Disclosure Text Block [Abstract]
Basis of Presentation	1 . Basis of Presentation The Company American Express Company (the Company) is a global services company that provides customers with access to products, insights and experiences that enrich lives and build business success. The Company’s principal products and services are charge and credit payment card products and travel-related services offered to consumers and businesses around the world. Business travel-related services are offered through the non-consolidated joint venture, American Express Global Business Travel (GBT JV). The Company’s various products and services are sold globally to diverse customer groups, including consumers, small businesses, mid-sized companies and large corporations. These products and services are sold throu gh various channels, including direct mail, online applications, in-house and third-party sales forces and direct response advertising . Effective for the first quarter of 2016, the Company realigned its segment presentation to reflect the organizational c hanges announced during the fourth quarter of 2015. Prior periods have been restated to conform to the new reportable operating segments, which are as follows: U.S. Consumer Services (USCS), including the proprietary U.S. Consumer Card Services business an d travel services in the United States ; International Consumer and Network Services (ICNS), including the proprietary International Consumer Card Services business, Global Network Services (GNS) business and travel services outside the United States ; Globa l Commercial Services (GCS), including the proprietary Global Corporate Payments (GCP) business, small business services businesses in the United States and internationally ( collectively, Global Small Business Services ), merchant financing products and for eign exchange services operations ; and Global Merchant Services (GMS), including the Global Merchant Services business and global loyalty coalition businesses. Corporate functions and certain other businesses and operations are included in Corporate & Other. The accompanying Consolidated Financial Statements should be read in conjunction with the Consolidated Financial S tatements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (the Annual Report). If not mate rially different, certain footnote disclosures included therein have been omitted from this Quarterly Report on Form 10-Q. The interim consolidated financial information in this report has not been audited. In the opinion of management, all adjustments, w hich consist of normal recurring adjustments necessary for a fair statement of the interim period consolidated financial information, have been made. Results of operations reported for interim periods are not necessarily indicative of results for the entir e year. The preparation of Consolidated Financial S tatements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of asset s, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. These accounting estimates reflect the best judgment of management, but actual results could differ. Certain reclassifications of prior period amounts have bee n made to conform to the current period presentation. During 2016, the Company determined that in the Consolidated Statements of Cash Flows for the comparative periods ended June 30, 2015, September 30, 2015 and December 31, 2015, certain activities relate d to long-term debt repayments were misclassified between financing activities and operating activities. There is no impact to the Consolidated Statements of Income or Consolidated Balance Sheets. The Company has evaluated the effects of these misclassific ations and concluded that none are material to any of its previously issued quarterly or annual Consolidated Financial Statements. Nevertheless, the Company has elected to revise prospectively the comparative periods mentioned above. For the six months en ded June 30, 2015, this revision resulted in a $66 million decrease to both Net cash used in financing activities and Net cash provided by operating activities. In addition, travel commissions and fees, which were separately disclosed on the Consolidated S tatements of Income historically, are now included within Other fees and commissions. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued new accounting guidance on revenue recognition. The guidance establishes the principles to apply to determine the amount and timing of revenue recognition, specifying the accounting for certain costs related to revenue, and requiring additional disclosures about the nature, amount, timing and uncertainty of revenues and related cash flows. The guidance, as amended, supersedes most of the current revenue recognition requirements, and is effective January 1, 2018, with early adoption as of January 1, 2017, permitted. The Company does not intend to adopt the new standar d early and continues to evaluate the impact this guidance, including the method of implementation, will have on its financial position, results of operations and cash flows, among other items. In January 2016, the FASB issued new accounting guidance on th e recognition and measurement of financial assets and fin ancial liabilities. The guidance , which is effective January 1, 2018, makes targeted changes to current GAAP, specifically to the classification and measurement of equity securities, and to certain d isclosure requirements associated with the fair value of financial instr uments. The Company continues to e valuate the impact this guidance will have on its financial position, results of operations and cash flows, among other items. In February 2016, the F ASB issued new accounting guidance on leases. The guidance, which is effective January 1, 2019, with early adoption permitted, requires virtually all leases to be recognized on the Consolidated Balance Sheets . The Company continues to evaluate the impact t his guidance will have on its financial position, results of operations and cash flows, among other items. In March 2016, the FASB issued new accounting guidance on employee share-based payments. The guidance, which is effective January 1, 2017, with early adoption permitted, simplifies various aspects of the accounting for share-based payment transactions, including the income tax consequences, accounting for award forfeitures, and classification on the Consolidated S tatement s of C ash Flows. The Company co ntinues to evaluate the impact this guidance will have on its financial position, results of operations and cash flows, among other items. In June 2016, the FASB issued new accounting guidance for recognition of credit losses on financial instruments, whi ch is effective January 1, 2020, with early adoption permitted on January 1, 2019. The guidance introduces a new credit reserving model known as the Current Expected Credit Loss (CECL) model , which is based on expected losses, and differs significantly fr om the incurred loss approach used today. The CECL model requires measurement of expected credit losses not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward- looking information and will likely result in earlier recognition of credit reserves . The Company is currently evaluating the impact the new guidance will have on its financial position, result s of operations and cash flows; h owever, it is expec ted that the new CECL model will alter the assumptions used in calculating credit losses on Card Member loans and receivables, among other financial instruments, and may result in material changes to the Company’s credit reserve s.

