I would call the VA if I were you, and get exact details about both the Chapter 30(Montgomery GI Bill) and chapter 33(Post 9/11 GI Bill) Chapter 30 is the program that offer 60% reimbursement, and chapter 33 will pay for everything as long as it's a part of your degree plan.

So the way I understand it is, chapter 30 will put you about $20,000 in debt at ATP and chapter 33 will actually pay for everything and give you E-5 BAH while your in school, but you have to ensure two things about chapter 33: one the VA approves the school, and two the school offers in-state tuition for vets(because there is a cap on how much per credit hour the VA will pay per state), I know University of North Dakota was going to start in 2009, but I haven't checked back to confirm. I'm not suggesting you go to UND, but to give you idea of where to look. The only bad thing is that it has to be apart of your degree plan in order for the VA to cover the cost, so you may have to major in Aviation or minor in it. Also consider you have 36 months of entitlement, and I would use them all if I were you. 36 months = about 9 semesters of benefit FYI.

I'm currently using chapter 33, wishing my school had an aviation department, but I'll still have 14 months left to use once I'm done.

Good luck!
