Do not go to university in the vague hope that a degree might impress a future employer. Most especially, do not go and do an 'aviation related' degree in the hope that it might impress an airline - it won't. Especially if you fail that degree because you aren't interested in the subject.
If you harbour an ambition to be an aviation engineer, or if the engineering side of aviation really interests you, then by all means go and do Aeronautical Engineering and enjoy it. Similarly, if the business and operations side of aviation really floats your boat, go and do one of the increasing number of Airline Operations and Commerce type courses. If you have no intention of ever becoming an engineer or an airline accountant or ops controller, why do these courses?
If you really want a degree and flower arranging is your deepest joy, but you want to earn your money flying, go and do a degree in flower arranging and get some flying on the side while you're at Uni (join the UAS). If you've no interest in a degree, don't do one!
However, you should have a backup plan - a way of earning money if flying doesn't work out, or while you're trying to earn the money to learn to fly. Whether it's plumbing or IT, bricklaying or high finance, doesn't matter - get yourself some qualification and experience that will keep the wolf from the door when (and I do mean when) flying won't pay the bills.
