Well, you have part of the qualifications, your degree.
Short and simple:
It doesn't matter where you get your training from, just so much as you have the ratings and hours. Look around. I have heard that the average airline new-hire is about 34 years old and has about 5,000 hours total time. However, I know a AA
Eagle new-hire that has about 2,250 hours flying time. He started his training in 1998. Where will you get your hours from?
It also helps if you are rich.
(Or have rich parents who are willing to foot the bill for you!) Flight training is very expensive these days. Back in 1970, it cost me about $18,000 to get to Commercial-Instrument, CFI(I). Nowadays, it'll cost you about $40-60,000! And this doesn't include living expenses such as food, housing, etc. Just when you think you are done, then you need your ATP. And remember that this industry is very cyclical, there are tons of pilots from the airlines still out on furlough.
