TripIt recently sent out a press release to announce that their services and travel features are now offered in more than 300 applications.  Titles such as FlightTrack Pro, TripDeck, TravelTracker Pro, and USA TODAY AutoPilot utilize the TripIt API which provides flight tracking, mobile boarding passes, and other travel tools. Some of the more recent apps taking advantage of the API include Memolane, Planely, and TripCarbon. While not all of these apps are running on Android (yet) they do show us what is capable when companies play nice with each other and share tools. Oh, and we’d be remiss if we didn’t tell you that TripIt also offers their own application for Android as well.
