Same situation, finished my A levels not sure if i should attend university or go straight into aviation training. Having passed my PPL a few months ago i decided to withdraw myself from my university course. Now im going to Oxford School of aviation. However i can only do this because of the financial backing of my parents ( lucky for some eh? ). Also iv'e heard thats british airlines look for EXPERIENCE rather than what degree you have. I know a guy that has a MEng Aerospace Systems Engineering , an ATPL, a job as a flying instructor and less than 1000 hours under his buckle. I guess he's just unlucky but the moral of the story i guess is not to spend money on a degree, when that money could be used getting yourself a commercial license at an early age and begin hour building and experience.
