I wouldn't worry about your age......When I was doing interviews/hiring for a large regional (during my UAL furlough) we liked to see some "older" folks in the mix... they bring some things to the table that work well in a new hire class... your background in running a small business etc.... I am helping a 52 year old as we speak. A few years ago I helped a 45 year old a few years ago....he is now a senior VP of Flight Ops at a large Jet 121 operator!
Go for it....!
