Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation JetBlue Airways Corporation ("JetBlue") provides air transportation services across the United States, the Caribbean, Latin America, Canada, and Europe. Our condensed consolidated financial statements include the accounts of JetBlue and our subsidiaries which are collectively referred to as "we" or the "Company." All majority-owned subsidiaries are consolidated on a line-by-line basis, with all intercompany transactions and balances being eliminated. These condensed consolidated financial statements and related notes should be read in conjunction with our 2023 audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Form 10-K"). These condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC"). In our opinion, they reflect all adjustments, including normal recurring items, that are necessary to present fairly the results for interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed or omitted as permitted by such rules and regulations; however, we believe that the disclosures included herein are adequate to make the information presented not misleading.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company categorizes revenue recognized from contracts with its customers by revenue source as we believe it best depicts the nature, amount, timing, and uncertainty of our revenue and cash flow. The following table provides revenue recognized by revenue source for the three and six months ended June 30, 2024 and 2023 (in millions): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Passenger revenue Passenger travel $ 2,085 $ 2,289 $ 3,972 $ 4,315 Loyalty revenue - air transportation 180 171 347 326 Other revenue Loyalty revenue 114 104 221 204 Other revenue 49 46 97 92 Total operating revenue $ 2,428 $ 2,610 $ 4,637 $ 4,937 TrueBlue ® is our customer loyalty program designed to reward and recognize our customers. TrueBlue ® points earned from ticket purchases are recorded as a reduction to Passenger travel within passenger revenue. Amounts presented in Loyalty revenue - air transportation represent revenue recognized when TrueBlue ® points have been redeemed and travel has occurred. Loyalty revenue within other revenue is primarily comprised of the non-air transportation elements from the sale of TrueBlue ® points. Contract Liabilities Our contract liabilities primarily consist of ticket sales for which transportation has not yet been provided, unused credits available to customers, and outstanding loyalty points available for redemption (in millions): June 30, 2024 December 31, 2023 Air traffic liability - passenger travel $ 1,248 $ 1,099 Air traffic liability - loyalty program (air transportation) 1,072 1,072 Deferred revenue (1) 452 487 Total $ 2,772 $ 2,658 (1) Deferred revenue is included within other accrued liabilities and other liabilities on our consolidated balance sheets. We recognized passenger rev enue o f $1.1 billion for each of the six months ended June 30, 2024 and 2023, which was included in passenger travel liability at the beginning of the respective periods. The Company elected the practical expedient that allows entities to not disclose the amount of the remaining transaction price and its expected timing of recognition for passenger tickets if the contract has an original expected duration of one year or less or if certain other conditions are met. We elected to apply this practical expedient to our contract liabilities relating to passenger travel and ancillary services as our tickets or any related passenger credits expire generally one year from the date of booking. TrueBlue ® points are combined into one homogeneous pool and are not separately identifiable. As such, the revenue is comprised of points that were part of the air traffic liability balance at the beginning of the period as well as points that were issued during the period. The table below presents the activity of the current and non-current air traffic liability for our loyalty program, and includes points earned and sold to participating companies for the six months ended June 30, 2024 and 2023 (in millions): Balance at December 31, 2023 $ 1,072 TrueBlue ® points redeemed passenger (347) TrueBlue ® points redeemed other (14) TrueBlue ® points earned and sold 361 Balance at June 30, 2024 $ 1,072 Balance at December 31, 2022 $ 1,000 TrueBlue ® points redeemed passenger (327) TrueBlue ® points redeemed other (10) TrueBlue ® points earned and sold 327 Balance at June 30, 2023 $ 990 The timing of our TrueBlue ® point redemptions can vary; however, the majority of points are redeemed within approximately three years of the date of issuance.

