Dec. 31, 2019
Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation JetBlue provides air transportation services across the United States, the Caribbean, and Latin America. Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, and include the accounts of JetBlue and our subsidiaries. All majority-owned subsidiaries are consolidated with all intercompany transactions and balances being eliminated.
Use of Estimates | Use of Estimates The preparation of our consolidated financial statements and accompanying notes in conformity with GAAP requires us to make certain estimates and assumptions. Actual results could differ from those estimates.
Fair Value | Fair Value The Fair Value Measurements and Disclosures topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification®, or Codification, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. This topic clarifies that fair value is 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. The topic also requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs. Refer to Note 14 to our consolidated financial statements for more information.
Cash and Cash Equivalents | Cash and Cash Equivalents Our cash and cash equivalents include short-term, highly liquid investments which are readily convertible into cash. These investments include money market securities, commercial paper, and time deposits with maturities of three months or less when purchased. Cash equivalents Our cash equivalents include money market securities, commercial paper, and time deposits which are readily convertible into cash, have maturities of 90 days 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. The fair values of remaining instruments are based on observable inputs in non-active markets, which are therefore classified as Level 2 in the hierarchy.
Restricted Cash | Restricted Cash Restricted cash primarily consists of security deposits, funds held in escrow for estimated workers’ compensation obligations, and performance bonds for aircraft and facility leases.
Accounts and Other Receivables | Accounts and Other Receivables Accounts and other receivables are carried at cost. They primarily consist of amounts due from credit card companies associated with sales of tickets for future travel. We estimate an allowance for doubtful accounts based on known troubled accounts, if any, and historical experience of losses incurred.
Investment Securities | Investment Securities Investment securities consist of available-for-sale investment securities and held-to-maturity investment securities. When sold, we use a specific identification method to determine the cost of the securities. Available-for-sale investment securities Our available-for-sale investment securities include highly liquid investments such as time deposits, U.S. Treasury bills with maturities between three and twelve months, commercial paper, and convertible debt securities which are stated at fair value. Held-to-maturity investment securities Our held-to-maturity investments consist of investment-grade interest bearing instruments, such as corporate bonds and U.S. Treasury notes, which are stated at amortized cost. We do not intend to sell these investment securities and the contractual maturities are not greater than 24 months. Those with maturities less than twelve months are included in short-term investments on our consolidated balance sheets. Those with remaining maturities in excess of twelve months are included in long-term investments on our consolidated balance sheets. We did not record any material gains or losses on these securities during the years ended December 31, 2019, 2018 or 2017. The estimated fair value of these investments approximated their carrying value as of December 31, 2019 and 2018. The carrying values of investment securities consisted of the following at December 31, 2019 and 2018 (in millions):
|  | December 31, 2019 |  | December 31, 2018
Available-for-sale securities |  |  |  |
Time deposits |  | $ | 325 |  |  | $ | 190 |
U.S. Treasury |  | — |  |  | 39 |
Commercial paper |  | 20 |  |  | — |
Debt securities |  | 6 |  |  | 7 |
Total available-for-sale securities |  | 351 |  |  | 236 |
Held-to-maturity securities |  |  |  |
U.S. Treasury |  | — |  |  | 180 |
Corporate bonds |  | 21 |  |  | — |
Total held-to-maturity securities |  | 21 |  |  | 180 |
Total investment securities |  | $ | 372 |  |  | $ | 416 |
Available-for-sale investment securities Our available-for-sale investment securities include investments such as time deposits, U.S. treasury bills, commercial paper, and convertible debt securities. The U.S. treasury bills are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within the fair value hierarchy. The fair values of remaining instruments are based on observable inputs in non-active markets, which are therefore classified as Level 2 in the hierarchy. We did not record any material gains or losses on these securities during the years ended December 31, 2019, 2018, and 2017.
