Travel technology
Travel agencies use the services of the major computer reservations systems, also known as global distribution systems (GDS), including: Amadeus CRS, Galileo GDS, Sabre, and Worldspan, which is a subsidiary of Travelport, which allow for comparison and sorting of hotel and flight rates with multiple companies. Bookings made via travel agents, including online travel agents, may or may not be confirmed instantly. Unlike online travel agencies, metasearch engines and scraper sites, such as Skyscanner, Kayak.com, Rome2rio, and TripAdvisor, travel agencies may or may not have their own booking engine, and instead provide results for search queries and then divert traffic to service providers or online travel agencies for booking. Travel agents may also work with airline consolidators.
