Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our wholly-owned subsidiaries. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes. We reclassified certain prior period amounts, none of which were material, to conform to the current period presentation.
	Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items and restructuring and other items, considered necessary for a fair statement of results for the interim periods presented.
	Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, changes in global economic conditions and other factors, operating results for the three months ended March 31, 2014 are not necessarily indicative of operating results for the entire year.

Business Combinations [Abstract]	'
Business Combination Disclosure [Text Block]	'
	OIL REFINERY
	Fuel expense is our single largest expense. Prior to our acquisition of an oil refinery, global demand for jet fuel and related products had increased while jet fuel refining capacity had decreased in the U.S. (particularly in the Northeast), resulting in increases in the refining margin reflected in the prices we paid for jet fuel. In June 2012, we purchased an oil refinery as part of our strategy to mitigate the increasing cost of the refining margin we pay.
	Refinery Operations and Strategic Agreements
	The refinery uses crude oil purchased from BP under a multi-year agreement. The refinery's production consists of jet fuel, as well as gasoline, diesel and other refined products ("non-jet fuel products"). Under a multi-year agreement, we are exchanging a significant portion of the non-jet fuel products with Phillips 66 for jet fuel to be used in our airline operations. In addition, we sell non-jet fuel products to BP under a buy/sell agreement, effectively exchanging those non-jet fuel products for jet fuel. The gross fair value of the products exchanged under these agreements during the three months ended March 31, 2014 and 2013 was $1.0 billion and $1.3 billion, respectively.
	Segment Reporting
	Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP. Our segments are not designed to measure operating income or loss directly related to the products and services included in each segment on a stand-alone basis.

	(1)	Represents transfers, valued on a market price basis, from the refinery to the airline segment for use in airline operations. We determine market price by reference to the market index for the primary delivery location for jet fuel from the refinery, which is New York Harbor.
	(2)	Represents value of products delivered under our strategic agreements, as discussed above, determined on a market price basis.
	(3)	Represents sales of refined products to third parties. These sales were at or near cost; accordingly, the margin on these sales is de minimis.

	Cash Equivalents, Short-term Investments and Restricted Cash Equivalents and Investments. Cash equivalents and short-term investments generally consist of money market funds and treasury bills. Restricted cash equivalents and investments primarily support letters of credit that meet certain projected self-insurance obligations and airport commitments and generally consist of money market funds and time deposits. These investments are recorded at cost, which approximates fair value. Fair value is based on a market approach using prices and other relevant information generated by market transactions involving identical or comparable assets.
	Long-term Investments. Our long-term investments that are measured at fair value primarily consist of equity investments in Grupo Aeroméxico, S.A.B. de C.V., the parent company of Aeroméxico, and GOL Linhas Aéreas Inteligentes, S.A, the parent company of GOL. Shares of the parent companies of Aeroméxico and GOL are traded on public exchanges and we have valued our investments based on quoted market prices. The investments are classified in other noncurrent assets.
	Hedge Derivatives. Our derivative contracts are generally negotiated with counterparties without going through a public exchange. Accordingly, our fair value assessments give consideration to the risk of counterparty default (as well as our own credit risk).
	•	Fuel Contracts. Our fuel hedge portfolio consists of call options, put options, swaps, and futures. The products underlying the hedge contracts include crude oil, diesel fuel and jet fuel as these commodities are highly correlated with the price of jet fuel that we consume. Option contracts are valued under an income approach using option pricing models based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Volatilities used in these valuations ranged from 9% to 22% depending on the maturity dates, underlying commodities and strike prices of the option contracts. Swap contracts are valued under an income approach using a discounted cash flow model based on data either readily observable or derived from public markets. Discount rates used in these valuations vary with the maturity dates of the respective contracts and are based on LIBOR. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices.
	•	Interest Rate Contracts. Our interest rate derivatives consist of swap contracts and are valued primarily based on data readily observable in public markets.
	•	Foreign Currency Exchange Contracts. Our foreign currency derivatives consist of Japanese yen and Canadian dollar forward contracts and are valued based on data readily observable in public markets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives [Text Block]	'
	DERIVATIVES
	Changes in aircraft fuel prices, interest rates and foreign currency exchange rates impact our results of operations. In an effort to manage our exposure to these risks, we enter into derivative contracts and adjust our derivative portfolio as market conditions change.
	Aircraft Fuel Price Risk
	Changes in aircraft fuel prices materially impact our results of operations. We actively manage our fuel price risk through a hedging program intended to reduce the financial impact on us from changes in the price of jet fuel. We utilize several different contract and commodity types in this program and frequently test its economic effectiveness against our financial targets. We rebalance the hedge portfolio from time to time according to market conditions, which may result in locking in gains or losses on hedge contracts prior to their settlement dates.
	We generally do not designate our fuel derivative contracts as accounting hedges. We record changes in the fair value of our fuel hedges in aircraft fuel and related taxes. These changes in fair value include settled gains and losses as well as mark to market adjustments ("MTM adjustments"). MTM adjustments are based on market prices as of the end of the reporting period for contracts settling in future periods. During the three months ended March 31, 2014 and 2013, we recorded $78 million and $77 million in fuel hedge gains, respectively.

