You’re making no sense. Why on earth would you join the military (non flying) to get a second bachelors degree using the GI bill to fly? Now is a pretty dang good time to get picked up to be a pilot in the reserves or guard. If you don’t care what you fly or where you live, and can speak somewhat intelligently, have a decent GPA, no criminal record worse than a misdemeanor and speeding tickets, you should be able to get a flying job in the AF. Let Uncle Sam teach you to fly and get you some hours.
Don’t go into more debt for this and don’t join a non flying position and get a second freaking degree...waste of time.
