Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities. Unless the context otherwise indicates, references herein to the “Company” refer to the entity currently known as Bristow Group Inc. and formerly known as Era Group Inc., together with all of its current subsidiaries. Change in Fiscal Year End Effective January 1, 2023, the Company’s fiscal year end changed from March 31st to December 31st. As a result of this change, the Company filed audited financial statements for the nine-month transition period from April 1, 2022 to December 31, 2022, on a Transition Report on Form 10-KT, filed with the Securities and Exchange Commission (“SEC”) on March 9, 2023, and subsequently, filed an Annual Report on Form 10-K for the twelve months ended December 31, 2023, on March 6, 2024. The consolidated financial information for the twelve months ended December 31, 2024, twelve months ended December 31, 2023, and nine months ended December 31, 2022 has been prepared by the Company in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the SEC on this Annual Report on Form 10-K. Summary of Significant Accounting Policies Basis of Consolidation The consolidated financial statements include the accounts of Bristow Group Inc., its wholly and majority-owned subsidiaries and entities that meet the criteria of variable entities (“VIEs”) of which the Company is the primary beneficiary. All significant inter-company accounts and transactions are eliminated in consolidation. Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure on contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and those differences may be material. Reclassifications Certain amounts reported for prior periods in the consolidated financial statements have been reclassified to conform with the current period’s presentation. Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Restricted Cash The Company considers amounts deposited in escrow accounts at the end of each period as restricted cash. The Company’s restricted cash balances typically include certain payroll taxes for employee salaries in certain jurisdictions as outlined by local requirements and are shown as a separate line item in the consolidated balance sheet. Trade Receivables and Current Expected Credit Losses The Company’s customers are primarily major integrated, national and independent offshore energy companies and government agencies. The Company designates trade receivables as a single pool of assets based on their short-term nature, similar customer base and risk characteristics. Customers are typically granted credit on a short-term basis, and related credit risks are considered minimal. The Company conducts periodic quantitative and qualitative analysis on historic customer payment trends, customer credit ratings and foreseeable economic conditions. Historically, losses on trade receivables have been immaterial and uncorrelated to each other. Based on these analyses, the Company decides if additional reserve amounts are needed against the trade receivables asset pool on a case by case basis. When collection efforts have been exhausted, trade receivables and the associated allowance for doubtful accounts are removed from accounts receivable. The Company routinely reviews its trade receivables and makes provisions for expected credit losses; however, such provisions are estimates and actual results could differ from those estimates and those differences may be material. The provision for credit losses for the periods reflected below were as follows (in thousands): December 31, 2024 2023 Balance – beginning of period $ 77 $ 1,847 Additional allowances 141 — Write-offs and collections (165) (1,774) Foreign currency effects (11) 4 Balance – end of period $ 42 $ 77 Inventories Inventories consist primarily of spare parts utilized for maintaining the Company’s global fleet of aircraft and are stated at average cost, net of allowances for excess and obsolete inventory. The Company establishes an allowance to accrue for the retirement of the cost of spare parts expected to be on hand at the end of a fleet’s life over the service lives of the related equipment, taking into account the estimated salvage value of the parts. As of December 31, 2024 and 2023, the inventory allowances for the periods reflected below were as follows (in thousands): December 31, 2024 2023 Balance – beginning of period $ 2,955 $ 2,536 Additional allowances 725 386 Foreign currency effects (237) 33 Balance – end of period $ 3,443 $ 2,955 Property and equipment Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful life of the asset to an estimated salvage value. With respect to helicopters, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life. The Company reviews the estimated useful lives and salvage values of its property and equipment on an ongoing basis for any changes in estimates. As of December 31, 2024, the estimated useful life (in years) of the Company’s categories of new property and equipment was as follows: Aircraft (estimated salvage value at 10%-25% of cost) 30 Aircraft accessories and spares 5 - 7 Buildings (estimated salvage value at 10% of cost) 30 Leasehold improvements lesser of lease term or 10 Other property and equipment 3-15 The Company performs an impairment analysis on long-lived assets used in operations when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. The Company’s long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If an impairment is indicated for the asset group classified as held and used, an impairment evaluation will be performed. Asset impairment evaluations are based on estimated undiscounted cash flows over the remaining useful life for the assets being evaluated. If the sum of the expected future cash flows is less than the carrying amount of the asset group, the Company would be required to recognize an impairment loss. For aircraft types that are still operating where management has made the decision to sell or abandon the aircraft type at a fixed date, an analysis is completed to determine whether depreciation needs to be accelerated or additional depreciation recorded for an expected reduction in residual value at the planned disposal date. Investment in Unconsolidated Affiliates The Company uses a measurement alternative approach for equity investments without readily determinable fair values. The alternative method measures equity investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions in a similar investment of the same issuer. The Company performs regular reviews of each unconsolidated affiliate investee’s financial condition, the business outlook for its products and services and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties raising capital to continue operations, the investment is written down to fair value. Leases The Company recognizes a right-of-use (“ROU”) asset and a lease liability on its consolidated balance sheets for leases under which it is the lessee, after applying the short-term lease exemption. Operating lease ROU assets and liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. For the applied discount rate, the Company uses its incremental borrowing rate based on information available at commencement date if the rate implicit in the lease cannot be readily determined. Contract Fulfillment Costs Costs to fulfill a contract with a customer incurred in advance of the commencement of a new contract are recognized as an asset and amortized on a straight-line basis over the life of the contract if the costs are directly related to the new contract, the costs are specifically identifiable, the costs generate or enhance resources of the entity and are expected to be recovered by the Company. These deferred costs are included in other long-term assets with the amount due for amortization within a year reflected in prepaid expenses and other current assets on the consolidated balance sheets. The balance is amortized through operating expense on the consolidated statements of operations. As of December 31, 2024 and 2023, deferred costs were $34.2 million and $17.4 million, respectively. During the twelve months ended December 31, 2024 and 2023, the Company recognized $3.6 million and $2.5 million, respectively, of amortization related to these deferred costs. Intangible Assets Intangible assets with finite useful lives are amortized over their estimated useful lives. Finite lived intangible assets are reviewed for impairment when indicators of impairment are present. Indicators of impairment for finite lived intangible assets are the same as those for impairment of long-lived assets. For finite lived intangible assets, an impairment loss is recognized if the carrying amount of the asset exceeds the undiscounted cash flows projected to be generated by the asset. If the finite lived intangible asset is impaired, then the amount of the impairment is calculated as the excess of the asset’s carrying amount over its fair value. After an impairment loss is recognized, the adjusted carrying amount of the intangible asset will be its new accounting basis and the useful life of that asset will be reevaluated. Contingencies The Company establishes reserves for estimated loss contingencies when it believes a loss is probable and the amount of the loss can be reasonably estimated. The Company’s contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities and are adjusted as a result of changes in facts or circumstances that become known or changes in previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information that becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current year. Should the outcome differ from the Company’s assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized. Legal costs related to contingent liabilities are expensed as incurred. Deferred Financing Costs Deferred financing costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method. Pension Benefits See Note 14 for a discussion of the Company’s accounting for pension benefits. Derivative Financial Instruments The Company records changes in fair value of derivatives designated as cash flow hedges in accumulated other comprehensive income (loss) in its consolidated balance sheets until the forecasted transaction occurs. When the forecasted transaction affects earnings, the Company reclassifies the related gain or loss on the cash flow hedges to earnings. The Company evaluates hedge effectiveness at the inception of the hedge prospectively, and on an ongoing basis both retrospectively and prospectively. