I second all the advice so far given, maybe with a bit less slagging off of the FD. A foundation degree isn't what people think of as a 'degree' (BSc, BA, BEng etc) which is a level 6 qualification of some 360 credit points. You can use a foundation degree 'on the way to' a proper, level 6 qualification. It's a pile of points after all.
Do a saleable degree, earn money, go flying.
Oh, and don't think ANY degree (proper one) will help you get into the front of a jet!
