Since airline reservation systems are business critical applications, and they are functionally quite complex, the operation of an in-house airline reservation system is relatively expensive. Prior to deregulation [clarification needed], airlines owned their own reservation systems with travel agents subscribing to them. Today, the GDS are run ...
The departure control system (DCS) is the system used by airlines and airports to check-in a passenger. The DCS is connected to the reservation system enabling it to check who has a valid reservation on a flight. The DCS is used to enter information required by customs or border security agencies and to issue the boarding document.
The Standard Schedules Information Manual (SSIM) published by the International Air Transport Association documents international airline standards and procedures for exchanging airline schedules and data on aircraft types, airports and terminals, and time zones. [1] SSIM is a file format that heavily compresses schedule information.
Programmed Airline Reservations System (PARS) is an IBM proprietary large scale airline reservation application, a computer reservations system, executing under the control of IBM Airline Control Program (ACP) (and later its successor, Transaction Processing Facility (TPF)). Its international version was known as IPARS. [1]
The name of the travel reservation system is an abbreviation for "Semi-automated Business Research Environment", and was originally styled in all-capital letters as SABRE. [1] It was developed to automate the way American Airlines booked reservations.
Their idea of an automated airline reservation system (ARS) resulted in a 1959 venture known as the Semi-Automatic Business Research Environment (SABRE), launched the following year. [8] By the time the network was completed in December 1964, it was the largest civil data processing system in the world. Other airlines established their own systems.
An airline ticket is a document or electronic record, issued by an airline or a travel agency, that confirms that an individual is entitled to a seat on a flight on an aircraft. The airline ticket may be one of two types: a paper ticket , which comprises coupons or vouchers; and an electronic ticket (commonly referred to as an e-ticket ).
Furthermore, online check-in for a flight is often available earlier than its in-person counterpart. [4] The process then transfers to passengers' control over their check-in. Airlines may use the system because self-service is frequently more efficient to operate, with a greater ability to cope with surges in passenger numbers.
