Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Description of Business Expedia Group, Inc. and its subsidiaries provide travel products and services to leisure and corporate travelers in the United States and abroad as well as various media and advertising offerings to travel and non-travel advertisers. These travel products and services are offered through a diversified portfolio of brands including: Brand Expedia®, Hotels.com®, Expedia® Partner Solutions, Vrbo®, trivago®, Orbitz®, Travelocity®, Hotwire®, Wotif®, ebookers®, CheapTickets®, Expedia Group™ Media Solutions, CarRentals.com™, Expedia Cruises TM and Traveldoo®. In addition, many of these brands have related international points of sale. We refer to Expedia Group, Inc. and its subsidiaries collectively as “Expedia Group,” the “Company,” “us,” “we” and “our” in these consolidated financial statements. COVID-19 The COVID-19 pandemic, and measures to contain the virus, including government travel restrictions and quarantine orders, have had a significant negative impact on the global travel industry and materially and negatively impacted our business, financial results and financial condition. Since the first quarter of 2020, COVID-19 has negatively impacted consumer sentiment and consumer’s ability to travel, and many of our supply partners, particularly airlines and hotels, continue to operate at reduced but improving service levels in 2022. More recently, travel trends have continued to improve. Overall, the full duration and total impact of COVID-19 remains uncertain and it is difficult to predict how the recovery will unfold for the travel industry and, in particular, our business, going forward. Basis of Presentation These accompanying financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited consolidated financial statements include Expedia Group, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We record our investments in entities that we do not control, but over which we have the ability to exercise significant influence, using the equity method or at fair value. We have eliminated significant intercompany transactions and accounts. We have prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. We have included all adjustments necessary for a fair presentation of the results of the interim period. These adjustments consist of normal recurring items. Our interim unaudited consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2021, previously filed with the Securities and Exchange Commission (“SEC”). trivago is a separately listed company on the Nasdaq Global Select Market and, therefore is subject to its own reporting and filing requirements, which could result in possible differences that are not expected to be material to Expedia Group. Accounting Estimates We use estimates and assumptions in the preparation of our interim unaudited consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our interim unaudited consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited consolidated financial statements include revenue recognition; recoverability of current and long-lived assets, intangible assets and goodwill; income and transactional taxes, such as potential settlements related to occupancy and excise taxes; loss contingencies; deferred loyalty rewards; stock-based compensation; accounting for derivative instruments and provisions for credit losses, customer refunds and chargebacks. The COVID-19 pandemic has created and may continue to create significant uncertainty in macroeconomic conditions, which may cause further business disruptions and adversely impact our results of operations. As a result, many of our estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods. Reclassifications We have reclassified prior period financial statements to conform to the current period presentation. Seasonality We generally experience seasonal fluctuations in the demand for our travel services. For example, traditional leisure travel bookings are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. The number of bookings typically decreases in the fourth quarter. Since revenue for most of our travel services, including merchant and agency hotel, is recognized as the travel takes place rather than when it is booked, revenue typically lags bookings by several weeks for our hotel business and can be several months or more for our alternative accommodations business. Historically, Vrbo has seen seasonally stronger bookings in the first quarter of the year, with the relevant stays occurring during the peak summer travel months. The seasonal revenue impact is exacerbated with respect to income by the nature of our variable cost of revenue and direct sales and marketing costs, which we typically realize in closer alignment to booking volumes, and the more stable nature of our fixed costs. Furthermore, operating profits for our primary advertising business, trivago, have typically been experienced in the second half of the year, particularly the fourth quarter, as selling and marketing costs offset revenue in the first half of the year as we typically increase marketing during the busy booking period for spring, summer and winter holiday travel. As a result on a consolidated basis, revenue and income are typically the lowest in the first quarter and highest in the third quarter. The growth of our international operations, advertising business or a change in our product mix, including the growth of Vrbo, may influence the typical trend of seasonality in the future. Impacts from COVID-19 disrupted our typical seasonal pattern for bookings, revenue, profit and cash flows during 2020 and 2021. Significantly higher cancellations and reduced booking volumes, particularly in the first half of 2020, resulted in material operating losses and negative cash flow. Booking and travel trends improved in the second half of 2020, throughout 2021, and in the first nine months of 2022. This has resulted in working capital benefits and positive cash flow more akin to typical historical trends. It remains difficult to forecast the seasonality for upcoming quarters, given the uncertainty related to the shape and timing of any sustained recovery.

Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Recent Adopted Accounting Policies In June 2022, the Financial Accounting Standards Board (“FASB”) issued new guidance related to fair value measurement of equity securities, which clarifies the fair value measurement of an equity security that is subject to a contractual sale restriction and requires specific disclosures related to such an equity security. The new guidance is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. We elected to early adopt the new guidance in the second quarter of 2022 on a prospective basis. One of our minority equity investments is accounted for in accordance with this new guidance. See Note 3 – Fair Value Measurements for additional information. Recent Accounting Policies Not Yet Adopted In October 2021, the FASB issued new guidance relate to recognizing and measuring contract assets and contract liabilities from contracts with customers acquired in a business combination. The new guidance will require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination as compared to current GAAP where an acquirer generally recognizes such items at fair value on the acquisition date. The new guidance is effective on a prospective basis for fiscal years beginning after December 15, 2022, with early adoption permitted. We do not expect it will have a material impact, if any, on our consolidated financial statements. Significant Accounting Policies Below are the significant accounting policies with interim disclosure requirements. For a comprehensive description of our accounting policies, refer to our Annual Report on Form 10-K for the year ended December 31, 2021. Revenue Prepaid Merchant Bookings. We classify payments made to suppliers in advance of Vrbo performance obligations as prepaid merchant bookings included within prepaid and other current assets. Prepaid merchant bookings was $522 million as of September 30, 2022 and $591 million as of December 31, 2021. Deferred Merchant Bookings. We classify cash payments received in advance of our performance obligations as deferred merchant bookings. At December 31, 2021, $4.9 billion of advance cash payments was reported within deferred merchant bookings, $4.2 billion of which was recognized resulting in $686 million of revenue during the nine months ended September 30, 2022. At September 30, 2022, the related balance was $6.5 billion. At December 31, 2021, $798 million of deferred loyalty rewards was reported within deferred merchant bookings, $575 million of which was recognized within revenue during the nine months ended September 30, 2022. At September 30, 2022, the related balance was $915 million. Deferred Revenue. At December 31, 2021, $166 million was recorded as deferred revenue, $109 million of which was recognized as revenue during the nine months ended September 30, 2022. At September 30, 2022, the related balance was $160 million. Practical Expedients and Exemptions. We have used the portfolio approach to account for our loyalty points as the rewards programs share similar characteristics within each program in relation to the value provided to the traveler and their breakage patterns. Using this portfolio approach is not expected to differ materially from applying the guidance to individual contracts. However, we will continue to assess and refine, if necessary, how a portfolio within each rewards program is defined. We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. Cash, Restricted Cash, and Cash Equivalents Our cash and cash equivalents include cash and liquid financial instruments, including U.S. treasury securities, money market funds and term deposit investments, with maturities of three months or less when purchased. Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or our intention to use the cash for a specific purpose. Our restricted cash relates to certain traveler deposits, primarily for Vrbo, and to a lesser extent collateral for office leases. The following table reconciles cash, cash equivalents and restricted cash reported in our consolidated balance sheets to the total amount presented in our consolidated statements of cash flows: September 30, December 31, (in millions) Cash and cash equivalents $ 4,588 $ 4,111 Restricted cash and cash equivalents 1,778 1,694 Total cash, cash equivalents and restricted cash and cash equivalents in the consolidated statements of cash flows $ 6,366 $ 5,805 Accounts Receivable and Allowances

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2022 are classified using the fair value hierarchy in the table below: Total Level 1 Level 2 (In millions) Assets Cash equivalents: Money market funds $ 4 $ 4 $ — Term deposits 184 — 184 Derivatives: Foreign currency forward contracts 29 — 29 Cross-currency interest rate swaps 42 — 42 Investments: Term deposits 49 — 49 Equity investments 486 55 431 Total assets $ 794 $ 59 $ 735 Financial assets measured at fair value on a recurring basis as of December 31, 2021 are classified using the fair value hierarchy in the table below: Total Level 1 Level 2 Level 3 (In millions) Assets Cash equivalents: Money market funds $ 47 $ 47 $ — $ — Mutual funds 23 23 — — Term deposits 153 — 153 — Derivatives: Foreign currency forward contracts 3 — 3 — Investments: Term deposits 200 — 200 — Equity investments 909 94 — 815 Total assets $ 1,335 $ 164 $ 356 $ 815 We classify our cash equivalents and investments within Level 1 and Level 2 as we value our cash equivalents and investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Valuation of the foreign currency forward