Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation JetBlue Airways Corporation, or JetBlue, provides air transportation services across the United States, the Caribbean and Latin America. 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 2016 audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 , or our 2016 Form 10-K. These condensed consolidated financial statements are unaudited and have been prepared by us following the rules and regulations of the 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 U.S., 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. 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. Investment securities Investment securities consist of available-for-sale investment securities and held-to-maturity investment securities. We use a specific identification method to determine the cost of the securities when they are sold. Held-to-maturity investment securities. The contractual maturities of the corporate bonds we held as of June 30, 2017 were not greater than 24 months. We did not record any significant gains or losses on these securities during the three and six months ended June 30, 2017 or 2016 . The estimated fair value of these investments approximated their carrying value as of June 30, 2017 and December 31, 2016 , respectively. The carrying values of investment securities consisted of the following at June 30, 2017 and December 31, 2016 (in millions): June 30, 2017 December 31, 2016 Available-for-sale securities Time deposits $ 150 $ 160 Commercial paper 45 60 Treasury bills 12 115 Total available-for-sale securities 207 335 Held-to-maturity securities Treasury notes $ 201 $ 283 Corporate bonds 62 10 Total held-to-maturity securities 263 293 Total investment securities $ 470 $ 628 Recent Accounting Pronouncements During the first quarter of 2017, we adopted Accounting Standards Update, or ASU, 2015-17, Income Taxes, Balance Sheet Classification of Deferred Taxes topic of the FASB Codification, or Codification. This standard requires all deferred tax assets and liabilities to be classified as non-current on the balance sheet instead of separating deferred taxes into current and non-current amounts. In addition, valuation allowance allocations between current and non-current deferred tax assets are no longer required because those allowances also will be classified as non-current. Our condensed consolidated balance sheet as of December 31, 2016 reflects retrospective application. As a result of the adoption, $9 million of deferred tax liabilities previously included within other accrued liabilities and $164 million of deferred tax assets previously included within current assets have been moved to long-term liabilities on our December 31, 2016 balance sheet. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . Under ASU 2016-02, a lessee will recognize liabilities for lease payments and right-of-use assets representing its right to use the underlying asset for the lease term. While we are still evaluating the full impact of adopting the amendments on our consolidated financial statements and disclosures, we have determined that it will impact our accounting for aircraft and other leases. The amendments are effective for fiscal years beginning after December 15, 2018 and include interim periods within those fiscal years. Early adoption is permitted, and companies are required to use a modified retrospective approach at the earliest period presented. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash . The amendments clarified how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. The amendments are effective for fiscal years beginning after December 15, 2017 and include interim periods within those years. Early adoption is permitted. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which supersedes existing revenue recognition guidance. Under the new standard, a company will recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. The standard allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year to interim and annual reporting periods beginning after December 15, 2017 and permitted early adoption of the standard, but not prior to December 15, 2016. While we are evaluating the full impact of ASU 2014-09 on our consolidated financial statements, we have determined that it will impact our loyalty program accounting. JetBlue will no longer be allowed to use the incremental cost method when recording the financial impact of TrueBlue® points earned on qualifying JetBlue purchases. We will be required to re-value our liability with a relative fair value approach, which is anticipated to significantly increase the related liability. In addition, the standard will likely result in a change in the timing and classification of our revenue recognition for certain ancillary fees directly related to passenger revenue tickets, as these services are no longer likely to be considered distinct performance obligations. Fees associated with these services are likely to be recognized as of the date of travel, not when assessed to the customer, and classified as passenger revenue. JetBlue currently anticipates adopting ASU 2014-09 effective January 1, 2018 using the full retrospective method, however, this decision is not final and is subject to the completion of our analysis of the standard. We will continue our evaluation of ASU 2014-09 through the date of adoption.

