Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Competition and Consumer Protection Reviews Online travel platforms have been the subject of investigations or inquiries by national competition authorities ("NCAs") and other authorities regarding competition law matters, consumer protection issues, and other areas. The Company is and has been involved in many such investigations and from time to time has made commitments regarding future business practices or activities, such as agreeing to narrow the scope of its contractual parity provisions with accommodation providers. Some of these investigations have resulted in fines and the Company could incur additional fines and/or be restricted in certain of its business practices in the future. In 2024, the Comisión Nacional de los Mercados y la Competencia in Spain (the "CNMC") imposed a fine and restricted certain of Booking.com's business practices such as those relating to contractual parity provisions and the ranking criteria that Booking.com can use to determine how to rank hotels in its display to customers. Booking.com does not agree with the rationale stated in the decision and the restrictions imposed, and has filed an appeal. In February 2025, the Spanish National Court ruled that the CNMC decision, including payment of the fine, is suspended pending the outcome of the appeal. The CNMC and certain third parties have sought to clarify the scope of the court's ruling, including its suspensory effect. In connection with the suspension of the fine payment, Booking.com entered into a bank guarantee arrangement in April 2025. Although the Company disagrees with the rationale stated in the CNMC decision, it recorded a liability for this matter with $485 million included in "Other long-term liabilities" and $428 million included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets as of June 30, 2025 and December 31, 2024, respectively. In 2017, the Swiss Price Surveillance Office (the "Swiss PSO") opened an investigation into the level of commissions of Booking.com in Switzerland. Booking.com received a negative decision ordering a reduction of its average commission level for hotels located in Switzerland, which Booking.com disagrees with and has appealed. The Swiss PSO order is suspended pending the outcome of the appeal, and the ordered reduction in commissions would only be effective for a three-year period after such final decision. In July 2023, the Polish Office of Competition and Consumer Protection opened an investigation into Booking.com's identification of private and professional hosts and its messaging in relation to obligations owed to consumers, and the investigation is ongoing. The French Directorate General for Competition Policy, Consumer Affairs, and Fraud Control ("DGCCRF") opened separate investigations into Booking.com and Agoda relating to certain business practices. The DGCCRF issued a final order to Booking.com to change certain of its business practices by the end of 2025 and additional discussions with the DGCCRF regarding its implementation are ongoing. Agoda received a draft decision, which it has responded to, and discussions with the DGCCRF are ongoing. In June 2025, the Hellenic Competition Commission (in Greece) opened an investigation into whether certain practices by Booking.com may produce adverse effects for hotels and other online travel agencies. If any of the investigations were to find that the Company's practices violated the respective laws, or as part of a negotiated resolution, the Company may face significant fines, restrictions on its business practices, and/or be required to make other commitments. The Company is and has been involved in investigations or inquiries by NCAs and other authorities involving consumer protection matters. The Company has previously made voluntary commitments to authorities to resolve investigations or inquiries that have included showing prices inclusive of all mandatory taxes and charges, providing information about the effect of money earned on search result rankings on or before the search results page, adjusting how discounts and statements concerning popularity or availability are shown, and displaying additional customer service details. To the extent that investigations or inquiries result in additional commitments, fines, damages, or other remedies or changes to its business, the Company's business, financial condition, and results of operations could be harmed. The Company is unable to predict how any current or future investigations or litigation may be resolved or the long-term impact of any such resolution on its business. For example, competition and consumer-law-related investigations, legislation, judgments, or issues have in the past resulted in and could in the future result in private litigation. The Company is currently involved in such litigation and/or aware of such potential litigation. Recently, for example, a European hotel association has promoted a potential class action on behalf of European hotels against Booking.com relating to the historical use of contractual parity provisions and law firms in Spain and France are promoting similar potential claims in those jurisdictions. A Dutch consumer group also signaled its intent to pursue a similar claim, as well as allegations that Booking.com and Agoda employed misleading practices, on behalf of Dutch consumers, and the Company is aware of similar efforts to pursue potential claims in other jurisdictions. German hotels have also filed parity-related claims against Booking.com and that litigation is ongoing. The Company does not agree with any such claims and intends to defend itself. However, class action litigation can be time-consuming, costly, and unpredictable, regardless of merit, and there may be evolving jurisprudence and less experience with such matters in certain of the markets where the Company is or may be involved in such litigation, making outcomes less certain and harder to forecast. If the Company were to be found