Add Frontier to that list of places that have hired without degrees, the chief pilot I knew got on with them, but it took him a while longer (several years, in my opinion, that is) than if he was able to check the degree box. I wonder what the percentage of nonmilitary, no college degree applicants get hired? Further, I wonder how many didn't have college degrees that were not part of preferential hiring (i.e. white male pilots)? It would make an interesting statistcal analysis.
By the way, did those statistics come from EEOC, Air Inc., FAA or somewhere else? EDIT: (Nevermind, I reread it and saw that you credited Air Inc.) 15% to 22% sounds high to me. I think Air Inc gets their statistics from people sending them data once they are hired, so they don't count every sucessful hire, just the people that bothered to fill out and send in a form. I don't know how scientific that really is.
I've always been told that once you reach competitive flight times, more time really doesn't really help much. At least, that's the advice I had been given through the years. (My favorite advice was from a retired Western Airlines pilot who told me to fake a logbook and go to the airlines; I decided not to take that advice.)
I've based my advice on what I have personally scene in this industry (been working full time about 10 years as a pilot or flight instructor.) I'm sure with your ratings you have been in this industry longer than me though. Still, I'm just giving my opinion based on my experiences.
Last January, I had an a freak accident where I broke up my leg and knee pretty well. For a while they wern't sure if I would be reable to regain my medical again. I was fortunate to have a good doctor and some brand new medical tech they put in my knee, so I only have a very slight limp after all the rehab, and have no problems with my medical. If the worst had happened, I would have been unable to be a pilot, but I still had a degree to fall back on. Without the degree I would not be competive in nonaviation jobs (except asking if the customer wanted fries with that.)
Food for thought for the young man/woman to think about while they are deciding what to do after high school.
