Sabre is an innovative American company focusing on technological solutions for the airline industry. In the past, it was mainly focused on a reservation system, but it has been branching out into other solutions, such as their travel itinerary app TripCase. TripCase allows users to save their travel itineraries in the app by either forwarding the tickets or looking up the information by reservation numbers. The app then displays relevant information to the trip, such as gate or time changes, local weather reports, opportunities to gain extra miles by using particular car rental companies or hotels, alternative flight options, social media sharing buttons and so on. The app is often praised for its speedy updates and smooth, intuitive interface without obnoxious advertisements.
