Hartsfield–Jackson Atlanta International Airport is the primary commercial airport serving the city of Atlanta, Georgia, in the United States. It is identified by the IATA code ATL, the ICAO code KATL and the FAA location identifier ATL. Operated by the City of Atlanta Department of Aviation, the field functions as a public gateway and as a public airport for a broad region of the southeastern United States, handling a very large volume of connecting and origin/destination traffic.

Overview and layout

The airport occupies a large, mostly contiguous site at the southern edge of Atlanta and is organized around a central domestic terminal complex, several concourses, and a separate international terminal with immigration and customs facilities. The facility includes numerous taxiways and parallel runways configured to maximize throughput. The terminal complex supports an automated people mover known locally as the Plane Train, extensive roadways for drop-off and pickup, and a consolidated rental-car facility. The complex includes nearly 200 gates, serving both domestic and international operations.

History and development

The airport began as a municipal airfield in the early 20th century and grew alongside the city. It was later named for two civic leaders, William B. Hartsfield and Maynard Jackson, in recognition of their roles in expanding Atlanta's air connections and infrastructure. Over many decades the airport added terminals, concourses and parallel runways; major renovation projects in the late 20th and early 21st centuries modernized passenger facilities and increased international handling capacity.

Operations, traffic and airlines

Hartsfield–Jackson has repeatedly been cited as the world's busiest airport by passenger numbers and by aircraft movements in the 21st century. It serves tens of millions of passengers annually—historically near the high tens of millions—and processed roughly 89 million passengers in periods of peak activity. The field is the principal hub for Delta Air Lines and was historically the main hub for AirTran Airways. Delta’s presence, concentrated operations and connecting schedules establish the airport as a major airline hub, often described among the largest airline hubs in the world by scheduled flights and connections.

Facilities and passenger services

  • Terminals: a central domestic terminal with multiple concourses plus a dedicated international terminal with passport control and customs processing.
  • Runways and movement: multiple long, parallel runways arranged to allow high rates of arrivals and departures and to minimize delays during peak periods.
  • Passenger amenities: a wide mix of retail, dining, airline lounges, baggage services and ground transportation options designed to serve both origin/destination and connecting travelers.
  • Support facilities: cargo handling centers, aircraft maintenance areas and extensive ground handling operations that support both passenger and freight services.

Ground transport and access

The airport connects to the city and region via a multi-level roadway system, public transit links, regional rail and shuttle services, and an on-site consolidated rental car facility. Ground transportation planning focuses on efficient transfers between terminals and onward travel by private vehicle, taxi, ride-hailing services and public transit.

Economic and regional importance

The airport is a significant economic engine for Atlanta and the wider region. Its role as a connecting hub enables many business and leisure itineraries, supports airline and airport employment, and facilitates trade through air freight. The concentration of scheduled connections at the hub creates high levels of passenger transfer activity and broad nonstop connectivity to domestic and overseas destinations.

Planning, operations and future outlook

Airport planners emphasize operational resilience, efficient passenger flows and periodic infrastructure renewal. Investments have focused on concourse modernization, improved security screening capacity, runway maintenance and enhanced passenger amenities. Continued coordination with airlines and local authorities aims to maintain punctuality, support growth in international routes and adapt to changing travel demand.
