Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Hyatt Hotels Corporation, a Delaware corporation, and its consolidated subsidiaries (collectively "Hyatt Hotels Corporation") provides hospitality and other services on a worldwide basis through the operation, management, franchising, ownership, development, and licensing of hospitality businesses. We operate, manage, franchise, own, lease, develop, license, or provide services to a portfolio of properties, consisting of full service hotels, select service hotels, resorts, and other properties, including timeshare, fractional, and other forms of residential, vacation, and condominium ownership units. At March 31, 2021, (i) we operated or franchised 479 full service hotels, comprising 164,260 rooms throughout the world, (ii) we operated or franchised 514 select service hotels, comprising 73,987 rooms, of which 434 hotels are located in the United States, and (iii) our portfolio included 8 franchised all-inclusive Hyatt-branded resorts, comprising 3,153 rooms. At March 31, 2021, our portfolio of properties operated in 68 countries around the world. Additionally, through strategic relationships, we provide certain reservation and/or loyalty program services to hotels that are unaffiliated with our hotel portfolio and operate under other tradenames or marks owned by such hotel or licensed by third parties. As used in these Notes and throughout this Quarterly Report on Form 10-Q, (i) the terms "Hyatt," "Company," "we," "us," or "our" mean Hyatt Hotels Corporation and its consolidated subsidiaries, (ii) the term "hotel portfolio" refers to our full service hotels, including our wellness resorts, and our select service hotels, (iii) the terms "properties," "portfolio of properties," or "property portfolio" refer to our hotel portfolio; all-inclusive resorts; and residential, vacation, and condominium ownership units that we operate, manage, franchise, own, lease, develop, license, or to which we provide services or license our trademarks, including under the Park Hyatt, Miraval, Grand Hyatt, Alila, Andaz, The Unbound Collection by Hyatt, Destination by Hyatt, Hyatt Regency, Hyatt, Hyatt Ziva, Hyatt Zilara, Thompson Hotels, Hyatt Centric, Caption by Hyatt, JdV by Hyatt, Hyatt House, Hyatt Place, tommie, UrCove, and Hyatt Residences Club brands, and (iv) the term "hospitality ventures" refers to entities in the hospitality industry in which we own less than a 100% equity interest. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information, the instructions to Form 10-Q, and Article 10 of Regulation S-X. Accordingly, they do not include all information or footnotes required by GAAP for complete annual financial statements. As a result, this Quarterly Report on Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the "2020 Form 10-K"). We have eliminated all intercompany accounts and transactions in our condensed consolidated financial statements. We consolidate entities under our control, including entities where we are deemed to be the primary beneficiary. Management believes the accompanying condensed consolidated financial statements reflect all adjustments, which are all of a normal recurring nature, considered necessary for a fair presentation of the interim periods. Impact of the COVID-19 Pandemic The COVID-19 pandemic and related travel restrictions and containment efforts have had a significant impact on the travel industry and, as a result, on our business. The impact began in the first quarter of 2020 and has continued into 2021. As a result, our financial results for the current interim period, and for the foreseeable future, are not comparable to past performance or indicative of long-term future performance. The extent, duration, and magnitude of the COVID-19 pandemic's effects will depend on various factors, all of which are highly uncertain and difficult to predict, including, but not limited to, the impact of the pandemic on global and regional economies, travel, and economic activity; actions taken by governments, businesses, and individuals in response to the pandemic, any additional resurgence, or COVID-19 variants; and the distribution and broad acceptance of COVID-19 vaccines. We are required to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying Notes. Our estimates and assumptions are subject to inherent

As our profitability hurdles are generally calculated on a full-year basis, we expect our contract assets to be insignificant at year end. Contract liabilities were comprised of the following: March 31, 2021 December 31, 2020 Deferred revenue related to the loyalty program $ 752 $ 733 Advanced deposits 55 44 Initial fees received from franchise owners 41 41 Deferred revenue related to insurance programs 33 47 Other deferred revenue 79 76 Total contract liabilities $ 960 $ 941 The following table summarizes the activity in our contract liabilities: 2021 2020 Beginning balance, January 1 $ 941 $ 920 Cash received and other 105 246 Revenue recognized (86) (262) Ending balance, March 31 $ 960 $ 904 Revenue recognized during the three months ended March 31, 2021 and March 31, 2020 included in the contract liabilities balance at the beginning of each year was $69 million and $137 million, respectively. This revenue primarily relates to the loyalty program, which is recognized net of redemption reimbursements paid to third parties. Revenue Allocated to Remaining Performance Obligations Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. Contracted revenue expected to be recognized in future periods was approximately $120 million at March 31, 2021, of which we expect to recognize approximately 10% of the revenue over the next 12 months and the remainder thereafter.