In addition, if the Company initiates collection procedures on an account prior to the account becoming 9 0 days past billing, the associated Card Member receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. Delinquency data for periods other than 90 days past billing is not ava ilable due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances.

In addition, because the Company considers uncollectible interest and/or fees in estimating its reserves for credit losses, a net write-off rate including principal, interest and/or fees is also presented. Impaired Card Member Loans and R eceivables Impaired loans and receivables are individual larger balance or homogeneous pools of smaller balance loans and receivables for which it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the Card Member agreement.

Asset Securitizations [Abstract]
Asset Securitizations	6 . Asset Securitizations The Company periodically securitizes Card Member loans and receivables arising from its card business , including Card Member loans and receivables HFS, through the transfer of those assets to securitization trusts. The t rusts then issue debt securities to third-party investors, collaterali zed by the transferred assets. The following table provides information on the restricted cash held by the American Express Issuance Trust II (the Charge Trust) and the American Expres s Credit Account Master Trust (the Lending Trust, collectively the Trusts) as of June 30 , 2016 and December 31, 2015 , included in Other assets on the Consolidated Balance Sheets: (Millions) 2016 2015 Charge Trust $ 2 $ 2 Lending Trust 33 153 Total $ 35 $ 155 These amounts relate to collections of Card Member loans and receivables to be used by the Trusts to fund future expenses and obligations, including interest on debt securities, credit losses and upcoming debt maturities. American Express Travel Related Services Company, Inc. ( TRS ) , in its role as servicer of the Trusts, has the power to direct the most significant activity of the Trusts, which is the collection of the underlying Card Member loans and receivables. In addition, TRS directly and indirectly (through its consolidated subsidiaries) holds all of the variable interests in both Trusts, with the exception of the de bt securities issued to third-party investors. As of June 30 , 2016 , TRS’ direct and indirect ownership of variable interests was $ 13.9 billion for the Lending Trust and $ 2.5 billion for the Charge Trust. These variable interests held by TRS provide it with the right to receive benefits and the obligation to absorb losses, which could be significant to both the Lending Tr ust and the Charge Trust. Based on these considerations, TRS is the primary beneficiary of both Trusts and therefore consolidates both Trusts. Under the respective t erms of the Charge Trust and the Lending Trust agreements, the occurrence of certain trigg ering events associated with the performance of the assets of each Trust could result in payment of trust expenses, establishment of reserve funds, or , in a worst-case scenario, early amortiza tion of debt securities. During the six months ended June 30 , 2016 and the year ended December 31, 2015 , no such triggering events occurred.

