Looking at retirement data, smart money would say that you would still be on the front of the wave. I got hired at Delta in 2008, and while we haven't hired much since then, big picture, I feel like I was in the very front of a large hiring wave to come. It helps to be young vs. middle age having that prospective though, since the career is longer.
Who knows though. Lots of things can happen, but things "appear" pretty good for anyone hired in the next few years.