Debt Disclosure [Abstract]
Long-term Debt, Short-term Borrowings and Finance Lease Obligations	Long-term Debt, Short-term Borrowings and Finance Lease Obligations During the six months ended June 30, 2024, we made principal payments of $166 million on our outstanding debt and finance lease obligations. At June 30, 2024, we had pledged aircraft, engines, other equipment, and facilities with a net book value of $6.8 billion as security under various financing arrangements. At June 30, 2024, scheduled maturities of our long-term debt and finance lease obligations were as follows (in millions): Year Total Remainder of 2024 $ 173 2025 333 2026 1,080 2027 335 2028 436 Thereafter 3,013 Total $ 5,370 The carrying amounts and estimated fair values of our long-term debt, net of debt acquisition costs, at June 30, 2024 and December 31, 2023 were as follows (in millions): June 30, 2024 December 31, 2023 Carrying Value Estimated Fair Value (1) Carrying Value Estimated Fair Value (1) Public Debt Fixed rate special facility bonds, due through 2036 $ 42 $ 43 $ 42 $ 43 Fixed rate enhanced equipment notes: 2019-1 Series AA, due through 2032 463 474 476 474 2019-1 Series A, due through 2028 144 148 149 150 2019-1 Series B, due through 2027 63 78 70 86 2020-1 Series A, due through 2032 485 587 506 597 2020-1 Series B, due through 2028 108 138 117 150 Non-Public Debt Fixed rate equipment notes, due through 2028 267 258 322 305 Floating rate equipment notes, due through 2036 (2) 375 435 109 113 Aircraft sale-leaseback transactions, due through 2036 2,075 2,274 1,648 1,738 Unsecured CARES Act Payroll Support Program loan, due through 2030 259 194 259 184 Unsecured Consolidated Appropriations Act Payroll Support Program Extension loan, due through 2031 144 107 144 101 Unsecured American Rescue Plan Act of 2021 Payroll Support loan, due through 2031 132 98 132 93 0.50% convertible senior notes due through 2026 744 682 742 657 Total (3) $ 5,301 $ 5,516 $ 4,716 $ 4,691 (1) The estimated fair va lues of our publicly held long-term debt are classified as Level 2 in the fair value hierarchy. The fair values of our non-public debt are estimated using a discounted cash flow analysis based on our borrowing rates for instruments with similar terms and therefore classified as Level 3 in the fair value hierarchy. The fair values of our other financial instruments approximate their carrying values. Refer to Note 7 for an explanation of the fair value hierarchy structure. (2) Debt bears interest at a floating rate equal to Secured Overnight Financing Rate ("SOFR"), plus a margin. (3) Total excludes finance lease obligations of $69 million at June 30, 2024 and an immaterial amount at December 31, 2023. We have financed certain aircraft with Enhanced Equipment Trust Certificates ("EETCs"). One of the benefits of this structure is being able to finance several aircraft at one time, rather than individually. The structure of EETC financing is that we create pass-through trusts in order to issue pass-through certificates. The proceeds from the issuance of these certificates are then used to purchase equipment notes which are issued by us and are secured by our aircraft. These trusts meet the definition of a variable interest entity ("VIE"), as defined in Topic 810, Consolidation of the Financial Accounting Standards Board ("FASB") Codification, and must be considered for consolidation in our financial statements. Our assessment of our EETCs considers both quantitative and qualitative factors including the purpose for which these trusts were established and the nature of the risks in each. The main purpose of the trust structure is to enhance the creditworthiness of our debt obligation through certain bankruptcy protection provisions and liquidity facilities, and also to lower our total borrowing cost. We concluded that we are not the primary beneficiary in these trusts because our involvement in them is limited to principal and interest payments on the related notes, the trusts were not set up to pass along variability created by credit risk to us, and the likelihood of our defaulting on the notes. Therefore, we have not consolidated these trusts in our financial statements. 2024 Floating Rate Equipment Notes In May 2024, JetBlue entered into an agreement to finance certain aircraft for an aggregate principal amount of $281 million, bearing interest at a floating rate of SOFR plus a margin. Debt incurred matures on an aircraft-by-aircraft basis from December 2027 to June 2036, with principal and interest payable quarterly in arrears. 2024 Sale-Leaseback Transactions During the six months ended June 30, 2024, we entered into $470 million of sale-leaseback transactions. These transactions did not qualify as sales for accounting purposes. The assets associated with these transactions remain on our consolidated balance sheets within property and equipment and the related liabilities under the lease are classified within debt and finance leases obligations. These transactions are treated as cash from financing activities on our condensed consolidated statements of cash flows. Short-term Borrowings Citibank Line of Credit As previously disclosed, on October 21, 2022, JetBlue entered into the $600 million Second Amended and Restated Credit and Guaranty Agreement (the "Facility"), among JetBlue, Citibank N.A., as administrative agent, and the lenders party thereto. On July 29, 2024, the Company entered into the Second