Hello,
I agree with Lucifers post earlier on also WX Man. Firstly, you won't even get your degree if you choose it
purely because you think it'll help you out as a pilot. SO choose something you want to do cause its bloody hard anyway.
Secondly, personally I wouldn't bother with an aviation related one. One of my friends who is an instructor started Aero Eng but dropped out in the second year just because he didn't enjoy it.
Try and choose a multipurpose degree. I'm in my second year of Law which I reckon is one of the best fallbacks to have.
Happy flying,
