A lot of airlines take on apprentices because it "looks Good" , Apprentices are rarley taken on full time.
I would avoid engineering completley and do medicine, that is my advice to you.
Engineering degrees are not worth the paper they are printed on, and everyone wants to be a pilot.
This is from my own experience however i may be wrong, but have seen it first hand.
If you really want to be an engineer join the RAF gain experience earn a crust then step into civi street.
Good Luck