Other Investments HTM Debt Securities —We hold investments in held-to-maturity ("HTM") debt securities, which are investments in third-party entities that own or are developing certain of our hotels. The securities are mandatorily redeemable between 2021 and 2027. At March 31, 2021 and December 31, 2020, HTM debt securities recorded within other assets on our condensed consolidated balance sheets were as follows: March 31, 2021 December 31, 2020 HTM debt securities $ 103 $ 102 Less: allowance for credit losses (22) (21) Total HTM debt securities, net of allowances $ 81 $ 81 The following table summarizes the activity in our HTM debt security allowance for credit losses: 2021 2020 Allowance at January 1 $ 21 $ 12 Credit losses (a) 1 3 Allowance at March 31 $ 22 $ 15 (a) Credit losses were offset by interest income recognized in the same periods. The credit losses and interest income were both recognized in other income (loss), net on our condensed consolidated statements of income (loss). We estimated the fair value of HTM debt securities to be approximately $103 million and $100 million at March 31, 2021 and December 31, 2020, respectively. The fair values, which are classified as Level Three in the fair value hierarchy, are estimated using internally developed discounted cash flow models based on current market inputs for similar types of arrangements. The primary sensitivity in these models is based on the selection of appropriate discount rates. Fluctuations in these assumptions could result in different estimates of fair value. Equity Securities Without a Readily Determinable Fair Value —At both March 31, 2021 and December 31, 2020, we held $12 million

Business Combinations [Abstract]
Acquisitions and Dispositions	ACQUISITIONS AND DISPOSITIONS Acquisitions Grand Hyatt São Paulo —We previously held a 50% interest in the entities that own Grand Hyatt São Paulo, and we accounted for the investment as an unconsolidated hospitality venture under the equity method. During the three months ended March 31, 2021, we purchased the remaining 50% interest for $6 million of cash. Additionally, we repaid the $78 million third-party mortgage loan on the property, and we were released from our debt repayment guarantee (see Note 12). The transaction was accounted for as an asset acquisition, and we recognized a $69 million pre-tax gain related to the transaction in equity earnings (losses) from unconsolidated hospitality ventures on our condensed consolidated statements of income (loss). The pre-tax gain is primarily attributable a $42 million reversal of other long-term liabilities associated with our equity method investment and a $22 million reclassification from accumulated other comprehensive loss (see Note 13). Net assets acquired were determined as follows: Cash paid $ 6 Repayment of third-party mortgage loan 78 Fair value of our previously held equity method investment 6 Net assets acquired $ 90 Upon acquisition, we recorded $101 million of property and equipment and $11 million of deferred tax liabilities within our owned and leased hotels segment. Dispositions Hyatt Centric Center City Philadelphia —During the three months ended March 31, 2020, an unrelated third party invested in certain of our subsidiaries that developed Hyatt Centric Center City Philadelphia and adjacent parking and retail space in exchange for a 58% ownership interest, resulting in the derecognition of the nonfinancial assets of the subsidiaries. As a result of the transaction, we received $72 million of proceeds, recorded our 42% ownership interest as an equity method investment, and recognized a $4 million pre-tax gain in gains on sales of real estate on our condensed consolidated statements of income (loss) during the three months ended March 31, 2020. Our $22 million equity method investment was recorded at fair value based on the value contributed by our partner to the unconsolidated hospitality venture. As additional consideration, we received a $5 million investment in an equity security without a readily determinable fair value. Building —During the three months ended March 31, 2020, we sold a commercial building in Omaha, Nebraska for $6 million, net of closing costs and proration adjustments. In conjunction with the sale, we entered into a lease for a portion of the building and accounted for the transaction as a sale and leaseback and recorded a $4 million operating lease right-of-use asset and related lease liability on our condensed consolidated balance sheet. The sale resulted in a $4 million pre-tax gain, which was recognized in gains on sales of real estate on our condensed consolidated statements of income (loss) during the three months ended March 31, 2020. At March 31, 2020, the operating lease had a weighted-average remaining term of 9 years and a weighted-average discount rate of 3.25%. The lease includes an option to extend the lease term by 5 years. Like-Kind Exchange Agreements Periodically, we enter into like-kind exchange agreements upon the disposition or acquisition of certain properties. Pursuant to the terms of these agreements, the proceeds from the sales are placed into an escrow account administered by a qualified intermediary and are unavailable for our use until released. The proceeds are recorded as restricted cash on our consolidated balance sheets and released (i) if they are utilized as part of a like-kind exchange agreement, (ii) if we do not identify a suitable replacement property within 45 days after the agreement date, or (iii) when a like-kind exchange agreement is not completed within the remaining allowable time period.

