There are a lot of threads about obtaining a degree - read them, they contain a ton of good advice. This industry is so fickle that down the road you will wish you stuck with school and achieved a four-year degree. If you quit now (after the AS degree) it will be much harder to go back later and finish up those remaining two years. Tough it out, get the four-year and then pursue your career. You can fly while getting your degree to build hours and have some fun, but seriously, stick with school until you have that degree in hand - it only gets harder to go back once you have a job and a few years under your belt.
