Personally... I think it's a waste of time.
You would be better off getting a full time/part time job and doing your training modular.
- You are going to do 6 years of RAF (maybe more)
- 2-3 Years of flight training
- Another year or so waiting for your first airline job (maybe less)
So basically...You have just wasted 9-10 years of your life trying to use a career path which isn't really benefiting you as well as you think it is.
Think what 9-10 years of flying in civi street could do for your career??
The selection process is hard, and if you don't have the self motivation that you WANT to be in the RAF you wont make it, especially if you are only using it as a spring board into another profession.
(not an airline pilot, just my opinion)
