Mobile App: Check your flight status
FlightTrack Pro gives you a flight's departure time, current speed, altitude, location, and odds for an on-time arrival. Most important, you can share flight information with your friends via Twitter, Facebook, or e-mail, which is useful if someone's coming to pick you up at the airport. Just enter an airline and flight number, choose by route, or simply sync the service with your TripIt itineraries (see above), and Flight Track will send you the latest updates, including gate status and delays.
Cost: $4.99; $9.99 for the Pro version, which adds more real-time information.
Runs On: Android, BlackBerry, iPad, iPhone/iPod Touch.
