What are we all harping on about ?
There was a recent graduate from OAA who joined BA at 18 with fATPL.
Also there are several 19 year old's ex OAA and other establishments with fATPL on courses with airlines now. They may be 19 or 20 by the time they finish their line training. But at any age its no mean feat to be flying in the right seat of a modern jet, as it takes hard work and dedication to achieve that goal.
Good luck to this young man.
If he's that exceptional then he should get a job soon, maybe we will hear on the news that he's the youngest ...... etc etc etc.
All credit to those out there of ANY age who achieve their fATPL its no small thing.
Getting high grades or first time examination passes does not matter to some recruiters. The first time passes in the flight checks and 1st series IR are more important.
Finally the individuals personality matters when it come to maturity and "Can I sit next to him for X hours" is a major factor in the individual fitting into their organisation.
Good luck to all out there job hunting, take whatever is offered to you.
Get that foot on the first rung of the ladder, whatever the aircraft type.
