A uni degree isnt a requirnment on most courses that i know off.
Ive just been accepted on a training course following a tough selection process and having a degree def helped in my interview espically as it is an aerospace engineering degree.
Also the airlines love guys with some " life experience" so it gave me plently to talk about with regard to teamwork and setbacks etc. But if you got those things covered with other aspects with your life you should be ok
hope this helps
