# The airline hub

Every ATL guide on the airline hub: 4 guides, each answering one question. They include connecting through ATL on Delta: how it works.

Updated November 15, 2026

How ATL works for the airline that runs its hub here: where it checks in, which concourses it flies from, how its connections move between them and what to do when one goes wrong. Each guide answers one question about flying that airline through ATL.

Delta Help Desks sit in five ATL concourses and the Plane Train waits under two minutes. See Delta's desks, Sky Club hours and what's unpublished.

Delta help desks sit on Concourses A, B, C, E and F. Delta says rebook in the app or at a kiosk, and ask an airport agent about hotel and meal vouchers.
