Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements present our results of operations, financial position and cash flows on a consolidated basis. The unaudited condensed consolidated financial statements include Tripadvisor, 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. All inter-company accounts and transactions have been eliminated in consolidation. One of our subsidiaries that operates in China has variable interests in affiliated entities in China in order to comply with Chinese laws and regulations, which restrict foreign investment in internet content provision businesses. Although we do not own the capital stock of these Chinese affiliates, we consolidate their results as we are the primary beneficiary of the cash losses or profits of these variable interest affiliates and have the power to direct the activity of these affiliates. Our variable interest entities’ financial results were not material for all periods presented. Investments in entities in which we do not have a controlling financial interest are accounted for under the equity method, the fair value option, as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and include all normal and recurring adjustments that management of the Company considers necessary for a fair presentation of its financial position and operating results. We prepared the unaudited condensed consolidated financial statements following the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. Additionally, certain prior period amounts have been reclassified for comparability with the current period presentation, none of which were material to the presentation of the accompanying unaudited condensed consolidated financial statements. Our interim unaudited condensed 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 condensed 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, 2023, previously filed with the SEC (the "2023 Annual Report"). The unaudited condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures including notes required by GAAP. As of March 31, 2024, Liberty Tripadvisor Holdings, Inc. (“LTRIP”) beneficially owned approximately 16.4 million shares of our common stock and 12.8 million shares of our Class B common stock, which constitute approximately 13% of the outstanding shares of common stock and 100% of the outstanding shares of Class B common stock. Assuming the conversion of all LTRIP’s shares of Class B common stock into common stock, LTRIP would beneficially own approximately 21% of the outstanding common stock. Because each share of Class B common stock is entitled to ten votes per share and each share of common stock is entitled to one vote per share, LTRIP may be deemed to beneficially own equity securities representing approximately 57% of our voting power. We had no related party transactions with LTRIP during each of the three months ended March 31, 2024 and 2023.
Risks and Uncertainties	Risks and Uncertainties Our business was negatively impacted by the risks and uncertainties related to the COVID-19 pandemic and our business would be adversely and materially affected upon a resurgence of COVID-19 or the emergence of any new pandemic or other health crisis that results in reinstated travel bans and/or other government restrictions and mandates. Following the lifting of restrictions in connection with the COVID-19 pandemic, travel demand increased. In addition, the U.S. and other countries have seen significant increased inflation and decreases in discretionary spending patterns by consumers. If macroeconomic conditions deteriorate, consumer demand and spending may decline, we may not be able to pass on increased costs to our customers and our inability or failure to navigate the macroeconomic environment could harm our business, results of operations and financial condition. Additionally, natural disasters, public health-related events, political instability, geopolitical conflicts, including the evolving events in the Middle East, acts of terrorism, fluctuations in currency values, and changes in global economic conditions are examples of other events that could have a negative impact on the travel industry, and as a result, our financial results in the future.
Accounting Estimates	Accounting Estimates We use estimates and assumptions in the preparation of our unaudited condensed 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 unaudited condensed 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 unaudited condensed consolidated financial statements is accounting for income taxes. Refer to “Note 8: Income Taxes” for information regarding our significant income tax estimates.
Seasonality	Seasonality Consumer travel expenditures have historically followed a seasonal pattern. Correspondingly, travel partner advertising investments, and therefore our revenue and operating profits, have also historically followed a seasonal pattern. Our financial performance tends to be seasonally highest in the second and third quarters of a given year, which includes the seasonal peak in consumer demand, including traveler accommodation stays, and travel experiences taken, compared to the first and fourth quarters, which represent seasonal low points. In addition, during the first half of the year, experience bookings typically exceed the amount of completed experiences, resulting in higher cash flow related to working capital, while during the second half of the year, particularly in the third quarter, this pattern reverses and cash flows from these transactions are typically negative. Other factors may also impact typical seasonal fluctuations, such as significant shifts in our business mix, adverse economic conditions, public health-related events, as well as other factors.
Significant Accounting Policies	There have been no material changes to our accounting policies since December 31, 2023, as described under “Note 2: Significant Accounting Policies”, in the notes to consolidated financial statements in Item 8 of our 2023 Annual Report.
New Accounting Pronouncements Not Yet Adopted	New Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance requiring entities to provide additional information in the income tax rate reconciliation and additional disclosures about income taxes paid. The new accounting guidance requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. This guidance is effective for annual periods beginning after December 15, 2024, and should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. In November 2023, the FASB issued new accounting guidance which expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM") and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This guidance is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted, including adoption in any interim period. We are currently considering our timing of adoption and are in the process of evaluating the impact of adopting these newly issued accounting rules on our consolidated financial statements and related disclosures.
