These condensed consolidated financial statements are unaudited and have been prepared by us following the rules and regulations of the U.S. Securities and Exchange Commission, or 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, or GAAP, have been condensed or omitted as permitted by such rules and regulations; however, we believe that the disclosures are adequate to make the information presented not misleading.

Due to the ongoing impacts from the coronavirus ("COVID-19") pandemic, seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, and other factors, our operating results for the periods presented herein are not necessarily indicative of the results that may be expected for other interim periods or the entire fiscal year.

Upon conversion, the notes will be settled in cash up to the aggregate principal amount of the notes to be converted and, at our election, in shares of our common stock, cash or a combination of cash and shares of our common stock in respect of the remainder, if any, of our conversion obligation.

We may, at our option, redeem any of the notes for cash at a redemption price of 100% of their principal amount, plus accrued and unpaid interest at any time on or after April 1, 2024 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which we provide notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which we provide a notice of redemption to the holders.

Borrowings under the Credit and Guaranty Agreement bear interest at a variable rate equal to LIBOR, plus a margin. The Credit and Guaranty Agreement was previouslyare secured by Slots at John F. Kennedy International Airport, LaGuardia Airport, and Reagan National Airport, as well as certain other assets. Slots are rights to take-off or land at a specific airport during a specific time period during the day and a means by which airport capacity and congestion can be managed. On May 29, 2020, we exercised our pre-existing right and removed the Slots from the collateral pool to the facility. In exchange for the Slots, we added unencumbered aircraft, simulators, and certain other assets as permitted thereunder.assets. The Credit and Guaranty Agreement includes covenants that require us to maintain certain minimum balances in unrestricted cash, cash equivalents, and unused commitments available under revolving credit facilities.

We sponsor a retirement savings 401(k) defined contribution plan, or the Plan, covering all of our crewmembers where we match 100% of our crewmember contributions up to 5% of their eligible wages.

As of March 31, 2021,2022, our firm aircraft orders consisted of 6964 Airbus A321neo aircraft and 6992 Airbus A220 aircraft, scheduled for delivery through 2027. Committed expenditures for these aircraft and related flight equipment, including estimated amounts for contractual price escalations and predelivery deposits as of March 31, 20212022 is approximately $0.7 billion for the remainder of 2021, $0.8 billion in 2022, $1.6 billion in 2023, $1.8$2.0 billion in 2024, $1.2$1.7 billion in 2025, $1.4 billion in 2026, and $1.6$1.0 billion thereafter.

In October 2019, the Office of the U.S. Trade Representative announced a 10% tariff on new commercial aircraft and related parts imported from certain European Union member states, which include aircraft and other parts we are already contractually obligated to purchase, including those noted above. The U.S. Trade Representative increased the tariff to 15% effective March 2020. In March 2021, the U.S. Trade Representative announced a four-month suspension of the tariff.tariff that was followed by an announcement in June 2021 that the suspension will be extended for five years. We continue to work with our business partners, including Airbus, to evaluate the potential financial and operational impact of these announcements on our future aircraft deliveries, including after the suspension is lifted. The continued imposition of thethis or any tariff could substantially increase the cost of new Airbus aircraft and parts.

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.

In April 2021, ALPA, on behalf of the JetBlue pilot group, filed a grievance relating to the Northeast Alliance Agreement ("NEA"), an expanded codeshare and marketing alliance between JetBlue and American Airlines, Inc. ("American") at least October 1,4 Northeast airports. ALPA claims that in entering the NEA, JetBlue violated certain scope clauses as contained in the pilots’ ALPA collective bargaining agreement. A final mediation session concluded in September 2021 and in exchange for short-termJanuary 2022, the parties submitted final written briefs to the System Board. Shortly after submission of the briefs, the parties agreed to enter into non-binding mediation with the assistance of the arbitrator with a temporary hold on a System Board decision. As a result of the mediation process, the parties agreed to certain changes to the collective bargaining agreement.

We enter into individual employment agreements with each of our non-unionized FAA-licensed crewmembers, which include dispatchers, technicians, and inspectors, as well as 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 Transport Workers Unionend of America, or TWU. The National Mediation Board, or NMB, certified the TWU asrelevant term. Pursuant to these agreements, these crewmembers can only be terminated for cause. In the representative body for JetBlue inflight crewmembers. In November 2020,event of a downturn in our inflightbusiness that would require a reduction in work hours, we are obligated to pay these crewmembers voteda guaranteed level of income and to reject the tentative collective bargaining agreement between JetBlue and the TWU. We are currently working with the TWU to determine next steps.

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 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 consolidated results of operations, liquidity, or financial condition.

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.
