If you own an iPhone, you might be interested in the TravelTracker App ($19.99) that stores information about your flight, hotel reservation, car rental and appointments. It can also provide current flight status, find Amtrak stations and show a plane’s seating chart. Of special interest for frequent flyers, it can track your frequent flyer miles. And travelers using TripIt.com, an online travel organization tool, can download their stored information to TravelTracker.
