Initiating your travel day with the airport’s largest hub operator means heading straight to the Delta AirLines ATL Terminal. The carrier sets up its primary landside operations inside the Domestic South building, featuring distinct check-in lines tailored for premium Sky Priority flyers, international connections, and standard main cabin passengers. After finalizing your digital check-in and handing off your heavy luggage, you can step right into the adjacent security lines to enter the departure concourses.