contracts is based on foreign currency exchange rates in active markets, a Level 2 input. Valuation of the cross-currency interest rate swaps is based on foreign currency exchange rates and the current interest rate curve, Level 2 inputs. We hold term deposit investments with financial institutions. Term deposits with original maturities of less than three months are classified as cash equivalents, those with remaining maturities of less than one year are classified within short-term investments and those with remaining maturities of greater than one year are classified within long-term investments and other assets. As of September 30, 2022 and December 31, 2021, our cash and cash equivalents consisted primarily of term deposits, money market funds and mutual funds with maturities of three months or less and bank account balances. We use foreign currency forward contracts to economically hedge certain merchant revenue exposures, foreign denominated liabilities related to certain of our loyalty programs and our other foreign currency-denominated operating liabilities. Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. Our foreign currency forward contracts are typically short-term and, as they do not qualify for hedge accounting treatment, we classify the changes in their fair value in other, net. As of September 30, 2022, we were party to outstanding forward contracts hedging our liability exposures with a total net notional value of $2.3 billion. We had a net forward asset of $29 million ($47 million gross asset) as of September 30, 2022 and a net forward asset of $3 million ($12 million gross asset) as of December 31, 2021 recorded in prepaid expenses and other current assets. We recorded $(60) million and $15 million in net gains (losses) from foreign currency forward contracts during the three months ended September 30, 2022 and 2021 as well as $144 million and $8 million in net losses from foreign currency forward contracts during the nine months ended September 30, 2022 and 2021. On March 2, 2022, we entered into two fixed-to-fixed cross-currency interest rate swaps with an aggregate notional amount of €300 million. The swaps were designated as net investment hedges of Euro assets with the objective to protect the U.S. dollar value of our net investments in the Euro foreign operations due to movements in foreign currency. Hedge effectiveness is assessed each quarter based on the net investment in the foreign subsidiaries designated as the hedged item and the changes in the fair value of designated interest rate swaps based on spot rates. For hedges that meet the effectiveness requirements, changes in fair value are recorded as accumulated other comprehensive income (loss) (“AOCI”) within the foreign currency translation adjustment. Amounts excluded from hedge effectiveness at inception are recognized as interest accrues within interest expense. The maturity date of both swaps is February 2026, whereby, we will receive U.S. dollars from and pay Euros to the contract counterparties. During the term of each contract, we receive interest payments in U.S. dollars at a fixed rate of 5% and make interest payments in Euros at an average fixed rate of 3.38% based on a notional amount and fixed interest rates determined at contract inception. The fair value of the cross-currency interest rate swaps was a $42 million asset as of September 30, 2022 recorded in long-term investments and other assets, and the gain recognized in interest expense during the nine months ended September 30, 2022 was $4 million. Our equity investments include our marketable equity investment in Despegar, a publicly traded company, which is included in long-term investments and other assets in our consolidated balance sheets. During the nine months ended September 30, 2022 and 2021, we recognized a loss of approximately $39 million and approximately $7 million within other, net in our consolidated statements of operations related to the fair value changes of this equity investment. In connection with our disposition of Egencia (our former corporate travel arm) in November 2021, we became an indirect holder of an approximately 19% interest in GBT JerseyCo Ltd. (“GBT”), doing business as American Express Global Business Travel, with an initial fair value of $815 million. As we elected the fair value option for our investment, during the first quarter of 2022, we recorded a downward adjustment of approximately $2 million based on an updated valuation. In May 2022, GBT completed a deSPAC business combination with Apollo Strategic Growth Capital. This combination resulted in a newly publicly traded company, Global Business Travel Group, Inc (“GBTG”), which together with GBT’s pre-combination shareholders owned all of GBT. Post combination and as of September 30, 2022, we had an approximately 16% ownership interest in GBT and a commensurate voting interest in GBTG. Our shares in GBT are exchangeable on a 1:1 basis for GBTG shares, and as such, we valued our investment based on the GBTG’s share price at the end of the third quarter of 2022, which resulted in a loss of $48 million within other, net in our consolidated statements of operations during the three months ended September 30, 2022. The loss for the nine months ended September 30, 2022 was $384 million. We are subject to a lockup period on sales of these equity securities until November 23, 2022. The following table reconciles, in millions, the beginning and ending balances of our Level 3 assets. With the May 2022 business combination of GBTG, we reclassified our