Debt Disclosure [Abstract]
DEBT	DEBT Long-term debt was $2,982 million and $2,984 million at March 31, 2021 and December 31, 2020, respectively. Revolving Credit Facility —During the three months ended March 31, 2021, we entered into a Third Amendment to the Second Amended and Restated Credit Agreement (the "Revolver Amendment"). The Revolver Amendment (i) extended the current covenant relief period through January 1, 2022 (the "Covenant Relief Period"), (ii) added a new minimum fixed charge coverage ratio covenant applicable to the first quarter of 2022, and (iii) increased the maintenance level of the leverage ratio covenant for the second, third, fourth and fifth quarters following the end of the Covenant Relief Period. The Revolver Amendment also included an option, at our election, to extend the maturity date of $1.45 billion of revolving credit commitments by one year on the terms specified in the Revolver Amendment. The terms of the Revolver Amendment restrict, among other things, our ability to repurchase shares and pay dividends until the first quarter of 2022. The $1.5 billion aggregate commitment amount under our revolving credit facility remains unchanged. During the three months ended March 31, 2021, we had no borrowings or repayments on our revolving credit facility. During the three months ended March 31, 2020, we had $400 million of borrowings and $50 million of repayments on our revolving credit facility. The weighted-average interest rate on these borrowings was 1.66% at March 31, 2020. At both March 31, 2021 and December 31, 2020, we had no balance outstanding. At March 31, 2021, we had $1,499 million of borrowing capacity available under our revolving credit facility, net of letters of credit outstanding. Fair Value —We estimated the fair value of debt, excluding finance lease obligations, which consists of the notes below, collectively referred to as the "Senior Notes," bonds, and other long-term debt. • $250 million of 5.375% senior notes due 2021 (the "2021 Notes") • $750 million of three-month LIBOR plus 3.000% senior notes due 2022 (the "2022 Notes") • $350 million of 3.375% senior notes due 2023 (the "2023 Notes") • $450 million of 5.375% senior notes due 2025 (the "2025 Notes") • $400 million of 4.850% senior notes due 2026 (the "2026 Notes") • $400 million of 4.375% senior notes due 2028 (the "2028 Notes") • $450 million of 5.750% senior notes due 2030 (the "2030 Notes") Our Senior Notes and bonds are classified as Level Two due to the use and weighting of multiple market inputs in the final price of the security. We estimated the fair value of other debt instruments using a discounted cash flow analysis based on current market inputs for similar types of arrangements. Based on the lack of available market data, we have classified our revolving credit facility and other debt instruments as Level Three. The primary sensitivity in these models is based on the selection of appropriate discount rates. Fluctuations in our assumptions will result in different estimates of fair value. March 31, 2021 Carrying value Fair value Quoted prices in active markets for identical assets (Level One) Significant other observable inputs (Level Two) Significant unobservable inputs (Level Three) Debt (1) $ 3,257 $ 3,499 $ — $ 3,461 $ 38 (1) Excludes $9 million of finance lease obligations and $24 million of unamortized discounts and deferred financing fees.

Interest Rate Locks —At both March 31, 2021 and December 31, 2020, we had no outstanding interest rate locks. During the three months ended March 31, 2020, we recognized $34 million of pre-tax losses in unrealized gains (losses) on our condensed consolidated statements of comprehensive loss related to derivative instruments that were settled in April 2020. Upon settlement, we recorded a $61 million loss within accumulated other comprehensive loss. This loss is amortized into interest expense on our condensed consolidated statements of income (loss) over the term of the 2030 Notes and resulted in $2 million of interest expense recognized during the three months ended March 31, 2021 (see Note 13).

