Sounds like a good trip, although I probably would have spent one night (as I did on a WAS-HNL mileage run a couple of weeks ago), which makes the pain of waving the sun good-bye a bit less.

Of course, some airports -- though ATL is the only one that I can think of off of the top of my head -- have kiosks inside security as well. Or, if you are a member of the Crown Room or other club, you could get a boarding pass there if they have one in your destination.
