Theyre probably bonded to a J31 thereafter for something ridiculous like 5 years.
If an airline offers you an opportunity like that, a full sponsorship in return for a couple of years of your time then, to me, that is a fantastic deal!
I had to finish uni+work for a couple of years, then take a massive loan to get where I am and would gladly swap my debt for a five year commitment to an airline, especially one that offered a real education in flying!