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, it will reclassify the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) to earnings. Revenue Recognition Revenues are recognized over time as the contracted aviation services are performed for a customer, when the transaction price is determined, and collection has occurred or is probable of occurring. A majority of the Company’s revenues are generated through two types of contracts: helicopter services and fixed wing services. The Company typically invoices customers on a monthly basis, and the term between invoicing and when the payment is due is typically between 30 and 60 days for helicopter services and fixed wing charter customers. Payment is made at the point of sale for fixed wing regular passenger transport customers. Deferred revenues are primarily generated by fixed wing services where customers pay for tickets in advance of receiving the Company’s services and from advanced payments from helicopter services customers. Helicopter services — Revenues from helicopter services are recognized over time based on contractual rates as the helicopter services are performed. Revenues are primarily derived from fixed-term contracts which typically have original terms of one Fixed wing services — The Company provides fixed wing transportation services through regular passenger transport (scheduled airline service with individual ticket sales) and charter services. Revenues are recognized as service is provided or in the period in which the right to travel expires, which is determined by the terms and conditions of the ticket. Both chartered and scheduled airline service revenues are recognized net of passenger taxes and discounts. Maintenance and Repairs The Company generally charges maintenance and repair costs, including major helicopter component overhaul costs, to earnings as the costs are incurred. However, certain helicopter components, such as engines and transmissions, are maintained by third-party vendors under contractual agreements also referred to as power-by-the-hour (“PBH”) maintenance agreements. Under these agreements, the Company is charged an agreed amount per hour of flying time related to maintenance, repair and overhaul of the parts and components covered. The costs charged under these contractual agreements are recognized in the period in which the flight hours occur. To the extent that the Company has not yet been billed for costs incurred under these arrangements, these costs are included in accrued maintenance and repairs on its consolidated balance sheets. In the event the Company places a helicopter in a PBH program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown since the previous maintenance event. This buy-in charge is normally recorded as a prepaid expense and amortized as an operating expense over the remaining PBH contract period. From time to time, the Company receives credits from its original equipment manufacturers. The Company records these credits as a reduction in maintenance expense when the credits are utilized in lieu of cash payments for purchases or services, unless the credit represents a sales incentive offered to customers by the manufacturer. The cost of certain major overhauls on owned fixed-wing aircraft are capitalized when incurred and depreciated over the period until the next expected major overhaul. The cost of major overhauls on leased fixed-wing aircraft are charged to operating expense when incurred. Share-Based Compensation The grant date fair value of share-based awards granted to employees is recognized as an employee compensation expense over the requisite service period on a straight-line basis. The amount of compensation expense ultimately recognized is based on the number of awards that meet the vesting conditions at the vesting date. Foreign Currency Transactions The reporting currency for all of the Company’s foreign entities is the U.S. dollar. From time to time, the Company enters into transactions denominated in currencies other than its reporting currency. Gains and losses resulting from changes in currency exchange rates between the reporting currency and the currency in which a transaction is denominated are included in other, net in the Company’s consolidated statements of operations in the period which the currency exchange rates change. During the twelve months ended December 31, 2024 and 2023, the Company recognized foreign currency exchange losses of $8.9 million and of $10.7 million, respectively. During the nine months ended December 31, 2022, the Company recognized foreign currency exchange gains of $14.9 million. The functional currency for some subsidiaries outside the United States is the local currency. Financial statements of these subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities, with translation adjustments for non-monetary assets and liabilities reflected in equity. Under U.S. GAAP, an economy is considered highly inflationary if the cumulative inflation rate for a three-year period meets or exceeds 100 percent. If a foreign entity is considered to be in a highly inflationary economy, the financial statements of that entity are remeasured as though the functional currency were the reporting currency. The three-year inflation rate for Nigeria exceeded the three-year cumulative inflation rate of 100 percent as of September 30, 2024. Therefore, effective October 1, 2024, the Company began accounting for its Nigerian entity as a foreign entity operating in a country with a highly inflationary economy. Upon making the change in functional currency, the translated amounts for non-monetary assets and liabilities as of September 30, 2024 became the accounting basis for those balances. Translation adjustments for periods prior to October 1, 2024 will remain in equity. Going forward, monetary assets and liabilities denominated in the Nigerian naira are remeasured into U.S. dollars each reporting period, with remeasurement gains and losses recognized in other, net in the Company’s consolidated statements of operations. After applying highly inflationary accounting effective October 1, 2024, the Company recognized a loss on foreign exchange of $1.6 million in 2024. Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based upon temporary differences between the carrying amount and tax basis of the Company’s assets and liabilities and measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred income tax assets and liabilities of a change in the tax rates is recognized in income in the period in which the change occurs. The Company records a valuation allowance when it believes that it is more-likely-than-not that any deferred income tax asset created will not be realized. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not listed below were assessed and determined as not applicable to the Company’s consolidated financial position or result of operations. In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), requiring a footnote disclosure about specific expenses by requiring public business entities to disaggregate, in a tabular presentation, each relevant expense caption on the face of the income statement that includes purchases of inventory, employee compensation, depreciation and intangible asset amortization. The tabular disclosure would also include certain other expenses, when applicable. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027 (as amended in the FASB update in January 2025 in ASU 2025-01). The Company is evaluating the potential impact of the adoption of this ASU on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The purpose of ASU 2023-09 is to enhance the transparency and decision usefulness of income tax disclosures to investors and other allocators of capital. The objectives of the amendment is to provide information to better assess how an entity’s operations and related tax risk and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This standard will be effective prospectively for fiscal years beginning after December 15, 2024. The Company has evaluated the impact of adopting this ASU on its consolidated financial statements and determined adoption will not have a material impact and additional rate reconciliation disclosures will be included, beginning with its 2025 Annual Report on Form 10-K. In November 2023, the FASB issued ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU applies to all public entities that are required to report segment information in accordance with Topic 280 and requires the disclosure of significant segment expenses on an annual and interim basis, incremental disclosures of measures of segment profit or loss and the identification of the Company’s chief operating decision maker. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this ASU beginning with this Annual Report on Form 10-K. See Note 17 — Segments in this Annual Report on Form 10-K for the added disclosures.

