Any piece of concrete at least 13000 feet long, surrounded by plains, no wind, and no higher than 1000ft msl.
But that's not a real answer, of the cities we fly, the real answer is O'Hare. The controllers get the job done, and the runways are long. I could do without the winter w/x, but you can't have everything. I always enjoy the downwind, base and final for 27 when the skies are clear. Nothing like watching the windy city unfold below. Happening on a game at Wrigley is a bonus. BTW, officially I never look at anything outside besides traffic
For cities we don't fly, Austin Bergsrom International. There's live music in the terminal some nights, the terminal food is pretty darned good, the runways are long, taxi times are short, the controllers are decent (not current info), it's not far from the parking lot to my driveway and I pass a lot of good BBQ joints on the way to the barn.
For cities I'd like to fly to, (have but it's been a while), how about LUV? Once again, long pieces of concrete, short taxi's, good food in the area, and a certain airlines HQ!
