It’s worth knowing that the ATPL framework for higher educational qualifications is on par with Diploma level study. Lots of Universities allow entry onto the 3rd year of a BSc Aviation Management course if you have an ATPL. You essentially top up your ATPL with one further year of study and get a BSc. Many integrated flying schools offer this option now but you can also do it independently as a qualified pilot, there are lots of airline pilots doing this one year top up, fitting in the study around flying schedule and hours in the cruise.
If you can find training for another job that you can always fall back on when the aviation industry dips then I’d recommend doing that. Financially the tuition fees for 2 yrs of University study are saved and can be spent in a PPL/CPL. Good luck which ever route you choose.