Other Asset and Inventory Considerations During the nine months ended December 31, 2022, the Company entered into and amended two existing PBH agreements with maintenance service providers for its AW139 helicopter fleet. The terms of these agreements included a buy-in payable of approximately $55.0 million for the hours flown on the aircraft prior to entry into the PBH agreements. The buy-in amount for the transaction has been paid in full and is reflected in other long-term assets with the amount due for amortization within a year reflected in prepaid expenses and other current assets on the consolidated balance sheets. The balance is amortized through operating expense on the consolidated statements of operations on a straight-line basis over the contract term. During the nine months ended December 31, 2022, the Company wrote off $5.2 million of intangible assets related to legacy AW139 airframe agreements in connection with these PBH agreements. This resulted in a loss reported under the loss on impairment line

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES	VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES. A variable interest entity (“VIE”) is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. A VIE is consolidated by its primary beneficiary. The primary beneficiary has both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. If the Company determines that it has operating power and the obligation to absorb losses or receive benefits, it will consolidate the VIE as the primary beneficiary. If not, the Company will not consolidate the VIE. As of December 31, 2024, the Company had interests in seven VIEs of which the Company was the primary beneficiary. The Company determined it was the primary beneficiary based on the VIE model under ASC 810, as it has the power to direct the most significant activities impacting the economic performance of each of the seven VIEs. For example, Bristow has the ability to determine how capital is deployed through the provision of assets and loan agreements that provide funding, the timing and terms of payments and other transactions between these entities and Bristow as well as financial operating decisions, asset maintenance cycles, and decisions on leases for each VIE. Additionally, through its equity ownership of each of the VIEs, the Company has the obligation to absorb the losses of each VIE and the right to receive residual returns for each of the VIEs, in each case that could potentially be significant to the applicable VIE. The Company had no interests in VIEs of which the Company was not the primary beneficiary. BNAS Holdings Company Limited (“BNAS”) — BNAS is a legal entity in the Republic of Ireland owned by Bristow Helicopters Limited (“BHL”) as a 49% shareholder and 51% by a European Union national. BHL provided a loan to BNAS, which in turn acquired 100% of the share capital of Bristow Norway A/S, a company that provides aviation services to the offshore energy industry in Norway. The financial information for this VIE is aggregated within the summary financial information table below. Bristow Aviation Holdings Limited (“Bristow Aviation”) — The Company owns common stock and a significant amount of Bristow Aviation’s subordinated debt. Bristow Aviation is incorporated in England and, through its subsidiaries, holds all the outstanding shares in BHL. As of December 31, 2024, the Company and Impigra (as defined below) owned 49% and 51%, respectively, of Bristow Aviation. A number of the subsidiaries of Bristow Aviation provide aviation services to customers primarily in Australia, Nigeria, Norway, Trinidad and the UK. Bristow Aviation’s subsidiaries include BNAS, BHNL, PAAN and YII Energy (as defined below), and it eliminates all transactions among and between these VIEs. Bristow EU Holdco B.V. (“BEU”) — BEU is a legal entity in the Netherlands to provide services in certain European Union jurisdictions. BEU is 49% owned by the Company and 51% owned by a European Union national. Bristow Helicopters (Nigeria) Limited (“BHNL”) — BHNL is a joint venture that provides aviation services to customers in Nigeria, in which BHL owns a 48% interest. YII Energy (as defined below), a Nigerian company owned 100% by Nigerian citizens, owns a 50% interest and an employee trust fund owns the remaining 2% interest. Impigra Aviation Holdings Limited (“Impigra”) — Impigra is a British company owned 100% by UK Bristow employees and owns 51% of the ordinary shares of Bristow Aviation. The assets and liabilities of Impigra consist primarily of intercompany balances, including loans, which are eliminated in consolidation. Pan African Airlines (Nigeria) Limited (“PAAN”) — PAAN is a joint venture in Nigeria with local partners in which the Company owns an interest of 56.15%. PAAN provides industrial aviation services to customers in Nigeria. YII 5668 Energy (“YII Energy”) — YII Energy is a dormant entity domiciled in Nigeria and owns a 50% interest in BHNL. The Company eliminates all transactions among and between the VIEs listed above within its consolidated financial statements. For each of the seven VIEs, the VIE’s assets can be used for purposes other than the settlement of the VIE’s obligations and creditors of the VIEs have recourse against the general credit of the Company. Additionally, these VIEs are primarily holding companies with assets that are principally investments in other entities within the group. The Company aggregates these VIEs because no entity is individually significant to the Company, and the risks and rewards of each VIE are substantially similar to one another and to Bristow’s operations elsewhere. For example, these entities primarily exist in support of aviation services either to a broad base of offshore energy companies, to government agencies, or to both. Furthermore, they are subject to the same commodity price risks, and to a large extent, are tied to the level of offshore exploration, development and production activity by energy companies or government spending habits; aircraft availability and supply chain dynamics; and the pricing, terms and conditions of contracts are similar in nature. The following table shows summarized financial information, in aggregate, for the Company’s VIEs and their subsidiaries (in thousands): December 31, 2024 2023 Total assets $ 1,362,223 $ 1,076,745 Total liabilities (1) $ 5,730,561 $ 5,274,946 ____________________ (1) Includes Bristow Aviation subordinated unsecured loan stock (debt) bearing interest at an annual rate of 13.5% and payable semi-annually to the Company that is not eliminated at the Bristow Aviation and subsidiaries summarized financial information level, but is eliminated at Bristow Group Inc. and subsidiaries. Payment of interest on such debt has been deferred since its incurrence in 1996 at an annual rate of 13.5% and aggregated $4.6 billion and $4.2 billion as of December 31, 2024 and 2023, respectively. Other Significant Affiliates — Unconsolidated The Company evaluates its unconsolidated affiliates for indicators of impairment in light of current market conditions. Changes in market conditions or contractual relationships in future periods could result in the identification of additional other-than-temporary impairment. Cougar — The Company owns a 25% voting interest and a 40% economic interest in Cougar Helicopters Inc. (“Cougar”), an aviation services provider in Canada. Cougar’s operations are primarily focused on serving the offshore energy industry off Canada’s Atlantic coast and in the Arctic. Cougar is accounted for as an equity method investment. The Company records its share of Cougar’s financial results in earnings from unconsolidated affiliates on the consolidated statement of operations. Additionally, the Company recognizes revenues related to aircraft and facilities that it leases to Cougar and revenues associated with a Maintenance Services and Support Agreement (the “MSSA”). As of December 31, 2024 and 2023, the investment in Cougar totaled $5.2 million and $2.9 million and is included on the consolidated balance sheets in investment in unconsolidated affiliates. During the twelve months ended December 31, 2024 and 2023, and the nine months ended December 31, 2022, the Company recognized $3.7 million, $6.8 million and $1.5 million, respectively, related to its share of Cougar’s financial results. PAS — The Company has a 25% economic interest in Petroleum Air Services (“PAS”), an Egyptian corporation that provides helicopter and fixed wing transportation to the offshore energy industry and other general aviation services in Egypt. PAS is accounted for as a cost method investment. As of December 31, 2024 and 2023, the investment in PAS totaled $17.0 million and is included on the consolidated balance sheets in investment in unconsolidated affiliates. During the twelve months ended December 31, 2024 and 2023, dividends received were $0.4 million and $0.3 million, respectively. There were no dividends received during the nine months ended December 31, 2022.