I apologise for my bad english & poor-to-medium written communication skills, what I ment to say is:
A) Intercockpit is decent quality school, your son will loose nothing by enrolling in it. IC will prepare him very well for future airline career.
B) With today's pilot salaries don't expect your son to be able to pay back amount spent on training anytime soon. 5 yrs grace period would be nice.
Hope this helps