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESThe effective income tax rates for the three months ended March 31, 2021 and March 31, 2020 were (156.6)% and 25.4%, respectively. Our effective tax rate decreased for the three months ended March 31, 2021, compared to the three months ended March 31, 2020, due to a $193 million non-cash expense to record a full valuation allowance on U.S. federal and state deferred tax assets and the impact of unbenefited U.S. and foreign losses in the period. During the year ended December 31, 2020 and the three months ended March 31, 2021, we generated significant pre-tax losses driven by the COVID-19 pandemic business disruption, and during the three months ended March 31, 2021, we entered into a three-year cumulative U.S. pre-tax loss position. When assessing the need for a valuation allowance against our deferred tax assets, we considered both positive and negative evidence, including the cumulative three-year pre-tax loss position. We considered sources of positive evidence including recent favorable recovery trends in the hospitality industry in the first quarter of 2021 and the indefinite carryforward period of U.S. tax losses generated. Accounting Standards Codification 740, Income Taxes , prescribes that a recent cumulative pre-tax loss position is strong objectively verifiable negative evidence that is difficult to overcome and little or no weight is placed on future projections of pre-tax income, and therefore, our forecasts did not have an impact on our assessment. Based on the weight of all available evidence, we recorded a full valuation allowance against our U.S. deferred tax assets. During the three months ended March 31, 2021, we recognized a $193 million valuation allowance for U.S. federal and state deferred tax assets. At January 1, 2021, we had no U.S. federal net operating loss carryforwards, as the net operating losses we generated in 2020 were carried back to prior years, as described below. To measure the valuation allowance, we estimated the years in which our deferred tax assets and liabilities would reverse using systematic and logical methods to determine reversal patterns. If we continue to generate losses in future periods, additional valuation allowances may be required that could have an adverse impact on our net income (loss). Conversely, if pre-tax income returns to normalized levels, we expect to see these allowances reverse, which would result in an increase in reported net income. We will continue to reassess the realizability of our U.S. deferred tax asset balances in future periods. During the three months ended March 31, 2021, we filed a U.S. refund claim, which carried back the taxable loss generated in 2020 to 2015, 2016, and 2017 as allowed under the provision of the Coronavirus Aid, Relief, and Economic Security Act. As a result, we expect a refund from the Internal Revenue Service ("IRS") of approximately $250 million, which is recorded in prepaid income taxes on our condensed consolidated balance sheets. We are subject to audits by federal, state, and foreign tax authorities. U.S. tax years 2009 through 2011 are before the U.S. Tax Court concerning the tax treatment of the loyalty program. We are currently under field exam by the IRS for tax years 2015 through 2017. During the three months ended March 31, 2021, we received a Notice of Proposed Adjustment for those tax years related to the loyalty program issue currently in U.S. Tax Court. As a result, U.S. tax years 2009 through 2017 are pending the outcome of the issue currently in U.S. Tax Court. If the IRS' position to include loyalty program contributions as taxable income to the Company is upheld, it would result in an income tax payment of $218 million (including $60 million of estimated interest, net of federal tax benefit) for all assessed years. We believe we have an adequate uncertain tax liability recorded in connection with this matter. At March 31, 2021 and December 31, 2020, total unrecognized tax benefits recorded in other long-term liabilities on our condensed consolidated balance sheets were $147 million and $146 million, respectively, of which $138 million and $49 million, respectively, would impact the effective tax rate if recognized.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES In the ordinary course of business, we enter into various commitments, guarantees, surety bonds, and letter of credit agreements. Commitments —At March 31, 2021, we are committed, under certain conditions, to lend or provide certain consideration to, or invest in, various business ventures up to $335 million, net of any related letters of credit. Performance Guarantees —Certain of our contractual agreements with third-party hotel owners require us to guarantee payments to the owners if specified levels of operating profit are not achieved by their hotels. At March 31, 2021, the remaining maximum exposure under our performance guarantees was $41 million. Our most significant performance guarantee, relating to four managed hotels in France, expired on April 30, 2020. We had $14 million and $16 million of total performance guarantee liabilities at March 31, 2021 and December 31, 2020, respectively, which included $6 million recorded in other long-term liabilities for both periods and $8 million and $10 million recorded in accrued expenses and other current liabilities on our condensed consolidated balance sheets, respectively.