equity investment from a Level 3 asset to a Level 2 asset. Balance as of December 31, 2021 $ 815 Upward (downward) adjustment to valuation (335) Reclassification to Level 2 (480) Balance as of September 30, 2022 $ — Assets Measured at Fair Value on a Non-recurring Basis Our non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity method investments for which we have not elected the fair value option, are adjusted to fair value when an impairment charge is recognized or the underlying investment is sold. Such fair value measurements are based predominately on Level 3 inputs. We measure our minority investments that do not have readily determinable fair values at cost less impairment, adjusted by observable price changes with changes recorded within other, net on our consolidated statements of operations. Intangible Assets. During the three and nine months ended September 30, 2022, we recognized intangible impairment charges of $52 million and $81 million related to an indefinite-lived trade name within our trivago segment that primarily resulted from changes in the weighted average cost of capital. The indefinite-lived trade name asset, classified as Level 3 measurements, was valued using the relief-from-royalty method, which includes unobservable inputs, including projected revenues, royalty rates and weighted average cost of capital. As noted above, trivago is subject to its own reporting and filing requirements and, therefore, assesses goodwill at a lower level, which could result in possible differences in the ultimate amount or timing of impairments recognized.

Redemption of Senior Notes During the three and nine months ended September 30, 2022, we settled a tender offer to purchase $500 million in aggregate principal of our 2.95% Senior Notes due 2031 for an aggregate cash repurchase price of approximately $418 million, which resulted in the recognition of a net gain on debt extinguishment of $73 million. The net gain included the write-off of debt issuance costs and discounts of $8 million as well as fees of $1 million. During the nine months ended September 30, 2022, we early redeemed all of our €650 million registered senior unsecured notes that were due June 2022 and bore interest at 2.5% (the “2.5% Notes”), all of our $500 million registered senior unsecured notes that were due December 2023 and bore interest at 3.6% (the “3.6% Notes”), and all of our $500 million registered senior unsecured notes that were due August 2024 and bore interest at 4.5% (the “4.5% Notes”), which resulted in the recognition of a loss on debt extinguishment of $24 million during the period. This loss primarily reflected the payment of “make-whole” premiums of $20 million for the 3.6% and 4.5% Notes as well as the write-off of unamortized debt issuance costs and discounts of $4 million. We paid accrued and unpaid interest on the 2.5%, 3.6%, 4.5% and 2.95% Notes up to their dates of redemption. Long-term Debt Additional information about our $1 billion aggregate principal amount of unsecured 0% convertible senior notes due 2026 (the “Convertible Notes”) and our other outstanding senior notes (collectively the “Senior Notes”), s ee Note 8 – Debt of the Notes to Consolidated Financial Statements in our 2021 Form 10-K. All of our outstanding Senior Notes are senior unsecured obligations issued by Expedia Group and guaranteed by certain domestic Expedia Group subsidiaries. The Senior Notes rank equally in right of payment with all of our existing and future unsecured and unsubordinated obligations of Expedia Group and the guarantor subsidiaries. In addition, the Senior Notes include covenants that limit our ability to (i) create certain liens, (ii) enter into sale/leaseback transactions and (iii) merge or consolidate with or into another entity or transfer substantially all of our assets. The Senior Notes are redeemable in whole or in part, at the option of the holders thereof, upon the occurrence of certain change of control triggering events at a purchase price in cash equal to 101% of the principal plus accrued and unpaid interest. Accrued interest related to the Senior Notes was $48 million and $98 million as of September 30, 2022 and December 31, 2021. Estimated Fair Value. The total estimated fair value of our Senior Notes was approximately $4.8 billion and $8.0 billion as of September 30, 2022 and December 31, 2021. Additionally, the estimated fair value of the Convertible Notes was $874 million and $1.2 billion as of September 30, 2022 and December 31, 2021. The fair value was determined based on quoted market prices in less active markets and is categorized according as Level 2 in the fair value hierarchy. Credit Facility As of September 30, 2022, Expedia Group maintained a $2.5 billion revolving credit facility that matures in April 2027. As of September 30, 2022, we had no revolving credit facility borrowings outstanding. Loans under the revolving credit facility bear interest at a rate equal to an index rate plus a margin (a) in the case of term benchmark loans, ranging from 1.00% to 1.75% per annum, depending on Expedia Group’s credit ratings, and (b) in the case of base rate loans, ranging from 0.00% to 0.75% per annum, depending on Expedia Group’s credit ratings. A fee is payable quarterly in respect of undrawn commitments under the revolving credit facility at a rate ranging from 0.10% to 0.25% per annum, depending on Expedia Group’s credit ratings. The terms of the revolving credit facility require Expedia Group to not exceed a specified maximum consolidated leverage ratio as of the end of each fiscal quarter. The revolving credit facility has a $120 million letter of credit (“LOC”) sublimit, and the amount of LOCs issued under the facility reduced the credit amount available. As of September 30, 2022, there was $38 million of outstanding stand-by LOCs issued under the facility. The current facility was setup in April 2022 and Expedia Group terminated all outstanding commitments and repaid all outstanding obligations under our prior $1.145 billion revolving credit facility and $855 million foreign credit facility. As of December 31, 2021, we had no borrowings outstanding under either prior facility and $14 million of outstanding stand-by LOCs issued under the $1.145 billion revolving facility.