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Authoritative guidance on fair value measurements provides a framework for measuring fair value and establishes a fair value hierarchy that prioritizes the inputs used to measure fair value, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs). The fair values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate their carrying values due to the short-term nature of these items. The Company’s debt was measured at fair value using Level 2 inputs based on estimated current rates for similar types of arrangements using discounted cash flow analysis. Considerable judgment was required in developing certain of the estimates of fair value, and, accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a current market exchange. The carrying and fair values of the Company’s debt were as follows (in thousands): Carrying Level 1 Level 2 Level 3 December 31, 2024 LIABILITIES 6.875% Senior Notes (1) $ 395,610 $ — $ 397,872 $ — UKSAR Debt (2) 200,273 — 205,545 — IRCG Debt (3) 93,900 — 95,912 — $ 689,783 $ — $ 699,329 $ — December 31, 2023 LIABILITIES 6.875% Senior Notes (1) $ 394,184 $ — $ 383,068 $ — UKSAR Debt (2) 153,886 — 162,467 — $ 548,070 $ — $ 545,535 $ — _________________ (1) As of December 31, 2024 and 2023, the carrying values of unamortized deferred financing fees related to the 6.875% Senior Notes were $4.4 million and $5.8 million, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS From time to time, the Company may use derivatives to partially offset its business exposure to foreign currency risks on expected future cash flows. The Company enters into master netting arrangements to mitigate credit risk in derivative transactions by permitting net settlement of transactions with the same counterparty. The Company does not offset fair value amounts recognized for derivative instruments under master netting arrangements. The derivative agreements do not contain credit-risk-related contingent features. There are no amounts of related financial collateral received or pledged. The Company does not use any of its derivative instruments for speculative or trading purposes. Cash Flow Hedges The Company may use foreign exchange options or forward contracts to hedge a portion of its forecasted foreign currency denominated transactions. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on hedged transactions. These foreign exchange hedge contracts, carried at fair value, have maturities of up to 12 months. As of December 31, 2024 and 2023, total notional amounts of outstanding cash flow hedges were $82.2 million and $254.7 million, respectively. As of December 31, 2024, the estimated net amounts of losses expected to be reclassified from accumulated other comprehensive income into earnings within the next 12 months is $0.5 million. For the twelve months ended December 31, 2024, twelve months ended December 31, 2023 and nine months ended December 31, 2022, there were no net gains or losses recognized in earnings relating to hedges of forecasted transactions that did not occur. The Company’s derivative assets and liabilities measured at fair value are classified as Level 2 within the fair value hierarchy. The fair value of the Company’s derivatives is based on valuation methods which project future cash flows and discount the future amounts to present value using market-based observable inputs, including interest rate curves and foreign currency rates. The fair value of derivative instruments on our Consolidated Balance Sheets as of December 31, 2024 and 2023 were as follows, presented on a gross basis (in thousands): December 31, 2024 2023 Fair Value Asset Derivatives Fair Value Liability Derivatives Fair Value Asset Derivatives Fair Value Liability Derivatives Derivatives designated as hedging instruments: Foreign exchange forward contracts $ 1,351 $ 1,871 $ 2,557 $ 1,200

Included in these commitments are orders to purchase eight AW189 heavy helicopters, two AW139 medium helicopters, five AW169 light twin helicopters and two H135 light twin helicopters. The AW189 helicopters are scheduled to be delivered between 2025 and 2026; and the AW139 helicopters and the H135 helicopters are scheduled to be delivered in 2025. Delivery dates for the AW169 helicopters have yet to be determined. In addition, the Company has outstanding options to purchase up to ten additional AW189 helicopters and ten additional H135 helicopters. If these options are exercised, the AW189 helicopters would be scheduled for delivery between 2026 and 2028, and the H135 helicopters would be scheduled for delivery between 2027 and 2028. The Company may, from time to time, purchase aircraft for which it has no orders. The Company may terminate $32.6 million of its capital commitments without further liability other than aggregate liquidated damages of approximately $1.0 million. General Litigation and Disputes The Company operates in jurisdictions internationally where it is subject to risks that include government action to obtain additional tax revenues. In a number of these jurisdictions, political unrest, the lack of well-developed legal systems and legislation that is not clear enough in its wording to determine the ultimate application, can make it difficult to determine whether legislation may impact the Company’s earnings until such time as a clear court or other ruling exists. The Company operates in jurisdictions currently where amounts may be due to governmental bodies that the Company is not currently recording liabilities for as it is unclear how broad or narrow legislation may ultimately be interpreted. The Company believes that payment of amounts in these instances is not probable at this time, but is reasonably possible. In the normal course of business, the Company is involved in various litigation matters including, among other things, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its consolidated financial statements related thereto as appropriate. It is possible that a change in its estimates related to these exposures could occur, but the Company does not expect such changes in estimated costs or uninsured losses, if any, would have a material effect on its business, consolidated financial position or results of operations.

INCOME TAXES	INCOME TAXES The Company recognizes deferred tax assets or liabilities for the differences between the financial statement carrying amount and tax basis of assets and liabilities using enacted tax rates in effect for the years in which the asset is expected to be recovered or the liability is expected to be settled. The components of deferred tax assets and liabilities are as follows (in thousands): December 31, 2024 2023 Deferred tax assets: Foreign tax credits $ 6,275 $ 19,456 Net operating losses 137,902 153,068 Pension liability 41 (269) Interest expense limitation 53,572 49,431 Accrued expenses not currently deductible 12,682 18,367 Lease liabilities 87,778 34,553 Other 7,660 6,544 Gross deferred tax assets 305,910 281,150 Valuation allowance (139,272) (155,411) Total deferred tax assets $ 166,638 $ 125,739 Deferred tax liabilities: Property and equipment $ (92,505) $ (99,684) Inventories (976) (1,366) Investment in foreign subsidiaries and unconsolidated affiliates (2,764) (6,365) Right-of-use lease asset (87,826) (34,496) Intangibles (13,838) (13,245) Other 17,692 (2,578) Total deferred tax liabilities $ (180,217) $ (157,734) Net deferred tax liabilities $ (13,579) $ (31,995) As of December 31, 2024, the Company had deferred tax assets of $25.4 million recorded in other assets on the consolidated balance sheets. For U.S. income taxes, companies may use foreign tax credits to offset the income taxes due on income earned from foreign sources. The foreign tax credits claimed for a particular taxable year may be limited. Foreign tax credits may be carried back one year and forward ten years. As of December 31, 2024, the Company had $19.5 million of excess foreign tax credits, of which, $13.2 million expired in 2024 and $6.3 million will expire after 2025. As of December 31, 2024, the Company had a $21.8 million net operating loss carryforward in the U.S. In addition, the Company has net operating losses in certain states totaling $563.5 million, which began to expire during the twelve months ended December 31, 2024. The following table shows the expiration of such loss carryforwards (in thousands, except dates): December 31, 2024 Expiration Foreign tax credit carryforwards $6,275 2025-2033 Foreign net operating loss carryforwards $373,558 Indefinite State net operating loss carryforwards $428,533 Indefinite State net operating loss carryforwards $134,934 2025-2042 Section 163j interest expense $255,092 Indefinite The Company estimates the likelihood of the recoverability of its deferred tax assets. Any valuation allowance recorded is based on estimates and assumptions of taxable income in future periods and a determination is made of the magnitude of deferred tax assets which are more likely than not to be realized. If these estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets and its effective tax rate may increase which could result in a material adverse impact on the Company’s financial position and results of operations. The valuation allowance continues to be applied against certain deferred income tax assets where the Company has assessed that the realization of such assets does not meet the “more likely than not” criteria. Valuation allowances against net deferred tax assets aggregated to $139.3 million and $155.4 million as of December 31, 2024 and 2023, respectively. As of December 31, 2024, valuation allowances were $62.3 million for foreign operating loss carryforwards, $18.6 million for other temporary differences, $26.1 million for state operating loss carryforwards, $28.2 million for interest expense limitation carryforwards, $3.2 million for foreign tax credits and $1.0 million for capital loss carryforwards. As of December 31, 2023, valuation allowances were $79.1 million for foreign operating loss carryforwards, $32.4 million for state operating loss carryforwards, $27.7 million for interest expense limitation carryforwards and $15.3 million for foreign tax credits and $0.9 million for capital loss carryforwards. The Company recorded $3.1 million of deferred taxes related to the change in estimated UK pension liabilities. This amount is reflected in other comprehensive income. During the twelve months ended December 31, 2024, the Company utilized $27.6 million of net operating losses in various foreign jurisdictions and released through continuing operations an offsetting valuation allowance previously recorded against the net operating losses. The components of income (loss) before income taxes for the periods reflected in the table below were as follows (in thousands): Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Domestic $ 