Atlanta is served by Hartsfield-Jackson Atlanta International Airport (ATL), the world's busiest airport by passenger traffic and the primary global hub for Delta Air Lines. This status provides an unparalleled network of domestic arrivals from across the United States and extensive international service from destinations in Europe, Latin America, Asia, and Africa into the city.
The airport receives an immense number of direct flights into ATL. Domestically, it connects from virtually every major and mid-size city in the U.S. to Atlanta. Internationally, key origin destinations include London (LHR), Paris (CDG), Amsterdam (AMS), Tokyo (HND), Seoul (ICN), Mexico City (MEX), São Paulo (GRU), and Lagos (LOS) arriving at ATL.

Delta Air Lines dominates ATL for arrivals, operating the majority of flights into the airport. However, the airport is also a major base for Southwest Airlines arriving in Atlanta and is served by all other major U.S. and international carriers into ATL, including American, United, British Airways, Air France, and Korean Air. This creates intense competition on many inbound routes to Atlanta.
