None of them are profitable (for you at least)... each one is presumably a course that you must take as part of a curriculum to graduate a pilot program.

Each lists a course of training to get all of the necessary experience and FAA ratings to earn the "privilege" of being a commercial pilot.

But if this is really a serious question, I'd suggest that you do some more research before jumping into this industry... It's probably not everything you expect it to be. If it's flamebait, then so be it... hope you're having fun... but you'll have better luck here: www.flightinfo.com
