All of my friends that went into the AF went straight from High School. That's not to say that is the better choice. This obviously requires some digging on google! I'll look around and get back to you.
EDIT:
Copy + Paste from Google search:
I'm currently enrolled in my second year of AFROTC, and I can tell you straight up the that you are gonna want to get your degree in what the Air Force calls a "Technical Degree". The reason I say this is, because they are moving more towards selecting people with these degrees. The technical degrees I am talking about are as follows:
* Aeronautical Engineering - 4AYY
* Aerospace Engineering - 4BYY
* Architectural Engineering - 4DYY
* Architecture - 2CAY
* Astronautical Engineering - 4EYY
* Chemistry - 8CYY
* Civil Engineering - 4HYY
* Computer Engineering - 4WYY
* Computer Science - 0CYY
* Electrical Engineering - 4IYY
* Environmental Engineering - 4HEY
* Mathematics - 6YYY
* Mechanical Engineering - 4MYY
* Meteorology/Atmospheric Sciences - 8FYY
* Operations Research - 0YEY
* Physics - 8HYY
So if you see any degree in here that you like, I would suggest you going for it. I'll warn you though that these degrees are challenging, so be prepared to work for it. I am currently pursuing a Mechanical Engineer degree, and I'm not gonna lie its tough. Also, make sure you like the degree, because you will most likely be stuck with it. It is very hard to change majors from a tech to a non tech later on in the program! Don't be afraid to pick another major though. I am just saying that you will have a BETTER chance with one of these degrees. No bias here!!
