Delta Airlines operates a significant portion of its flights from Hartsfield-Jackson Atlanta International Airport (ATL), making Atlanta an important destination and connection point for travelers. Delta passengers can access airline check-in and ticketing facilities in the Domestic Terminal, while flights may depart from different concourses throughout the airport. Because ATL is a large airport, passengers should check their boarding pass and airport information displays for the latest concourse and gate assignment. Travelers can also find baggage services, security checkpoints, dining areas, retail stores, transportation options, and other passenger facilities throughout the airport. Whether you are starting your trip in Atlanta or connecting to another Delta flight, understanding the airport layout can make your journey easier.
