Congrats to all of the Firsties on their base assignments! It is so much fun to hear about where everyone is going.
stvblm - Hearty congrats to your son for ENJJPT. Currently there are only 33 slots per year, so he definitely impressed someone.
As far as the question of how UPT start dates are decided: I've been told that it is not a specific formula, but they first try to give as many people their choice of base. This is possible up to a point, since they also try to distribute the OPA/order of merit evenly between the bases. Then they also assign UPT start dates in a way that distributes the OPA throughout each of the UPT classes. You wouldn't want all of the top 20 2Lts in OPA to be assigned to the same UPT class where they would be in competition with each other for the one or two fighter/bomber slots available to their class. That is why it may seem to be a random placing of start dates where someone much higher in OPA gets a start date 6 months after someone who ranked in the bottom 50%.
There are lots of reasons why our son wanted to get assigned to 'Hell Rio" a/k/a Laughlin AFB. It was actually his second choice after Sheppard. One reason is that it has the highest amount of flying days of any of the UPT choices. Very rarely is the weather severe enough to ground the planes. Since our son has been there they have only been grounded a few days due to high winds. That is important when trying to avoid delays in graduation date.
He has also found that the location is really what you make of it. Del Rio has Lake Amistad for boating, fishing, and swimming. There are also 5 large tracts of land both on and off the base that the base hunting club leases for hunting. There are opportunities for white-tail, mule deer and boar. Our son and his roommates have had a lot of fun during casual. Once UPT starts there is very little time to do much so the location becomes even less important according to him.
One thing to be prepared for is changes in their start date. Our son lives with three other USAFA grads for UPT. All four were supposed to be in the same class, but ended up spread throughout three different classes. Once they are about two weeks prior to their start date they are locked in for that class. That is when we finally made hotel reservations to go visit him. We didn't want to have to change them.
