Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements are unaudited and, in the opinion of our management, contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by such Securities and Exchange Commission rules and regulations. The preparation of our interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. We have made reasonable estimates and judgments of such items within our consolidated financial statements and there may be changes to those estimates in future periods. Our operations are seasonal and results for interim periods are not necessarily indicative of the results for the entire year. Our interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Carnival Corporation & plc 2025 joint Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on January 27, 2026 (“Form 10-K”). For 2025, we reclassified certain immaterial amounts within the Consolidated Statements of Cash Flows to conform to the current year presentation. These reclassifications did not affect net cash provided by (used in) operating, investing or financing activities. We also reclassified certain immaterial amounts in the Consolidated Statements of Income (Loss), Consolidated Statements of Comprehensive Income (Loss), Consolidated Balance Sheets, Consolidated Statements of Cash Flows and Consolidated Statements of Shareholders’ Equity to separately present amounts attributable to noncontrolling interests primarily associated with our subsidiaries that operate Isla Tropicale and Amber Cove.
Property and Equipment	Property and Equipment We review estimated useful lives and residual values of our ships for reasonableness whenever events or circumstances indicate a revision is warranted. In December 2025, we completed such review considering the period over which we expect to operate our ships and our long-term plans. As a result, we extended our ships’ depreciable lives to 35 years. In connection with the increase in estimated useful life, we reduced our estimated residual value of each ship to be 5% of our original ship cost for LNG powered ships and a range of salvage values under $25 million for all other ships, depending on the class and tonnage of the ship. This revision did not have a material impact on our consolidated financial statements and has been applied prospectively beginning December 1, 2025.
Accounting Pronouncements	Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued guidance, Income Taxes - Improvements to Income Tax Disclosures. This guidance requires disaggregation of rate reconciliation categories and income taxes paid by jurisdiction, as well as other amendments relating to income tax disclosures. This guidance is required to be adopted by us for our fiscal 2026 annual financial statements on a prospective basis with the option to apply retrospectively. We are evaluating the impact this guidance may have on our consolidated financial statements. In November 2024, the FASB issued guidance, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures - Disaggregation of Income Statement Expenses. This guidance requires annual and interim disclosure of disaggregated information for certain costs and expenses. This guidance is required to be adopted by us beginning with our fiscal 2028 annual financial statements and fiscal 2029 interim periods on a prospective or retrospective basis. We are evaluating the impact this guidance may have on our consolidated financial statements. In July 2025, the FASB issued guidance, Financial Instruments - Credit Losses - Measurement of Credit Losses for Accounts Receivable and Contract Assets. This guidance provides a practical expedient permitting an entity to assume that conditions at the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets accounted for under Revenue from Contracts with Customers. This guidance is required to be adopted by us in the first quarter of 2027 on a prospective basis. We are evaluating the impact this guidance may have on our consolidated financial statements. In September 2025, the FASB issued guidance, Intangibles - Goodwill and Other - Internal-Use Software - Targeted Improvements to the Accounting for Internal-Use Software. This guidance removes references to software development stages. Entities will be required to start capitalizing software costs when (i) management has authorized and committed to funding the software project, and (ii) it is probable the project will be completed and the software will be used as intended. This guidance is required to be adopted by us in the first quarter of 2029 on a prospective, modified, or retrospective basis. We are evaluating the impact this guidance may have on our consolidated financial statements. In May 2026, the FASB issued guidance, Environmental Credits and Environmental Credit Obligations. This guidance establishes recognition, measurement, presentation and disclosure requirements for all entities that generate, purchase, or receive environmental credits or have a regulatory compliance obligation that may be settled with environmental credits. This guidance is required to be adopted by us in the first quarter of 2029 on a retrospective basis. We are evaluating the impact this guidance may have on our consolidated financial statements.
Revenue and Expense Recognition	Guest cruise deposits and advance onboard purchases are initially included in Customer deposits when received. Customer deposits are subsequently recognized as cruise revenues, together with revenues from onboard and other activities, and all associated direct expenses of a voyage are recognized as cruise expenses, upon completion of voyages with durations of ten nights or less and on a pro rata basis for voyages in excess of ten nights. The impact of recognizing these shorter duration cruise revenues and expenses on a completed voyage basis versus on a pro rata basis is not material. Certain of our product offerings are bundled and we allocate the value of the bundled services and goods between Passenger ticket revenues and Onboard and other revenues based upon the estimated standalone selling prices of those goods and services. Future travel discount vouchers are included as a reduction of Passenger ticket revenues when such vouchers are utilized. Guest cancellation fees, when applicable, are recognized in Passenger ticket revenues at the time of cancellation. Our sales to guests of air and other transportation to and from airports near the home ports of our ships are included in Passenger ticket revenues. The related expenses of these services are included in Prepaid expenses and other when paid prior to the start of a voyage and are subsequently recognized in Commissions, transportation and other expenses at the time of revenue recognition. We had prepaid air and other transportation expenses of $210 million as of May 31, 2026 and $233 million as of November 30, 2025. The proceeds that we collect from the sales of third-party shore excursions are included in Onboard and other revenues and the related expenses are included in Onboard and other expenses. The amounts collected on behalf of our onboard concessionaires, net of the amounts remitted to them, are included in Onboard and other revenues as concession revenues. All of these amounts are recognized on a completed voyage or pro rata basis as discussed above. Fees, taxes and charges that vary with guest head counts are expensed in Commissions, transportation and other expenses when the corresponding revenues are recognized. The remaining portion of fees, taxes and charges are expensed in Other operating expenses when the corresponding revenues are recognized. Revenues and expenses from our hotel and transportation operations, which are included in our Tour and Other segment, are recognized at the time the services are performed.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured using inputs in one of the following three categories: •Level 1 measurements are based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access. Valuation of these items does not entail a significant amount of judgment. •Level 2 measurements are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or market data other than quoted prices that are observable for the assets or liabilities. •Level 3 measurements are based on unobservable data that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Considerable judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly, certain estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized in a current or future market exchange.
