Would you advise I go to university and study something which I enjoy, or are there degrees which have something to do with aviation.
The way you say it it sounds like aviation and something you enjoy are different things!
I'm sure you don't mean it like that though!
Well, I am starting at Bath Uni doing Aerospace Engineering in September. I'm currently working for a big aerospace company on the Year in Industry.
I would look more closely at both of these things if I were you - (meaning aviation type degrees and the YinI
www.yini.org.uk)
They are both excellent oppourtunities to back-up your flying career should things not turn out how you hope.
I've been self-funding my PPL since I was 16, and am still only 1/2 way through, but would recommend if you haven't already to start putting some hours in your logbook if it's possible for you to do so.
It's not going to be easy, in the current climate at least for you to go straight into flying for a living after A Levels, and although things may have cleared up by the time you reach this stage, there are still going to be plenty of degree level qualified pilots looking for airline work.
As often said, airlines aren't the be all and end all of flying, look at all the routes into commercial operations, talk to people in the know, find out as much about the job as you can (while you still have plenty of free time on your hands - A Levels are still HARD no matter what any newspapers try to say).
First and foremost, don't lose sight of the short term goals - good GCSEs, and A Levels will leave you with many more oppourtunities when you get to 18.
Best of Luck