If we choose not to fund the shortfall, the hotel owner has the option to terminate the management contract. At March 31, 2021 and December 31, 2020, we had $4 million and $3 million, respectively, recorded in accrued expenses and other current liabilities on our condensed consolidated balance sheets related to these performance cure payments. Debt Repayment and Other Guarantees —We enter into various debt repayment and other guarantees in order to assist hotel owners and unconsolidated hospitality ventures in obtaining third-party financing or to obtain more favorable borrowing terms. Property description Maximum potential future payments Maximum exposure net of recoverability from third parties Other long-term liabilities recorded at March 31, 2021 Other long-term liabilities recorded at December 31, 2020 Year of guarantee expiration Hotel properties in India (1) $ 170 $ 170 $ — $ — 2021 Hotel properties in Tennessee (2) 56 26 7 8 various, through 2024 Hotel properties in California (2) 38 15 2 2 2021 Hotel property in Pennsylvania (2), (3) 28 11 1 1 various, through 2023 Hotel property in Massachusetts (2), (3) 27 14 3 4 various, through 2022 Hotel properties in Georgia (2) 27 13 3 4 various, through 2024 Hotel property in Oregon (2) 21 8 1 1 2022 Other (2), (4) 21 8 3 5 various, through 2025 Total $ 388 $ 265 $ 20 $ 25 (1) Debt repayment guarantee is denominated in Indian rupees and translated using exchange rates at March 31, 2021. We have the contractual right to recover amounts funded from an unconsolidated hospitality venture, which is a related party. We expect our maximum exposure to be $85 million, taking into account our partner's 50% ownership interest in the unconsolidated hospitality venture. Under certain events or conditions, we have the right to force the sale of the properties in order to recover amounts funded. (2) We have agreements with our unconsolidated hospitality venture partners, the respective hotel owners, or other third parties to recover certain amounts funded under the debt repayment guarantee; the recoverability mechanism may be in the form of cash or HTM debt security. (3) In conjunction with the debt repayment guarantees, we are subject to completion guarantees whereby the parties agree to substantially complete the construction of the project by a specified date. In the event of default, we are obligated to complete construction using the funds available from the outstanding loan. Any additional funds paid by us are subject to partial recovery in the form of cash. At March 31, 2021, the maximum potential future payments and the maximum exposure net of recoverability from third parties are insignificant. (4) If certain funding thresholds are met or if certain events occur, we have the ability to assume control of the property. At March 31, 2021, we are not aware of, nor have we received notification that our unconsolidated hospitality ventures or hotel owners are not current on their debt service obligations where we have provided a debt repayment guarantee. Guarantee Liabilities Fair Value —We estimated the fair value of our guarantees to be $44 million and $66 million at March 31, 2021 and December 31, 2020, respectively. Based on the lack of available market data, we have classified our guarantees as Level Three in the fair value hierarchy. Insurance —We obtain commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, crime, property, cyber risk, and other miscellaneous coverages. A portion of the risk is retained on a self-insurance basis primarily through a U.S.-based and licensed captive insurance company that is a wholly owned subsidiary of Hyatt and generally insures our deductibles and retentions. Reserve requirements are established based on actuarial projections of ultimate losses. Reserves for losses in our captive insurance company to be paid within 12 months are $36 million and $37 million at March 31, 2021 and December 31, 2020, respectively, and are recorded in accrued expenses and other current liabilities on our condensed consolidated balance sheets. Reserves for losses in our captive insurance company to be paid in future periods are $67 million at both March 31, 2021 and December 31, 2020 and are recorded in other long-term liabilities on our condensed consolidated balance sheets. Collective Bargaining Agreements —At March 31, 2021, approximately 26% of our U.S.