As many have posted here before, good idea to major in something other than aviation so you have some sort of a backup in the event you are furloughed or lose your medical. As for specific courses, business, economics, math (not calculus), physics. Maybe a minor in science, it will be useful if you know fluids and electrons behave. Also some classical physics, since what we do has much to do with conservation and redirection of energy.
