It sounds like he thinks he knows what he's doing but in reality doesn't fully understand what he's getting himself into.
Does he have any flying experience? Most people on integrated courses of the nature he is thinking of already have substantial experience with air cadets, university air squadron et al. Some even hold Private Pilots Licences before they even enrol on the courses.
If he can't back his ideas up to you with some solid and objective experience, how will he ever do it in an airline interview?