Amendment to the Second Amended and Restated Credit and Guaranty Agreement, which modifies the Facility to, among other things, (i) extend the final maturity of the Facility to October 21, 2029; provided that if the Company’s convertible senior notes due 2026 are not extended, refinanced or paid off, subject to a specified minimum outstanding principal amount thereof, then the Facility expiration will be automatically shortened to December 31, 2025; (ii) adjust the margin and the minimum liquidity requirements of the Company; (iii) replace the sustainability adjustment mechanism; (iv) allow for certain additions of eligible collateral; and (v) remove provisions relating to the terminated merger agreement with Spirit Airlines, Inc. As of and for the periods ended June 30, 2024 and December 31, 2023, we did not have a balance outstanding or any borrowings under the Facility. Morgan Stanley Line of Credit We have a revolving line of credit with Morgan Stanley for up to approximately $200 million. This line of credit is secured by a portion of our investment securities held by Morgan Stanley and the amount available to us under this line of credit may vary accordingly. This line of credit bears interest at a floating rate based upon LIBOR (or such replacement index as the bank shall determine from time to time in accordance with the terms of the agreement), plus a margin. As of and for the periods ended June 30, 2024 and December 31, 2023, we did not have a balance outstanding or any borrowings under this line of credit. 2022 $3.5 Billion Senior Secured Bridge Facility JetBlue entered into a Second Amended and Restated Commitment Letter (the "Commitment Letter"), dated July 28, 2022, with Goldman Sachs Bank USA; BofA Securities, Inc.; Bank of America, N.A.; BNP Paribas; Credit Suisse AG, New York Branch; Credit Suisse Loan Funding LLC; Credit Agricole Corporate and Investment Bank; Natixis, New York Branch; Sumitomo Mitsui Banking Corporation; and MUFG Bank, Ltd.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding. Diluted earnings (loss) per share is calculated similarly but includes potential dilution from restricted stock units, the crewmember stock purchase plan, convertible notes, warrants issued under various federal payroll support programs, and any other potentially dilutive instruments using the treasury stock and if-converted method. There were no anti-dilutive common stock equivalents excluded from the computation of diluted earnings per share amounts for the three months ended June 30, 2024 and June 30, 2023, respectively. Anti-dilutive common stock equivalents excluded from the computation of diluted earnings (loss) per share amounts w ere 3.6 million and 1.7 million for the six months ended June 30, 2024 and June 30, 2023, respectively . The following table shows how we computed earnings (loss) per common share for the three and six months ended June 30, 2024 and 2023 (dollars and share data in millions): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Net income (loss) $ 25 $ 138 $ (691) $ (54) Weighted average basic shares 345.1 331.9 342.7 330.0 Effect of dilutive securities 3.8 1.7 — — Weighted average diluted shares $ 348.9 $ 333.6 $ 342.7 $ 330.0 Earnings (loss) per common share Basic $ 0.07 $ 0.41 $ (2.02) $ (0.16) Diluted $ 0.07 $ 0.41 $ (2.02) $ (0.16)

Crewmember Retirement Plan

Crewmember Retirement Plan	6 Months Ended

Retirement Benefits [Abstract]
Crewmember Retirement Plan	Crewmember Retirement Plan We sponsor a retirement savings 401(k) defined contribution plan (the "Plan"), covering our U.S. and Puerto Rico crewmembers, where we match 100% of our eligible crewmember's contributions up to 5% of their eligible wages. Employer contributions vest after three years of service and are measured from a crewmember's hire date. Crewmembers are vested immediately in their voluntary contributions. Certain Federal Aviation Administration (" FAA" ) licensed crewmembers received a discretionary contribution of 3% of eligible compensation, which we refer to as Retirement Advantage. As of January 2024, the Retirement Advantag e program ended and these licensed Crewmembers now receive a discretionary contribution of 8% of eligible compensation, which we refer to as Retirement Non-elective Licensed Crewmember contributions. System Controllers also receive a Company discretionary contribution of 5% of eligible compensation, referred to as Retirement Non-elective Crewmember contributions. The Company’s non-elective contributions vests after three years of service. Our Pilots receive a non-elective Company contribution of 16% of eligible compensation per the terms of the finalized collective bargaining agreement between JetBlue and the Air Line Pilots Association ("ALPA"), in lieu of the above 401(k) Company matching contribution, Retirement Non-elective , and Retirement Advantage contributions . The Company's non-elective contribution of eligible Pilot compensation vests after three years of service. Total 401(k) company match and non-elective crewmember contribution expense for the three months ended June 30, 2024 and 2023 was $61 million and $72 million, respectively and for the six months ended June 30, 2024 and 2023 was $127 million and $138 million, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Flight Equipment Commitments Our committed expenditures for aircraft and related flight equipment, including estimated amounts for contractual price