Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION, CONSOLIDATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION, CONSOLIDATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The condensed consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities. On January 23, 2020, Era Group Inc. (“Era”), Ruby Redux Merger Sub, Inc., a wholly owned subsidiary of Era (“Merger Sub”) and Bristow Group Inc. (“Old Bristow”) entered into an Agreement and Plan of Merger, as amended on April 22, 2020 (the “Merger Agreement”). On June 11, 2020, the merger (the “Merger”) contemplated by the Merger Agreement was consummated and Merger Sub merged with and into Old Bristow, with Old Bristow continuing as the surviving corporation and as a direct wholly owned subsidiary of Era. Following the Merger, Era changed its name to Bristow Group Inc., and Old Bristow changed its name to Bristow Holdings U.S. Inc. Unless the context otherwise indicates, in this Quarterly Report on Form 10-Q, references to: • the “Company”, “Combined Company,” “Bristow”, “we”, “us” and “our” refer to the entity currently known as Bristow Group Inc. and formerly known as Era Group Inc., together with all of its current subsidiaries; • “Old Bristow” refers to the entity formerly known as Bristow Group Inc. and now known as Bristow Holdings U.S. Inc., together with its subsidiaries prior to the consummation of the Merger; and • “Era” refers to Era Group Inc. (currently known as Bristow Group Inc., the parent of the Combined Company) and its subsidiaries prior to consummation of the Merger. Pursuant to the United States (“U.S.”) generally accepted accounting principles (“GAAP”), the Merger was accounted for as an acquisition by Old Bristow of Era even though Era was the legal acquirer and remained the ultimate parent of the Combined Company. As a result, upon the closing of the Merger, Old Bristow’s historical financial statements replaced Era’s historical financial statements for all periods prior to the completion of the Merger, and the financial condition, results of operations, comprehensive income and cash flows of Era have been included in those financial statements since June 12, 2020. Any reference to comparative period disclosures in the Quarterly Report on Form 10-Q refers to Old Bristow. Effective upon the closing of the Merger, the Company changed its fiscal year-end from December 31 to March 31, to correspond with Old Bristow’s fiscal year-end. The Company’s fiscal year ends March 31, and fiscal years are referenced based on the end of such period. Therefore, the fiscal year ending March 31, 2021 is referred to as “fiscal year 2021”. The condensed consolidated financial information for the three and six months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor) has been prepared by the Company in accordance with GAAP and pursuant to the rules and regulations of the SEC for interim financial information reporting on Quarterly Form 10-Q and Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP in the United States (“U.S.”) have been condensed or omitted from that which would appear in the annual consolidated financial statements. These condensed consolidated financial statements should be read in conjunction with the financial statements and related notes thereto included in the Company’s Current Report on Form 8-K for the fiscal year ended March 31, 2020 (the “fiscal year 2020 Financial Statements”) filed with the Securities and Exchange Commission (the “SEC”) on June 17, 2020, referred to hereafter as the “ Financial Statement Form 8-K”. The preparation of these financial statements and accompanying footnotes requires the Company to make estimates and assumptions; however, they include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair presentation of the condensed consolidated balance sheet, the condensed consolidated statements of operations and comprehensive loss, the condensed consolidated statements of cash flows and the condensed consolidated statements of changes in stockholders’ investment and mezzanine equity. Operating results for the interim period presented are not necessarily indicative of the results that may be expected for the entire fiscal year. The condensed consolidated financial information found on this Quarterly Form 10-Q has not been audited by the Company’s independent registered public accounting firm. 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 interest entities (“VIEs”) of which the Company is the primary beneficiary. All significant inter-company accounts and transactions are eliminated in consolidation. Coronavirus Update The outbreak of the disease caused by the novel coronavirus (“COVID-19”) caused a significant decrease in oil and natural gas prices resulting from demand weakness and over supply and also caused significant disruptions and volatility in the global marketplace in calendar year 2020. These conditions are expected to continue for at least the near future. The depressed oil and natural gas price environment was initially exacerbated by decisions by large oil producing countries that have now been altered, but the resolution has not led to a meaningful increase in oil and gas prices, which remain below historical averages. For additional information, see Part II Item 1A “Risk Factors” and the “Recent Developments” section of Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”). Emergence from Voluntary Reorganization under Chapter 11 On May 11, 2019 (the “Petition Date”), Old Bristow and certain of its subsidiaries (collectively the “Debtors”) filed voluntary petitions (the “Chapter 11 Cases”) in the U.S. Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) seeking relief under Chapter 11 of Title 11 of the U.S. Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 Cases were jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. During the pendency of the Chapter 11 Cases, the Debtors continued to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. On August 1, 2019, the Debtors filed with the Bankruptcy Court their Joint Chapter 11 Plan of Reorganization, and on August 20, 2019, the Debtors filed their Amended Joint Chapter 11 Plan of Reorganization (as further modified on August 22, 2019, the “Amended Plan”) and the related Disclosure Statement (as further modified on August 22, 2019, the “Amended Disclosure Statement”). On October 8, 2019, the Bankruptcy Court entered an order approving the Amended Disclosure Statement and confirming the Amended Plan. The effective date of the Amended Plan (the “Effective Date”) occurred on October 31, 2019 at which point the Debtors emerged from the Chapter 11 Cases. Claims under the Bankruptcy Court approved debtor in possession (DIP) financing Old Bristow obtained while in bankruptcy were settled with the issuance of new common stock (the “Old Bristow Common Stock”) and new preferred stock (the “Old Bristow Preferred Stock”), both at a par of $0.0001 , pursuant to the Amended Plan. Upon Old Bristow’s emergence from bankruptcy, Old Bristow adopted fresh-start accounting in accordance with provisions of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) No. 852, “Reorganizations” (“ASC 852”), which resulted in Old Bristow becoming a new entity for financial reporting purposes on the Effective Date. Upon the adoption of fresh-start accounting, the Company’s assets and liabilities were recorded at their fair values as of the fresh-start reporting date, October 31, 2019. As a result of the adoption of fresh-start accounting, Old Bristow’s consolidated financial statements subsequent to October 31, 2019 may not be comparable to the consolidated financial statements prior to October 31, 2019. In this Quarterly Report on Form 10-Q, references to: • “Predecessor” refer to Old Bristow on and prior to October 31, 2019; and • “Successor” refer to the reorganized Old Bristow on and after November 1, 2019 until completion of the Merger and after completion of the Merger refer to the Combined Company. Current Expected Credit Losses (“CECL”) The Company’s customers are primarily international, independent and major integrated exploration, development and production companies, third party helicopter operators 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. Trade receivables are deemed uncollectible and removed from accounts receivable and the allowance for doubtful accounts when collection efforts have been exhausted. As of September 30, 2020 (Successor), the Company did not reserve any additional amounts for CECL. As of September 30 and March 31, 2020 (Successor), the allowance for doubtful accounts related to accounts receivables was $1.3 million and $0.4 million , respectively, and primarily related to a customer in the U.S. Gulf of Mexico. Guarantors of Securities In March 2020, the SEC amended Rule 3-10 and 3-16 of Regulation S-X, CFR 210.1-01 through 210.3-16, regarding financial disclosure requirements for debt securities issued in registered offerings involving subsidiaries of the registrant as either issuers or guarantors. This amended rule narrows the circumstances that require separate financial statements or summarized financial disclosures of issuers and subsidiary guarantors and simplifies the summarized disclosures required in lieu of those statements. Under the new rule, comparative period information is