21,188 $ (39,130) $ (7,692) Foreign 80,875 57,142 28,771 Income (loss) before income taxes $ 102,063 $ 18,012 $ 21,079 The components of income tax expense (benefit) for the periods reflected in the table below were as follows (in thousands): Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Current: Domestic $ 12,839 $ 10,347 $ 3,995 Foreign 14,314 13,916 8,821 $ 27,153 $ 24,263 $ 12,816 Deferred: Domestic $ (14,519) $ (2,568) $ (3,419) Foreign (5,441) 3,237 (1,903) $ (19,960) $ 669 $ (5,322) Income tax expense $ 7,193 $ 24,932 $ 7,494 The reconciliation of the U.S. Federal statutory tax rate to the effective income tax rate for the periods reflected in the table below is as follows: Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Statutory rate 21.0 % 21.0 % 21.0 % Net foreign tax on non-U.S. earnings 0.9 % 15.5 % 49.0 % Foreign earnings double tax relief (8.0) % (9.5) % (5.0) % Foreign earnings indefinitely reinvested abroad — % (3.4) % (28.7) % Change in valuation allowance (3.5) % (23.6) % (12.9) % Foreign earnings that are currently taxed in the U.S. — % 7.4 % 5.9 % Changes in prior year estimates (0.3) % — % 0.9 % Impact of U.S. withholding tax 10.6 % 2.2 % 3.6 % Impact of tax rate changes 2.9 % 2.6 % — % Foreign tax credits 12.9 % 76.5 % — % Deferred gains (3.1) % 7.9 % — % GILTI income 0.9 % 19.8 % — % Other, net (27.2) % 22.0 % 1.8 % Effective tax rate 7.1 % 138.4 % 35.6 % The Company is domiciled in the U.S. and is a U.S. tax resident. It’s subsidiaries conduct operations and earn income in numerous countries and are subject to the laws of taxing jurisdictions within those countries. The Company’s effective income tax rate for the twelve months ended December 31, 2024 is primarily impacted by income tax from non-US earnings in certain profitable jurisdictions with differences in tax rates in such taxing jurisdictions, adjustments to valuation allowances against future realization of deductible business interest expense and adjustments to valuation allowances against net operating losses. Double tax relief is a mechanism designed to prevent companies from being taxed twice on the same income in difference jurisdictions. This relief applies to corporate entities that earn income both jurisdictions. Due to increased profitability, the Company was able to claim double tax relief where previously these amounts were written off or claimed as foreign tax expense, resulting in an incremental decrease to the effective tax rate of 8.0% for the twelve months ended December 31, 2024. During the twelve months ended December 31, 2024, the consolidated effective income tax rate includes $13.2 million of expired foreign tax credits in the United States due to the 10-year carryforward limitation. However, there was a corresponding valuation allowance released which fully offset the impact of the effective income tax rate in the change in valuation allowances. The Company continues to evaluate tax planning strategies to maximize the utilization of available foreign tax credits and minimize expiration risks. The Company’s 2024 consolidated effective income tax rate includes other, net discrete tax benefits of 18.4% from currency translation adjustments, a release of an unrecognized tax benefit of 4.0% due to the expiration of the statute of limitation on uncertain tax positions in foreign jurisdictions and a 7.8% tax benefit associated with adjustments to deferred tax balances. The Company’s 2023 consolidated effective income tax rate includes $15.6 million of expired foreign tax credits in the United States due to the 10-year carryforward limitation. However, there was a corresponding valuation allowance released, which fully offset the impact of the effective income tax rate in the change in valuation allowances. The Company continues to evaluate tax planning strategies to maximize the utilization of available foreign tax credits and minimize expiration risks. The Company’s 2023 consolidated effective income tax rate includes other, net tax expense of 5.8% from imputed interest, UK disallowed interest of 8.6% and non-deductible expenses of 5.3%. The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company is currently undergoing multiple tax examinations in various jurisdictions in which it operates. The ultimate settlement and timing of these additional potential tax assessments is uncertain, but the Company will continue to vigorously defend its return filing positions and does not view additional assessments as probable at this time. The following table summarizes the years open by jurisdiction as of December 31, 2024: Years Open U.S. 2021 to present UK 2023 to present Nigeria 2014 to present Guyana 2015 to present Trinidad 2018 to present Australia 2020 to present Norway 2019 to present Brazil 2020 to present During the twelve months ended December 31, 2024, adjustments were made to estimates for uncertain tax positions in certain tax jurisdictions based upon changes in facts and circumstances, resulting in a decrease to income tax expense. As of December 31, 2024 and 2023, the Company had $0.1 million and $4.2 million, of unrecognized tax benefits respectively, all of which would have an impact on its effective tax rate, if recognized. During the twelve months ended December 31, 2024, the Company released $4.1 million of unrecognized tax benefits due to the expiration of the statue of limitations on uncertain tax positions in foreign jurisdictions. The activity associated with unrecognized tax benefit for the periods reflected in the table below was follows (in thousands): Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Unrecognized tax benefits – beginning of period $ 4,173 $ 4,067 $ 3,942 Increases for tax positions taken in prior periods — 106 200 Decreases for tax positions taken in prior periods — — (75) Decrease related to statute of limitation expirations (4,073) — — Unrecognized tax benefits – end of period $ 100 $ 4,173 $ 4,067 As of December 31, 2024, the Company had aggregated approximately $351.4 million in unremitted earnings generated by foreign subsidiaries. The Company expects to indefinitely reinvest these earnings. The Company has not provided deferred taxes on these unremitted earnings. If the Company’s expectations were to change, withholding and other applicable taxes incurred upon repatriation, if any, are not expected to have a material impact on its results of operations.

Share-Based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION In August 2021, the Company adopted the 2021 Equity Incentive Plan (the “LTIP”). The LTIP allows for awards to be granted in the form of stock options, stock appreciation rights, shares of restricted stock, other share-based awards (payable in cash or common stock) or performance awards, or any combination thereof, and may be made to outside directors, employees or consultants. As of December 31, 2024, 962,279 shares remained available to grant under the LTIP. Restricted Stock — During the twelve months ended December 31, 2024, the number of shares and the weighted average grant price of restricted stock transactions were as follows: Number of Shares Weighted Average Grant Price Non-vested as of January 1, 2024: 1,443,675 $ 29.36 Granted 614,785 $ 26.93 Vested/released (408,148) $ 26.89 Cancelled/forfeited (96,323) $ 28.17 Non-vested outstanding as of December 31, 2024 1,553,989 $ 29.12 The weighted average grant date fair value of restricted stock granted was $24.35 and $29.33 during twelve months ended December 31, 2023 and nine months ended December 31, 2022, respectively. The aggregate intrinsic value of the awards that vested and were released during the twelve months ended December 31, 2024, twelve months ended December 31, 2023 and nine months ended December 31, 2022 was $13.1 million, $11.2 million and $5.7 million, respectively. As of December 31, 2024, the Company had approximately $18.6 million in total unrecognized compensation costs associated with these awards, and the weighted average period over which it is expected to be recognized is 1.7 years. The Company grants non-performance based restricted stock units and Cash Return on Invested Capital (“ROIC”) awards. For both types of awards fair values are derived at grant date using the Company’s closing stock price on the day the awards are granted and they vest over a three year period. The grant date fair values on performance-based restricted stock units (“PSUs”) and Total Stock Return (“TSR”) awards are determined under a Monte Carlo Simulation in a risk-neutral framework using Geometric Brownian Motion and will vest on a cliff-basis, after three years, subject to certain stock price performance targets. Stock Options — During the twelve months ended December 31, 2024, the number of stock options transactions and the weighted average grant price of stock options were as follows: Number of Shares Weighted Average Grant Price Weighted Average Exercise Price Outstanding as of January 1, 2024: 376,079 $ 19.83 $ 20.34 Exercised/released (36,542) $ 17.48 $ 20.53 Expired (1,859) $ 30.16 $ 29.84 Outstanding as of December 31, 2024 337,678 $ 20.03 $ 20.27 Vested and exercisable 337,678 $ 20.03 $ 20.27 As of December 31, 2024, the Company had no unrecognized compensation costs associated with stock options. The weighted average remaining contractual term on the outstanding stock options is 4.8 years. As of December 31, 2024, the weighted average exercise price of the vested and exercisable stock options was $20.27 and had an aggregate intrinsic value of $5.3 million. The Company did not grant any stock options during the twelve months ended December 31, 2024, twelve months ended December 31, 2023, and nine months ended December 31, 2022. The Company utilizes the Black-Scholes option valuation model for estimating the fair value of its stock options and these stock options either vest on a cliff-basis after three years or in equal parts over four years, depending on the award agreement terms.