escalations and pre-delivery deposits, are set forth in the table below (in millions): Flight Equipment Commitments (1) Year Total Remainder of 2024 $ 483 2025 982 2026 716 2027 192 2028 262 Thereafter 3,910 Total $ 6,545 (1) On July 26, 2024, JetBlue and Airbus S.A.S. ("Airbus") entered into an amended delivery schedule pursuant to which we agreed to defer 44 Airbus A321neo aircraft originally scheduled for delivery from 2025 through 2029 to revised delivery dates of 2030 and beyond. The table above and the Firm Aircraft Orders table below reflect our aircraft purchase commitments after giving effect to this revised delivery schedule. Our firm aircraft orders include the following aircraft: Firm Aircraft Orders (1) Year Airbus A220 Airbus A321neo Total Remainder of 2024 12 1 13 2025 20 4 24 2026 20 — 20 2027 5 — 5 2028 7 — 7 Thereafter 4 44 48 Total (2) 68 49 117 (1) Refer to the Flight Equipment Commitments table above for additional information on the amended Airbus delivery schedule. (2) In addition, we have options to purchase 20 A220-300 aircraft between 2027 and 2028. Other Commitments and Contingencies We utilize several credit card processors to process our ticket sales. Our agreements with these processors do not contain covenants, but do generally allow the processor to withhold cash reserves to protect the processor from potential liability for tickets purchased, but not yet used for travel. While we currently do not have any collateral requirements related to our credit card processors, we may be required to issue collateral to our credit card processors, or other key business partners, in the future. As of June 30, 2024, we had $57 million in restricted cash assets serving as collateral for letters of credit relating to a certain number of our leases, which will expire at the end of the related lease terms. We also had a $65 million letter of credit relating to our 5% ownership in JFK Millennium Partner LLC, a private entity that will finance, develop, and operate John F. Kennedy International Airport ("JFK") Terminal 6. The letters of credit are included in restricted cash on the consolidated balance sheets. Additionally, we had $9 million cash pledged primarily related to other business partner agreements, which will expire according to the terms of the related agreements. Labor Unions and Non-Unionized Crewmembers As of June 30, 2024, 51% of our full-time equivalent crewmembers were represented by labor unions. The pilot group, which represents 22% of our full-time equivalent crewmembers, is covered by a collective bargaining agreement ("CBA"). Negotiations for an amended CBA began in May 2024. Our pilots are represented by ALPA. Our inflight crewmembers and flight instructors are represented by the Transport Workers Union of America ("TWU"); our other frontline crewmembers do not have third party representation. ALPA In January 2023, JetBlue pilots ratified a two-year contract extension effective March 1, 2023, which included a ratification payment and adjustments to paid-time-off accruals resulting from the pay rate increases of $95 million. This expense is included within special items. TWU On July 14, 2022, TWU filed a representation application with the National Mediation Board ("NMB") seeking an election among the 35 pilot instructors (called "Flight Instructors"). JetBlue disputed TWU’s application alleging that "Flight Instructors" do not constitute a craft or class. On October 26, 2023, the NMB notified the participants that it rejected JetBlue’s argument and ordered an election. The Flight Instructors voted for TWU representation. Contract negotiations for an initial CBA began in April 2024. Non-Unionized Crewmembers We enter into individual employment agreements with each of our non-unionized FAA-licensed crewmembers, which include dispatchers, technicians, inspectors, and air traffic controllers. Each employment agreement is for a term of five years and automatically renews for an additional five years unless either the crewmember or we elect not to renew it by giving at least 90 days' notice before the end of the relevant term. Pursuant to these agreements, these crewmembers can only be terminated for cause. In the event of a downturn in our business that would require a reduction in work hours, we are obligated to pay these crewmembers a guaranteed level of income and to continue their benefits if they do not obtain other aviation employment. Legal Matters Occasionally, we are involved in various claims, lawsuits, regulatory examinations, investigations, and other legal matters involving suppliers, crewmembers, customers, and governmental agencies, arising, for the most part, in the ordinary course of business. The outcome of litigation and other legal matters is always uncertain. The Company believes it has valid defenses to the legal matters currently pending against it, is defending itself vigorously, and has recorded accruals determined in accordance with GAAP, where appropriate. In making a determination regarding accruals, using available information, we evaluate the likelihood of an unfavorable outcome in legal or regulatory proceedings to which we are a party and record a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of our defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from our current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to our condensed consolidated results of operations, liquidity, or financial