Schedule of Equity Method Investments [Line Items] |
Equity Method Investments [Policy Text Block] | Equity Method Investments Investments in which we can exercise significant influence are accounted for using the equity method in accordance with Topic 323, Investments - Equity Method and Joint Ventures of the Codification. The carrying amount of our equity method investments, which is recorded within other assets on our consolidated balance sheets, was $38 million and $11 million as of December 31, 2019 and 2018, respectively. In September 2019, we recognized a gain of $15 million on one of our equity method investments
Derivative Instruments | Derivative Instruments Our derivative instruments include fuel hedge contracts, such as jet fuel call options and call option spreads, which are stated at fair value, net of any collateral postings. Derivative instruments are included in other current assets and other current liabilities on our consolidated balance sheets. Refer to Note 13 to our consolidated financial statements for more information. Aircraft fuel derivatives Our aircraft fuel derivatives include call option spreads and call 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 quantitative models and processes to generate forward curves and volatilities related to the specific terms of the underlying hedge contracts.
Inventories | Inventories Inventories consist of expendable aircraft spare parts and supplies that are stated at average cost, as well as aircraft fuel that is accounted for on a first-in, first-out basis. These items are expensed when used or consumed. An allowance for obsolescence on aircraft spare parts is provided over the remaining useful life of the related aircraft fleet.
Property and Equipment | Property and Equipment We record our property and equipment at cost and depreciate these assets on a straight-line basis over their estimated useful lives to their estimated residual values. We capitalize additions, modifications enhancing the operating performance of our assets, and the interest related to predelivery deposits used to acquire new aircraft and the construction of our facilities. Estimated useful lives and residual values for our property and equipment are as follows:
Property and Equipment Type |  | Estimated Useful Life |  | Residual Value
Aircraft |  | 25 years |  | 20 | %
Inflight entertainment systems |  | 5-10 years |  | 0 | %
Aircraft parts |  | Fleet life |  | 10 | %
Flight equipment leasehold improvements |  | Lower of lease term or economic life |  | 0 | %
Ground property and equipment |  | 2-10 years |  | 0 | %
Leasehold improvements—other |  | Lower of lease term or economic life |  | 0 | %
Buildings on leased land |  | Lease term |  | 0 | %
Property under finance leases is initially recorded at an amount equal to the present value of future minimum lease payments which is computed on the basis of our incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under finance leases is on a straight-line basis over the expected useful life to their estimated residual values and is included in depreciation and amortization expense. We record impairment losses on long-lived assets used in operations when events and circumstances indicate the assets may be impaired and the undiscounted future cash flows estimated to be generated by the assets are less than the assets’ net book value. If impairment occurs, the loss is measured by comparing the fair value of the asset to its carrying amount.
Software | Software We capitalize certain costs related to the acquisition and development of computer software. We amortize these costs using the straight-line method over the estimated useful life of the software, which is generally five years. The net book value of computer software, which is included in other assets on our consolidated balance sheets, was $102 million and $96 million as of December 31, 2019 and 2018, respectively. Amortization expense related to computer software was $52 million, $46 million and $41 million for the years ended December 31, 2019, 2018, and 2017, respectively. As of December 31, 2019, amortization expense related to computer software is expected to be approximately $35 million in 2020, $26 million in 2021, $22 million in 2022, $15 million in 2023, and $4 million in 2024.
Intangible Assets | Intangible Assets Our intangible assets consist primarily of acquired take-off and landing slots, or Slots, at certain domestic airports. Slots are the rights to take-off or land at a specific airport during a specific time period of the day and are a means by which airport capacity and congestion can be managed. We account for Slots at High Density Airports, including Reagan National Airport in Washington, D.C., LaGuardia Airport, and JFK Airport, both in New York City, as indefinite life intangible assets which result in no amortization expense. We evaluate our intangible assets for impairment at least annually or when events and circumstances indicate they may be impaired. Indicators include operating or cash flow losses as well as various market factors to determine if events and circumstances could reasonably have affected the fair value. As of December 31, 2019 and 2018, our intangible assets for Slots at High Density Airports with indefinite lives were $139 million.
