Expedia is an Internet-based travel website company headquartered in Bellevue, WA, with localized sites for 22 countries. 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 Pegasystems, along with its own hotel reservation system for contracted, bulk-rate reservations. And their latest ad campaign is perfect! With the codes of several airports they’ve created some travel related sentences, the one easier than the other, but overall they’re very, very smart!
