If your non military it will only help level the playing field. Im going to go back in the fall for an Aviation Safety Masters at University of Central Missouri. Its all online and one of the cheapest courses around. While a masters doesn't guarantee you a job or get you one it helps separate you from the rest of the crowd. And if it gets you hired a couple months earlier at a major it'll pay for itself. Also a good idea to diversify but personally I don't have the patience or the money to take pre requisites for another masters.
