摘要:Commercial airlines began using computerized reservation system (CRS) technology in the mid-1970's, t These systems consist of mainframe computers and assorted peripherals operated by the airlines, telecommunications equipment connecting the airlines '2 computers with the travel agents, and a plethora of terminals and printers in the offices of user travel agents. -~ CRS technology works as follows: The proprietary airline installs the system for the travel agency and lists its flight schedules on the system so that the travel agents can peruse the listings and select the most appropriate flights for customers. The travel agents can then use the interactive aspects of the system to reserve flights for customers and to print tickets on ticket stock provided by the airline. This is substantially more efficient than the previous method of telephoning various airlines, requesting flight information, relaying that information to the customer, and then requesting tickets.
