BNA is an interesting choice, as the city has grown by leaps and bounds in the last few years. With all of the automobile assembly plants and associated businesses that have popped up in Middle Tennessee in the last 15 years or so, I would have to say that business travel there is doing well. Of course, a start up there would be toe to toe with Southwest.

I dont remember all of the facts, but it seems to me that AA killed the former TWA operation in St. Louis because it didnt make sense to their ORD and DFW operations.