liable, it could result in, among other things, payment of damages, commitments to change certain business practices, or reputational damage, any of which could harm the Company's business, results of operations, brands, or competitive position. Tax Matters Between December 2018 and August 2021, the Italian tax authorities issued assessments on Booking.com's Italian subsidiary totaling approximately $294 million for the tax years 2013 through 2018, asserting that its transfer pricing policies were inadequate. The Company believes Booking.com has been and continues to be in compliance with Italian tax law. In September 2020, the Italian tax authorities approved the opening of a mutual agreement procedure ("MAP") between Italy and the Netherlands for the 2013 tax year and the Italian tax authorities subsequently approved the inclusion of the tax years 2014 through 2018 in the MAP. As of June 30, 2025, the Company made prepayments of $87 million to the Italian tax authorities to forestall collection enforcement pending the appeal phase of the case. In April 2025, the Company was notified of a MAP resolution for the 2013 through 2018 tax years that resulted in additional Italian income taxes of $23 million and the Company formally accepted the results of the MAP in May 2025. This amount was reflected in unrecognized tax benefits as of December 31, 2024. The Company is entitled to a refund of the remaining portion of its tax prepayment. The tax resulting from the MAP is partially offset by a tax benefit of $10 million relating to Netherlands income tax. The Company is also involved in other tax-related audits, investigations, and litigation relating to income taxes, value-added taxes, travel transaction taxes (e.g., hotel occupancy taxes), withholding taxes, and other taxes. Any taxes or assessments in excess of the Company's tax provisions, including the resolution of any tax proceedings or litigation, could have a material adverse impact on the Company's results of operations, cash flows, and financial condition. In some cases, assessments may be significantly in excess of the Company's tax provisions, particularly in instances where the Company does not agree with the tax authority's assessment of how the tax laws may apply to the Company's business. Other Matters Beginning in 2014, Booking.com B.V. received several letters from the Netherlands Pension Fund for the Travel Industry (Reiswerk) ("BPF") claiming that it was required to participate in the mandatory pension scheme of the BPF with retroactive effect to 1999, which has a higher contribution rate than the pension scheme in which it is currently participating. BPF instituted legal proceedings against Booking.com B.V. and in January 2024, The Hague Court of Appeal ruled that Booking.com B.V. is required to participate in the mandatory pension scheme of the BPF with retroactive effect to 1999. Booking.com B.V. filed an appeal against that judgment and this appeal was rejected by the Dutch Supreme Court in March 2025. Booking.com B.V. will now change its pension scheme retroactively and going forward in line with the outcome of the litigation and arrangement with BPF. The Company recorded a liability for this matter with $232 million and $336 million included in "Accrued expenses and other current liabilities" in the Consolidated Balance Sheets as of June 30, 2025 and December 31, 2024, respectively. The reduction in the accrual during the six months ended June 30, 2025, reflecting the arrangement with BPF that became effective during the period, is recorded in "Personnel" expenses in the Unaudited Consolidated Statement of Operations. There may be additional claims with respect to the eligibility of certain employees in scope of the BPF. From time to time, the Company notifies the competent data protection authority, such as the Dutch data protection authority in accordance with its obligations under the General Data Protection Regulation, of certain data security incidents. Should, for example, the Dutch data protection authority decide these incidents were the result of inadequate technical and organizational security measures or practices, it may impose a fine or require other commitments. The Company has been, is currently, and expects to continue to be, subject to legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of third-party intellectual property rights. Such claims could result in the expenditure of significant financial and managerial resources, divert management's attention, and adversely affect the Company's business, reputation, results of operations, and cash flows. The Company accrues for certain other legal contingencies where it is probable that a loss has been incurred and the amount can be reasonably estimated. Such accrued amounts are not material to the Company's balance sheets and provisions recorded have not been material to the Company's results of operations or cash flows. Other Contractual Obligations and Contingencies The Company had $1.7 billion and $650 million of standby letters of credit and bank guarantees issued on behalf of the Company as of June 30, 2025 and December 31, 2024, respectively, including those issued under the revolving credit facility (see Note 9). These were obtained primarily for regulatory purposes and in connection with certain of the litigation matters disclosed above. Booking.com offers partner liability insurance that provides protection to certain accommodation partners ("home partners") in instances where a reservation has been made via Booking.com. The partner liability insurance may provide those home partners (both owners and property managers) coverage up to $1 million equivalent per occurrence, subject to limitations and exclusions, against third-party lawsuits, claims for bodily injury, or third-party personal property damage that occurred during a stay booked through Booking.com. Booking.com retains certain financial risks related to this insurance offering, which is underwritten by third-party insurance companies.
