United Airlines ATL Terminal +1–888–839–0502 Hi! The self-service machines at United Airlines ATL Terminal were a breeze to work with, and before we knew it, we had our boarding passes. But if you're the type who doesn't mind talking to an agent, don't worry—the United personnel at the check-in desk were very friendly and efficient. They attended to our bags and ensured everything was processed without any hiccups.
