A degree is a poor backup, and those management courses aren't much use until you've substantial flying experience and are moving into airline management, or you're giving up on flying as a career (and your soul can handle staying in aviation). Get some immediately saleable skills. Right now an HGV licence seems like a good choice, although if I had to go that way, I think I'd train as a chef, simply because I'd enjoy it. The debt you'll run up on practical courses like those will be vastly less than a degree course.