-based employees were covered by various collective bargaining agreements, generally providing for basic pay rates, working hours, other conditions of employment, and orderly settlement of labor disputes. Certain employees are covered by union-sponsored, multi-employer pension and health plans pursuant to agreements between us and various unions. Generally, labor relations have been maintained in a normal and satisfactory manner, and we believe our employee relations are good. Surety Bonds —Surety bonds issued on our behalf were $49 million at March 31, 2021 and primarily relate to workers' compensation, taxes, licenses, construction liens, and utilities related to our lodging operations. Letters of Credit —Letters of credit outstanding on our behalf at March 31, 2021 were $238 million, which relate to our ongoing operations, hotel properties under development in the U.S., collateral for estimated insurance claims, and securitization of our performance under our debt repayment guarantee associated with the hotel properties in India, which is only called on if we default on our guarantee. Of the letters of credit outstanding, $1 million reduces the available capacity under our revolving credit facility (see Note 9). Capital Expenditures —As part of our ongoing business operations, expenditures are required to complete renovation projects that have been approved. Other —We act as general partner of various partnerships owning hotel properties that are subject to mortgage indebtedness. These mortgage agreements generally limit the lender's recourse to security interests in assets financed and/or other assets of the partnership(s) and/or the general partner(s) thereof. In conjunction with financing obtained for our unconsolidated hospitality ventures and certain managed hotels, we may provide standard indemnifications to the lender for loss, liability, or damage occurring as a result of our actions or actions of the other unconsolidated hospitality venture partners or respective hotel owners. As a result of certain dispositions, we have agreed to provide customary indemnifications to third-party purchasers for certain liabilities incurred prior to sale and for breach of certain representations and warranties made during the sales process, such as representations of valid title, authority, and environmental issues that may not be limited by a contractual monetary amount. These indemnification agreements survive until the applicable statutes of limitation expire or until the agreed upon contract terms expire. We are subject, from time to time, to various claims and contingencies related to lawsuits, taxes, and environmental matters, as well as commitments under contractual obligations. Many of these claims are covered under our current insurance programs, subject to deductibles. Although the ultimate liability for these matters cannot be determined at this point, based on information currently available, we do not expect the ultimate resolution of such claims and litigation to have a material effect on our condensed consolidated financial statements. During the year ended December 31, 2018, we received a notice from the Indian tax authorities assessing additional service tax on our operations in India. We appealed this decision and do not believe a loss is probable, and therefore, we have not recorded a liability in connection with this matter. At March 31, 2021, our maximum exposure is not expected to exceed $18 million.

These repurchases may be made from time to time in the open market, in privately negotiated transactions, or otherwise, including pursuant to a Rule 10b5-1 plan or an accelerated share repurchase transaction, at prices we deem appropriate and subject to our financial condition, capital requirements, market conditions, restrictions under the terms of our revolving credit facility, applicable law, and other factors deemed relevant in our sole discretion. The common stock repurchase program applies to our Class A and Class B common stock. The common stock repurchase program does not obligate us to repurchase any dollar amount or number of shares of common stock, and the program may be suspended or discontinued at any time. During the three months ended March 31, 2021, we did not repurchase common stock. During the three months ended March 31, 2020, we repurchased 827,643 shares of Class A common stock. The shares of common stock were repurchased at a weighted-average price of $84.08 per share for an aggregate purchase price of $69 million, excluding related insignificant expenses. The shares repurchased during the three months ended March 31, 2020 represented approximately 1% of our total shares of common stock outstanding at December 31, 2019. The shares of Class A common stock repurchased on the open market were retired and returned to the status of authorized and unissued shares. At March 31, 2021, we had $928 million remaining under the share repurchase authorization. Dividend — Hyatt did not declare or pay dividends to Class A or Class B shareholders of record during the three months ended March 31, 2021. On February 13, 2020, our board of directors declared a cash dividend of $0.20 per share for the first quarter of 2020, which was paid on March 9, 2020 to Class A and Class B shareholders of record on February 26, 2020. For the three months ended March 31, 2020, $7 million and $13 million of cash dividends were paid for Class A and Class B common stock, respectively.

