Corporate Aviation
I flew for about 10 years as a corporate stew in Los Angeles. You can try Jet Aviation or TAG. Netjets would be a good place to start out. There were rumors (from women) that they didn't hire guys, thereby protecting their territory. Proved them wrong., haha.. You really have to get in there and meet someone. They usually run very secret operations. Good luck and drop me a line if you want to know more.
