Remember this; it's not the best pilots who get hired at an airline, it's the persistent and lucky ones. Your lack of a 4yr degree puts you way down in the stack. But don't get discouraged, I personally know of 5 or 6 United pilots who do not have 4yr degrees - so they were very lucky. How lucky do you feel? Why not try and push a little harder and get that 4yr degree - either way, be persistent and don't give up.
