This is purely speculation, but I think at this point in time, IAD would be much quicker to hold than IAH. Maybe even right out of training... but like OJ said, it's basically wherever they need you at the time you finish training. IAD is one of our most junior bases (the lines suck.. a lot.) Where do you live in Florida? I know MCO would be an easy one leg commute out of IAD... but if you live in a non-hub town in FL, one of the other more "southern" bases might work too.. for example, CHO, which would allow you to connect to FL via CLT or ATL.
