I agree with everything that the guys have just said.
ANd don't be too optomistic about getting a loan either. Banks aren't stupid. THey'll know the state of the industry as well as you do (they'll probably have a more pesimistic point of view actually).
Also consider a back up plan. Suppose you get an ear infection or something in 6 months and can't pass class 1 medical. Then you're stuffed.
Why not go to Leeds uni and do their Airline Management degree ?!
However, the most important thing to remember is never give up on your dreams. Just plan it out carefully.