	As of March 31, 2014, we have recorded $136 million of net gains on cash flow hedge contracts in accumulated other comprehensive loss, which are scheduled to settle and be reclassified into earnings within the next 12 months.
	Credit Risk
	To manage credit risk associated with our aircraft fuel price, interest rate and foreign currency hedging programs, we evaluate counterparties based on several criteria including their credit ratings and limit our exposure to any one counterparty.
	Our hedge contracts contain margin funding requirements. The margin funding requirements may cause us to post margin to counterparties or may cause counterparties to post margin to us as market prices in the underlying hedged items change. Due to the fair value position of our hedge contracts, we received net margin of $37 million and $65 million as of March 31, 2014 and December 31, 2013, respectively. Margin received is recorded in accounts payable and margin posted is recorded in prepaid expenses and other.

	Venezuelan Currency Devaluation
	In 2013, the Venezuelan government devalued its currency to an official rate of 6.3 bolivars per U.S. dollar and announced the creation of the SICAD foreign currency exchange mechanism, a complementary currency auction system. In January 2014, the Venezuelan government announced that while the official exchange rate remained at 6.3 bolivars, some sectors of the economy, including airlines, will use the SICAD reference rate for future repatriation requests. At the time of the announcement, the SICAD reference rate was 11.4 per U.S. dollar. We have recorded a $23 million charge in miscellaneous, net within other (expense) income to reflect the devaluation of currency and travel agency receivables related to 2014 sales that were denominated in bolivars.
	As of March 31, 2014, we had $122 million related to our 2013 airline operations for which repatriation had been requested, but not yet authorized by the Venezuelan government. In January 2014, the Venezuelan government announced its intention to honor the published exchange rate (6.3 bolivars per U.S. dollar) for all 2013 repatriations related to international passenger air travel and cargo. Accordingly, at March 31, 2014, these amounts are valued at the official rate of 6.3 bolivars per U.S. dollar. In addition to the 2013 balance, we have $59 million (valued at SICAD rate) related to our March 2014 quarter operations for which repatriation has been requested, but not yet authorized. We will continue to monitor how the economic situation evolves in Venezuela as we remain at risk to the potential for further currency devaluations.
	Legal Contingencies
	We are involved in various legal proceedings related to employment practices, environmental issues, antitrust matters and other matters concerning our business. We record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount of loss can be reasonably estimated. We cannot reasonably estimate the potential loss for certain legal proceedings because, for example, the litigation is in its early stages or the plaintiff does not specify the damages being sought. Although the outcome of the legal proceedings in which we are involved cannot be predicted with certainty, management believes that the resolution of these matters will not have a material adverse effect on our Condensed Consolidated Financial Statements.
	Other Contingencies
	General Indemnifications
	We are the lessee under many commercial real estate leases. It is common in these transactions for us, as the lessee, to agree to indemnify the lessor and the lessor's related parties for tort, environmental and other liabilities that arise out of or relate to our use or occupancy of the leased premises. This type of indemnity would typically make us responsible to indemnified parties for liabilities arising out of the conduct of, among others, contractors, licensees and invitees at, or in connection with, the use or occupancy of the leased premises. This indemnity often extends to related liabilities arising from the negligence of the indemnified parties, but usually excludes any liabilities caused by either their sole or gross negligence or their willful misconduct.
	Our aircraft and other equipment lease and financing agreements typically contain provisions requiring us, as the lessee or obligor, to indemnify the other parties to those agreements, including certain of those parties' related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or such other equipment.
	We believe that our insurance would cover most of our exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft and other equipment lease and financing agreements described above. While our insurance does not typically cover environmental liabilities, we have certain insurance policies in place as required by applicable environmental laws.
	Certain of our aircraft and other financing transactions include provisions that require us to make payments to preserve an expected economic return to the lenders if that economic return is diminished due to certain changes in law or regulations. In certain of these financing transactions, we also bear the risk of certain changes in tax laws that would subject payments to non-U.S. lenders to withholding taxes.
	We cannot reasonably estimate our potential future payments under the indemnities and related provisions described above because we cannot predict (1) when and under what circumstances these provisions may be triggered and (2) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.
	Employees Under Collective Bargaining Agreements
	At March 31, 2014, we had approximately 78,870 full-time equivalent employees. Approximately 18% of these employees were represented by unions.
	War-Risk Insurance Contingency
	As a result of the terrorist attacks on September 11, 2001, aviation insurers significantly (1) reduced the maximum amount of insurance coverage available to commercial air carriers for liability to persons (other than employees or passengers) for claims from acts of terrorism, war or similar events and (2) increased the premiums for such coverage. Since September 24, 2001, the U.S. government has been providing U.S. airlines with war-risk insurance to cover losses, including those resulting from terrorism, to passengers, third parties (ground damage) and the aircraft hull. The U.S. Secretary of Transportation has extended coverage through September 30, 2014. The withdrawal of government support of airline war-risk insurance would require us to obtain war-risk insurance coverage commercially. Such commercial insurance could have substantially less desirable coverage than currently provided by the U.S. government, may not be adequate to protect our risk of loss from future acts of terrorism or may result in a material increase to our operating expense.
	Other
	We have certain contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.