condition. To date, none of these types of litigation matters, most of which are typically covered by insurance, has had a material impact on our operations or financial condition. We have insured and continue to insure against most of these types of claims. A judgment on any claim not covered by, or in excess of, our insurance coverage could materially adversely affect our condensed consolidated results of operations, liquidity, or financial condition. As previously disclosed, in July 2020, JetBlue and American Airlines Group Inc. ("American") entered into the Northeast Alliance (the "NEA"), which was designed to optimize our respective networks at JFK Airport, LaGuardia Airport, Newark Liberty International Airport, and Boston Logan International Airport. On September 21, 2021, the United States Department of Justice, along with the Attorneys General of six states and the District of Columbia filed suit against JetBlue and American seeking to enjoin the NEA, alleging that it violated Section 1 of the Sherman Act. The court issued a decision on May 19, 2023, permanently enjoining the NEA, and shortly thereafter we initiated a wind down of the NEA. On July 28, 2023, the court issued its Final Judgement and Order Entering Permanent Injunction, which took effect on August 18, 2023 (the "Final Injunction"). The wind down of the NEA is substantially complete, but remaining impacts could require us to incur additional costs and therefore have an impact on our financial condition and results of operations. In December 2022 and February 2023, four putative class actions lawsuits were filed in the United States District Court for the Eastern District of New York and the United States District Court for the District of Massachusetts, respectively, alleging that the NEA violates Sections 1 and 2 of the Sherman Act. Among other things, plaintiffs seek monetary damages on behalf of a putative class of direct purchasers of airline tickets from JetBlue and American and, depending on the specific case, other airlines on flights to or from NEA airports from July 16, 2020 through the present. Plaintiffs in these actions also seek to enjoin the NEA. JetBlue believes these lawsuits are without merit and has moved to dismiss the claims. For information on legal proceedings related to our previously planned acquisition of Spirit, see Note 12.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Under Topic 820, Fair Value Measurement of the FASB Accounting Standards Codification, (the "Codification"), disclosures are required about how fair value is determined for assets and liabilities and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs as follows: Level 1 - observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - quoted prices in active markets for similar assets and liabilities, and other inputs that are observable directly or indirectly for the asset or liability; or Level 3 - unobservable inputs for the asset or liability, such as discounted cash flow models or valuations. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following is a listing of our assets required to be measured at fair value on a recurring basis and where they are classified within the fair value hierarchy as of June 30, 2024 and December 31, 2023 (in millions): June 30, 2024 Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 995 $ — $ — $ 995 Available-for-sale investment securities — 74 16 90 Aircraft fuel derivatives — 3 — 3 December 31, 2023 Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 724 $ — $ — $ 724 Available-for-sale investment securities — 314 16 330 Aircraft fuel derivatives — 4 — 4 Refe r to Note 3 for fair value information related to our outstanding debt obligations as of June 30, 2024 and December 31, 2023. Cash Equivalents Our cash equivalents include money market se curities and ti me deposits which are readily convertible into cash, have maturities of three months or less when purchased, and are considered to be highly liquid and easily tradable. The money market securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within our fair value hierarchy and recorded within cash and cash equivalents on our consolidated balance sheets. Available-for-Sale Investment Securities Our available-for-sale investment securities include investments such as time deposits, commercial paper, and convertible debt securities. The fair value of time deposits and commercial paper is based on observable inputs in non-active markets, which are therefore classified as Level 2 in the hierarchy. The fair value of convertible debt securities is based on unobservable inputs and is classified as Level 3 in the hierarchy. Aircraft Fuel Derivatives Our aircraft fuel derivatives include call spread options which are not traded on public exchanges. Their fair values are determined using a market approach based on inputs that are readily available from public markets for commodities and energy trading activities; therefore, they are classified as Level 2 inputs. The data inputs are combined into qualitative models and processes to generate forward curves and volatility related to the specific terms of the underlying hedge contracts. Aircraft fuel derivatives are included in prepaid expenses and other within current assets of our consolidated balance sheets. Held-to-Maturity Investment Securities Our held-to-maturity investment securities consist of corporate bonds, which are stated at amortized cost. If the corporate bonds were measured at fair value, they would be classified as Level 2 in the fair value hierarchy, based on quoted prices in active markets for similar securities. We do not intend to sell these investment securities. The carrying value and estimated fair value of our held-to-maturity investment securities were as follows (in millions): June 30, 2024 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value Held-to-maturity investment securities $ 198 $ 195 $ 234 $ 231

