If you're at all geeky like me, you might wonder if you ever have flown on a specific aircraft before. The easiest way to know this is to track the Tail Number of planes you fly.

I just released (for free) an iOS app that allows you to easily record key flight details and the tail number of your plane. The app keep tracks of all this and alerts you when you enter a new plane tail if you've ever flown on that physical plane before - and if so, on which routes and dates.

I'd love any feedback or suggestions for future features. You can learn more and download it for free at http://www.PlaneTailTracker.com
