About as long as it takes to sign an agreement anywhere else in the country. I have no idea how A-pool is these days, but when I was there, we had plenty of time to do random stuff like house hunting and moving in to a place. If you are a pilot, and you don't have specific orders in hand to Whiting right now, I would err on the side of caution and either find friends to room with, or maybe someone who is already in schools command. I moved to Corpus about 9 weeks after I arrived for the first time in pcola, so I basically never unpacked, crashed in an empty room in some NROTC buds' house, and slept on an air mattress.
