I just turned 27 and I'm looking at alternate career paths. I'm considering ATC, but I'm not sure if I'm getting too old. I know there is some sort of age 30 cut-off; but I'm not sure exactly what that entails.
So am I too old? By the time I completed a 2yr ATC degree, I'd be 29.5

.
So do I have to get hired before 30 or how does that work?
Thanks for the input!
