While I agree that military flying is not opnly demanding it, is a calling. Lets not sit here and say that most of us are have not thought about flying in the airlines someday after the Air Force flying is over with. I think that part of the problems that we pilots face is not thinking down the road in future and planning our lives out alittle better. With that said I would go around telling people that the only reason you joined the military was to get to airlines. But make wise choices about your career if thats what you want to do. ie. dont suck in training.
You may want to look at life styles of each a/c that you decide to. Each a/c has unique lifestyles with unique people. Pick the ones you get along with the most. Sometimes personalities dont mesh.
