Hartsfield–Jackson Atlanta International Airport (ATL): America’s Busiest Airport
Hartsfield–Jackson Atlanta International Airport (IATA: ATL), located in Atlanta, Georgia, is one of the most important transportation hubs in the United States and the world. Commonly referred to simply as "Atlanta Airport," ATL has consistently ranked as the world’s busiest airport in terms of passenger numbers and number of takeoffs and landings.
Serving as a major connection point for domestic and international travel, ATL is the primary hub for Delta Air Lines and offers nonstop service to over 150 U.S. destinations and more than 75 international destinations across six continents.
History of Atlanta Airport
Atlanta’s aviation history began in 1925 when a five-year lease was signed on an abandoned auto racetrack, known as Candler Field. This field would soon become Atlanta Municipal Airport. The first commercial flight landed in September 1926, and by the 1930s, it had become one of the busiest airports in the United States.
During World War II, the airport played a key role in military aviation, and after the war, commercial air traffic boomed. The airport was renamed several times: in 1946 it became Atlanta Municipal Airport, in 1971 it was renamed William B. Hartsfield Atlanta International Airport, and in 2003, the name was expanded to honor former Atlanta Mayor Maynard Jackson, becoming Hartsfield–Jackson Atlanta International Airport.
With continued expansion, ATL grew to become a global leader in aviation, setting records in both domestic and international travel.
Terminals and Layout
ATL operates with a unique and efficient layout that includes two terminals—Domestic Terminal and Maynard H. Jackson Jr. International Terminal—and seven parallel concourses (T, A, B, C, D, E, F) connected by the Plane Train automated people mover.
- Domestic Terminal: Divided into North and South sides, primarily serving domestic airlines including Southwest and Delta.
- International Terminal (Concourse F): Serves all international arrivals and departures, equipped with customs and immigration facilities.
Thanks to this linear concourse design and efficient train system, passengers can move between gates quickly, even during peak hours.
