Atlanta's second airport was an idea being studied by the city of Atlanta, Georgia, United States.
In May 2007, the Federal Aviation Administration released the report, "Capacity Needs in the National Airspace System, 2007–2025" as part of its Future Airport Capacity Task (FACT2). The report identified Hartsfield-Jackson Atlanta International Airport and the Atlanta metropolitan area as needing additional capacity by 2025. Following the report release, Atlanta was given a $1 million federal grant to study the possibility of adding another airport.
Both Atlanta and Delta Air Lines, which operates its primary hub there, expressed skepticism about building a second airport because it would be expensive and will likely economically fail, according to Delta.
In 2011, the Atlanta Metropolitan Aviation Capacity Study, Phase II was completed by the FAA, the City of Atlanta and a consulting team. The study concluded that Dobbins Air Reserve Base was the best site from a market potential and development cost perspective, however, the airspace and environmental aspects were problematic. The second best possible site was Cobb County Airport due to its accessibility, yet the high development costs were prohibitive.
In 2014, Hartsfield-Jackson Atlanta International Airport unveiled its 20-year Master Expansion Plan to adequately cover the air travel capacity needs in the Atlanta area through 2035.
An additional commercial airport for the Atlanta metropolitan area could be created by expansion of an existing general aviation airport, conversion of an air force base or by new construction on a greenfield site.
In 1975, in anticipation of a second airport, the City of Atlanta purchased 10,165 acres (41.14 km2) of land west of the city in Paulding County for $925 per acre. In early 2007 Paulding County purchased 162 acres (0.7 km2) of the property for a new general aviation airport (opened in 2009 as Paulding County Regional Airport), however Atlanta's second commercial airport could still be built on the remaining property. Paulding County is unserved by either rapid transit or freeways.