Retirement Benefits [Abstract]
DEFINED CONTRIBUTION AND PENSION PLANS	DEFINED CONTRIBUTION AND PENSION PLANS BHL and Bristow International Aviation (Guernsey) Limited (“BIAGL”) each have a defined contribution plan available for new hires. The Company’s contributions to its defined contribution plans were $30.4 million, $28.4 million and $15.7 million for the twelve months ended December 31, 2024, twelve months ended December 31, 2023 and nine months ended December 31, 2022, respectively. Defined Benefit Plans The Defined Benefit Pension Plans were closed to future accrual as of February 1, 2004 and replaced by the defined contribution plans described above. Prior to replacement, the Defined Benefit Pension Plans covered employees of Bristow Aviation and BIAGL employed on or before December 31, 1997. The benefits for participants in the Defined Benefit Pension Plans were based on the employee’s annualized average last three years’ pensionable salaries up to February 1, 2004, increasing thereafter in line with price inflation, subject to maximum increases of 5% per year over the period to retirement. The benefits also receive increase post-retirement based on retail price inflation, subject to a maximum increase of 5% per year. Plan assets are held in separate funds administered by the plans’ trustee (the “Plan Trustee”), which are primarily invested in equities, debt securities and cash. The measurement date adopted is December 31, and resulting gains or losses are amortized over the average remaining life expectancy of the plan members. The following table shows the activity associated with the projected benefit obligation and the fair value of plan assets in addition to the defined benefit retirement plans’ funded status (in thousands): Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Change in benefit obligation: Projected benefit obligation (PBO) at beginning of period $ 363,315 $ 367,609 $ 529,956 Service cost 51 42 663 Interest cost 14,842 17,406 8,987 Actuarial loss (gain) (23,922) (17,939) (107,835) Benefit payments and expenses (24,159) (25,771) (18,481) Effect of exchange rate changes (6,382) 21,968 (45,681) Projected benefit obligation (PBO) at end of period $ 323,745 $ 363,315 $ 367,609 Change in plan assets: Fair value of assets at beginning of period $ 366,630 $ 347,520 $ 511,786 Actual return on assets (18,799) 9,836 (113,510) Employer contributions 11,272 14,278 11,725 Benefit payments and expenses (24,159) (25,771) (18,481) Effect of exchange rate changes (6,439) 20,767 (44,000) Fair value of assets at end of period $ 328,505 $ 366,630 $ 347,520 Reconciliation of funded status: Accumulated benefit obligation (ABO) $ 323,745 $ 363,315 $ 367,609 Projected benefit obligation (PBO) $ 323,745 $ 363,315 $ 367,609 Fair value of assets (328,505) (366,630) (347,520) Net recognized pension liability (asset) $ (4,760) $ (3,315) $ 20,089 Amounts recognized in accumulated other comprehensive loss $ 12,150 $ (7,528) $ 12,441 The service cost component is reported in the Company’s consolidated statements of operations in general and administrative expenses.

The expected rate of return assumptions have been determined following consultation with the Company’s actuarial advisors. In the case of bond investments, the rates assumed have been directly based on market redemption yields at the measurement date, and those on other asset classes represent expected investment returns based on investment modelling. Under UK and Guernsey legislation, it is the Plan Trustee who is responsible for the investment strategy of the plans, although day-to-day management of the assets is delegated to a team of regulated investment fund managers. The Plan Trustee of the Bristow Staff Pension Scheme (the “Scheme”) aims to invest the assets of the Scheme prudently so that the benefits promised to members are provided. In setting the investment strategy, the Trustee first considered the lowest risk asset allocation that it could adopt in relation to the Scheme’s liabilities. The types of investments are held, and the relative allocation of assets to investments is selected, in light of the liability profile of the Scheme, its cash flow requirements, the funding level and the Plan Trustee’s stated objectives. In addition, in order to avoid an undue concentration of risk, assets are diversified within and across asset classes.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company’s basic earnings (losses) per common share are computed by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding during the relevant period. Diluted earnings (losses) per common share of the Company are computed by dividing income available to common stockholders by the weighted average number of common shares issued and outstanding, inclusive of the effect of potentially dilutive securities (such as options to purchase common shares and restricted stock units and awards which were outstanding during the period but were anti-dilutive) through the application of the treasury method and/or the if-converted method, when applicable. The following table shows the computation of basic and diluted earnings per share (in thousands, except and per share amounts): Twelve Months Ended December 31, 2024 Twelve Months Ended December 31, 2023 Nine Months Ended Income (loss): Net income (loss) attributable to Bristow Group Inc. $ 94,797 $ (6,780) $ 13,528 Shares of common stock: Weighted average shares of common stock outstanding – basic 28,515 28,139 28,066 Net effect of dilutive stock 1,037 — 508 Weighted average shares of common stock outstanding – diluted (1) 29,552 28,139 28,574 Earnings (losses) per common share - basic $ 3.32 $ (0.24) $ 0.48 Earnings (losses) per common share - diluted $ 3.21 $ (0.24) $ 0.47 ______________________ (1) Excludes weighted average common shares of 28,378 for the twelve months ended December 31, 2024, 1,920,901 for the twelve months ended December 31, 2023 and 1,276,783 for the nine months ended December 31, 2022 for certain share awards as the effect of their inclusion would have been antidilutive.

Segment Reporting [Abstract]
SEGMENT AND GEOGRAPHIC AREA INFORMATION	SEGMENT AND GEOGRAPHIC AREA INFORMATION The Company has three reportable segments: Offshore Energy Services, Government Services and Other Services. The Offshore Energy Services segment provides aviation services to, from and between offshore energy installations globally. The Government Services segment provides SAR and support helicopter services to government agencies globally. The Other Services segment is primarily comprised of fixed wing services, dry-leasing of aircraft to third-party operators and part sales. Corporate includes unallocated overhead costs that are not directly associated with the Company’s reportable segments. The Company previously reported only one segment, aviation services. As a result the expansion of the Company’s government services contracts, the Company reevaluated the factors used to identify its reportable segments, which includes end customer profile, management responsibility and contract dynamics, and realigned its business into three operating segments discussed below. The Company’s Chief Executive Officer, who is the Chief Operating Decision Maker (“CODM”), uses segment operating income, in addition to other measures, to asses segment performance and allocate resources. Financial information by segment for the twelve months ended December 31, 2024 and 2023 and for the nine months ended December 31, 2022 is summarized below (in thousands): Offshore Energy Services

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Our cybersecurity strategy, which is effected through our Cybersecurity Risk Management Model, prioritizes the security and protection of our information technology networks and systems, through the detection, analysis and response to known, anticipated or unexpected threats and effective management of security risks. Our Cybersecurity Risk Management Model provides for four levels of industry-standard response activities to protect the Company against cyber threats. These are: 1. Policy Framework: Our information security practices include development, implementation, and improvement of policies and procedures to safeguard information and ensure availability of critical data and systems, including our Information Security Policy, which establishes guidelines for the safe and secure use of the Company’s information systems and data, and our Electronic Communication Policy, which outlines the responsibilities of those using the Company’s network and IT equipment. Employees and third-party service providers are required to comply with our Information Security Policy and our Electronic Communication Policy. 2. Awareness Programs: All employees participate in an ongoing program of mandatory annual training and receive periodic communications regarding the cybersecurity environment to increase awareness throughout the Company. We also implemented an enhanced annual training program for specific specialized employee populations. 3. Security Engineering: We leverage a combination of the International Organization for Standardization (the “ISO”) best practice standards and other global standards, including Control Objectives for Information and Relevant Technology, to measure our security posture and manage risk. In addition, we completed several cybersecurity-related initiatives such as multifactor authentication and the ISO 27001 certification, which is globally recognized as one of the highest standards of compliance and control for information security management systems. We have also implemented critical preventive measures, such as monthly phishing simulations, email and endpoint security and monitoring, database encryption, continuous patching, and network firewall security using both internal resources and independent third-party service providers. 4. IT Resiliency: Our IT Team has formalized disaster recovery processes, business continuity procedures and an incident response plan. These processes account for risks associated with third parties that provide IT services, process information on our behalf, or have access to our information systems. Our Data Privacy Officer is responsible for leadership, compliance, and oversight of applicable cyber and privacy laws and policies, which are designed to protect data belonging to our employees and customers and the Company’s information security; while our IT Cyber Incident Management Team oversees Bristow’s cyber incident response and remains in close contact with the Executive Leadership Team and the Audit Committee throughout the cyber incident resolution process. Our IT Steering Committee is responsible for reviewing, approving and funding IT projects, including cybersecurity initiatives. This committee consists of five (5) members: the Chief Information Officer, the President and Chief Executive Officer, the Chief Financial Officer, the Chief Operating Officer, Government Services and the Chief Operating Officer, Offshore Energy Services. The Chief Executive Officer, with the assistance of the other members of the executive leadership team, is responsible for, among other risk management measures, implementing measures designed to ensure the safety standards for personnel, information technology systems and data security, the environment and property in performing the Company’s operations.

