Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Flight Equipment Commitments As of June 30, 2020, our firm aircraft orders consisted of 76 Airbus A321neo aircraft and 70 Airbus A220 aircraft, all scheduled for delivery through 2026. Committed expenditures for these aircraft and related flight equipment, including estimated amounts for contractual price escalations and predelivery deposits, is approximately $0.4 billion for the remainder of 2020, $1.1 billion in 2021, $0.9 billion in 2022, $1.7 billion in 2023, $1.8 billion in 2024, and $2.0 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. We continue to work with our business partners, including Airbus, to evaluate the potential financial and operational impact of these announcements on our aircraft deliveries. The continued imposition of the tariff could substantially increase the cost of new Airbus aircraft and parts. Other Commitments 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, 2020, we had approximately $25 million in assets serving as collateral for letters of credit relating to a certain number of our leases. These are included in restricted cash and expire at the end of the related lease terms. Additionally, we had approximately $25 million pledged related to our workers' compensation insurance policies and other business partner agreements, which will expire according to the terms of the related policies or agreements. In April 2014, ALPA was certified by the National Mediation Board, or NMB, as the representative body for JetBlue pilots after winning a representation election. We reached a final agreement for our first collective bargaining agreement which was ratified by the pilots in July 2018. The agreement is a four-year, renewable contract, which became effective August 1, 2018 and included compensation, benefits, work rules, and other policies. Amid the COVID-19 pandemic, we have signed a letter of agreement with ALPA that will avoid involuntary furloughs of our pilots until May 1, 2021 in exchange for short-term changes to the collective bargaining agreement. In April 2018, JetBlue inflight crewmembers elected to be solely represented by the Transport Workers Union of America, or TWU. The NMB certified the TWU as the representative body for JetBlue inflight crewmembers and we are working with the TWU to reach a collective bargaining agreement. Except as noted above, our crewmembers do not have third party representation. 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 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.
