The two main options are the military or the aviation
oriented colleges. Neither are easy paths.
The military has limited slots and so is sorta hard to
plan on. (but certainly NOT impossible) The advantage
here is the lack of cost, however there is a commitment
to be fulfilled.
The aviation college route is easier to plan on, but it'll
cost to attend. I believe Embry-Riddle (Daytona Beach,
FL) and Purdue (Indiana, I think) are the key, but not only players here.
Either path will be a long road and so one needs to keep sight of the goal fairly strongly in order to be successful.
One thing I would do right away (If you haven't already) is to go out to the airport and take the "Intro
flight" to make sure this is the path you want.
I started taking lessons at 14 yrs old, applying every
grass cutting dollar I could... That was 29 years ago,
and I haven't regretted any of it ever.
