An online travel booking system for airline tickets, hotels, car rentals, cruises and various other attractions and services.
Expedia is an online travel-booking system. It books airline tickets, hotel reservations, car rentals, cruises, vacation packages and various attractions and services via the World Wide Web and telephone travel agents. The site uses multiple global distribution systems like Amadeus or the Sabre reservation systems for flights and for hotels, Worldspan and Pegasus, along with its own hotel reservation system for contracted, bulk-rate reservations. This last is shared with other Expedia, Inc. sites.
