Our E Travel System uses the Sabre Global Distribution System as an integral part of the overall travel system. The GDS is a legacy data based system that is used by all travel suppliers such as airlines, hotels and rental car vendors to automatically book travel. The GDS is separate from the commercial internet booking sites, although some booking sites will use GDS information to offer information to their users and to assist with bookings.
Not all airlines and hotels use a Global Distribution System as the GDS charges travel vendors to display inventories. If a supplier uses a GDS, it is the airline carrier, hotel, or rental car company’s responsibility to keep the GDS updated with current information. In some instances some small airlines do not use the GDS and therefore, the TMC must be contacted directly either by phone or by requesting assistance on line by entering a comment. The TMC will then contact the Non-GDS vendor to work with the traveler to make their reservations.
With domestic and foreign (non-complex) travel it is a requirement that our customers use the online booking tool within our eTS to book their reservations. However with complex foreign travel we encourage our customers to book directly through the TMC via phone. With complex foreign travel, the TMC has knowledge of and can offer advice about Visa requirements, the fly America Act, or if foreign carriers and flights are limited or unavailable in the GDS and will require TMC assistance.
