If you fly frequently and have an iPhone, you might have already researched the iTunes App Store for titles that will help you track your flight, pick your seat, and check for delays. As a frequent flier and airline geek, I've browsed quite a few apps on the CNET iPhone and have downloaded more than my share. The selection is quite extensive, but as is true with much of the iTunes App Store, it can take time to separate quality apps from those that aren't even worth a free download.
In the slideshow below, I've chosen 10 apps that deserve a look. In addition to helping you accomplish the above tasks, you can use them to find your way through a new airport, track your airline miles, and even listen to air traffic control. After you've perused the list, be sure to tell me about your own picks.
