The 25 Worst Airports in America, From Newark to Dallas (Photos) - The Daily Beast Interesting to see. I've been to 18 of the 25 they list, and in my opinion, they got most of the worst ones, although the omissions of Sky Harbor and SeaTac are glaring. I disagree with Denver being on the list, though. I've always had good experiences there, and they have a ton of amenities if you get tied up there for a while. For me, the worst will always be O'Hare, with Atlanta being a close second, and Dallas at 3rd.