Share-based Payment Arrangement, Noncash Expense [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION As part of our Long-Term Incentive Plan ("LTIP"), we award time-vested stock appreciation rights ("SARs"), time-vested restricted stock units ("RSUs"), and performance-vested restricted stock units ("PSUs") to certain employees and non-employee directors. In addition, non-employee directors may elect to receive their annual fees and/or annual equity retainers in the form of shares of our Class A common stock. Compensation expense and unearned compensation presented below exclude amounts related to employees of our managed hotels and other employees whose payroll is reimbursed, as this expense has been and will continue to be reimbursed by our third-party hotel owners and is recognized within revenues for the reimbursement of costs incurred on behalf of managed and franchised properties and costs incurred on behalf of managed and franchised properties on our condensed consolidated statements of income (loss). Stock-based compensation expense recognized in selling, general, and administrative expenses on our condensed consolidated statements of income (loss) related to these awards was as follows: Three Months Ended March 31, 2021 2020 SARs $ 9 $ 10 RSUs 13 10 PSUs 6 (5) Total $ 28 $ 15 The three months ended March 31, 2020 included a reversal of previously recognized stock-based compensation expense based on our assessment at the time of the expected achievement relative to the applicable performance targets related to certain PSU awards. SARs —During the three months ended March 31, 2021, we granted 396,889 SARs to employees with a weighted-average grant date fair value of $28.68. During the three months ended March 31, 2020, we granted 1,250,434 SARs to employees with a weighted-average grant date fair value of $8.88. RSUs —During the three months ended March 31, 2021, we granted 388,726 RSUs to employees and non-employee directors with a weighted-average grant date fair value of $80.48. During the three months ended March 31, 2020, we granted 519,730 RSUs to employees with a weighted-average grant date fair value of $48.66. PSUs —During the three months ended March 31, 2021, we granted 153,256 PSUs to employees with a weighted-average grant date fair value of $82.02. During the three months ended March 31, 2020, we did not grant any PSUs under our LTIP. Our total unearned compensation for our stock-based compensation programs at March 31, 2021 was $3 million for SARs, $25 million for RSUs, and $23 million for PSUs, which will primarily be recognized in stock-based compensation expense over a weighted-average period of three years.

Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS In addition to those included elsewhere in the Notes to our condensed consolidated financial statements, related-party transactions entered into by us are summarized as follows: Equity Method Investments —We have equity method investments in entities that own, operate, manage, or franchise properties for which we receive management, franchise, or license fees. We recognized $1 million and $3 million of fees for the three months ended March 31, 2021 and March 31, 2020, respectively. In addition, in some cases we provide loans (see Note 5) or guarantees (see Note 12) to these entities. During each of the three months ended March 31, 2021 and March 31, 2020, we recognized $1 million of income related to these guarantees. At March 31, 2021 and December 31, 2020, we had $15 million of receivables due from these properties. Our ownership interest in these unconsolidated hospitality ventures varies from 24% to 50%. See Note 4 for further details regarding these investments. Class B Share Conversion —During the three months ended March 31, 2021, 800,169 shares of Class B common stock were converted on a share-for-share basis into shares of Class A common stock, $0.01 par value per share. The shares of Class B common stock that were converted into shares of Class A common stock have been retired, thereby reducing the shares of Class B common stock authorized and outstanding.

SEGMENT INFORMATION

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Our reportable segments are components of the business which are managed discretely and for which discrete financial information is reviewed regularly by the chief operating decision maker ("CODM") to assess performance and make decisions regarding the allocation of resources. Our CODM is our President and Chief Executive Officer. We define our reportable segments as follows: • Owned and leased hotels —This segment derives its earnings from owned and leased hotel properties located predominantly in the United States but also in certain international locations, and for purposes of segment Adjusted EBITDA, includes our pro rata share of the Adjusted EBITDA of our unconsolidated hospitality ventures, based on our ownership percentage of each venture. Adjusted EBITDA includes intercompany expenses related to management fees paid to the Company's management and franchising segments, which are eliminated in consolidation. Intersegment revenues relate to promotional award redemptions earned by our owned and leased hotels related to our co-branded credit card program and are eliminated in consolidation. • Americas management and franchising —This segment derives its earnings primarily from a combination of hotel management and licensing of our portfolio of brands to franchisees located in the United States, Latin America, Canada, and the Caribbean as well as revenues from residential management operations. This segment's revenues also include the reimbursement of costs incurred on behalf of managed and franchised properties. These reimbursed costs relate primarily to payroll at managed properties where the Company is the employer, as well as costs associated with sales, reservations, technology, and marketing services (collectively, "system-wide services") and the loyalty program operated on behalf of owners of managed and franchised properties. The intersegment revenues relate to management fees earned from the Company's owned and leased hotels and are eliminated in consolidation. • ASPAC management and franchising —This segment derives its earnings primarily from a combination of hotel management and licensing of our portfolio of brands to franchisees located in