Depending on the flow of the UPT pipeline, you can get to UPT in a few short months or up to a yr later after graduating/commissioning
You will be an AD member on casual status assigned to a base until your report date for UPT.
You do not incur any extra time commitment until your graduate UPT.
UPT is @ 1 yr.
Currently, I believe it is an 8 yr commitment.
So let's now put each piece together.
Commissioned
May 2011
Report to UPT
Mar 2012
Graduate UPT
Feb 2013
Add 8 yrs and you are at 2021.
People tend to think when they enter that if I go to UPT I owe 8 yrs from AFA graduation, when the reality is that is not the truth. You owe 8 yrs from getting your wings which could be closer to 10 yrs.
Plus the AF can change the commitment anytime they choose. I recall back in the early 90's it was 7 for one yr group, 9 for the next and 8 the yr after that. The 9 yr group was not allowed to re-negotiate to 8.
