The app tracks just about everything you can think of regarding specific flights. Once you’ve found a specific flight, you can access the arrival and departure times, delay forecasts, alternate flights, and even seat maps. Should you need to make a not about the flight, that’s an option as well. The app shows you an actual physical map, showing your literal flight track across the country. You can zoom in and see every single city and road you’ll be flying over in great detail. The app is very customizable and generally well put together. It’s a bit pricey if you aren’t a frequent flier, but it’s definitely a worthwhile app.

The FlightTrack app offers flight information for approximately 16,000 airports worldwide and about 1,400 airlines. That’s a lot of flights in the sky! The detailed flight maps on this app are absolutely beautiful. When you open the app, you can shake your smartphone to track a random flight. It’s a great way to tour the world for free! You don’t even have to get on a plane. I can see this feature of the app entertaining inquisitive children and even grown-up kids for hours at a time. Using the app is straightforward. Just add one or more planes to track by inputting their flight number or route. Basic flight information appears, along with status updates, weather information related to both the incoming and outgoing airport and any pertinent delays.

FlightTrack really shines when you tap the Map tab. Overlay satellite imagery from Google Maps will display each plane’s current position and flight path. The menu allows you to refresh all the data instantly, and even post the information to your Facebook Wall or Twitter stream. Now everyone in your family can see when grandma and grandpa are getting into town for the holidays! Plus, you can add a widget to your home screen to see real-time flight data without launching the app.

The app also makes is easy to find alternate routes and flights if you’re having difficulties. This can save time at the airport as you’re waiting in line to rebook a flight because of bad weather or other circumstances. This feature alone makes the $4.99 price tag look absolutely tiny compared with its usefulness.

So next time you are waiting for a loved one to arrive on a delayed flight, pull out the FlightTrack app and go on a free flight around the world while you wait.