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivative Instruments and Risk Management	Financial Derivative Instruments and Risk Management As part of our risk management techniques, we periodically purchase over the counter energy derivative instruments to manage our exposure to the effect of changes in the price of aircraft fuel. Prices for the underlying commodities have historically been highly correlated to aircraft fuel, making derivatives of them effective at providing short-term protection against sharp increases in average fuel prices. We do not hold or issue any derivative financial instruments for trading purposes. Aircraft Fuel Derivatives We attempt to obtain cash flow hedge accounting treatment for each fuel derivative that we enter into. This treatment is provided for under the Derivatives and Hedging topic of the FASB Codification which allows for gains and losses on the effective portion of qualifying hedges to be deferred until the underlying planned aircraft fuel consumption occurs, rather than recognizing the gains and losses on these instruments into earnings during each period they are outstanding. For the effective portion of hedges, when aircraft fuel is consumed and the related derivative contract settles, any gain or loss previously recorded in other comprehensive income (loss) is recognized in aircraft fuel expense. All cash flows related to our fuel hedging derivatives are classified as operating cash flows. Ineffectiveness occurs, in certain circumstances, when the change in the total fair value of the derivative instrument differs from the change in value of our expected future cash outlays for the purchase of aircraft fuel. If a hedge does not qualify for hedge accounting, the periodic changes in its fair value are recognized in other income (expense). Our current approach to fuel hedging is to enter into hedges on a discretionary basis. We view our hedge portfolio as a form of insurance to help mitigate the impact of price volatility and protect us against severe spikes in oil prices, when possible. The following table illustrates the approximate hedged percentages of our projected fuel usage by quarter as of June 30, 2024 related to our outstanding fuel hedging contracts that were designated as cash flow hedges for accounting purposes. Aircraft fuel call option spread agreements Third quarter 2024 20 % Fourth quarter 2024 5 % The table below reflects quantitative information related to our derivative instruments and where these amounts are recorded in our financial statements (dollar amounts in millions): June 30, 2024 December 31, 2023 Fuel derivatives Asset fair value recorded in prepaid expenses and other current assets (1) $ 3 $ 4 Longest remaining term (months) 3 3 Hedged volume (barrels, in thousands) 1,272 2,706 Estimated amount of existing gains (losses) expected to be reclassified into earnings in the next 12 months $ 2 $ (3) (1) Gross asset or liability of each contract prior to consideration of offsetting positions with each counterparty and prior to impact of collateral paid.

The amount of such credit exposure is generally the fair value of our outstanding contracts for which we are in a receivable position. To manage credit risks we select counterparties based on credit assessments, limit our overall exposure to any single counterparty, and monitor the market position with each counterparty. Some of our agreements require cash deposits from either JetBlue or our counterparty if market risk exposure exceeds a specified threshold amount. We have master netting arrangements with our counterparties allowing us the right of offset to mitigate credit risk in derivative transactions. The financial derivative instrument agreements we have with our counterparties may require us to fund all, or a portion of, outstanding loss positions related to these contracts prior to their scheduled maturities. The amount of collateral posted, if any, is periodically adjusted based on the fair value of the hedge contracts. Our policy is to offset the liabilities represented by these contracts with any cash collateral paid to the counterparties. There were no offsetting derivative instruments as of June 30, 2024 and December 31, 2023.