As he is only 15 I suggest he joins the air cadets and gets some free gliding experience then in a couple of years completes the PPL.The industry would have hopefully improved in 3 years time and then I would suggest an ab-initio approved course to complete his ATPL. It works out expensive but better to spend the money on this rather wasting 30K at university where the degree isn't worth the paper it's written on and little of chance of getting a job relevant to the qualification.
