From everything I've heard and personally observed, the age concerns are a thing of the past. I thought I would be the old guy in my new hire class at 37 years old, however, I was 10 out of 20, with the oldest guy being 54 or 55 (don't remember). I would say that being under 30 is now the exception rather than the rule and I've seen new FOs at SWA who are in their fifties quite often. You only live once, do what is going to make you happy and leave you with no regrets....just my .02