	RESTRUCTURING AND OTHER ITEMS
	We recorded restructuring charges of $49 million and $102 million in the March 2014 and 2013 quarters, respectively, primarily related to our fleet restructuring initiative and certain other items. Under the fleet restructuring initiative, we are focused on removing older, less efficient aircraft from our fleet and replacing them with B-737-900 ER, B-717-200 and CRJ-900 aircraft. These restructuring charges include remaining lease payments for grounded aircraft, the acceleration of depreciation and lease return costs.
	As we restructure our fleet and assess our fleet plans, we will continue to evaluate older, retiring aircraft and related equipment for changes in depreciable life, impairment and lease termination costs. The retirement of aircraft, when permanently removed from our fleet, will likely result in lease termination and other charges. The timing and amount of these charges will depend on a number of factors, including final negotiations with lessors, the timing of removing aircraft from service and ultimate disposition of aircraft included in the fleet restructuring program. We expect to benefit from reduced future maintenance cost and improved operational and fuel efficiency that we will experience over the life of the new aircraft.
	The following table shows the balances and activity for restructuring charges:
	(in millions)	Lease Restructuring
	Liability as of December 31, 2013	$	168

	DIVIDEND AND SHARE REPURCHASE
	In May 2013, we announced a plan to return more than $1 billion to shareholders over the next three years. As part of this plan, our Board of Directors initiated a quarterly dividend program. On February 7, 2014, the Board of Directors declared the third payment in this program, a $0.06 per share dividend for shareholders of record as of February 21, 2014. This dividend was paid in March 2014 and totaled $51 million.
	Also as a part of the plan, the Board of Directors authorized a $500 million share repurchase program to be completed no later than June 30, 2016. During the three months ended March 31, 2014, we repurchased and retired four million shares at a cost of $125 million, bringing our total repurchases under the program to $375 million. We expect to complete our $500 million share repurchase authorization in the June quarter.
