Hartsfield–Jackson Atlanta International Airport (IATA: ATL, ICAO: KATL, FAA LID: ATL), also known as Atlanta Airport, Hartsfield, or Hartsfield–Jackson, is an international airport located 7 miles (11 km) south of Atlanta's central business district, in the U.S. state of Georgia. It is named after former Atlanta mayors William B. Hartsfield and Maynard Jackson. The airport has 209 domestic and international gates. ATL covers 4,700 acres (1,902 ha) of land and has five parallel runways.
The airport has international service within North America and to countries in South America, Central America, Europe, Africa and Asia. As an international gateway to the United States, Hartsfield–Jackson ranks sixth. Many of the nearly one million flights are domestic flights from within the United States, where the airport serves as a major hub for travel throughout the southeastern region of the country.
Atlanta has been the world's busiest airport by passenger traffic since 1998; and by number of landings and take-offs from 2005 to 2013, losing that title to Chicago–O'Hare in 2014, but regaining it a year later. Hartsfield–Jackson held its ranking as the world's busiest airport in 2012, both in passengers and number of flights, by accommodating 100 million passengers (more than 260,000 passengers daily) and 950,119 flights. In 2017, it remained the busiest airport in the world with 104 million passengers.