Passenger Revenues | Passenger Revenue Ticket sales and the fees collected for related ancillary services are initially deferred in air traffic liability. Air traffic liability represents tickets sold but not yet flown, credits which can be used for future travel, and a portion of the liability related to our TrueBlue® loyalty program. We allocate the transaction price to each performance obligation identified in a passenger ticket on a relative standalone basis. Passenger revenue, including certain ancillary fees directly related to passenger tickets, is recognized when the transportation is provided. Taxes that we are required to collect from our customers, including foreign and U.S. federal transportation taxes, security taxes, and airport facility charges, are excluded from passenger revenue. Those taxes and fees are recorded as a liability upon collection and are relieved from the liability upon remittance to the applicable governmental agency. The majority of the tickets sold are non-refundable. Non-refundable fares may be canceled prior to the scheduled departure date for a credit for future travel. Refundable fares may be canceled at any time prior to the scheduled departure date. Failure to cancel a refundable fare prior to departure will result in the cancellation of the original ticket and an issuance of a credit for future travel. Passenger credits can be used for future travel up to a year from the date of issuance. Passenger breakage revenue from unused tickets and passenger credits will be recognized in proportion to flown revenue based on estimates of expected expiration when the likelihood of the customer exercising his or her remaining rights becomes remote. Breakage revenue consists of non-refundable tickets that remain unused past the departure date, have continued validity, and are expected to ultimately expire unused, as well as passenger credits that are not expected to be redeemed prior to expiration. JetBlue uses estimates based on historical experience of expired tickets and credits and considers other factors that could impact future expiration patterns of tickets and credits. Tickets which do not have continued validity past the departure date are recognized as revenue after the scheduled departure date has lapsed. Passenger ticket costs primarily include credit card fees, commissions paid, and global distribution systems booking fees. Costs are allocated entirely to the purchased travel services and are capitalized until recognized when travel services are provided to the customer.
Loyalty Program | Loyalty Program Customers may earn points under our customer loyalty program, TrueBlue®, based on the fare paid and fare product purchased for a flight. Customers can also earn points through business partners such as credit card companies, hotels, car rental companies, and our participating airline partners. Points Earned From a Ticket Purchase. When a TrueBlue® member travels, we recognize a portion of the fare as revenue and defer in air traffic liabilities the portion that represents the value of the points net of spoilage, or breakage. We allocate the transaction price to each performance obligation on a relative standalone basis. We determine the standalone selling price of TrueBlue® points issued using the redemption value approach. To maximize the use of observable inputs, we utilize the actual ticket value of the tickets purchased with TrueBlue® points. The liability is relieved and passenger revenue is recognized when the points are redeemed and the free travel is provided. Points Sold to TrueBlue® Partners. Our most significant contract to sell TrueBlue® points is with our co-branded credit card partner. Co-branded credit card partnerships have the following identified performance obligations: air transportation; use of the JetBlue brand name and access to our frequent flyer customer lists; advertising; and other airline benefits. In determining the estimated selling price, JetBlue considered multiple inputs, methods and assumptions, including: discounted cash flows; estimated redemption value, net of fulfillment discount; points expected to be awarded and redeemed; estimated annual spending by cardholders; estimated annual royalty for use of JetBlue's frequent flyer customer lists; and estimated utilization of other airline benefits. Payments are typically due monthly based on the volume of points sold during the period, and the terms of our marketing contracts are generally from one to seven years. The overall consideration received is allocated to each performance obligation based on their standalone relative selling prices. The air transportation element is deferred and recognized as passenger revenue when the points are utilized. The other elements are recognized as other revenue when the performance obligation related to those services are satisfied, which is generally the same period as when consideration is received from the participating company. Amounts allocated to the air transportation element which are initially deferred include a portion that are expected to be redeemed during the following twelve months (classified as a component of Air traffic liability), and a portion that are not expected to be redeemed during the following twelve months (classified as Air traffic liability - loyalty non-current). We periodically update this analysis and adjust the split between current and non-current liabilities as appropriate. Points earned by TrueBlue® members never expire. TrueBlue® members can pool points between small groups of people, branded as Points Pooling™. Breakage is estimated using historical redemption patterns to determine a breakage rate. Breakage rates used to estimate breakage revenue are evaluated annually. Changes to breakage estimates impact revenue recognition prospectively.