Southeast Asia, Greater China, Australia, New Zealand, South Korea, Japan, and Micronesia. This segment's revenues also include the reimbursement of costs incurred on behalf of managed and franchised properties. These reimbursed costs relate primarily to system-wide services and the loyalty program operated on behalf of owners of managed and franchised properties. • EAME/SW Asia management and franchising —This segment derives its earnings primarily from a combination of hotel management and licensing of our portfolio of brands to franchisees located in Europe, Africa, the Middle East, India, Central Asia, and Nepal. This segment's revenues also include the reimbursement of costs incurred on behalf of managed and franchised properties. These reimbursed costs relate primarily to system-wide services and the loyalty program operated on behalf of owners of managed and franchised properties. The intersegment revenues relate to management fees earned from the Company's owned and leased hotels and are eliminated in consolidation. Our CODM evaluates performance based on owned and leased hotels revenues; management, franchise, and other fees revenues; and Adjusted EBITDA. Adjusted EBITDA, as we define it, is a non-GAAP measure. We define Adjusted EBITDA as net income (loss) attributable to Hyatt Hotels Corporation plus our pro rata share of unconsolidated owned and leased hospitality ventures' Adjusted EBITDA based on our ownership percentage of each owned and leased venture, adjusted to exclude interest expense; benefit (provision) for income taxes; depreciation and amortization; amortization of management and franchise agreement assets and performance cure payments, which constitute payments to customers ("Contra revenue"); revenues for the reimbursement of costs incurred on behalf of managed and franchised properties; costs incurred on behalf of managed and franchised properties that we intend to recover over the long term; equity earnings (losses) from unconsolidated hospitality ventures; stock-based compensation expense; gains (losses) on sales of real estate; asset impairments; and other income (loss), net. The table below shows summarized consolidated financial information by segment. Included within corporate and other are results from our co-branded credit card program, the results of the Exhale spa and fitness business, which was sold during the year ended December 31, 2020, and unallocated corporate expenses.

RECENTLY ISSUED ACCOUNTING PR_2

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information, the instructions to Form 10-Q, and Article 10 of Regulation S-X. Accordingly, they do not include all information or footnotes required by GAAP for complete annual financial statements.
Principles of Consolidation	We have eliminated all intercompany accounts and transactions in our condensed consolidated financial statements. We consolidate entities under our control, including entities where we are deemed to be the primary beneficiary.
Future Adoption of Accounting Standards	Future Adoption of Accounting Standards Reference Rate Reform —In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update No. 2020-04 ("ASU 2020-04"), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 provides optional expedients and exceptions that we can elect to adopt, subject to meeting certain criteria, regarding contract modifications, hedging relationships, and other transactions that reference the London Inter-bank Offered Rate for deposits of U.S. dollars ("LIBOR") or another reference rate expected to be discontinued by June 30, 2023 because of reference rate reform. The provisions of ASU 2020-04 are only available through December 31, 2022. We are currently assessing the impact of adopting ASU 2020-04.
Revenue Recognition	Revenue Allocated to Remaining Performance ObligationsRevenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods.
Self Insurance	We obtain commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, crime, property, cyber risk, and other miscellaneous coverages. A portion of the risk is retained on a self-insurance basis primarily through a U.S.-based and licensed captive insurance company that is a wholly owned subsidiary of Hyatt and generally insures our deductibles and retentions. Reserve requirements are established based on actuarial projections of ultimate losses.
Commitments and Contingencies Other	We act as general partner of various partnerships owning hotel properties that are subject to mortgage indebtedness. These mortgage agreements generally limit the lender's recourse to security interests in assets financed and/or other assets of the partnership(s) and/or the general partner(s) thereof. In conjunction with financing obtained for our unconsolidated hospitality ventures and certain managed hotels, we may provide standard indemnifications to the lender for loss, liability, or damage occurring as a result of our actions or actions of the other unconsolidated hospitality venture partners or respective hotel owners. As a result of certain dispositions, we have agreed to provide customary indemnifications to third-party purchasers for certain liabilities incurred prior to sale and for breach of certain representations and warranties made during the sales process, such as representations of valid title, authority, and environmental issues that may not be limited by a contractual monetary amount. These indemnification agreements survive until the applicable statutes of limitation expire or until the agreed upon contract terms expire. We are subject, from time to time, to various claims and contingencies related to lawsuits, taxes, and environmental matters, as well as commitments under contractual obligations. Many of these claims are covered under our current insurance programs, subject to deductibles. Although the ultimate liability for these matters cannot be determined at this point, based on information currently available, we do not expect the ultimate resolution of such claims and litigation to have a material effect on our condensed consolidated financial statements.
Segment Reporting	Our reportable segments are components of the business which are managed discretely and for which discrete financial information is reviewed regularly by the chief operating decision maker ("CODM") to assess performance and make decisions regarding the allocation of resources.