no longer required. As a result of this amended rule, the Company has included narrative disclosures in lieu of separate financial statements. The Company has early adopted this new rule and has elected to provide the simplified disclosure related to its 7.750% Senior Notes due 2022 within the MD&A. Recent Accounting Pronouncements The Company considers the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s consolidated financial position or results of operations. Adopted In June 2016, the FASB issued ASU No. 2016-13, 2019-04, “Measurement of Credit Losses on Financial Instruments” (ASU No. 2016-13), which sets forth the current expected credit loss model, a new forward-looking impairment model for certain financial instruments based on expected losses rather than incurred losses. The ASU is effective for interim and annual periods beginning after December 15, 2019, and early adoption of the standard was permitted. Entities were required to adopt ASU No. 2016-13 using a modified retrospective approach, subject to certain limited exceptions. Upon evaluating the impact of this ASU, the Company concluded that no additional reserves were necessary as historical losses were immaterial, and, based on the qualitative and quantitative analysis performed in accordance with ASC 326 requirements, the Company determined there was no reasonable expectation of credit losses associated with the Company’s trade receivables in the foreseeable future. ASU No. 2016-13 was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurements” (Topic 820) modifying the disclosure requirements on fair value measurements. The amendment modifies, removes, and adds several disclosure requirements on fair value measurements in ASC 820, Fair Value Measurement. The amendment will be effective for the Company in fiscal year 2022, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020 prospectively, and such adoption did not have a material impact on its condensed consolidated financial statements. In August 2018, the FASB modified ASU No. 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans” (Subtopic 715-20), for changes to disclosure requirements for employers that sponsor defined benefit pension plans. Certain disclosure requirements were removed and certain disclosure requirements were added. The amendment also clarifies disclosure requirements for projected benefit obligations and accumulated benefit obligations in excess of respective plan assets. The amendment is effective beginning in the Company’s fiscal year 2021 financial statements, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020 by removing the weighted-average expected long-term rate of return on assets in this Quarterly Report. Annual disclosure requirements will be reflected in the Annual Report. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software” (Subtopic 350-40), providing guidance that addresses the accounting for implementation costs associated with a hosted service. The guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. The amendment is effective beginning in fiscal year 2021 financial statements, and early adoption is permitted. The guidance will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. This disclosure requirement was adopted effective April 1, 2020 prospectively, and such adoption did not have a material impact on its condensed consolidated financial statements. In October 2018, the FASB amended ASU No. 2018-17, “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (Topic 810), the guidance for determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in generally accepted accounting principles). Therefore, these amendments likely will result in more decision makers not consolidating VIEs. This amendment is effective beginning in the Company’s fiscal year 2021 financial statements, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-03, “Codification Improvements to Financial Instruments”, which makes improvements to financial instruments guidance. The standard is effective immediately for certain amendments and for fiscal years beginning after December 15, 2019. This accounting guidance was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740), new guidance to simplify the accounting for income taxes, which eliminates certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. This ASU also includes guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The standard will be effective for the Company in fiscal year 2022 and early adoption is permitted. The Company is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, “Investments-Equity Securities” (Topic 321), “Investments-Equity Method and Joint Ventures” Topic 323 and “Derivatives and Hedging” Topic 815 (ASU No. 2020-01) as an update to ASU No. 2016-01 “Financial Instruments-Overall”, further clarifying certain interactions between the guidance to account for certain equity securities under Topic 321, 323 and 815, and improve current GAAP by reducing diversity in practice and increasing comparability of accounting. The standard will be effective for the Company in fiscal year 2022, and early adoption is permitted. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform” (Topic 848). The guidance is intended to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The standard will be effective for the Company in fiscal year 2022. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, “Debt - Debt with Conversion and Other Options” (Subtopic 470-20) and “Derivatives and Hedging - Contracts in Entity's Own Equity” (Topic 815) as a means of simplifying and reducing the number of accounting models for convertible debt instruments and convertible preferred stock. The ASU also amends the guidance for derivatives scope exception for contracts in an entity's own equity. The goal being to reduce differences in accounting for similar contracts between different companies that are accounted for as derivatives by some and equity by others. The standard will be effective for the Company in fiscal year 2022. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS Era Group Inc. On June 11, 2020, the combination of Old Bristow with Era was successfully completed in an all-stock transaction with Era having issued shares of common stock (“Combined Company Common Stock”) to Old Bristow’s stockholders. The transaction was accounted for using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). In the Merger, Old Bristow merged with and into Merger Sub, a subsidiary of Era, with Old Bristow remaining as the surviving company and as a subsidiary of Era, the ultimate parent of the Combined Company. Era is one of the largest helicopter operators in the world and the longest serving helicopter transport operator in the U.S., primarily servicing offshore oil and gas production platforms, drilling rigs and other installations. The transaction was structured as an all-stock, reverse-triangular merger, whereby Era issued shares of Combined Company Common Stock to Old Bristow stockholders, allowing it to qualify as a tax free reorganization for U.S. federal income tax purposes. Following the Merger, Era changed its name to Bristow Group Inc., and its common stock continued to trade on the NYSE under the new ticker symbol VTOL. While Era was the legal acquirer in the Merger, Old Bristow was determined to be the accounting acquirer, based upon the terms of the Merger and other considerations including that: (i) immediately following completion of the Merger, Old Bristow stockholders owned approximately 77% of the outstanding shares of Combined Company Common Stock and pre-Merger holders of Era common stock (“Era Common Stockholders”) owned approximately 23% of the outstanding shares of Combined Company Common Stock and (ii) the board of directors of the Company consists of eight directors, including six Old Bristow designees. The Merger was accounted for under the acquisition method of accounting under ASC 805, Business Combinations. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The Company completed its assessment of the fair value of assets acquired and liabilities assumed within the one-year period from the date of acquisition. The Company recorded measurement period adjustments due to additional information received primarily related to aircraft, redeemable noncontrolling interest and income taxes, resulting in an increase in bargain purchase gain of $5.7 million . The acquisition date fair value of the consideration transferred consisted of the following (in thousands): Fair value of Combined Company Common Stock issued (1) $ 106,440 Fair value of accelerated stock awards (2) 2,067 Fair value of exchanged stock awards (3) 228 Total consideration transferred $ 108,735 Fair value of redeemable noncontrolling interest 1,501 Total fair value of Era $ 110,236 ___________________________ (1) Represents the fair value of Combined Company Common Stock retained by Era Common Stockholders based on the closing market price of Era shares on June 11, 2020, the acquisition date. (2) Represents the fair value of restricted share awards of Combined Company Common Stock held by Era employees that were accelerated upon consummation of the Merger. (3) Represents the amount of the fair value of restricted share awards of Combined Company Common Stock held by Era employees relating to the pre-Merger vesting period. The following table summarizes the fair values of assets acquired and liabilities assumed as of the date of acquisition, June 11, 2020 (in thousands): Assets acquired: Cash and cash equivalents $ 120,236 Accounts receivable from non-affiliates 35,079 Prepaid expenses and other current assets 17,598 Inventories 8,826 Property and equipment 223,256 Right-of-use assets 8,395 Other assets 14,792 Total assets acquired $ 428,182 Liabilities assumed: Accounts payable $ 9,686 Accrued wages, benefits and related taxes 8,319 Income taxes payable 1,791 Deferred revenue 236 Current portion of operating lease liabilities 1,711 Other accrued liabilities 18,474 Short-term borrowings and current maturities of long-term debt 17,485 Long-term debt, less current maturities 136,704 Other liabilities and deferred credits 1,404 Deferred taxes 34,198 Long-term operating lease liabilities 6,845 Total liabilities and redeemable noncontrolling interest assumed $ 236,853 Net assets acquired $ 191,329 The Merger resulted in a gain on bargain purchase due to the estimated fair value of the identifiable net assets acquired exceeding the purchase consideration transferred by $81.1 million and is shown as a gain on bargain purchase on the condensed consolidated statements of operations. The bargain purchase was a result of a combination of factors including depressed oil and gas prices and market volatility linked to the COVID-19 pandemic between the initial announcement and consummation of the Merger. Specifically, the Era share price declined from $8.59 to $5.16 between the last trading day prior to the Merger announcement and the date the Merger closed. The aggregate Merger consideration was based on an exchange ratio that was fixed and did not fluctuate in the event that the value of Old Bristow’s common stock increased or Era’s common stock decreased, between the date of the Merger agreement and consummation of the Merger. The following unaudited supplemental pro forma combined financial information presents the Company’s results of operations for the three and six months ended September 30, 2020 , as though the Merger had occurred on November 1, 2019, the effective date of Old Bristow’s emergence from the Chapter 11 Cases. The unaudited pro forma financial information is as follows (in thousands) (1) : Successor Three Months Ended Six Months Ended Total revenues $ 304,640 $ 609,963 Net income $ (34,333 ) $ (10,015 ) Net income attributable to Bristow Group Inc. $ (34,200 ) $ (9,828 ) _____________________ (1) As a result of the Merger, the Company was required to dispose of its investment in Lider which occurred on August 2020. The Company had recorded an impairment in June 2020 of $18.7 million related to the future disposition of the investment. This impairment has been excluded from the pro forma combined Net income and Net income attributable to Bristow Group Inc. due to its nonrecurring nature. The amounts of revenue and earnings of Era included in the Company’s condensed consolidated statements of operations from the acquisition date of June 11, 2020 are as follows (in thousands): Successor Three Months Ended June 11, 2020 - September 30, 2020 Total revenues $ 41,817 $ 50,677 Net loss $ (954 ) $ (5,247 )

In connection with the sale of certain aircraft during the three months ended September 30, 2020 , the Company agreed to sell certain related equipment and inventory. As a result, the Company recognized a $12.4 million loss on impairment to record those equipment and inventory items at the expected sales value. The equipment and inventory did not transfer title as of September 30, 2020 ; however, title is expected to transfer prior to March 31, 2021.

REVENUE RECOGNITION

REVENUE RECOGNITION	6 Months Ended

Revenue Recognition [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNTION Revenue Recognition The Company derives its revenues primarily from oil and gas flight services and search and rescue services. A majority of the Company’s revenue is generated through two types of contracts: helicopter services and fixed wing services. Revenue is recognized when control of the identified distinct goods or services has been transferred to the customer, the transaction price is determined and allocated to the satisfied performance obligations and the Company has determined that collection has occurred or is probable of occurring. The Company determines revenue recognition by applying the following steps: 1. Identify the contract with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price; 4. Allocate the transaction price to the performance obligations; and 5. Recognize revenue as the performance obligations are satisfied. Operating revenue from the Company’s oil and gas line of service is derived mainly from fixed-term contracts with its customers. Fixed-term contracts typically have original terms of one to five years , subject to provisions permitting early termination by customers. Customers are typically invoiced on a monthly basis with payment terms of 30 - 60 days . The following table shows the total revenue related to third party customers (in thousands): Three Months Ended September 30, Six Months Ended September 30, Successor Predecessor Successor Predecessor 2020 2019 2020 2019 Revenue: Operating revenue from non-affiliates $ 282,060 $ 290,939 $ 528,189 $ 594,672 Operating revenue from affiliates 3,267 5,365 7,861 9,840 Reimbursable revenue from non-affiliates 8,918 13,536 17,603 30,136 Revenue from Contracts with Customers 294,245 309,840 553,653 634,648 Other revenue from non-affiliates 447 409 867 806 Other revenue from affiliates 9,948 7,971 20,313 15,942 Total Revenue $ 304,640 $ 318,220 $ 574,833 $ 651,396 Contract Assets, Liabilities and Receivables The Company generally satisfies performance of contract obligations by providing helicopter and fixed wing services to its customers in exchange for consideration. The timing of performance may differ from the timing of the customer’s payment, which results in the recognition of a contract asset or a contract liability. A contract asset exists when the Company has a contract with a customer for which revenue has been recognized (i.e., services have been performed), but customer payment is contingent on a future event (i.e., satisfaction of additional performance obligations). These contract assets are transferred to receivables when the right to consideration becomes unconditional. Contract liabilities relate to deferred revenue in which advance consideration is received from customers for contracts where revenue is recognized based on future performance of services. As of September 30 and March 31, 2020 (Successor), receivables related to services performed under contracts with customers were $173.7 million and $148.3 million , respectively. During the six months ended September 30, 2020 (Successor), the Company recognized $2.2 million of revenue from outstanding contract liabilities. Contract liabilities related to services performed under contracts with customers were $7.9 million and $4.9 million as of September 30, 2020 (Successor) and March 31, 2020 (Predecessor), respectively. Contract liabilities are primarily generated by fixed wing services where customers pay for tickets in advance of receiving the Company’s services and advanced payments from helicopter services customers. There were no contract assets as of September 30 and March 31, 2020 (Successor). There was $0.6 million and $1.0 million in revenues recognized from satisfied performance obligations related to prior periods (for example, due to changes in transaction price) for the three months and six months ended September 30, 2020 (Successor), respectively. Remaining Performance Obligations Remaining performance obligations represent firm contracts for which work has not been performed and future revenue recognition is expected. The table below discloses (1) the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period and (2) the expected timing to recognize this revenue (in thousands): Remaining Performance Obligations (Successor) Six Months Ending March 31, 2021 Fiscal Year Ending March 31, Total 2022 2023 2024 2025 and thereafter Outstanding Service Revenue: Helicopter contracts $ 223,773 $ 243,575 $ 198,487 $ 171,741 271,155 $ 1,108,731 Fixed wing contracts 718 — — — — 718 Total remaining performance obligation revenue $ 224,491 $ 243,575 $ 198,487 $ 171,741 271,155 $ 1,109,449 Although substantially all of the Company’s revenue is derived under contract, due to the nature of the business, the Company does not have significant remaining performance obligations as its contracts typically include unilateral termination clauses that allow its customers to terminate existing contracts with a notice period of 30 to 365 days. The table above includes performance obligations up to the point where the parties can cancel existing contracts. Any applicable cancellation penalties have been excluded. As such, the Company’s actual remaining performance obligation revenue is expected to be greater than what is reflected in the table above. In addition, the remaining performance obligation disclosure does not include expected consideration related to performance obligations of a variable nature (i.e., flight services) as they cannot be reasonably and reliably estimated.

VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES	VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES . A 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, and if not, the Company does not consolidate. As of September 30, 2020 (Successor), the Company had interests in five VIEs, Bristow Aviation Holdings Limited (“Bristow Aviation”), Impigra Aviation Holdings Limited (“Impigra”), Bristow Helicopters (Nigeria) Limited (“BHNL”), Pan African Airlines (Nigeria) Limited (“PAAN”) and YII 5668 Energy (“YII Energy”), of which the Company was the primary beneficiary, and had no interests in VIEs of which the Company was not the primary beneficiary. See Note 3 to the fiscal year 2020 condensed consolidated financial statements for a description of these VIEs and other investments in significant affiliates. Bristow Aviation — The Company owns 49% of Bristow Aviation’s common stock and a significant amount of its subordinated debt. Bristow Aviation is incorporated in England and, through its subsidiaries, holds all the outstanding shares in Bristow Helicopters Limited (“Bristow Helicopters”). Impigra, a British company owned 100% by U.K. Bristow employees is considered a VIE that the Company consolidates as the primary beneficiary and is expected to meet the requirements to satisfy a qualified U.K. investor requirement.

(2) The pre-Merger outstanding principal amount of Era’s promissory notes as of March 31, 2020 was $17.9 million . PK Air Debt — During the three and six months ended September 30, 2020 (Successor), the Company made $5.4 million and $10.6 million , respectively, in principal payments on the PK Air debt. Macquarie Debt — During the three and six months ended September 30, 2020 (Successor), the Company made $2.4 million and $4.8 million , respectively, in principal payments on the Macquarie debt. 7.750% Senior Notes — On December 7, 2012, Era Group issued $200.0 million aggregate principal amount of its 7.750% senior unsecured notes due December 15, 2022 (the “ 7.750% Senior Notes”) and received net proceeds of $191.9 million . Interest on the 7.750% Senior Notes is payable semi-annually in arrears on June 15 th and December 15 th of each year. The 7.750% Senior Notes may be redeemed at any time and from time to time at the applicable redemption prices set forth in the indenture governing the 7.750% Senior Notes, plus accrued and unpaid interest, if any, to the redemption date. The indenture governing the 7.750% Senior Notes contains covenants that restrict the Company’s ability to, among other things, incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem the Company’s capital stock, prepay, redeem or repurchase certain debt, make loans and investments, sell assets, incur liens, enter into transactions with affiliates, enter into agreements restricting its subsidiaries’ ability to pay dividends, and consolidate, merge or sell all or substantially all of our assets. In addition, upon a specified change of control trigger event or specified asset sale, the Company may be required to repurchase the 7.750% Senior Notes. The payment obligations under the 7.750% Senior Notes are fully and unconditionally guaranteed by certain of the Company’s subsidiaries. As of September 30, 2020 (Successor), the 7.750% Senior Notes had a carrying value of $137.5 million on the condensed consolidated balance sheets. In June 2020, in connection with and upon completion of the Merger, Era’s long-term debt less its current maturities were fair valued and a new value of $136.8 million was assigned to the 7.750% Senior Notes. Lombard Debt — During the three and six months ended September 30, 2020 (Successor), the Company made $3.1 million and $6.1 million , respectively, in principal payment on the Lombard debt. Promissory Notes — In 2010, Era entered into two promissory notes to purchase a heavy and medium helicopter, respectively. In December 2015, upon maturity of the notes, the then outstanding balances of $19.0 million and $5.9 million were refinanced. The notes require monthly principal payments of $0.1 million and less than $0.1 million with final payments of $12.8 million and $4.0 million , respectively. Both promissory notes are due in December 2020. Term Loan Agreement — In connection with the closing of the Merger on June 11, 2020, the Company fully repaid the Term Loan by making $61.5 million in principal payments and $0.6 million in prepayment premiums. 4½% Convertible Senior Notes due 2023 — Prior to May 11, 2019, the remaining debt discount was being amortized to interest expense over the term of the 4½% Convertible Senior Notes using the effective interest rate. The effective interest rate for April 1, 2019 to May 11, 2019 (Predecessor) was 11.0% . Interest expense related to the 4½% Convertible Senior Notes was as follows (in thousands): Predecessor Six Months Ended September 30, 2019 Contractual coupon interest $ 715 Amortization of debt discount 648 Total interest expense $ 1,363 As of May 11, 2019, Old Bristow determined that the 4½% Convertible Senior Notes were an allowed claim and therefore reclassified the balance to liabilities subject to compromise and discontinued accruing interest on these obligations. Contractual interest on the 4½% Convertible Senior Notes for the three and six months ended September 30, 2019 (Predecessor) was $1.6 million and $3.2 million , which is $1.6 million and $2.5 million in excess of reported interest expense for the three and six months ended September 30, 2019 (Predecessor). ABL Facility — On April 17, 2018, two of Old Bristow’s subsidiaries entered into an asset-backed revolving credit facility (the “ABL Facility”). The ABL Facility matures in April 2023 , subject to certain early maturity triggers related to maturity of other material debt or a change of control of the Company. Amounts borrowed under the ABL Facility are secured by certain accounts receivable owing to the borrower subsidiaries and the deposit accounts into which payments on such accounts receivable are deposited. On August 18, 2020, the Company entered into a Deed of Amendment and Restatement, Accession, Transfer, Resignation and Confirmation Agreement (the “ABL Amendment”) relating to the ABL Facility (as amended by the ABL Amendment, the “Amended ABL”), by and among the Company, Old Bristow, Bristow Norway AS, Bristow Helicopters Limited and Bristow U.S. LLC, as borrowers and guarantors, the financial institutions from time to time party thereto as lenders and Barclays Bank PLC, in its capacity as agent and security trustee. The ABL Amendment amends the ABL Facility in order to, among other things, (i) make available to the borrowers an additional “last in, last out” tranche of revolving loan commitments available to the borrowers under the Amended ABL in an aggregate amount not to exceed $5.0 million , (ii) replace Old Bristow with the Company as the parent guarantor under the Amended ABL and (iii) permit the accession at a later date of certain domestic subsidiaries of the Company as borrowers under the Amended ABL and the addition of certain of their receivables to the borrowing base and the collateral for the Amended ABL. The interest rates applicable to loans made under the “last in, last out” tranche of revolving commitments under the Amended ABL are equal to either: (a) the ABR (as defined in the Amended ABL) plus 2.50% per annum or (b) LIBOR or NIBOR (each as defined in the Amended ABL) plus 3.50% per annum. Swingline loans made under the “last in, last out” tranche of revolving commitments under the Amended ABL bear interest at the ABR Rate (as defined in the Amended ABL) plus 2.50% per annum. As a result of the ABL Amendment, the Amended ABL provides for commitments in an aggregate amount of $80.0 million . The Company retains the ability under the Amended ABL to increase the total commitments up to a maximum aggregate amount of $115.0 million , subject to the terms and conditions therein. As of September 30, 2020 (Successor), there were no outstanding borrowings under the Amended ABL nor had the Company made any draws during the three months ended September 30, 2020 (Successor). Letters of credit issued under the Amended ABL in the aggregate face amount of $9.2 million were outstanding on September 30, 2020 (Successor). LIBOR Transition — In 2020, a number of regulators in conjunction with the FASB and the U.S. Federal Reserve announced their intention to suspend and replace the use of LIBOR by the beginning of calendar year 2021. The effects of this transition from LIBOR to an alternative reference rate may impact the Company’s current indebtedness that is tied to LIBOR, in addition to the potential overall financial market disruption as a result of this phase-out. The Company is currently evaluating the potential effects of this announcement on its underlying debt, but it does not expect the impact to be material.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	6 Months Ended
