We are a global team with representation in the United States, Mexico, Australia and India. Our Flights Shopping Platform is one of the largest in the world serving over 150 million queries a day and powering some of the strongest brands in the industry like Orbitz, Expedia, Travelocity, Wotif, Hotwire and ebookers. Expedia disrupted the airline industry with its flight shopping and booking technology 20 years ago. We always want to “be the place travelers choose to explore and book flights for a trip” and are looking for talent to join us and build technology and experiences that power these. 

What makes Flights technology unique?
