Entities in the airline industry primarily provide carrier services for passengers and cargo, frequently as joint operations. Other services, such as maintenance or food service for other carriers, may also be provided. ##### [908-10-05-3](https://asc.understandingaccounting.org/asc/908/10/#908-10-05-3) Pending content: no Source downloaded (UTC): 2026-09-10T02:08:51.822Z to 2026-09-10T02:08:51.822Z Record version: sha256:be9f4a70d8db9e45ee926459ee6db63911e737dbb7e005d8d0e7c82cdb0d4639 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. The most unusual characteristic of the airline industry is its revenue cycle. Sales may be made at numerous locations by either the carrier or third parties (travel agents or other carriers); for some carriers, third parties handle a substantial portion of the ticket transactions. [Paper tickets](https://asc.understandingaccounting.org/glossary/p/#paper-ticket "A printed document that serves as evidence of payment of the fare for air transportation. It authorizes carriage between the points and via the routing indicated and also shows the passenger's name, class of service, carrier(s), flight number(s), dates of travel, and all conditions of the contract of carriage. Generally, this takes the form of the standard Air Traffic Conference ticket, which is composed of an auditor's coupon, agent's coupon, flight coupon(s), and passenger's coupon. The auditor's coupon is the initial document used to record a sale. Flight coupons represent each flight segment (leg) of the passenger's itinerary. Flight coupons are lifted (detached from the ticket booklet) by the carrier providing the transportation service at the boarding point as evidence of the service rendered, although today this process is entirely electronic for the vast majority of ticket sales and boarding transactions.") and [electronic tickets](https://asc.understandingaccounting.org/glossary/e/#electronic-ticket "An electronic (or e-ticket) reflects the passenger's itinerary in electronic form. Like paper tickets, e-tickets contain information for each flight segment of a passenger's itinerary. However, while a paper ticket consists of multiple coupons that are used to record a sale and to document the service rendered, e-tickets exist only as a digital record in the airline computer system and contain no paper coupons. Instead, the airline's host reservation system or global distribution system (GDS) produces an e-ticket sales record for each sale transaction, which is used to record a sale of e-ticket. Boarding documents are issued for e-tickets at check-in, and the carrier documents transportation service at the boarding point by either collecting boarding documents or scanning them as evidence of the service rendered.") usually are sold in advance of the transportation date, and the ticket sales date usually does not coincide with the revenue recognition date (the date that service is provided). Tickets sold are not necessarily used, in whole or in part, on the carrier making the sale, and some tickets are refundable if not used by the customer for up to one year after the sales date. Other tickets are nonrefundable but exchangeable with payment of a fee, and other tickets are nonrefundable and nonexchangeable. The determination of revenue recognized may be complex. ##### [908-10-05-4](https://asc.understandingaccounting.org/asc/908/10/#908-10-05-4) Pending content: no Source downloaded (UTC): 2026-09-10T02:08:51.822Z to 2026-09-10T02:08:51.822Z Record version: sha256:4820be8d6ffb143df5d881fcb5a1e82fca42d7350a7220f7f2293864ac2becc9 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps.

A major portion of an airline's fixed assets comprises aircraft and other flight equipment. Because such assets are constantly changing locations, the responsibility for physical custody and control of aircraft is substantially different from that of nonmobile fixed assets. ##### [908-10-05-6](https://asc.understandingaccounting.org/asc/908/10/#908-10-05-6) Pending content: no Source downloaded (UTC): 2026-09-10T02:08:51.822Z to 2026-09-10T02:08:51.822Z Record version: sha256:0879c47ede5b8088c0c8f60c17f1e7eef1e16753e3ea18481c3fdd26af91b16d Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Maintenance requirements are dictated by the highly sophisticated nature of the industry's equipment. The timing and extent of maintenance procedures are determined by individual carriers using studies based on actual experience that demonstrate [airworthiness](https://asc.understandingaccounting.org/glossary/a/#airworthiness "The ability of a particular aircraft or component part to perform its function satisfactorily through a range of operations determined by the Federal Aviation Administration.") to the Federal Aviation Administration. Maintenance may be provided in-house, which requires maintenance facilities outfitted with specifically designed equipment. ##### [908-10-05-7](https://asc.understandingaccounting.org/asc/908/10/#908-10-05-7) Pending content: no Source downloaded (UTC): 2026-09-10T02:08:51.822Z to 2026-09-10T02:08:51.822Z Record version: sha256:6ea890a4cd73f1729fac09c8d26272d3dbf73c05462b5d4d91cd228107b166e7 Snapshot version: sha256:15aea8165dff9f5ae47d9484f8470588b13b307f56e1d50801bf4d85ec190e3f Effective as of: not established by retrieval timestamps. Compensation of flight personnel usually represents a significant portion of an airline's operating expenses. The amount of compensation is generally dependent on a number of variables, including, among others, flying status, type of equipment flown, hours flown, whether flights are made during the day or at night, and employee seniority.