The earnings per share amounts are the same for common stock and Class B common stock because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. Diluted earnings per share is calculated using our weighted-average outstanding common shares including the dilutive effect of stock awards and common stock warrants as determined under the treasury stock method and of our Convertible Notes using the if-converted method. In periods when we recognize a net loss, we exclude the impact of outstanding stock awards, common stock warrants and the potential share settlement impact related to our Convertible Notes from the diluted loss per share calculation as their inclusion would have an antidilutive effect. For the three and nine months ended September 30, 2022, approximately 9 million of outstanding stock awards have been excluded from the calculations of diluted earnings per share attributable to common stockholders because their effect would have been antidilutive. For the three months ended September 30, 2021, approximately 5 million of outstanding stock awards were excluded. For the nine months ended September 30, 2021, approximately 18 million of outstanding stock awards and common stock warrants and approximately 4 million shares related to the potential share settlement impact related to our Convertible Notes were excluded.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We determine our provision for income taxes for interim periods using an estimate of our annual effective tax rate. We record any changes affecting the estimated annual effective tax rate in the interim period in which the change occurs, including discrete items. For the three months ended September 30, 2022, the effective tax rate was a 31.0% expense on pre-tax income, compared to an 18.7% expense on pre-tax income for the three months ended September 30, 2021. For the nine months ended September 30, 2022, the effective tax rate was an 52.6% expense on pre-tax income, compared to a 25.3% benefit on pre-tax loss for the nine months ended September 30, 2021. The change in the effective tax rate for both periods was primarily due to nondeductible mark-to-market adjustments to our minority equity investments as well as other discrete items. We are subject to taxation in the United States and foreign jurisdictions. Our income tax filings are regularly examined by federal, state and foreign tax authorities. During the fourth quarter of 2019, the Internal Revenue Service (“IRS”) issued final adjustments related to transfer pricing with our foreign subsidiaries for our 2011 to 2013 tax years. The adjustments would increase our U.S. taxable income by $696 million, which would result in federal tax of approximately $244 million, subject to interest. We do not agree with the position of the IRS. We have formally filed a protest for our 2011 to 2013 tax years and the case has been scheduled with Appeals. During the fourth quarter of 2022, the IRS issued similar proposed adjustments related

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings In the ordinary course of business, we are a party to various lawsuits. Management does not expect these lawsuits to have a material impact on the liquidity, results of operations, or financial condition of Expedia Group. We also evaluate other potential contingent matters, including value-added tax, excise tax, sales tax, transient occupancy or accommodation tax and similar matters. We do not believe that the aggregate amount of liability that could be reasonably possible with respect to these matters would have a material adverse effect on our financial results; however, litigation is inherently uncertain and the actual losses incurred in the event that our legal proceedings were to result in unfavorable outcomes could have a material adverse effect on our business and financial performance. Litigation Relating to Occupancy Taxes. One hundred three lawsuits have been filed by or against cities, counties and states involving hotel occupancy and other taxes. Eight lawsuits are currently active. These lawsuits are in various stages and we continue to defend against the claims made in them vigorously. With respect to the principal claims in these matters, we believe that the statutes or ordinances at issue do not apply to us or the services we provide and, therefore, that we do not owe the taxes that are claimed to be owed. We believe that the statutes or ordinances at issue generally impose occupancy and other taxes on entities that own, operate or control hotels (or similar businesses) or furnish or provide hotel rooms or similar accommodations. To date, forty-nine of these lawsuits have been dismissed. Some of these dismissals have been without prejudice and, generally, allow the governmental entity or entities to seek administrative remedies prior to pursuing further