $ — Fair Value Measurements as of December 31, 2016 Total Level 1 Level 2 Level 3 (in thousands) Cash equivalents $ 123,120 $ 104,113 $ 19,007 $ — Restricted cash 5,000 5,000 — — Short-term investments 284,075 — 284,075 — Fuel derivative contracts: Crude oil call options 8,489 — 8,489 — Heating oil swaps 6,601 — 6,601 — Foreign currency derivatives 12,906 — 12,906 — Total assets measured at fair value $ 440,191 $ 109,113 $ 331,078 $ — Foreign currency derivatives 1,469 — 1,469 — Total liabilities measured at fair value $ 1,469 $ — $ 1,469 $ — Cash equivalents. The Company's level 1 cash equivalents consist of money market securities and the level 2 cash equivalents consist of U.S. agency bonds, mutual funds, and commercial paper. The instruments classified as level 2 are valued using quoted prices for similar assets in active markets. Restricted cash . The Company’s restricted cash consists of cash held as collateral by institutions that process our credit card transactions for advanced ticket sales, which is valued similarly to the money market securities held as cash equivalents. Short-term investments. Short-term investments include U.S. and foreign government notes and bonds, U.S. agency bonds, variable-rate corporate bonds, asset backed securities, foreign and domestic corporate bonds, municipal bonds, and commercial paper. These instruments are valued using quoted prices for similar assets in active markets or other observable inputs. Fuel derivative contracts. The Company’s fuel derivative contracts consist of heating oil swaps and crude oil call options which are not traded on a public exchange. The fair value of these instruments are determined based on inputs available or derived from public markets including contractual terms, market prices, yield curves, and measures of volatility among others. Foreign currency derivatives. The Company’s foreign currency derivatives consist of Japanese Yen and Australian Dollar forward contracts and are valued based primarily on data available or derived from public markets. The table below presents the Company’s debt (excluding obligations under capital leases) measured at fair value: Fair Value of Debt March 31, 2017 December 31, 2016 Carrying Fair Value Carrying Fair Value Amount Total Level 1 Level 2 Level 3 Amount Total Level 1 Level 2 Level 3 (in thousands) $ 463,068 $ 466,147 $ — $ — $ 466,147 $ 481,874 $ 484,734 $ — $ — $ 484,734 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 instruments. 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 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. During the three months ended March 31, 2017 , the Company primarily used heating oil swaps and crude oil call options to hedge its aircraft fuel expense. These derivative instruments 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 unaudited Consolidated Statements of Operations. Three months ended March 31, Fuel derivative contracts 2017 2016 (in thousands) Gains (losses) realized at settlement $ 2,589 $ (19,025 ) Reversal of prior period unrealized amounts (7,947 ) 17,810 Unrealized losses that will settle in future periods (3,440 ) (850 ) Losses on fuel derivatives recorded as Nonoperating Income (expense) $ (8,798 ) $ (2,065 ) 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 effective portion of the gain or loss of designated cash flow hedges is reported as a component of accumulated other comprehensive income (AOCI) and reclassified into earnings in the same period in which the related sales are recognized as passenger revenue. The effective portion of the foreign currency forward contracts represents the change in fair value of the hedge that offsets the change in the fair value of the hedged item. To the extent the change in the fair value of the hedge does not perfectly offset the change in the fair value of the hedged item, the ineffective portion of the hedge is immediately recognized as nonoperating income (expense). Foreign currency forward contracts that are not designated as cash flow hedges are recorded at fair value, and any changes in fair value are recognized as other nonoperating income (expense) in the period of change. The Company believes that its foreign currency forward contracts that are designated as cash flow hedges will continue to be effective in offsetting changes in cash flow attributable to the hedged risk. The Company expects to reclassify a net loss of approximately $0.4 million into earnings over the next 12 months from AOCI based on the values at March 31, 2017 . 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 unaudited 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) regularly 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 by the counterparties based on the current market exposure of the derivative. 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 counterparties as of March 31, 2017 and December 31, 2016 . 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.

The Company also has operating commitments with third-party service providers for IT, accounting services, and a capacity purchase agreement through 2024. Committed capital and operating expenditures include escalation amounts based on estimates. The gross committed expenditures and committed payments for those deliveries as of March 31, 2017 are detailed below: Capital Operating Total Committed (in thousands) Remaining in 2017 $ 204,880 $ 59,351 $ 264,231 2018 409,234 64,378 473,612 2019 489,159 58,683 547,842 2020 236,380 57,316 293,696 2021 165,643 54,974 220,617 Thereafter 129,870 390,870 520,740 $ 1,635,166 $ 685,572 $ 2,320,738 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. These holdbacks, which are included in restricted cash in the Company’s unaudited Consolidated Balance Sheets, totaled $1.0 million at March 31, 2017 and $5.0 million at December 31, 2016 . In the event of a material adverse change in the Company's 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. If the Company is unable to obtain a waiver of, or otherwise mitigate the increase in the restriction of cash, it could have a material adverse impact on the Company.

Significant Accounting Polici22

Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2017
Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements; Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, requiring an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. ASU 2017-07 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption only permitted in the first quarter of 2017. The Company early adopted this standard during the first quarter of 2017. The adoption of ASU 2017-07 resulted in a reclassification of $5.1 million from wages and benefits to other components of net periodic benefit cost on the Company's consolidated statement of operations for three months ended March 31, 2016 . In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows, Restricted Cash, requiring restricted cash and restricted cash equivalents to be included with cash and cash equivalents on the statement of cash flows when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company early adopted this standard during the first quarter of 2017. Restricted cash is now included as a component of cash, cash equivalents, and restricted cash on the Company's condensed consolidated statement of cash flows. The inclusion of restricted cash increased the beginning balances of the condensed consolidated statement of cash flows by $5.0 million and the ending balances by $1.0 million and $5.0 million for the three months ended March 31, 2017 and 2016 , respectively. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments. The new standard clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company early adopted this standard during the first quarter of 2017. The adoption of this guidance did not impact the Company's consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, requiring all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. ASU 2016-09 will also allow an employer to withhold more shares for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The primary impact of the adoption of the standard on the Company's consolidated financial statements was the recognition of excess tax benefits in the provision for income taxes rather than additional paid-in capital, which reduced income tax expense by $5.2 million for the three months ended March 31, 2017. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases, requiring a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018. ASU 2016-02 requires entities to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. Full retrospective application is prohibited. The Company is currently evaluating the effect that the provisions of ASU 2016-02 will have on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and allows for either full retrospective or modified retrospective adoption. The Company is currently evaluating the overall effect that the provisions of ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has determined that the new standard, once effective, will affect frequent flyer, ticket breakage, and airline ticket change fee accounting. The standard will preclude the Company from applying the incremental cost method of accounting for free travel awards earned by passengers issued from the HawaiianMiles program through flight activity. The Company will instead be required to allocate consideration received between the ticket and miles earned by passengers and defer the value of the miles until redemption, resulting in a significant increase to the deferred revenue liability on the balance sheet. Passenger revenue is currently recognized for unflown tickets when tickets expire unused. Under the new standard, the Company expects to estimate tickets that will expire unused and recognize revenue at the ticketed flight date. Fees for changing itineraries are currently recognized when received. The Company expects to defer the recognition of these fees until the related transportation is provided. Amounts currently classified in other revenue (e.g. bag and other ancillary fees) will be reclassified to passenger revenue. These changes could have a significant impact on the Company's financial statements.