Debt Disclosure [Abstract]
Long-term Debt, Short-term Borrowings, and Capital Lease Obligations	Long Term Debt, Short Term Borrowings, and Capital Lease Obligations During the six months ended June 30, 2017 , we made scheduled principal payments of $84 million on our outstanding long-term debt and capital lease obligations. We have pledged aircraft, engines, other equipment and facilities with a net book value of $2.4 billion at June 30, 2017 as security under various loan agreements. As of June 30, 2017 , we owned, free of encumbrance, 74 Airbus A320 aircraft, 33 Airbus A321 aircraft and 37 spare engines. At June 30, 2017 , scheduled maturities of all of our long-term debt and capital lease obligations were $106 million for the remainder of 2017 , $193 million in 2018 , $215 million in 2019 , $179 million in 2020 , $164 million in 2021 and $448 million thereafter. The carrying amounts and estimated fair values of our long-term debt at June 30, 2017 and December 31, 2016 were as follows (in millions): June 30, 2017 December 31, 2016 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Public Debt Fixed rate special facility bonds, due through 2036 $ 42 $ 46 $ 42 $ 45 Non-Public Debt Fixed rate enhanced equipment notes, due through 2023 $ 180 $ 189 $ 188 $ 197 Floating rate equipment notes, due through 2025 162 167 171 179 Fixed rate equipment notes, due through 2026 789 851 843 915 Total (1) $ 1,173 $ 1,253 $ 1,244 $ 1,336 (1) Total excludes capital lease obligations of $132 million for June 30, 2017 and $140 million for December 31, 2016. The estimated fair values of our publicly held long-term debt are classified as Level 2 in the fair value hierarchy. The fair values of our enhanced equipment notes and our special facility bonds were based on quoted market prices in markets with low trading volumes. The fair value of our non-public debt was 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. We have financed certain aircraft with Enhanced Equipment Trust Certificates, or EETCs, as 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, or VIE, as defined in the Consolidations topic of the Codification, and must be considered for consolidation in our condensed consolidated 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 credit worthiness of our debt obligation through certain bankruptcy protection provisions, liquidity facilities and 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 condensed consolidated financial statements. Short-term Borrowings Citibank Line of Credit As of June 30, 2017, we had an Amended and Restated Credit and Guaranty Agreement (the "Amended and Restated Facility") with Citibank, N.A. as the administrative agent for up to approximately $425 million . The term of the Amended and Restated Facility runs through April 6, 2021. Borrowings under the Amended and Restated Facility bear interest at a variable rate equal to LIBOR, plus a margin and are 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 are a means by which airport capacity and congestion can be managed. The Amended and Restated Facility includes covenants that require us to maintain certain minimum balances in unrestricted cash, cash equivalents, and unused commitments available under all revolving credit facilities. In addition, the covenants restrict our ability to, among other things, dispose of certain collateral, or merge, consolidate, or sell assets. As of and for the periods ended June 30, 2017 and December 31, 2016 , we did not have a balance outstanding or borrowings under this line of credit. 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, plus a margin . As of and for the periods ended June 30, 2017 and December 31, 2016, we did not have a balance outstanding under this line of credit.

The adoption of this standard resulted in the recognition of 8 million of excess tax benefits to the income tax provision for the year ended December 31, 2016. Net income and shares outstanding data for the three months and six months ended June 30, 2016 are presented as if the ASU was adopted at the beginning of 2016. We have no convertible debt outstanding as of June 30, 2017 .

Retirement Benefits [Abstract]
Compensation and Employee Benefit Plans [Text Block]	Crewmember Retirement Plan and Profit Sharing We sponsor a retirement savings 401(k) defined contribution plan, or the Plan, covering all of our employees, who we refer to as Crewmembers, where we match 100% of our Crewmembers' contributions up to 5% of their eligible wages. The contributions vest over 5 years and are measured from a Crewmember's hire date. Crewmembers are immediately vested in their voluntary contributions. Another component of the Plan is a Company discretionary contribution of 5% of eligible non-management Crewmember compensation, which we refer to as Retirement Plus. Retirement Plus contributions vest over 3 years and are measured from a Crewmember's hire date. For years of service prior to 2017, our non-management Crewmembers were also eligible to receive profit sharing, calculated as 15% of adjusted pre-tax income before profit sharing and special items with the result reduced by Retirement Plus contributions. Eligible non-management Crewmembers may elect to have their profit sharing contributed directly to the Plan. Beginning with 2017, non-management Crewmembers are eligible to receive profit sharing, calculated as 10% of adjusted pre-tax income before profit sharing and special items up to a pre-tax margin of 18% with the result reduced by Retirement Plus contributions. If JetBlue's resulting pre-tax margin exceeds 18% , non-management Crewmembers will receive 20% profit sharing above an 18% pre-tax margin. Certain Federal Aviation Administration, or FAA, licensed Crewmembers receive an additional contribution of 3% of eligible compensation, which we refer to as Retirement Advantage. Total 401(k) company match, Retirement Plus, profit sharing and Retirement Advantage expensed for the three months ended June 30, 2017 and 2016 was $52 million and $66 million , respectively, while the total amount expensed for the Plan for the six months ended June 30, 2017 and 2016 was $94 million and $148 million , respectively.

