Income Taxes [Line Items]
Income Taxes	Income Taxes At December 31, 2020, we had approximately $16.5 billion of federal net operating losses (NOLs) available to reduce future federal taxable income, of which $8.5 billion will expire beginning in 2023 if unused and $8.0 billion can be carried forward indefinitely (NOL Carryforwards). We also had approximately $5.0 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2020, which will expire in taxable years 2020 through 2040 if unused. Our ability to use our NOL Carryforwards depends on the amount of taxable income generated in future periods. We provide a valuation allowance for our deferred tax assets, which include our NOLs, when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We presently have a $34 million valuation allowance on certain net deferred tax assets related to state NOL Carryforwards. There can be no assurance that an additional valuation allowance on our net deferred tax assets will not be required. Such valuation allowance could be material. During the three months ended March 31, 2021 and 2020, we recorded an income tax benefit of $323 million and $649 million, respectively.