Cybersecurity Risk Management Processes Integrated [Flag]	true
Cybersecurity Risk Management Processes Integrated [Text Block]	Our cybersecurity strategy, which is effected through our Cybersecurity Risk Management Model, prioritizes the security and protection of our information technology networks and systems, through the detection, analysis and response to known, anticipated or unexpected threats and effective management of security risks. Our Cybersecurity Risk Management Model provides for four levels of industry-standard response activities to protect the Company against cyber threats. These are: 1. Policy Framework: Our information security practices include development, implementation, and improvement of policies and procedures to safeguard information and ensure availability of critical data and systems, including our Information Security Policy, which establishes guidelines for the safe and secure use of the Company’s information systems and data, and our Electronic Communication Policy, which outlines the responsibilities of those using the Company’s network and IT equipment. Employees and third-party service providers are required to comply with our Information Security Policy and our Electronic Communication Policy. 2. Awareness Programs: All employees participate in an ongoing program of mandatory annual training and receive periodic communications regarding the cybersecurity environment to increase awareness throughout the Company. We also implemented an enhanced annual training program for specific specialized employee populations. 3. Security Engineering: We leverage a combination of the International Organization for Standardization (the “ISO”) best practice standards and other global standards, including Control Objectives for Information and Relevant Technology, to measure our security posture and manage risk. In addition, we completed several cybersecurity-related initiatives such as multifactor authentication and the ISO 27001 certification, which is globally recognized as one of the highest standards of compliance and control for information security management systems. We have also implemented critical preventive measures, such as monthly phishing simulations, email and endpoint security and monitoring, database encryption, continuous patching, and network firewall security using both internal resources and independent third-party service providers. 4. IT Resiliency: Our IT Team has formalized disaster recovery processes, business continuity procedures and an incident response plan. These processes account for risks associated with third parties that provide IT services, process information on our behalf, or have access to our information systems.

BASIS OF PRESENTATION, AND SUMM

BASIS OF PRESENTATION, AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities. Unless the context otherwise indicates, references herein to the “Company” refer to the entity currently known as Bristow Group Inc. and formerly known as Era Group Inc., together with all of its current subsidiaries. Change in Fiscal Year End Effective January 1, 2023, the Company’s fiscal year end changed from March 31st to December 31st. As a result of this change, the Company filed audited financial statements for the nine-month transition period from April 1, 2022 to December 31, 2022, on a Transition Report on Form 10-KT, filed with the Securities and Exchange Commission (“SEC”) on March 9, 2023, and subsequently, filed an Annual Report on Form 10-K for the twelve months ended December 31, 2023, on March 6, 2024. The consolidated financial information for the twelve months ended December 31, 2024, twelve months ended December 31, 2023, and nine months ended December 31, 2022 has been prepared by the Company in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the SEC on this Annual Report on Form 10-K.
Basis of Consolidation	Basis of Consolidation The consolidated financial statements include the accounts of Bristow Group Inc., its wholly and majority-owned subsidiaries and entities that meet the criteria of variable entities (“VIEs”) of which the Company is the primary beneficiary. All significant inter-company accounts and transactions are eliminated in consolidation.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure on contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and those differences may be material.
Reclassifications	Reclassifications Certain amounts reported for prior periods in the consolidated financial statements have been reclassified to conform with the current period’s presentation.
Cash Equivalents	Cash Equivalents
Restricted Cash	Restricted Cash The Company considers amounts deposited in escrow accounts at the end of each period as restricted cash. The Company’s restricted cash balances typically include certain payroll taxes for employee salaries in certain jurisdictions as outlined by local requirements and are shown as a separate line item in the consolidated balance sheet.
Trade Receivables and Current Expected Credit Losses	Trade Receivables and Current Expected Credit Losses The Company’s customers are primarily major integrated, national and independent offshore energy companies and government agencies. The Company designates trade receivables as a single pool of assets based on their short-term nature, similar customer base and risk characteristics. Customers are typically granted credit on a short-term basis, and related credit risks are considered minimal. The Company conducts periodic quantitative and qualitative analysis on historic customer payment trends, customer credit ratings and foreseeable economic conditions. Historically, losses on trade receivables have been immaterial and uncorrelated to each other. Based on these analyses, the Company decides if additional reserve amounts are needed against the trade receivables asset pool on a case by case basis. When collection efforts have been exhausted, trade receivables and the associated allowance for doubtful accounts are removed from accounts receivable.
Inventories	Inventories
Property and equipment	Property and equipment Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful life of the asset to an estimated salvage value. With respect to helicopters, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life. The Company reviews the estimated useful lives and salvage values of its property and equipment on an ongoing basis for any changes in estimates. The Company performs an impairment analysis on long-lived assets used in operations when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. The Company’s long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If an impairment is indicated for the asset group classified as held and used, an impairment evaluation will be performed. Asset impairment evaluations are based on estimated undiscounted cash flows over the remaining useful life for the assets being evaluated. If the sum of the expected future cash flows is less than the carrying amount of the asset group, the Company would be required to recognize an impairment loss. For aircraft types that are still operating where management has made the decision to sell or abandon the aircraft type at a fixed date, an analysis is completed to determine whether depreciation needs to be accelerated or additional depreciation recorded for an expected reduction in residual value at the planned disposal date.
Investments in Unconsolidated Affiliates	Investment in Unconsolidated Affiliates The Company uses a measurement alternative approach for equity investments without readily determinable fair values. The alternative method measures equity investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions in a similar investment of the same issuer. The Company performs regular reviews of each unconsolidated affiliate investee’s financial condition, the business outlook for its products and services and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties raising capital to continue operations, the investment is written down to fair value.
Leases	Leases The Company recognizes a right-of-use (“ROU”) asset and a lease liability on its consolidated balance sheets for leases under which it is the lessee, after applying the short-term lease exemption. Operating lease ROU assets and liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. For the applied discount rate, the Company uses its incremental borrowing rate based on information available at commencement date if the rate implicit in the lease cannot be readily determined.
