Operations, Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition In general, we recognize revenue when it is both realized or realizable and earned. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement, generally a client contract exists; the services or products have been performed or delivered to the client; the sales price is fixed or determinable; and collection is probable. More specifically, revenue from helicopter services is recognized based on contractual rates as the related services are performed. The charges under these contracts are generally based on a two-tier rate structure consisting of a daily or monthly fixed fee plus additional fees for each hour flown. These contracts are for varying periods and generally permit the client to cancel the contract before the end of the term. We also provide services to clients on an “ad hoc” basis, which usually entails a shorter contract notice period and duration. The charges for ad hoc services are based on an hourly rate or a daily or monthly fixed fee plus additional fees for each hour flown. In order to offset potential increases in operating costs, our long-term contracts may provide for periodic increases in the contractual rates charged for our services. We recognize the impact of these rate increases when the criteria outlined above have been met. This generally includes written recognition from our clients that they are in agreement with the amount of the rate escalation. Cost reimbursements from clients are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our condensed consolidated statements of income. Bristow Academy, our helicopter training business unit, primarily earns revenue from military training, flight training provided to individual students and ground school courses. We recognize revenue from these sources using the same revenue recognition principles described above as services are provided. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement, generally a contract exists; the services have been performed or delivered to the client or student; the sales price is fixed and determinable; and collection has occurred or is probable. Eastern Airways International Limited (“Eastern Airways”) primarily earns revenue through charter and scheduled airline services and provision of airport services. Both chartered and scheduled revenue is recognized net of passenger taxes and discounts. Revenue is recognized at the earlier of the period in which the service is provided or the period in which the right to travel expires, which is determined by the terms and conditions of the ticket. Ticket sales are recorded within deferred revenue until recognized as revenue in accordance with the above policy. Airport services revenue is recognized when earned.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