Other Commitments As part of the 2014 sale of LiveTV, LLC, or LiveTV, formerly a wholly owned subsidiary of JetBlue, to Thales Holding Corporation a $3 million liability relating to Airfone, a former subsidiary of LiveTV, was assigned to JetBlue under the purchase agreement with Thales. Separately, prior to the sale of LiveTV, JetBlue had an agreement with ViaSat Inc. through 2020 relating to in-flight broadband connectivity technology on our aircraft. That agreement stipulated a $20 million minimum commitment for the connectivity service and a $25 million minimum commitment for the related hardware and software purchase. As part of the sale of LiveTV, these commitments to ViaSat Inc. were assigned to LiveTV and JetBlue entered into two new service agreements with LiveTV pursuant to which LiveTV will provide in-flight entertainment and connectivity services to JetBlue for a minimum of seven years. As of June 30, 2017 , we had approximately $29 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 $27 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. Legal Matters Occasionally we are involved in various claims, lawsuits, regulatory examinations, investigations and other legal matters 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 financial condition or results of operations.

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 and enter into fixed forward price agreements, or FFPs, 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 also periodically enter into jet fuel basis swaps for the differential between heating oil and jet fuel, to further limit the variability in fuel prices at various locations. 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 Codification which allows for gains and losses on the effective portion of qualifying hedges to be deferred until the underlying planned jet fuel consumption occurs, rather than recognizing the gains and losses on these instruments into earnings during each period they are outstanding. The effective portion of realized fuel hedging derivative gains and losses is recognized in aircraft fuel expense in the period during which the underlying fuel is consumed. Ineffectiveness occurs, in certain circumstances, when the change in the total fair value of the derivative instrument differs from the change in the value of our expected future cash outlays for the purchase of aircraft fuel. Ineffectiveness is recognized immediately in interest income and other. If a hedge does not qualify for hedge accounting, the periodic changes in its fair value are also recognized in interest income and other. When aircraft fuel is consumed and the related derivative contract settles, any gain or loss previously recorded in other comprehensive income is recognized in aircraft fuel expense. All cash flows related to our fuel hedging derivatives are classified as operating cash flows. Our current approach to fuel hedging is to enter into hedges on a discretionary basis without a specific target of hedge percentage needs. 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, 2017 related to our outstanding fuel hedging contracts that were designated as cash flow hedges for accounting purposes. Jet fuel swap Jet fuel collar agreements Heating oil collar agreements Total Third Quarter 2017 10 % — % — % 10 % Fourth Quarter 2017 10 % — % — % 10 % 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): Fuel derivatives June 30, December 31, Asset fair value recorded in prepaid expense and other (1) $ 2 $ 22 Liability fair value recorded in other accrued liabilities (2) 2 — Longest remaining term (months) 6 12 Hedged volume (barrels, in thousands) 960 1,920 Estimated amount of existing (gains) expected to be reclassified into earnings in the next 12 months $ — $ (22 ) Three Months Ended June 30, Six Months Ended June 30, Fuel derivatives 2017 2016 2017 2016 Hedge effectiveness (gains) recognized in aircraft fuel expense $ (1 ) $ — $ (4 ) $ — Hedge (gains) on derivatives recognized in comprehensive income (7 ) (31 ) (17 ) (31 ) Percentage of actual consumption economically hedged 10 % — % 10 % — % (1) Gross asset of each contract prior to consideration of offsetting positions with each counterparty and prior to the impact of collateral paid. (2) Gross liability of each contract prior to consideration of offsetting positions with each counterparty and prior to the impact of collateral paid. Any outstanding derivative instrument exposes us to credit loss in connection with our fuel contracts in the event of nonperformance by the counterparties to our agreements, but we do not expect that any of our counterparties will fail to meet their obligations. 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. The impact of offsetting derivative instruments is depicted below (in millions): Gross Amount of Recognized Gross Amount of Cash Collateral Net Amount Presented on Balance Sheet Fuel derivatives Assets Liabilities Offset Assets Liabilities As of June 30, 2017 $ 2 $ 2 $ — $ 2 $ 2 As of December 31, 2016 22 — — $ 22 —

