applicable GAAP outside the Topic (908-10-15-1), and the guidance reaches passenger and cargo carriers, joint operations, and carriers providing ancillary services (maintenance, food service) to others (908-10-15-2; 908-10-05-2). The Overall subtopic (908-10) is essentially scope plus background, then routes the reader to subtopics on Segment Reporting, Inventory, Intangibles—Takeoff and Landing Slots, Property, Plant, and Equipment, Compensation—General, Other Expenses, and Nonmonetary Transactions (the revenue subparagraph 908-10-05-1(f) was superseded by ASU 2014-09, so airline revenue now follows Topic 606). The background explains why airlines are distinctive: an unusual revenue cycle of advance and third-party ticket sales where the sale date rarely matches the service date and tickets may be refundable, exchangeable, or usable on other carriers (908-10-05-3); mobile flight equipment that complicates custody and control (908-10-05-5); carrier-designed, FAA-demonstrated maintenance programs (908-10-05-6); and flight-crew compensation that varies with flying status, equipment, hours, time of day, and seniority (908-10-05-7).
