About 4 years ago me and a Buddie of mine the same age both wanted to be pilots, He went through college first (spent 4 years at it and just graduated) and he is now working as a lineman at a FBO saving every penny working for his ratings. I went through ATP, had all my ratings in a year then flight instructed about a year, built up 1400 hours, then got a corporate job making around 50 K and totally debt free. Been doing college online on the side, and got 1.5 years to go yet. by the time I get my degree, I should have around 2000 hours, and I already got a decent job.
I was happy to do my ratings first, I think it helped me catch up a little since I had a later start. to the guys that did college first, more power to them, I don't think myself, I could have waited that long to fly for hire.
Note: ATP is a good program, however because of their outrageous price increases, I would recommend a different accelerated flight school other then ATP
