I used to know someone who flew 747s for BA and I think BA you had to quit at 55, but also someone here flying for Frontier who at 65 had to stop with passengers in the back.
Ok a long time to go but seems a difficult age to get a US Flying job. I have seen Pilots look to go the EB2 NIW, I could see that maybe working if you were at the top of the game for your Airline.
