I'll be 26/25 when I graduate from my major, would it then be too late if I go to aviation college?

True, but I don't want to be surrounded by 18 year olds, I mean, I hated 18 year olds even when I was 18....let alone when i'm 25/26

I would hope if you're trying to fly a plane you are above the influences of 18 year olds. If that is what is holding you back then don't bother. I'm sure flying will offer more challenges than seeing fresh high school graduates.

@Cross34: Not influence? Just that I don't like hanging with people much younger than me, I prefer older people

Then you should work at a retirement home. I'm just saying the other students should not be a factor in your decision.