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value Under the Fair Value Measurements and Disclosures topic of 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 quoted prices in active markets for identical assets or liabilities; Level 2 quoted prices in active markets for similar assets and liabilities and inputs that are observable 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 and liabilities 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, 2017 and December 31, 2016 (in millions): June 30, 2017 Assets Level 1 Level 2 Level 3 Total Cash equivalents $ 393 $ — $ — $ 393 Available-for-sale investment securities 12 195 — 207 Aircraft fuel derivatives — 2 — 2 $ 405 $ 197 $ — $ 602 Liabilities Aircraft fuel derivatives $ — $ 2 $ — $ 2 $ — $ 2 $ — $ 2 December 31, 2016 Assets Level 1 Level 2 Level 3 Total Cash equivalents $ 313 $ — $ — $ 313 Available-for-sale investment securities 115 220 — 335 Aircraft fuel derivatives — 22 — 22 $ 428 $ 242 $ — $ 670 Refer to Note 2 for fair value information related to our outstanding debt obligations as of June 30, 2017 and December 31, 2016 . Cash equivalents Our cash equivalents include money market securities and commercial paper 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. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within our fair value hierarchy. Available-for-sale investment securities Included in our available-for-sale investment securities are U.S. treasury bills, time deposits and commercial paper with maturities of greater than 90 days but less than one year. The U.S. treasury bills 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 our time deposits and commercial paper instruments are based on observable inputs in non-active markets and are therefore classified as Level 2 in the hierarchy. We did not record any significant gains or losses on these securities during the three and six months ended June 30, 2017 and 2016 . Aircraft fuel derivatives Our aircraft fuel derivatives include swaps, collars, and basis swaps which are not traded on public exchanges. Heating oil and jet fuel are the products underlying these hedge contracts as they are highly correlated with the price of jet fuel. 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 in the hierarchy. 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.

New Accounting Pronouncements [Policy Text Block]	Recent Accounting Pronouncements During the first quarter of 2017, we adopted Accounting Standards Update, or ASU, 2015-17, Income Taxes, Balance Sheet Classification of Deferred Taxes topic of the FASB Codification, or Codification. This standard requires all deferred tax assets and liabilities to be classified as non-current on the balance sheet instead of separating deferred taxes into current and non-current amounts. In addition, valuation allowance allocations between current and non-current deferred tax assets are no longer required because those allowances also will be classified as non-current. Our condensed consolidated balance sheet as of December 31, 2016 reflects retrospective application. As a result of the adoption, $9 million of deferred tax liabilities previously included within other accrued liabilities and $164 million of deferred tax assets previously included within current assets have been moved to long-term liabilities on our December 31, 2016 balance sheet. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . Under ASU 2016-02, a lessee will recognize liabilities for lease payments and right-of-use assets representing its right to use the underlying asset for the lease term. While we are still evaluating the full impact of adopting the amendments on our consolidated financial statements and disclosures, we have determined that it will impact our accounting for aircraft and other leases. The amendments are effective for fiscal years beginning after December 15, 2018 and include interim periods within those fiscal years. Early adoption is permitted, and companies are required to use a modified retrospective approach at the earliest period presented. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash . The amendments clarified how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. The amendments are effective for fiscal years beginning after December 15, 2017 and include interim periods within those years. Early adoption is permitted. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which supersedes existing revenue recognition guidance. Under the new standard, a company will recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to in exchange for those goods or services. The standard allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year to interim and annual reporting periods beginning after December 15, 2017 and permitted early adoption of the standard, but not prior to December 15, 2016. While we are evaluating the full impact of ASU 2014-09 on our consolidated financial statements, we have determined that it will impact our loyalty program accounting. JetBlue will no longer be allowed to use the incremental cost method when recording the financial impact of TrueBlue® points earned on qualifying JetBlue purchases. We will be required to re-value our liability with a relative fair value approach, which is anticipated to significantly increase the related liability. In addition, the standard will likely result in a change in the timing and classification of our revenue recognition for certain ancillary fees directly related to passenger revenue tickets, as these services are no longer likely to be considered distinct performance obligations. Fees associated with these services are likely to be recognized as of the date of travel, not when assessed to the customer, and classified as passenger revenue. JetBlue currently anticipates adopting ASU 2014-09 effective January 1, 2018 using the full retrospective method, however, this decision is not final and is subject to the completion of our analysis of the standard. We will continue our evaluation of ASU 2014-09 through the date of adoption.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	Available-for-sale investment securities Included in our available-for-sale investment securities are U.S. treasury bills, time deposits and commercial paper with maturities of greater than 90 days but less than one year. The U.S. treasury bills 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 our time deposits and commercial paper instruments are based on observable inputs in non-active markets and are therefore classified as Level 2 in the hierarchy. We did not record any significant gains or losses on these securities during the three and six months ended June 30, 2017 and 2016 .
