As long as you have a green card, you have a chance. I got hired with United with no college degree even though 95 percent do have a degree. Hawaiian, American, JetBlue, Spirit and Atlas all hire without degrees even though it's a small percentage. I got hired with United from Qatar Airways, although I'm an American. If I were you, I would stay in Europe because airlines in the U.S suck. There is no real pension and the pay is poor if you factor in income tax.