litigation. Thirty-four dismissals were based on a finding that we and the other defendants were not subject to the local tax ordinance or that the local government lacked standing to pursue its claims. As a result of this litigation and other attempts by certain jurisdictions to levy such taxes, we have established a reserve for the potential settlement of issues related to hotel occupancy and other taxes, consistent with applicable accounting principles and in light of all current facts and circumstances, in the amount of $44 million and $50 million as of September 30, 2022 and December 31, 2021, respectively. Our settlement reserve is based on our best estimate of probable losses and the ultimate resolution of these contingencies may be greater or less than the liabilities recorded. An estimate for a reasonably possible loss or range of loss in excess of the amount reserved cannot be made. Changes to the settlement reserve are included within legal reserves, occupancy tax and other in the consolidated statements of operations. Pay-to-Play. Certain jurisdictions may assert that we are required to pay any assessed taxes prior to being allowed to contest or litigate the applicability of the ordinances. This prepayment of contested taxes is referred to as “pay-to-play.” Payment of these amounts is not an admission that we believe we are subject to such taxes and, even when such payments are made, we continue to defend our position vigorously. If we prevail in the litigation, for which a pay-to-play payment was made, the jurisdiction collecting the payment will be required to repay such amounts and also may be required to pay interest. We are in various stages of inquiry or audit with various tax authorities, some of which, including in the City of Los Angeles regarding hotel occupancy taxes, may impose a pay-to-play requirement to challenge an adverse inquiry or audit result in court. Matters Relating to International VAT . We are in various stages of inquiry or audit in multiple European Union jurisdictions regarding the application of VAT to our European Union related transactions. While we believe we comply with applicable VAT laws, rules and regulations in the relevant jurisdictions, the tax authorities may determine that we owe additional taxes. In certain jurisdictions, including the United Kingdom, we may be required to “pay-to-play” any VAT assessment prior to contesting its validity. While we believe that we will be successful based on the merits of our positions with regard to audits in pay-to-play jurisdictions, it is nevertheless reasonably possible that we could be required to pay any assessed amounts in order to contest or litigate the applicability of any assessments and an estimate for a reasonably possible amount of any such payments cannot be made. Competition and Consumer Matters . On August 23, 2018, the Australian Competition and Consumer Commission, or "ACCC", instituted proceedings in the Australian Federal Court against trivago. The ACCC alleged breaches of Australian Consumer Law, or "ACL," relating to trivago’s advertisements in Australia concerning the hotel prices available on trivago’s Australian site, trivago’s strike-through pricing practice and other aspects of the way offers for accommodation were displayed on trivago's Australian website. On January 20, 2020, the Australian Federal Court issued a judgment finding trivago had engaged in conduct in breach of the ACL. On October 18 and 19, 2021, the court heard submissions from the parties regarding penalties and other orders. On April 22, 2022, the Australian Federal Court issued a judgment ordering trivago to pay a penalty of AU$44.7 million, which was paid in the second quarter of 2022, and to cover the ACCC’s costs arising from the proceedings.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information We have the following reportable segments: Retail, B2B, and trivago. Our Retail segment provides a full range of travel and advertising services to our worldwide customers through a variety of consumer brands including: Expedia.com and Hotels.com in the United States and localized Expedia and Hotels.com websites throughout the world, Vrbo, Orbitz, Travelocity, Wotif Group, ebookers, CheapTickets, Hotwire.com, CarRentals.com and Expedia Cruises. Our B2B segment is comprised of our Expedia Business Services organization including Expedia Partner Solutions, which offers private label and co-branded products to make travel services available to travelers through third-party company branded websites, and Egencia (until its sale in November 2021), a full-service travel management company that provides travel services to businesses and their corporate customers. Our trivago segment generates advertising revenue primarily from sending referrals to online travel companies and travel service providers from its hotel metasearch websites. We determined our operating segments based on how our chief operating decision makers manage our business, make operating decisions and evaluate operating performance. Our primary operating metric is Adjusted EBITDA. Adjusted EBITDA for our Retail and B2B segments includes allocations of certain expenses, primarily related to our global travel supply organization and the majority of costs from our product and technology platform, as well as facility costs and the realized foreign currency gains or losses related to the forward contracts hedging a component of our net merchant lodging revenue. We base the allocations primarily on transaction volumes and other usage metrics. We do not allocate