	Sep. 30, 2020
Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value. 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. Assets and liabilities subject to fair value measurement are categorized into one of three different levels depending on the observability of the inputs employed in the measurement, as follows: • Level 1 – observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – inputs that reflect quoted prices for identical assets or liabilities in markets which are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 – unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. Old Bristow Preferred Stock Embedded Derivative The fair value of the Old Bristow Preferred Stock embedded derivative relied on the income approach which was derived from Level 3, unobservable inputs that required significant estimates, judgments and assumptions relating to the Company’s equity volatility, capitalization tables, term to exit and equity value. The Old Bristow Preferred Stock was converted into Old Bristow Common Stock immediately prior to consummation of the Merger. Changes in the fair value of the New Preferred Stock derivative liability, carried at fair value, are reported as change in fair value of the Preferred Stock derivative liability in the condensed consolidated statements of operations. For the six months ended September 30, 2020 (Successor), the Company recognized non-cash expense of approximately $15.4 million due to an increase in the Preferred Stock derivative liability related to the embedded derivative in the New Preferred Stock. The following table provides a rollforward of the preferred stock embedded derivative Level 3 fair value measurements for the six months ended September 30, 2020 (Successor): Significant Unobservable Inputs (Level 3) Derivative financial instruments: (in thousands) March 31, 2020 $ 286,182 Change in fair value (15,416 ) Preferred stock shares conversion (266,846 ) Share repurchases (3,920 ) September 30, 2020 $ — The Old Bristow Preferred stock embedded derivative considered settlement scenarios which are further defined in Note 11 to the condensed consolidated financial statements. A number of the settlement scenarios required a settlement premium. The specified premium depended on the timing of the liquidity event, ranging from a minimum of (a) 17% Internal Rate of Return (the “IRR”) (b) 2.1 x Multiple of Invested Capital (the “MOIC”) and (c) 14% Internal Rate of Return (the “IRR”) if the liquidity event is prior to 3 years , to (y) a 2.1 x MOIC and (z) 17% IRR if the liquidity event is in 5 years or more. The fair value for the embedded derivative was determined using a “with” and “without” approach, first determining the fair value of the Old Bristow Preferred Stock (inclusive of all bifurcated features) with the features and comparing it with the fair value of an instrument with identical terms to the Old Bristow Preferred Stock without any of the bifurcated features (i.e., the preferred stock host). The fair value of the Old Bristow Preferred Stock was estimated using an option pricing method (“OPM”) allocating the total equity value to the various classes of equity. As of June 11, 2020 (Successor), Old Bristow assumed an expected term of 6 years , a risk-free rate of 0.38% and volatility of 85% . Without the redemption or conversion features, the holders of the Old Bristow Preferred Stock would have had right to perpetual preferred with 10% paid-in-kind (“PIK”) dividends, or the right to any upside value from conversion into common stock if the value exceeded the minimum return provided for under the COD (as defined herein). The value of converting to common stock on the upside would be measured as the residual upon a liquidity event. Therefore, the fair value of the host was estimated as the value of the upside conversion into common shares, which was also estimated using the OPM. The valuation as of June 11, 2020 resulted in a decline in fair value of the Old Bristow Preferred Stock embedded derivative of $15.4 million from March 31, 2020 (Successor). On June 11, 2020, immediately before the Merger was executed, Old Bristow exercised its call right (the “Call Right’) pursuant to section 8 of the Certificate of Designation of the Old Bristow Preferred Stock (“COD”). This provision entitled Old Bristow to repurchase the shares upon a Fundamental Transaction (which included a merger or consolidation) for a repurchase price equal to (i) the Liquidation Preference plus (ii) the present value of the dividends that would have accrued from the call date to the 5th anniversary of the issuance date (had the Call Right not been exercised) multiplied by the Make-Whole Redemption Percentage (equal to 102% because the Call Right was exercised before the 3rd anniversary of the issuance date). Upon exercise of the Call Right, Old Bristow issued 5.17962 shares of Old Bristow Common Stock to the remaining holders of the Preferred Stock for each share of Preferred Stock held. The carrying values of the Old Bristow Preferred Stock were derecognized, including the Old Bristow Preferred Stock embedded derivative, and recognized the Old Bristow Common Stock issued to the holders of the Old Bristow Preferred Stock at its fair value. The difference between (a) the carrying value of the Old Bristow Preferred Stock embedded derivative plus the carrying value of the Old Bristow Preferred Stock host and (b) the fair value of the Old Bristow Common Stock paid as consideration for the Old Bristow Preferred Stock was recognized in retained earnings because the fair value of the Old Bristow Common Stock was less than the combined carrying values of the Old Bristow Preferred Stock host and embedded derivative. In addition, immediately prior to the Merger, Old Bristow repurchased 98,784 shares of the Old Bristow Preferred Stock and 142,721 shares of Old Bristow Common Stock. The repurchase of the Old Bristow Preferred Stock was accounted for in the same manner as the share-settled redemption described above in connection with the Merger. Fair Value of Debt The fair value of the Company’s debt has been estimated in accordance with the accounting standard regarding fair value. The fair value of the Company’s long-term debt was estimated using discounted cash flow analysis based on estimated current rates for similar types of arrangements. 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 value of the Company’s debt, excluding unamortized debt issuance costs, are as follows (in thousands): Successor Carrying Level 1 Level 2 Level 3 September 30, 2020 LIABILITIES PK Air Debt $ 198,217 $ — $ 205,627 $ — Macquarie Debt 145,232 — 153,119 — 7.750% Senior Notes 137,499 — 136,889 — Lombard Debt 139,399 — 150,211 — Promissory notes 17,069 — 17,069 — Airnorth Debt 6,624 — 6,778 — Humberside Debt 329 — 329 — $ 644,369 $ — $ 670,022 $ — March 31, 2020 LIABILITIES PK Air Debt $ 207,326 $ — $ 180,290 $ — Macquarie Debt 148,165 — 138,133 — Lombard Debt 136,180 — 122,165 — Term Loan 61,500 — 56,894 — Airnorth Debt 7,618 — 7,221 — Humberside Debt 335 — 335 — $ 561,124 $ — $ 505,038 $ — The carrying value is net of unamortized discount as follows (in thousands): Successor September 30, 2020 March 31, 2020 PK Air Debt $ 11,095 $ 12,620 Macquarie Debt 9,196 11,063 7.750% Senior Notes 6,589 — Lombard Debt 23,817 26,372 Airnorth Debt 339 605 Total unamortized debt discount $ 51,036 $ 50,660