Contingencies Disclosure [Abstract]
Contingencies	8 . Contingencies In the ordinary course of business, the Company and its subsidiaries are subject to various claims, investigations, examinations, pending and potential legal actions, and other matters relating to compliance with laws and regulations (collectively, legal proceedings). The Company discloses its material legal proceedings under Part II, Item 1. “Legal Proceedings” in this Quarterly Report on Form 10-Q and Part I, Item 3. “Legal Proceedings” in the Annual Report . The Company has recorded reserves for certain of its outstanding legal proceedings. A reserve is recorded when it is both (a) probable that a loss has occurred and (b) the amount of loss can be reasonably estimated. There may be instances in which an exposure to loss exceeds the recorded reserve. The Company evaluates, on a quarterly basis, developments in legal proceedings that could cause an increase or decrease in the amount of the reserve that has been previously recorded, or a revision to the disclosed estimated r ange of possible losses, as applicable . The Company’s legal proceedings range from cases brought by a single plaintiff to class actions with millions of putative class members. These legal proceedings involve various lines of business of the Company and a variety of claims (including, but not limited to, common law tort, contract, antitrust and consumer protection claims), some of which present novel factual allegations and/or unique legal theories. While some matters pending against the Company specify t he damages claimed by the plaintiff or class, many seek an unspecified amount of damages or are at very early stages of the legal process. Even when the amount of damages claimed against the Company are stated, the claimed amount may be exaggerated and/or unsupported. As a result, some matters have not yet progressed sufficiently through discovery and/or development of important factual information and legal issues to enable the Company to estimate an amount of loss or a range of possible loss, while other matters have progressed sufficiently such that the Company is able to estimate an amount of loss or a range of possible loss . For those disclosed material legal proceedings where a loss is reasonably possible in future periods, whether in excess of a rela ted reserve for legal contingencies or where there is no such reserve, and for which the Company is able to estimate a range of possible loss, the current estimated range is zero to $ 350 million in exce ss of any reserves related to th o se matters. This range represents management’s estimate based on currently available information and does not represent the Company’s maximum loss exposure; actual results may vary significantly. As such proceedings evolve, including the merchant claims described unde r “Legal Proceedings ” in the Annual Report, the Company may need to increase its range of possible loss or reserves for legal contingencies . Based on its current knowledge, and taking into consideration its litigation-related liabilities, the Company beli eves it is not a party to, nor are any of its properties the subject of, any legal proceeding that would have a material adverse effect on the Company’s consolidated financial condition or liquidity. However, in light of the uncertainties involved in such matters, it is possible that the outcome of legal proceedings, including the possible resolution of merchant claims, could have a material impact on the Company’s results of operations .

