I know a 50 year old guy who just got hired with a regional at 800 total 100 multi and no type ratings or airline experience. He was a business manager and had the flight time and decided to change careers. He worked as a CFI for about six months to get some recent flying experience and was hired quick by the regionals.

I'd say your chances are really good at getting back into it. You're still young enough and on top of that you have 121 experience. A lot of companies will like that. You'd probably get the job over me easy.

A Cessna 172 Heavy? I've gotta get me one of those!