Airframe and Engine Maintenance and Repair | Airframe and Engine Maintenance and Repair Regular airframe maintenance for owned and leased flight equipment is charged to expense as incurred unless covered by a third-party long-term flight hour service agreement. We have separate service agreements in place covering scheduled and unscheduled repairs of certain airframe line replacement unit components as well as the engines in our fleet. Certain of these agreements, whose original terms generally range from 10 to 15 years, require monthly payments at rates based either on the number of cycles each aircraft was operated during each month or the number of flight hours each engine was operated during each month, subject to annual escalations. These power by the hour agreements transfer certain risks, including cost risks, to the third-party service providers. They generally fix the amount we pay per flight hour or number of cycles in exchange for maintenance and repairs under a predefined maintenance program, which are representative of the time and materials that would be consumed. These costs are expensed as the related flight hours or cycles are incurred.
Advertising Costs | Advertising Costs Advertising costs, which are included in sales and marketing, are expensed as incurred. Advertising expense was $66 million in 2019, $72 million in 2018 and $66 million in 2017.
Share-Based Compensation | Share-Based Compensation We record compensation expense for share-based awards based on the grant date fair value of those awards. Share-based compensation expense includes an estimate for pre-vesting forfeitures and is recognized over the requisite service periods of the awards on a straight-line basis.
Income Taxes | Income Taxes We account for income taxes utilizing the liability method. Deferred income taxes are recognized for the tax consequences of temporary differences between the tax and financial statement reporting bases of assets and liabilities. A valuation allowance for deferred tax assets is provided unless realizability is judged by us to be more likely than not. Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.
New Accounting Standards | Recently Issued Accounting Standards New accounting rules and disclosure requirements can impact our financial results and the comparability of our financial statements. The authoritative literature which has recently been issued and that we believe will impact our consolidated financial statements is described below. There are also several new proposals under development. If and when enacted, these proposals may have a significant impact on our financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The update requires the use of an "expected loss" model on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. For trade receivables, loans, and held-to-maturity debt securities, entities will be required to estimate lifetime expected credit losses. For available-for-sale debt securities, entities will be required to recognize an allowance for credit losses rather than a reduction to the carrying value of the asset. The new standard is effective for us on January 1, 2020 and we are required to adopt its provisions using a modified retrospective transition approach by recording a cumulative effect adjustment in retained earnings as of the beginning of the year of adoption. We have substantially completed our assessment of the new standard and do not expect its adoption to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The update eliminates, adds, and modifies certain disclosure requirements for fair value measurements. The new standard is effective for us on January 1, 2020. We have substantially completed our assessment of the new standard and do not expect its adoption to have a significant impact on our consolidated financial statement disclosures. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The update eliminates, clarifies, and modifies certain guidance related to the accounting for income taxes. ASU 2019-12 is effective for annual reporting periods beginning after December 15, 2020, with early adoption permitted. We are still evaluating the full impact of adopting the amendments on our consolidated financial statements. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) of the Codification, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; ASU 2018-11, Targeted Improvements; ASU 2018-20, Narrow-Scope Improvements for Lessors; and ASU 2019-01, Leases (Topic 842): Codification Improvements. Under the new standard, a lessee will recognize liabilities on the balance sheet, initially measured at the present value of the lease payments, and right-of-use (ROU) assets representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less at the commencement date, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. The new standard also eliminates the build-to-suit lease accounting guidance which results in the derecognition of build-to-suit assets and liabilities that remained on the balance sheet after the end of the construction period. We adopted the requirements of ASU 2016-02 as of January 1, 2019, utilizing the modified retrospective method of transition for all leases existing at or commencing after the date of initial application. We recorded a $58 million cumulative adjustment to retained earnings as of January 1, 2017, the beginning of the retrospective reporting period, for the impact of the new accounting standard. The adjustments to retained earnings were driven principally by the derecognition of our existing assets constructed for others and construction obligation related to our Terminal 5 (T5) build-to-suit project at John F. Kennedy International Airport in New York. We elected to use the package of transition provisions available for expired or existing contracts, which allowed us to carryforward our historical assessment of whether contracts are or contain leases, lease classification, and initial direct costs. Refer to Note 4 to our consolidated financial statements for more information. In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The update provides guidance for determining if a cloud computing arrangement is within the scope of internal-use software guidance, and would require capitalization of certain implementation costs. ASU 2018-15 is effective for annual reporting periods beginning after December 15, 2019, with early adoption permitted. We adopted the requirements of ASU 2018-15 on April 1, 2019 using the prospective transition method. The adoption of ASU 2018-15 did not have a material impact on our consolidated financial statements.
