Chris,
Here you go: Am I too old to be an Airline pilot?
It’s important that you’re realistic about your goals. Chances are you won’t be a wide body Capt at a Major. Narrow body? Maybe and in reality you may not want to. You could have a very nice career as a senior Capt at a Regional. While the money’s def better at the Majors you’d be starting again at the bottom of a very long seniority list and that’s if you ever get the offer.
