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, 2021, previously filed with the SEC. The unaudited condensed consolidated balance sheet as of December 31, 2021 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. In the second quarter of 2022, as part of our continuous review of the business and in consultation with our new Chief Executive Officer ("CEO"), we evaluated our operations and realigned the reportable segment information which our chief operating decision maker ("CODM") regularly assesses to evaluate performance for operating decision-making purposes, including allocation of resources. The CODM for the Company is our CEO. The revised segment reporting structure includes the following reportable segments: (1) Tripadvisor Core; (2) Viator; and (3) TheFork. For further information on our segments, including the change in segments, and principal revenue streams within these segments refer to “Note 3: Revenue Recognition,” “Note 5: Goodwill,” and “Note 13: Segment Information,” in these notes to our unaudited condensed consolidated financial statements. All prior period segment disclosure information has been reclassified to conform to the current reporting structure in this Form 10-Q. These reclassifications had no effect on our unaudited condensed consolidated financial statements in any period. As of June 30, 2022, 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 of 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 nearly 57% of our voting power. We had no related party transactions with LTRIP during the three and six months ended June 30, 2022 and 2021, respectively.
Risks and Uncertainties	Risks and Uncertainties We continue to be subject to risks and uncertainties related to the COVID-19 pandemic. Continued widespread vaccine distributions, efficacy against existing variants (e.g., Delta, Omicron, and BA.5) and future variants, if any, of COVID-19, whether there will be resurgences of the virus and subsequent government restrictions, the extent and effectiveness of containment actions taken, and whether consumers' demand for travel and hospitality services continue to be or become negatively impacted remain uncertain. We do not know the future path or potential rate of global or regional COVID-19 resurgences, including existing COVID-19 variants (e.g., Delta, Omicron, and BA.5) and future variants, if any, nor do we have visibility into when any remaining or reinstated restrictions will be lifted, and where additional restrictions may be implemented or reinstated in the future due to resurgence of the virus. Therefore, the extent of the future impact of the COVID-19 pandemic on our business, results of operations, liquidity and financial condition remains uncertain, and is dependent on future developments that cannot be accurately predicted at this time. We continue to believe the travel, leisure, hospitality, and restaurant industries (collectively, the “travel industry”), and our financial results, would be adversely and materially affected upon a resurgence of existing COVID-19 variants (e.g., Delta, Omicron, and BA.5) or if new variants emerge which result in reinstated travel bans and/or other government restrictions and mandates, all of which negatively impact consumer demand, sentiment and discretionary spending patterns.
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. In addition, the COVID-19 pandemic has created significant uncertainty in macroeconomic conditions, which may cause further business disruptions and adversely and materially impact our results of operations. As a result, certain estimates and assumptions required increased judgment and may carry a higher degree of variability and volatility.
Seasonality	Seasonality Consumers’ travel expenditures have historically followed a seasonal pattern. Correspondingly, travel partners’ 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 hotel and rental stays, and travel activities and experiences taken, compared to the first and fourth quarters, which represent seasonal low points. During the first half of the year, experience and rentals bookings typically exceed the amount of completed experiences and rental stays, 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, which include further significant shifts in our business mix or adverse economic conditions that could result in future seasonal patterns that are different from historical trends. For example, although consumer travel demand was materially lower than historic levels due to the impact of COVID-19 on our business during 2020, these trends generally improved, albeit unevenly, during 2021, resulting in increased revenues, and working capital and operating cash flow more akin to typical historical seasonality trends, which has continued during the first half of 2022. However, it is difficult to predict the seasonality for the upcoming quarters, given the sustained uncertainty related to the continued macroeconomic impact of the COVID-19 pandemic and whether there are resurgences, or if new variants emerge, and the pace of continued recovery in our key markets.
Significant Accounting Policies	There have been no material changes to our accounting policies since December 31, 2021, as described under “Note 2: Significant Accounting Policies”, in the notes to consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2021.
