Go For It Wannabe
I'm 37 and a career changer. 15 years ago, getting a job with an airline required F-16 experience, internship at NASA while earning your PhD in astrophysics, 25 lunar orbits and a spacewalk in addition to 10,000 hours turbine PIC.
Seriously though, the time just wasn't right for me until now. I thought I would be the oldest in my class, but was beat by 5 years. There are 3 others in their mid 30's.
It's never too late and I admire you for having the balls to do it. Your age and life experience will be an asset in the cockpit.