These instruments derive their value from an underlying variable or multiple variables, including interest rate s , foreign exchange rates , and equity index or price , and are carried at fair value on the Consolidated Balance Sheets . These instruments enable end users to increase, reduce or alter exposure to various market risks and, for that reason, are an integral component of the Com pany’s market risk management. The Company does not transact in derivatives for trading purposes. In relation to the Company’s credit risk, under the terms of the derivative agreements it has with its various counterpartie s, the Company is not required to either immediately settle any outstanding liability balances or post collateral upon the occurrence of a specified credit risk-related event . Based on the assessment of credit risk of the Company’s derivative counterpartie s as of June 30 , 2016 and December 31, 2015 , the Company does not have derivative positions that warrant credit valuation adjustments. The following t able summarizes the total fair value, excluding interest acc ruals, of derivative assets and l iabilities as of June 30 , 2016 and December 31, 2015 : Other Assets Other Liabilities Fair Value Fair Value (Millions) 2016 2015 2016 2015 Derivatives designated as hedging instruments: Interest rate contracts Fair value hedges $ 452 $ 236 $ ― $ 9 Foreign exchange contracts Net investment hedges 216 191 141 57 Total derivatives designated as hedging instruments 668 427 141 66 Derivatives not designated as hedging instruments: Foreign exchange contracts, including certain embedded derivatives (a) 475 117 248 135 Total derivatives, gross 1,143 544 389 201 Less: Cash collateral netting (b) (361) (155) ― ― Derivative asset and derivative liability netting (c) (169) (107) (169) (107) Total derivatives, net (d) $ 613 $ 282 $ 220 $ 94 Includes foreign currency derivatives embedded in certain operating agreements. Represents the offsetting of derivative instruments and the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from derivative instrument(s) executed with the same counterparty under an enforceable master netting arrangement. The Company received non-cash collateral from a counterparty in the form of security interests in U.S. Treasury securities with a fair value of $30 million as of June 30, 2016 , none of which was sold or repledged . Such non-cash collateral economically reduced the Company’s risk exposure to $583 million but did not reduce the net exposure on the Company’ s Consolidated Balance Sheets. The C ompany did not have any such non-cash collateral as of December 31, 2015 . Additionally, the Company posted $ 159 million and $ 149 million as of June 30 , 2016 and December 31, 2015 , respectively , as initial margin on its centrally c leared interest rate swaps; such amounts are recorded within Other receivables on the Consolidated Balance Sheets and are not netted against the derivative balances. Represents the amount of netting of derivative assets and derivative liabilities executed with the same counterparty under an enforceable master netting arrangement. The Company has no individually significant derivative counterparties and therefore, no significant risk exposure to any single derivative counterparty. The total net derivative a ssets and derivative liabilities are presented within O ther assets and O ther liabilities on the Consolidated Balance Sheets. A majority of the Company’s derivative assets and liabilities as of June 30 , 2016 and December 31, 2015 are subject to mast er netting agreements with its deriva tive counterparties. T he Company has no derivative amounts subject to enforceable master netting arrangements that are not offset on the Consolidated Balance Sheets. Fair Value Hedges The Company is exposed to interest rate risk associated with its fixed-rate long-term debt. The Company uses interest rate swaps to economically convert certain fixed-rate debt obligations to floating-rate obligations at the time of issuance. T he Company hedged $ 20.3 billion and $ 18.8 billion of its fixed-rate debt to floating-rate debt using interest rate swaps as of June 30 , 2016 and December 31, 2015 , respectively . The following table summarizes the impact on the Consolidated Statements of Income associated with the Company’s fair value hedges for the three and six months ended June 30 : Three Months Ended June 30 (Millions) Gains (losses) recognized in income Derivative contract Hedged item Net hedge Amount Amount ineffectiveness Derivative relationship Income Statement Line Item 2016 2015 Income Statement Line Item 2016 2015 2016 2015 Interest rate contracts Other expenses $ 61 $ (89) Other expenses $ (53) $ 85 $ 8 $ (4) Six Months Ended June 30 (Millions) Gains (losses) recognized in income Derivative contract Hedged item Net hedge Amount Amount ineffectiveness Derivative relationship Income Statement Line Item 2016 2015 Income Statement Line Item 2016 2015 2016 2015 Interest rate contracts Other expenses $ 226 $ (26) Other expenses $ (224) $ 29 $ 2 $ 3 The Company also recognized a net reduction in inter est expense on long-term debt of $ 59 million and $ 71 million for the three months ended June 30 , 2016 and 2015 , respectively, and $ 118 million and $ 140 million for the six months ended June 30 , 2016 and 2015 , respectively, primarily related to the net settlements (interest accruals) on the Company’s interest rate derivatives designated as fair value hedges. Net Investment Hedges The effective portion of the gain or (loss) on net investment hedges, net of taxes, recorded in AOCI as part of the cu mulative translation adjustment, was $ 135 million and $ (34) million for the three months ended June 30 , 2016 and 2015 , respectively, and $ 43 million and $ 161 million for the six months ended June 30 , 2016 and 2015 , respectively, with a ny ineffective portion recognized in Other expenses during the period of change . The following table summarizes the impact on the Consolidated Statements of Income associated with the Company’s net investment hedges for the three and six months ended June 30: Three Months Ended June 30: (Millions) Gains (losses) recognized in income Amount reclassified from AOCI into income Net hedge ineffectiveness Description Income Statement Line Item 2016 2015 Income Statement Line Item 2016 2015 Net investment hedges: Foreign exchange contracts Other, net expenses $ 5 $ ― Other, net expenses $ ― $ 1 Six Months Ended June 30: (Millions) Gains (losses) recognized in income Amount reclassified from AOCI into income Net hedge ineffectiveness Description Income Statement Line Item 2016 2015 Income Statement Line Item 2016 2015 Net investment hedges: Foreign exchange contracts Other, net expenses $ 5 $ ― Other, net expenses $ ― $ 1 Derivatives Not Designated as Hedges The changes in the fair value of derivatives that are not designated as hedges are intended to offset the related foreign exchange gains or losses of the underlying foreign currency exposures. The changes in the fair value of the derivatives and the related underlying foreign currency exposures result ed in net gains of $ 6 million and $ 8 million for the three months ended June 30 , 2016 and 2015 , respectively, and a net loss of $ 8 million and a net gain of $ 105 mi llion for the six months ended June 30 , 2016 and 2015 , respectively, and are recognized in Other expenses. Related to its derivatives not designated as hedges, the Company previously disclosed in Note 9 to the Consolid ated Financial Statements in its Quar terly Report on Form 10-Q for the period ended June 30, 2015, a gain of $40 million for the three months ended June 30, 2015, and a loss of $4 million for the six months ended June 30, 2015. These amounts should have been disclosed as gains of $87 million and $381 million, respectively, which are the amou nts used to calculate the above- referenced net gains of $8 million and $105 million. These changes to the previously disclosed amounts have no impact on the Consolidated Statements of Income, Balance Sheets or Cash Flows. The changes in the fair value of an embedded derivative are nil and a gain of $ 4 million for the three months ended June 30 , 2016 and 2015 , respectively, and gains of $ 6 million and $ 3 million for the six months ended June 30 , 2016 and 2015 , respectively, and are recognized in Card Member services and other expense.

