This is predominantly a European forum, you are best asking over at some place like flightinfo.com .
Apart from that I can confess to being a high school drop out, owned a flight school and air charter business for a while ( then I woke up and saw the light and sold it off asap ), then spent some years travelling the world as a flight and ground instructor ,and now fly corporate out of Chicago, and having a nice easy lifestyle . ( I have done 9 duty days this month! )
Keep up the dreams though, I wish you a lot of luck, its a hard business to be in , and from personal experience another word of advice is successful airlines are best run by people with MBA's, not pilots with a passion, so consider which side of the fence you want to sit on before giving up on high school.
