Airport History
Hartsfield–Jackson Atlanta International Airport began operations in 1926 as Candler Field, originally serving as a small airfield for the city of Atlanta. Over time, the airport expanded alongside the growth of commercial aviation in the United States, becoming an increasingly important regional airport.
During the mid-20th century, the airport underwent significant development, including the construction of new runways and terminal facilities. It was renamed in honor of former Atlanta mayors William B. Hartsfield and Maynard Jackson, both of whom played key roles in its expansion.
A major milestone came in 1980 with the opening of a new terminal complex, which was one of the largest airport terminals in the world at the time. Continued expansion, including the addition of new concourses and runways, allowed the airport to handle rapidly increasing passenger numbers.
Today, Atlanta Airport’s layout and infrastructure reflect decades of continuous growth and modernization. Its current form supports its role as one of the world’s busiest airports, with a highly efficient system designed to manage large volumes of passengers and aircraft movements.