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Fleet — The Company’s unfunded capital commitments as of September 30, 2020 (Successor) consisted primarily of agreements to purchase helicopters and totaled $85.1 million , payable beginning in fiscal year 2021 through fiscal year 2022 . The Company also had $1.3 million of deposits paid on options not yet exercised. All of the Company’s capital commitments (inclusive of deposits paid on options not yet exercised) may be terminated without further liability other than aggregate liquidated damages of $2.1 million . Included in these commitments are orders to purchase three AW189 heavy helicopters and five AW169 light twin helicopters. The AW189 helicopters are scheduled to be delivered in fiscal year 2022 . Delivery dates for the AW169 helicopters have yet to be determined. In addition, the Company had outstanding options to purchase up to ten additional AW189 helicopters. If these options are exercised, the helicopters would be scheduled for delivery in fiscal year 2022 and fiscal year 2023 . The Company may, from time to time, purchase aircraft for which it has no orders. Other Purchase Obligations — As of September 30, 2020 (Successor), the Company had $9.6 million of other purchase obligations representing non-cancelable PBH maintenance commitments. General Litigation and Disputes The Company operates in jurisdictions internationally where it is subject to risks that include government action to obtain additional tax revenue. 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. In addition, from time to time, the Company is involved in tax and other disputes with various government agencies. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its condensed 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.

TAXES

TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
TAXES	TAXES The Company’s effective tax rate was (44.2)% and 11.8% during the three months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor), respectively, and 10.9% and 10.1% during the six months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor), respectively. The effective tax rate in the three and six months ended September 30, 2020 (Successor) includes the impact of utilization of net operating losses in certain foreign jurisdictions and adjustment to its valuation allowances against future realization of deductible business interest expense. The Company’s provision for income taxes for the interim period ended September 30, 2020 was prepared by applying the estimated annual income tax rate for the full fiscal year to income from continuing operations, excluding discrete items, for the reporting period. For the interim period ended June 30, 2020, the Company utilized the discrete effectively tax rate method to report its provision for income taxes. The relationship between the Company’s provision for or benefit from income taxes and the Company’s pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, including asset sales, (b) changes in the blend of income that is taxed based on gross revenues or at high effective tax rates versus pre-tax book income or at low effective tax rates and (c) the Company’s geographical blend of pre-tax book income. Consequently, the Company’s income tax expense or benefit does not change proportionally with the Company’s pre-tax book income or loss. Significant decreases in the Company’s pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The change in the Company’s effective tax rate excluding discrete items for the three and six months ended September 30, 2020 (Successor) compared to the three and six months ended September 30, 2019 (Predecessor) primarily related to changes in the blend of earnings taxed in relatively high taxed jurisdictions versus low taxed jurisdictions and nondeductible professional fees related to the Merger. The six months ended September 30, 2020 (Successor) income taxes include a benefit of $17.0 million related to the bargain purchase gain and an expense of $3.9 million from the impairment of the Company’s investment in Líder. Additionally, the Company increased its valuation allowances by $2.8 million and $3.6 million for the three months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor), respectively, and decreased its valuation allowances by $6.2 million and increased its valuation allowances by $3.3 million for the six months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor), respectively, which also impacted the Company’s effective tax rate. Valuation allowances represent the reduction of the Company’s deferred tax assets. The Company evaluates its deferred tax assets quarterly, which requires significant management judgment to determine the recoverability of these deferred tax assets by assessing whether it is more likely than not that some or all of the deferred tax asset will be realized before expiration. After considering all available positive and negative evidence using a “more likely than not” standard, the Company believes it is appropriate to value against deferred tax assets related to foreign tax credits and certain foreign net operating losses. For the three months ended September 30, 2019 (Predecessor), the Company released valuation allowances of $0.2 million related to net operating losses in certain foreign jurisdictions and deductible business interest expense. For the six months ended September 30, 2020 (Successor) and September 30, 2019 (Predecessor), the Company released valuation allowances of $9.6 million and $7.2 million , respectively, related to net operating losses in certain foreign jurisdictions and deductible business interest expense, respectively. The benefit of an uncertain tax position taken or expected to be taken on an income tax return is recognized in the condensed consolidated financial statements at the largest amount that is more likely than not to be sustained upon examination by the relevant taxing authority. Interest and penalties, if any, related to uncertain tax positions would be recorded in interest expense and other expense, respectively.

Share-based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION AND OTHER EMPLOYEE BENEFIT PLANS	SHARE-BASED COMPENSATION AND OTHER EMPLOYEE BENEFIT PLANS Management Incentive Plan On the Effective Date, the Compensation Committee of Old Bristow’s Board adopted the 2019 Management Incentive Plan (the “MIP”). At the time of its adoption, the MIP served as an equity-based compensation plan for directors, officers and participating employees and other service providers of Old Bristow and its affiliates, pursuant to which Old Bristow was permitted to issue awards covering shares of the Old Bristow Common Stock and Old Bristow Preferred Stock. During the five months ended March 31, 2020 (Successor), Old Bristow awarded 188,210 shares of restricted Old Bristow Preferred Stock, 312,606 shares of restricted Old Bristow Common Stock, 113,081 Old Bristow Preferred Stock options and 265,049 Old Bristow Common Stock options. Upon the closing of the Merger, these awards converted into 656,617 shares of restricted Combined Company Common Stock and 433,283 stock options to purchase Combined Company Common Stock, of which 73,131 shares of restricted Combined Company Common Stock and 48,448 Combined Company Common Stock options vested and 227,884 shares of restricted of Combined Company Common Stock and 151,307 Combined Company Common Stock options forfeited on June 11, 2020 (Successor). Upon the closing of the Merger, 151,768 shares of unvested Combined Company restricted stock awards previously issued under the Era Group Inc. 2012 Share Incentive Plan (the “2012 Incentive Plan”) remained unvested. Total stock based compensation expense, which includes stock options and restricted stock was $2.0 million and $7.2 million for the three and six months ended September 30, 2020 (Successor), respectively. On June 17, 2020 (Successor), the Company awarded 150,001 shares of Combined Company performance restricted stock units at an average grant date fair value of $7.73 and 150,001 stock options to purchase Combined Company Common Stock at a grant date fair value of $10.99 to certain senior executives. The performance restricted stock vests on a cliff-basis after three years based on certain stock price performance targets. The following table shows the assumptions used to compute the stock-based compensation expense for stock options granted on June 17, 2020 (Successor): Common Stock Options Risk free interest rate 0.5 % Expected life (years) 6.5 Volatility 80.0 % Weighted average exercise price of options granted 15.76 Weighted average grant-date fair value of options granted 10.99 During the three months ended September 30, 2020 , the Combined Company awarded 218,088 shares of restricted stock units at an average grant date fair value $19.41 per share and 11,667 stock options at a grant date fair value of $14.56 .

