To those thinking of skipping uni to start ATPL's I would say think very carefully.
Yes you may have a CPL at 19. Fantastic. But are you employable ? What life skills do you have that would make you a good pilot ? None.
Dont forget that flying is as much a management job (of the aeroplane, crew & pax as it is raw flying these days).
Think what your C.V. will say..... flying, flying and flying. Great, but all flying and nothing else makes John a dull boy.
Go to uni, enjoy yourself, and learn something useful that you can use elsewhere in life, or in between flying jobs.
Me ? I did my ATPL's and FI rating in a year off before uni, did a non flying degree, and graduated with just short of 2000 hours, an honours degree, memories of 3 great years and walked into a jet job. I wouldnt do it any different if I did it all again.
Good luck in whatever you choose.
ps And another thought, if you go to uni, youll still have 35 years of commercial flying left, more than enough to do everything and get bored several times over ! Theres no rush, remember you only live once !
