Here's a little more information about the MGIB for you....
Who is Eligible?
You may be an eligible veteran if you have an Honorable Discharge, AND you have a High School Diploma or GED or in some cases 12 hours of college credit, AND you meet the requirements of one of the categories below:
CATEGORY I
* Entered active duty for the first time after June 30, 1985
* Had military pay reduced by $100 a month for first 12 months
* Continuously served for 3 years, OR 2 years if that is what you first enlisted for, OR 2 years if you entered the Selected Reserve within a year of leaving active duty and served 4 years ("2 by 4" Program)
CATEGORY II
* Entered active duty before January 1, 1977
* Served at least 1 day between 10/19/84 and 6/30/85, and stayed on active duty through 6/30/88, (or 6/30/87 if you entered the Selected Reserve within 1 year of leaving active duty and served 4 years)
* On 12/31/89, you had entitlement left from Vietnam-Era GI Bill
CATEGORY III
* Not eligible for MGIB under Category I or II
* On active duty on 9/30/90 AND separated involuntarily after 2/2/91,
* OR involuntarily separated on or after 11/30/93,
* OR voluntarily separated under either the Voluntary Separation Incentive (VSI) or Special Separation Benefit (SSB) program
* Before separation, you had military pay reduced by $1200
CATEGORY IV
* On active duty on 10/9/96 AND you had money remaining in a VEAP account on that date AND you elected MGIB by 10/9/97
* OR entered full-time National Guard duty under title 32, USC, between 7/1/85, and 11/28/89 AND you elected MGIB during the period 10/9/96, through 7/8/97
* Had military pay reduced by $100 a month for 12 months or made a $1200 lump-sum contribution
So kinda like what L0nGb0w said, you won't be able to use your MGIB until you have met the above criteria which means after you are discharged from Active Duty not just after you're done with your training. If you're looking to finish your flight instruction, what you need to do is go and talk to a Tuition Assistance officer when you get to your first duty station. I don't know how the Army does it but I do remember that part of our check-in list with the Marine Corps is to go buy the Education Building and check in with someone there. When you're there you can ask them all sorts of questions about Tuition Assistance and if they cover flight training. All branches offer some sort of Tuition Assistance which covers a few courses each semester. Good luck to you and I hope it all works out.
