If you find picking up people from the airport a chore (check flight times, calculate when you should leave home etc.), let Just Landed for iPhone help. It’s currently free, well designed and actually works. Unlike a host of other flight tracking apps available for iOS (i.e Flight Track), Just Landed simply tracks inbound flights. Enter the airline code and flight number, and the app will show the landing time, terminal number and approximate driving time based on traffic conditions. And so long as location services is turned on, it’ll even notify you in the background when the the flight has landed and when you should leave for the airport.
