Hartsfield-Jackson Atlanta International Airport ATLKATL

ATL is one of the most important connecting airports in the United States and Delta Air Lines’ home mega-hub, making it especially strong for SkyTeam connections. It is primarily a domestic transfer machine, but it also has a broad international network across Europe, Latin America, the Caribbean, Africa, the Middle East and Asia. Southwest and Frontier also have meaningful operations here, though the airport experience is most Delta-centric. For frequent flyers, ATL’s strength is predictable airside connectivity: all concourses are linked behind security by the Plane Train and a pedestrian tunnel. The main friction points are landside: Domestic and International terminals sit at opposite ends, MARTA rail is at the Domestic Terminal, and international arrivals or self-transfers need more buffer.
