Why not ask your son what he wants to do for a living, rather than 'steer' him in the direction of a flying career?
Forget the dedication to professional standards that the job requires, if he doesn't really want those wings then he won't even get through the hours of ground study, exams, and pre-flight preparation that he needs even to get his frist commercial licence!
Personal motivation is absolutely essential in achieving the standards required of even a 'junior First Officer' on a commuter line (some of whom are quite happy and have no desire to become a 'Senior long haul Captain').
BTW which airlines do you think are 'quality' enough for you to be satisifed with your son's achievements in the future?
You don't say how old your son is, but assuming he is at least 17 or so, why not buy him a trial lesson (and make it apparent it is JUST FOR FUN!!!) - if he has what it takes to become a successful commercial pilot he'll do the rest himself without any 'steering' required!
And if he then does want it bad enough, the money won't be important, nor will working for a 'quality' airline.
I wish him all my very best, sounds like he's going to need it.