certain shared expenses such as accounting, human resources, certain information technology and legal to our reportable segments. We include these expenses in Corporate and Eliminations. Our allocation methodology is periodically evaluated and may change. During the fourth quarter of 2021, we consolidated our divisional finance teams into one global finance organization, which resulted in the reclassification of expenses from Retail and B2B into our Corporate function. We have reclassified prior period segment information to conform to our current period presentation. Our segment disclosure includes intersegment revenues, which primarily consist of advertising and media services provided by our trivago segment to our Retail segment. These intersegment transactions are recorded by each segment at amounts that approximate fair value as if the transactions were between third parties, and therefore, impact segment performance. However, the revenue and corresponding expense are eliminated in consolidation. The elimination of such intersegment transactions is included within Corporate and Eliminations in the table below. Corporate and Eliminations also includes unallocated corporate functions and expenses. In addition, we record amortization of intangible assets and any related impairment, as well as stock-based compensation expense, restructuring and related reorganization charges, legal reserves, occupancy tax and other, and other items excluded from segment operating performance in Corporate and Eliminations. Such amounts are detailed in our segment reconciliation below. The following tables present our segment information for the three and nine months ended September 30, 2022 and 2021. As a significant portion of our property and equipment is not allocated to our operating segments and depreciation is not included in our segment measure, we do not report the assets by segment as it would not be meaningful.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These accompanying financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited consolidated financial statements include Expedia Group, Inc., our wholly-owned subsidiaries, and entities we control, or in which we have a variable interest and are the primary beneficiary of expected cash profits or losses. We record our investments in entities that we do not control, but over which we have the ability to exercise significant influence, using the equity method or at fair value. We have eliminated significant intercompany transactions and accounts.
Accounting Estimates	Accounting Estimates We use estimates and assumptions in the preparation of our interim unaudited consolidated financial statements in accordance with GAAP. Our estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of our interim unaudited consolidated financial statements. These estimates and assumptions also affect the reported amount of net income or loss during any period. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited consolidated financial statements include revenue recognition; recoverability of current and long-lived assets, intangible assets and goodwill; income and transactional taxes, such as potential settlements related to occupancy and excise taxes; loss contingencies; deferred loyalty rewards; stock-based compensation; accounting for derivative instruments and provisions for credit losses, customer refunds and chargebacks. The COVID-19 pandemic has created and may continue to create significant uncertainty in macroeconomic conditions, which may cause further business disruptions and adversely impact our results of operations. As a result, many of our estimates and assumptions required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods.
Reclassifications	ReclassificationsWe have reclassified prior period financial statements to conform to the current period presentation.
Seasonality	Seasonality We generally experience seasonal fluctuations in the demand for our travel services. For example, traditional leisure travel bookings are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. The number of bookings typically decreases in the fourth quarter. Since revenue for most of our travel services, including merchant and agency hotel, is recognized as the travel takes place rather than when it is booked, revenue typically lags bookings by several weeks for our hotel business and can be several months or more for our alternative accommodations business. Historically, Vrbo has seen seasonally stronger bookings in the first quarter of the year, with the relevant stays occurring during the peak summer travel months. The seasonal revenue impact is exacerbated with respect to income by the nature of our variable cost of revenue and direct sales and marketing costs, which we typically realize in closer alignment to booking volumes, and the more stable nature of our fixed costs. Furthermore, operating profits for our primary advertising business, trivago, have typically been experienced in the second half of the year, particularly the fourth quarter, as selling and marketing costs offset revenue in the first half of the year as we typically increase marketing during the busy booking period for spring, summer and winter holiday travel. As a result on a consolidated basis, revenue and income are typically the lowest in the first quarter and highest in the third quarter. The growth of our international operations, advertising business or a change in our product mix, including the growth of Vrbo, may influence the typical trend of seasonality in the future.
