Hartsfield–Jackson Atlanta International Airport

Hartsfield–Jackson Atlanta International Airport known as Atlanta Airport, Hartsfield, or Hartsfield–Jackson, is the primary international airport serving Atlanta, Georgia. The airport is located seven miles south of the Downtown Atlanta district, it is named after former Atlanta mayors William B. Maynard Jackson; the airport has 192 gates: 40 international. ATL has five parallel runways. Hartsfield–Jackson is the primary hub of Delta Air Lines, is a focus city for low-cost carriers Frontier Airlines and Southwest Airlines. With just over 1,000 flights a day to 225 domestic and international destinations, the Delta hub is the world's largest airline hub. In addition to hosting Delta's corporate headquarters, Hartsfield–Jackson is the home of Delta's Technical Operations Center, the airline's primary maintenance and overhaul arm; the airport has international service within North America and to South America, Central America, Europe and Asia. As an international gateway to the United States, Hartsfield–Jackson ranks seventh in international passenger traffic.

Many of the nearly one million annual flights are domestic flights. Atlanta has been the world's busiest airport by passenger traffic since 1998; the airport is in unincorporated areas of Fulton and Clayton counties, but it spills into the city limits of Atlanta, College Park, Hapeville. The airport's domestic terminal is served by MARTA's Red and Gold rail lines. Hartsfield–Jackson began with a five-year, rent-free lease on 287 acres, an abandoned auto racetrack named The Atlanta Speedway; the lease was signed on April 16, 1925, by Mayor Walter Sims, who committed the city to develop it into an airfield. As part of the agreement, the property was renamed Candler Field after its former owner, Coca-Cola tycoon and former Atlanta mayor Asa Candler; the first flight into Candler Field was September 15, 1926, a Florida Airways mail plane flying from Jacksonville, Florida. In May 1928, Pitcairn Aviation began service followed in June 1930 by Delta Air Service; those two airlines, now known as Eastern Air Lines and Delta Air Lines would both use Atlanta as their chief hubs.

The airport's weather station became the official location for Atlanta's weather observations September 1, 1928, records by the National Weather Service. It was a busy airport from its inception and at the end of 1930 it was third behind New York City and Chicago for regular daily flights with sixteen arriving and departing. Candler Field's first control tower opened March 1939; the March 1939 Official Aviation Guide shows fourteen weekday airline departures: ten Eastern and four Delta. In October 1940, the U. S. government declared it a military airfield and the United States Army Air Forces operated Atlanta Army Airfield jointly with Candler Field. The Air Force used the airport to service many types of transient combat aircraft. During World War II the airport doubled in size and set a record of 1,700 takeoffs and landings in a single day, making it the nation's busiest in terms of flight operation. Atlanta Army Airfield closed after the war. In 1942 Candler Field was renamed Atlanta Municipal Airport and by 1948, more than one million passengers passed through a war surplus hangar that served as a terminal building.

Delta and Eastern had extensive networks from ATL, though Atlanta had no nonstop flights beyond Texas, St. Louis, Chicago until 1961. Southern Airways appeared at ATL after the war and had short-haul routes around the Southeast until 1979. In 1957 Atlanta saw its first jet airliner: a prototype Sud Aviation Caravelle, touring the country arrived from Washington D. C; the first scheduled turbine airliners were Capital Viscounts in June 1956. The first trans-Atlantic flight was the Delta/Pan Am interchange DC-8 to Europe via Washington starting in 1964. Nonstops to Europe started in 1978 and to Asia in 1992–93. Atlanta claimed to be the country's busiest airport, with more than two million passengers passing through in 1957 and, between noon and 2 p.m. each day, it became the world's busiest airport. Chicago Midway had 414 weekday departures, including 48 between 12:00 and 2:00 PM. In 1957, Atlanta was the country's ninth-busiest airline airport by flight count and about the same by passenger count.

That year work began on a $21 million terminal which opened May 3, 1961. It could handle over six million travelers a year. In March 1962 the longest runway was 7,860 feet. In 1971 the airport was named William B. Hartsfield Atlanta Airport after former Atlanta mayor William B. Hartsfield, who had died that year; the name change took effect on February 28. That year the name became William B. Hartsfield Atlanta International Airport; the airport's terminal until the 1970s was on the north side of the airport. Six pier concourses radiated from a central building. Construction began on the present midfield terminal in January 1977 under the administration of Mayor Maynard Jackson, it was the largest construction project in the Sou