Contract Fulfillment Costs	Contract Fulfillment Costs Costs to fulfill a contract with a customer incurred in advance of the commencement of a new contract are recognized as an asset and amortized on a straight-line basis over the life of the contract if the costs are directly related to the new contract, the costs are specifically identifiable, the costs generate or enhance resources of the entity and are expected to be recovered by the Company. These deferred costs are included in other long-term assets with the amount due for amortization within a year reflected in prepaid expenses and other current assets on the consolidated balance sheets. The balance is amortized through operating expense on the consolidated statements of operations.
Intangible Assets	Intangible Assets
Contingencies	Contingencies The Company establishes reserves for estimated loss contingencies when it believes a loss is probable and the amount of the loss can be reasonably estimated. The Company’s contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities and are adjusted as a result of changes in facts or circumstances that become known or changes in previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information that becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current year. Should the outcome differ from the Company’s assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized. Legal costs related to contingent liabilities are expensed as incurred.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method.
Derivative Financial Instruments	Derivative Financial Instruments The Company records changes in fair value of derivatives designated as cash flow hedges in accumulated other comprehensive income (loss) in its consolidated balance sheets until the forecasted transaction occurs. When the forecasted transaction affects earnings, the Company reclassifies the related gain or loss on the cash flow hedges to earnings. The Company evaluates hedge effectiveness at the inception of the hedge prospectively, and on an ongoing basis both retrospectively and prospectively. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, it will reclassify the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) to earnings.
Maintenance and Repairs	Maintenance and Repairs The Company generally charges maintenance and repair costs, including major helicopter component overhaul costs, to earnings as the costs are incurred. However, certain helicopter components, such as engines and transmissions, are maintained by third-party vendors under contractual agreements also referred to as power-by-the-hour (“PBH”) maintenance agreements. Under these agreements, the Company is charged an agreed amount per hour of flying time related to maintenance, repair and overhaul of the parts and components covered. The costs charged under these contractual agreements are recognized in the period in which the flight hours occur. To the extent that the Company has not yet been billed for costs incurred under these arrangements, these costs are included in accrued maintenance and repairs on its consolidated balance sheets. In the event the Company places a helicopter in a PBH program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown since the previous maintenance event. This buy-in charge is normally recorded as a prepaid expense and amortized as an operating expense over the remaining PBH contract period. From time to time, the Company receives credits from its original equipment manufacturers. The Company records these credits as a reduction in maintenance expense when the credits are utilized in lieu of cash payments for purchases or services, unless the credit represents a sales incentive offered to customers by the manufacturer. The cost of certain major overhauls on owned fixed-wing aircraft are capitalized when incurred and depreciated over the period until the next expected major overhaul. The cost of major overhauls on leased fixed-wing aircraft are charged to operating expense when incurred.
Share-Based Compensation	Share-Based Compensation The grant date fair value of share-based awards granted to employees is recognized as an employee compensation expense over the requisite service period on a straight-line basis. The amount of compensation expense ultimately recognized is based on the number of awards that meet the vesting conditions at the vesting date.
Foreign Currency Transactions	Foreign Currency Transactions The reporting currency for all of the Company’s foreign entities is the U.S. dollar. From time to time, the Company enters into transactions denominated in currencies other than its reporting currency. Gains and losses resulting from changes in currency exchange rates between the reporting currency and the currency in which a transaction is denominated are included in other, net in the Company’s consolidated statements of operations in the period which the currency exchange rates change. During the twelve months ended December 31, 2024 and 2023, the Company recognized foreign currency exchange losses of $8.9 million and of $10.7 million, respectively. During the nine months ended December 31, 2022, the Company recognized foreign currency exchange gains of $14.9 million. The functional currency for some subsidiaries outside the United States is the local currency. Financial statements of these subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities, with translation adjustments for non-monetary assets and liabilities reflected in equity. Under U.S. GAAP, an economy is considered highly inflationary if the cumulative inflation rate for a three-year period meets or exceeds 100 percent. If a foreign entity is considered to be in a highly inflationary economy, the financial statements of that entity are remeasured as though the functional currency were the reporting currency. The three-year inflation rate for Nigeria exceeded the three-year cumulative inflation rate of 100 percent as of September 30, 2024. Therefore, effective October 1, 2024, the Company began accounting for its Nigerian entity as a foreign entity operating in a country with a highly inflationary economy. Upon making the change in functional currency, the translated amounts for non-monetary assets and liabilities as of September 30, 2024 became the accounting basis for those balances. Translation adjustments for periods prior to October 1, 2024 will remain in equity. Going forward, monetary assets and liabilities denominated in the Nigerian naira are remeasured into U.S. dollars each reporting period, with remeasurement gains and losses recognized in other, net in the Company’s consolidated statements of operations. After applying highly inflationary accounting effective October 1, 2024, the Company recognized a loss on foreign exchange of $1.6 million in 2024.
Taxes	Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based upon temporary differences between the carrying amount and tax basis of the Company’s assets and liabilities and measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred income tax assets and liabilities of a change in the tax rates is recognized in income in the period in which the change occurs. The Company records a valuation allowance when it believes that it is more-likely-than-not that any deferred income tax asset created will not be realized.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not listed below were assessed and determined as not applicable to the Company’s consolidated financial position or result of operations. In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), requiring a footnote disclosure about specific expenses by requiring public business entities to disaggregate, in a tabular presentation, each relevant expense caption on the face of the income statement that includes purchases of inventory, employee compensation, depreciation and intangible asset amortization. The tabular disclosure would also include certain other expenses, when applicable. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027 (as amended in the FASB update in January 2025 in ASU 2025-01). The Company is evaluating the potential impact of the adoption of this ASU on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The purpose of ASU 2023-09 is to enhance the transparency and decision usefulness of income tax disclosures to investors and other allocators of capital. The objectives of the amendment is to provide information to better assess how an entity’s operations and related tax risk and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This standard will be effective prospectively for fiscal years beginning after December 15, 2024. The Company has evaluated the impact of adopting this ASU on its consolidated financial statements and determined adoption will not have a material impact and additional rate reconciliation disclosures will be included, beginning with its 2025 Annual Report on Form 10-K. In November 2023, the FASB issued ASU 2023-07 - Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU applies to all public entities that are required to report segment information in accordance with Topic 280 and requires the disclosure of significant segment expenses on an annual and interim basis, incremental disclosures of measures of segment profit or loss and the identification of the Company’s chief operating decision maker. This standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this ASU beginning with this Annual Report on Form 10-K. See Note 17 — Segments in this Annual Report on Form 10-K for the added disclosures.
Revenue Recognition	Revenue Recognition Revenues are recognized over time as the contracted aviation services are performed for a customer, when the transaction price is determined, and collection has occurred or is probable of occurring. A majority of the Company’s revenues are generated through two types of contracts: helicopter services and fixed wing services. The Company typically invoices customers on a monthly basis, and the term between invoicing and when the payment is due is typically between 30 and 60 days for helicopter services and fixed wing charter customers. Payment is made at the point of sale for fixed wing regular passenger transport customers. Deferred revenues are primarily generated by fixed wing services where customers pay for tickets in advance of receiving the Company’s services and from advanced payments from helicopter services customers. Helicopter services — Revenues from helicopter services are recognized over time based on contractual rates as the helicopter services are performed. Revenues are primarily derived from fixed-term contracts which typically have original terms of one Fixed wing services — The Company provides fixed wing transportation services through regular passenger transport (scheduled airline service with individual ticket sales) and charter services. Revenues are recognized as service is provided or in the period in which the right to travel expires, which is determined by the terms and conditions of the ticket. Both chartered and scheduled airline service revenues are recognized net of passenger taxes and discounts. Revenue Recognition The Company’s customers are primarily major integrated, national and independent offshore energy companies and government agencies. Revenues are generally recognized when the Company satisfies its performance obligations by providing aviation services to its customers in exchange for consideration. The Company disaggregates its revenues by operating segment.
