Yes I've been to ATL before and each time I was in and out like clockwork. I know it can get backed up, especially in the summer. When I said its not at capacity, I didn't mean they could stand to add another 100 flights per day. But the question of int'l expansion to Asia came up which would at the most be half a dozen flights maybe over several years time. Oh and Im from New York so seeing JFK completely choked off every day is "at capacity" in my eyes. ATL does very well with its 5 runways and end-around taxiway to keep things moving.