STOCKHOLDERS' INVESTMENT, EARNINGS PER SHARE AND ACCUMULATED OTHER COMPREHENSIVE INCOME	STOCKHOLDERS’ INVESTMENT, EARNINGS PER SHARE AND ACCUMULATED OTHER COMPREHENSIVE INCOME Stockholders’ Investment, Common Stock and Preferred Stock As of September 30, 2020 (Successor), there were 29,813,734 shares of Combined Company Common Stock and no shares of the Combined Company’s preferred stock issued and outstanding. In connection with the Merger, the Old Bristow Preferred Stock which was previously defined, was converted into Old Bristow Common Stock which was previously defined, and then all Old Bristow Common Stock was converted into the Combined Company Common Stock. Because the Old Bristow Preferred Stock could be redeemed in certain circumstances outside of the sole control of Old Bristow (including at the option of the holder), but was not mandatorily redeemable, the Old Bristow Preferred Stock was classified as mezzanine equity and initially recognized at fair value of $618.9 million as of October 31, 2019 (Successor). This amount was reduced by the fair value of the bifurcated derivative liability as of October 31, 2019 (Successor) of $470.3 million , resulting in an initial value of $148.6 million . The difference between (a) the carrying value of the embedded derivative of $270.8 million plus the carrying value of the Preferred Stock Host of $148.6 million and (b) the fair value of the Old Bristow Common Stock of $270.7 million paid as consideration for the Old Bristow Preferred Stock was recognized in retained earnings because the fair value of the Old Bristow Common Stock was less than the combined carrying values of the Old Bristow Preferred Stock host and embedded derivative. Prior to the Merger, there were 11,092,845 shares of Old Bristow Common Stock and 6,725,798 shares of Old Bristow Preferred Stock issued and outstanding. As described in Note 7 to the condensed consolidated financial statements, Old Bristow repurchased certain shares of Old Bristow Common Stock and shares of Old Bristow Preferred Stock immediately prior to the conversion of the Old Bristow Preferred Stock into Old Bristow Common Stock. The repurchase was accounted for in the same manner as the share conversion and included in the calculation described above. The Old Bristow Preferred Stock was converted into Old Bristow Common Stock at a rate of 5.179562 shares of Old Bristow Common Stock for each share of Old Bristow Preferred Stock. The Old Bristow Common Stock was then subsequently exchanged for the Combined Company Common Stock, resulting in a total of 24,195,693 shares of Combined Company Common Stock issued to legacy Old Bristow stockholders. This resulted in a total of 30,882,471 shares of Combined Company Common Stock issued and outstanding immediately after consummation of the Merger. Upon the closing of the Merger, 217,899 shares of restricted stock awards and 145,263 stock options to purchase common stock for certain employees, related to Old Bristow employees, were canceled as a result of separation from the Combined Company. Upon the closing of the Merger, vesting of 145,604 shares of restricted stock awards, related to the Combined Company’s employees were also accelerated. Share Repurchases. On September 16, 2020, the Board authorized a stock repurchase plan providing for the repurchase of up to $75.0 million of the Company's common stock. Repurchases under the program may be made in the open market, including pursuant to a Rule 10b5-1 plan, by block repurchases, in private transactions (including with related parties) or otherwise, from time to time, depending on market conditions. The share repurchase program has no expiration date and may be suspended or discontinued at any time without notice. During the three months ended September 30, 2020 , the Company repurchased 345,327 shares of common stock in open market transactions for gross consideration of $7.6 million , which is an average cost per share of $21.93 . After these repurchases, as of September 30, 2020 , $67.4 million remained of the $75.0 million share repurchase program. Earnings per Share Basic earnings per common share is computed by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share excludes options to purchase common shares and restricted stock units and awards which were outstanding during the period but were anti-dilutive. The following table shows the computation of basic and diluted earnings per share (in thousands, except share and per share amounts): Three Months Ended September 30, Six Months Ended September 30, Successor Predecessor Successor Predecessor 2020 2019 2020 2019 Income (loss): Net income (loss) attributable to Bristow Group Inc. $ (27,861 ) $ (162,974 ) $ 43,616 $ (332,220 ) Less: PIK dividends (1) — — (12,039 ) — Plus: Deemed contribution from conversion of preferred stock — — 144,986 — Income available to common stockholders – basic $ (27,861 ) $ (162,974 ) $ 176,563 $ (332,220 ) Less: Preferred stock adjustments — — (3,377 ) — Income available to common stockholders – diluted $ (27,861 ) $ (162,974 ) $ 173,186 $ (332,220 ) Shares: Weighted average number of common shares outstanding – basic 29,357,959 35,918,916 20,230,285 35,918,916 Net effect of dilutive stock options and restricted stock — — 13,801,372 — Weighted average number of common shares outstanding – diluted (2) (3) 29,357,959 35,918,916 34,031,657 35,918,916 Earnings per common share - basic $ (0.95 ) $ (4.54 ) $ 8.73 $ (9.25 ) Earnings per common share - diluted $ (0.95 ) $ (4.54 ) $ 5.09 $ (9.25 ) ___________________________ (1) See “ Stockholders’ Investment, Common Stock and Preferred Stock ” above for further discussion on PIK dividends.

The Old Bristow Preferred Stock is not included on an if-converted basis under diluted earnings per common share as the conversion of the shares would have been anti-dilutive. (3) Potentially dilutive shares issuable pursuant to the warrant transactions entered into concurrently with the issuance of the Combined Company’s 4½% Convertible Senior Notes (the “Warrant Transactions”) were not included in the computation of diluted income per share for the three six months ended September 30, 2019 , because to do so would have been anti-dilutive.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 interest entities (“VIEs”) of which the Company is the primary beneficiary. All significant inter-company accounts and transactions are eliminated in consolidation.