Income Taxes	14 . Income Taxes The effective tax rate was 33.2 percent and 33.9 percent for the three months ended June 30 , 2016 and 2015 , respectively, and 33.8 percent and 34.0 percent for the six months ended June 30 , 2016 and 2015 , respectively. The tax rates in all periods primarily reflected the level of pretax income in relation to recurring permanent tax benefits and the geographic mix of business. The Company is under continuous examination by the In ternal Revenue Service (IRS) and tax authorities in other countries and states in which the Company has significant business operations. The tax years under examination and open for examination vary by jurisdiction. The IRS has completed its field examinat ion of the Company’s federal tax returns for years through 2007 ; however, refund claims for certain years continue to be reviewed by the IRS. In addition, the Company is currently under examination by the IRS for the years 2008 through 2014 . The C ompany believes it is reasonably possible that its unrecognized tax benefits could decrease within the next 12 months by as much as $ 237 million principally as a result of potential resolutions of prior years’ tax items with various taxing authorities . The prior years’ tax items include unrecognized tax benefits relating to the deductibility of certain expenses or losses and the attribution of taxable income to a particular jurisdiction or jurisdictions. Of the $ 237 million of unrecognized tax ben efits, approximately $ 21 million relates to amounts that if recognized would be recorded in shareholders’ equity and would not impact the Company’s results of operations or its effective tax rate.

Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributa ble to participating securities. The related participating securities are similarly excluded from the denominator . The dilutive effect of unex ercised stock options excludes from the computation of EPS 2.5 million and 0.6 million of options for the three months ended June 30 , 2016 and 2015 , respectively, and 1.7 million and 0.5 million of options for the six months ended June 30 , 2016 and 2015 , respectively, because inclusion of the options would have been anti-dilutive. For the three and six months ended June 30 , 2016 and 2015 , the Company met specified performance measures related to the $ 750 million of Subordinated Debentures issued in 2006, and maturing in 2036.

A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member’s billing statement date. In addition, if the Company initiates collection procedures on an account prior to the account becoming 9 0 days past billing, the associated Card Member receivable balance is classified as 90 days past billing. These amounts are shown above as 90+ Days Past Due for presentation purposes. Delinquency data for periods other than 90 days past billing is not ava ilable due to system constraints. Therefore, such data has not been utilized for risk management purposes. The balances that are current to 89 days past due can be derived as the difference between the Total and the 90+ Days Past Due balances.

Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributa ble to participating securities. The related participating securities are similarly excluded from the denominator . The dilutive effect of unex ercised stock options excludes from the computation of EPS 2.5 million and 0.6 million of options for the three months ended June 30 , 2016 and 2015 , respectively, and 1.7 million and 0.5 million of options for the six months ended June 30 , 2016 and 2015 , respectively, because inclusion of the options would have been anti-dilutive.