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Termination of Merger Agreement with Spirit	Termination of Merger Agreement with Spirit The Merger Agreement As previously disclosed, on July 28, 2022, JetBlue entered into the Merger Agreement with Spirit and Sundown Acquisition Corp., formerly a Delaware corporation and a direct wholly owned subsidiary of JetBlue ("Merger Sub"), pursuant to which and subject to the terms and conditions therein, Merger Sub would merge with and into Spirit, with Spirit continuing as the surviving corporation (the "Merger"). On March 1, 2024, JetBlue, Spirit and Merger Sub entered into a Termination Agreement (the "Termination Agreement"), pursuant to which the parties agreed to terminate the Merger Agreement, effective immediately, subject to limited exceptions related to JetBlue’s previously agreed indemnification obligations. Pursuant to the Termination Agreement, JetBlue agreed to pay the $69 million breakup fee on March 5, 2024, which was recorded in special items on the consolidated statement of operations. The parties also agreed to release each other from claims, demands, damages, actions, causes of action and liability relating to or arising out of the Merger Agreement and the transactions contemplated therein or thereby. In accordance with the terms of the Merger Agreement, on a monthly basis between January 2023 and February 2024, JetBlue paid to the holders of record of outstanding Spirit shares an amount in cash equal to $0.10 per Spirit share (such amount, the "Additional Prepayment Amount", and each such monthly payment, an "Additional Prepayment"). In 2024, JetBlue made an aggregate of $22 million in Additional Prepayments to Spirit shareholders resulting in a total prepayment of $425 million. These Additional Prepayments were written off in March 2024, in addition to the $25 million reimbursement payment to Spirit in connection with the Frontier transaction costs as a result of the termination of the Merger Agreement. The write off is recorded in special items on the consolidated statement of operations. In March 2024, the Company recorded a valuation allowance of $134 million related to the tax impact of the Spirit transaction costs. Refer to Note 3 for further detail of the $3.5 billion Senior Secured Bridge Facility commitment to fund the purchase of Spirit, which was terminated concurrently with the termination of the Merger Agreement. Legal Proceedings Related to the Merger As previously disclosed, in March 2023, the U.S. Department of Justice, along with the Attorneys General of six states and the District of Columbia, filed suit in the U.S. District Court for the District of Massachusetts against JetBlue and Spirit, seeking a permanent injunction preventing the Merger (the "Government Merger Lawsuit"). The trial commenced on October 31, 2023 and on January 17, 2024, the Court issued its Final Judgment and Order granting the plaintiffs' request for a permanent injunction of the Merger. On January 19, 2024, JetBlue and Spirit filed a Notice of Appeal with respect to the January 17, 2024 Final Judgment and Order and the Court’s corresponding January 16, 2024 Findings of Facts and Conclusion of Law, which the parties then moved to dismiss following their entrance into the Termination Agreement. On March 5, 2024, the Court approved JetBlue and Spirit's voluntary dismissal of the appeal.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation JetBlue Airways Corporation ("JetBlue") provides air transportation services across the United States, the Caribbean, Latin America, Canada, and Europe. Our condensed consolidated financial statements include the accounts of JetBlue and our subsidiaries which are collectively referred to as "we" or the "Company." All majority-owned subsidiaries are consolidated on a line-by-line basis, with all intercompany transactions and balances being eliminated. These condensed consolidated financial statements and related notes should be read in conjunction with our 2023 audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Form 10-K"). These condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC"). In our opinion, they reflect all adjustments, including normal recurring items, that are necessary to present fairly the results for interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been condensed or omitted as permitted by such rules and regulations; however, we believe that the disclosures included herein are adequate to make the information presented not misleading.
Reclassifications	We have reclassified certain prior periods to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.
Cash equivalents	Cash Equivalents Our cash equivalents include money market se curities and ti
Investment in Securities	Available-for-Sale Investment Securities Our available-for-sale investment securities include investments such as time deposits, commercial paper, and convertible debt securities. The fair value of time deposits and commercial paper is based on observable inputs in non-active markets, which are therefore classified as Level 2 in the hierarchy. The fair value of convertible debt securities is based on unobservable inputs and is classified as Level 3 in the hierarchy. Aircraft Fuel Derivatives Our aircraft fuel derivatives include call spread options which are not traded on public exchanges. Their fair values are determined using a market approach based on inputs that are readily available from public markets for commodities and energy trading activities; therefore, they are classified as Level 2 inputs. The data inputs are combined into qualitative models and processes to generate forward curves and volatility related to the specific terms of the underlying hedge contracts. Aircraft fuel derivatives are included in prepaid expenses and other within current assets of our consolidated balance sheets. Held-to-Maturity Investment Securities Our held-to-maturity investment securities consist of corporate bonds, which are stated at amortized cost. If the corporate bonds were measured at fair value, they would be classified as Level 2 in the fair value hierarchy, based on quoted prices in active markets for similar securities.