Current Expected Credit Losses (CECL)	Current Expected Credit Losses (“CECL”)
Guarantors of Securities	Guarantors of Securities In March 2020, the SEC amended Rule 3-10 and 3-16 of Regulation S-X, CFR 210.1-01 through 210.3-16, regarding financial disclosure requirements for debt securities issued in registered offerings involving subsidiaries of the registrant as either issuers or guarantors. This amended rule narrows the circumstances that require separate financial statements or summarized financial disclosures of issuers and subsidiary guarantors and simplifies the summarized disclosures required in lieu of those statements. Under the new rule, comparative period information is no longer required. As a result of this amended rule, the Company has included narrative disclosures in lieu of separate financial statements. The Company has early adopted this new rule and has elected to provide the simplified disclosure related to its 7.750% Senior Notes due 2022 within the MD&A.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s consolidated financial position or results of operations. Adopted In June 2016, the FASB issued ASU No. 2016-13, 2019-04, “Measurement of Credit Losses on Financial Instruments” (ASU No. 2016-13), which sets forth the current expected credit loss model, a new forward-looking impairment model for certain financial instruments based on expected losses rather than incurred losses. The ASU is effective for interim and annual periods beginning after December 15, 2019, and early adoption of the standard was permitted. Entities were required to adopt ASU No. 2016-13 using a modified retrospective approach, subject to certain limited exceptions. Upon evaluating the impact of this ASU, the Company concluded that no additional reserves were necessary as historical losses were immaterial, and, based on the qualitative and quantitative analysis performed in accordance with ASC 326 requirements, the Company determined there was no reasonable expectation of credit losses associated with the Company’s trade receivables in the foreseeable future. ASU No. 2016-13 was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurements” (Topic 820) modifying the disclosure requirements on fair value measurements. The amendment modifies, removes, and adds several disclosure requirements on fair value measurements in ASC 820, Fair Value Measurement. The amendment will be effective for the Company in fiscal year 2022, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020 prospectively, and such adoption did not have a material impact on its condensed consolidated financial statements. In August 2018, the FASB modified ASU No. 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans” (Subtopic 715-20), for changes to disclosure requirements for employers that sponsor defined benefit pension plans. Certain disclosure requirements were removed and certain disclosure requirements were added. The amendment also clarifies disclosure requirements for projected benefit obligations and accumulated benefit obligations in excess of respective plan assets. The amendment is effective beginning in the Company’s fiscal year 2021 financial statements, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020 by removing the weighted-average expected long-term rate of return on assets in this Quarterly Report. Annual disclosure requirements will be reflected in the Annual Report. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software” (Subtopic 350-40), providing guidance that addresses the accounting for implementation costs associated with a hosted service. The guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. The amendment is effective beginning in fiscal year 2021 financial statements, and early adoption is permitted. The guidance will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. This disclosure requirement was adopted effective April 1, 2020 prospectively, and such adoption did not have a material impact on its condensed consolidated financial statements. In October 2018, the FASB amended ASU No. 2018-17, “Targeted Improvements to Related Party Guidance for Variable Interest Entities” (Topic 810), the guidance for determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in generally accepted accounting principles). Therefore, these amendments likely will result in more decision makers not consolidating VIEs. This amendment is effective beginning in the Company’s fiscal year 2021 financial statements, and early adoption is permitted. This disclosure requirement was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-03, “Codification Improvements to Financial Instruments”, which makes improvements to financial instruments guidance. The standard is effective immediately for certain amendments and for fiscal years beginning after December 15, 2019. This accounting guidance was adopted effective April 1, 2020, and such adoption did not have a material impact on the condensed consolidated financial statements. Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes” (Topic 740), new guidance to simplify the accounting for income taxes, which eliminates certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. This ASU also includes guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. The standard will be effective for the Company in fiscal year 2022 and early adoption is permitted. The Company is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, “Investments-Equity Securities” (Topic 321), “Investments-Equity Method and Joint Ventures” Topic 323 and “Derivatives and Hedging” Topic 815 (ASU No. 2020-01) as an update to ASU No. 2016-01 “Financial Instruments-Overall”, further clarifying certain interactions between the guidance to account for certain equity securities under Topic 321, 323 and 815, and improve current GAAP by reducing diversity in practice and increasing comparability of accounting. The standard will be effective for the Company in fiscal year 2022, and early adoption is permitted. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform” (Topic 848). The guidance is intended to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. The standard will be effective for the Company in fiscal year 2022. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, “Debt - Debt with Conversion and Other Options” (Subtopic 470-20) and “Derivatives and Hedging - Contracts in Entity's Own Equity” (Topic 815) as a means of simplifying and reducing the number of accounting models for convertible debt instruments and convertible preferred stock. The ASU also amends the guidance for derivatives scope exception for contracts in an entity's own equity. The goal being to reduce differences in accounting for similar contracts between different companies that are accounted for as derivatives by some and equity by others. The standard will be effective for the Company in fiscal year 2022. The Company has not yet adopted this accounting guidance and is currently evaluating the effect this accounting guidance will have on its consolidated financial statements.
Revenue Recognition	Revenue Recognition The Company derives its revenues primarily from oil and gas flight services and search and rescue services. A majority of the Company’s revenue is generated through two types of contracts: helicopter services and fixed wing services. Revenue is recognized when control of the identified distinct goods or services has been transferred to the customer, the transaction price is determined and allocated to the satisfied performance obligations and the Company has determined that collection has occurred or is probable of occurring. The Company determines revenue recognition by applying the following steps: 1. Identify the contract with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price; 4. Allocate the transaction price to the performance obligations; and 5. Recognize revenue as the performance obligations are satisfied. Operating revenue from the Company’s oil and gas line of service is derived mainly from fixed-term contracts with its customers. Fixed-term contracts typically have original terms of one to five years , subject to provisions permitting early termination by customers. Customers are typically invoiced on a monthly basis with payment terms of 30 - 60 days . The following table shows the total revenue related to third party customers (in thousands): Three Months Ended September 30, Six Months Ended September 30, Successor Predecessor Successor Predecessor 2020 2019 2020 2019 Revenue: Operating revenue from non-affiliates $ 282,060 $ 290,939 $ 528,189 $ 594,672 Operating revenue from affiliates 3,267 5,365 7,861 9,840 Reimbursable revenue from non-affiliates 8,918 13,536 17,603 30,136 Revenue from Contracts with Customers 294,245 309,840 553,653 634,648 Other revenue from non-affiliates 447 409 867 806 Other revenue from affiliates 9,948 7,971 20,313 15,942 Total Revenue $ 304,640 $ 318,220 $ 574,833 $ 651,396 Contract Assets, Liabilities and Receivables The Company generally satisfies performance of contract obligations by providing helicopter and fixed wing services to its customers in exchange for consideration. The timing of performance may differ from the timing of the customer’s payment, which results in the recognition of a contract asset or a contract liability. A contract asset exists when the Company has a contract with a customer for which revenue has been recognized (i.e., services have been performed), but customer payment is contingent on a future event (i.e., satisfaction of additional performance obligations). These contract assets are transferred to receivables when the right to consideration becomes unconditional. Contract liabilities relate to deferred revenue in which advance consideration is received from customers for contracts where revenue is recognized based on future performance of services.
