Don`t do it !!
After 30 years as a Licensed Engineer I can safely say there are much better ways to earn a living, the pay is, at best no more than average (especially considering the responsibilities),the hours will be long and unsociable, and the managements are always looking for someone to blame for their shortcomings.
Use the degree for something that makes you feel valued as the professional you are ( not a sentiment you will get from airline owners).
Call me old and cynical, but honestly, most longer serving licensed engs will agree
