Hope my little experience will help any of you!
I suffered from fear of flying since ever... at one point i had to fly Europe (about half a year ago). i got really stressed and hopeless.. started looking for help. at first looked for a fear of flying help seminars nearby, but i couldn't find time to attend one. And I heard about the DVD's, but i really didn't have the patience to sit and watch them... Anyway, in the end, about a week before the flight, a friend told me he heard about an ipad app that might help me. It was few days before the flight and I was quiet anxious already, so I gave it a try.
eventually I chose an app cold Fear of Flying, but I saw on itunes other apps to.
Anyway this app really (!) saved me! my flight went from being a nightmare, into a reasonable experience... it did cost me 10 dollars though but it looked good and serious, so i went for it. it covered allot of topics, and it made me my flight much more comfortable...
Anyway this is from my experience.. and i didn't check other apps so maybe these are good to.. if you want the app i use search the web for - my fear of flying.