Recent Adopted Accounting Policies And Recent Accounting Policies Not Yet Adopted	Recent Adopted Accounting Policies In June 2022, the Financial Accounting Standards Board (“FASB”) issued new guidance related to fair value measurement of equity securities, which clarifies the fair value measurement of an equity security that is subject to a contractual sale restriction and requires specific disclosures related to such an equity security. The new guidance is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. We elected to early adopt the new guidance in the second quarter of 2022 on a prospective basis. One of our minority equity investments is accounted for in accordance with this new guidance. See Note 3 – Fair Value Measurements for additional information. Recent Accounting Policies Not Yet Adopted In October 2021, the FASB issued new guidance relate to recognizing and measuring contract assets and contract liabilities from contracts with customers acquired in a business combination. The new guidance will require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination as compared to current GAAP where an acquirer generally recognizes such items at fair value on the acquisition date. The new guidance is effective on a prospective basis for fiscal years beginning after December 15, 2022, with early adoption permitted. We do not expect it will have a material impact, if any, on our consolidated financial statements.
Revenue	RevenuePrepaid Merchant Bookings. We classify payments made to suppliers in advance of Vrbo performance obligations as prepaid merchant bookings included within prepaid and other current assets.Deferred Merchant Bookings. We classify cash payments received in advance of our performance obligations as deferred merchant bookings. Practical Expedients and Exemptions. We have used the portfolio approach to account for our loyalty points as the rewards programs share similar characteristics within each program in relation to the value provided to the traveler and their breakage patterns. Using this portfolio approach is not expected to differ materially from applying the guidance to individual contracts. However, we will continue to assess and refine, if necessary, how a portfolio within each rewards program is defined. We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
Cash, Restricted Cash and Cash Equivalents	Cash, Restricted Cash, and Cash EquivalentsOur cash and cash equivalents include cash and liquid financial instruments, including U.S. treasury securities, money market funds and term deposit investments, with maturities of three months or less when purchased. Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or our intention to use the cash for a specific purpose. Our restricted cash relates to certain traveler deposits, primarily for Vrbo, and to a lesser extent collateral for office leases.
Accounts Receivable and Allowances	Accounts Receivable and AllowancesAccounts receivable are generally due within thirty days and are recorded net of an allowance for expected uncollectible amounts. We consider accounts outstanding longer than the contractual payment terms as past due. The risk characteristics we generally review when analyzing our accounts receivable pools primarily include the type of receivable (for example, credit card vs hotel collect), collection terms and historical or expected credit loss patterns. For each pool, we make estimates of expected credit losses for our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history continually updated for new collections data, the credit quality of our customers, current economic conditions, reasonable and supportable forecasts of future economic conditions and other factors that may affect our ability to collect from customers. The provision for estimated credit losses is recorded as cost of revenue in our consolidated statements of operations.
Fair Value Measurements	We classify our cash equivalents and investments within Level 1 and Level 2 as we value our cash equivalents and investments using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Valuation of the foreign currency forward contracts is based on foreign currency exchange rates in active markets, a Level 2 input. Valuation of the cross-currency interest rate swaps is based on foreign currency exchange rates and the current interest rate curve, Level 2 inputs. We use foreign currency forward contracts to economically hedge certain merchant revenue exposures, foreign denominated liabilities related to certain of our loyalty programs and our other foreign currency-denominated operating liabilities. Our goal in managing our foreign exchange risk is to reduce, to the extent practicable, our potential exposure to the changes that exchange rates might have on our earnings, cash flows and financial position. Our foreign currency forward contracts are typically short-term and, as they do not qualify for hedge accounting treatment, we classify the changes in their fair value in other, net.
