Delta Air Lines is the major carrier headquartered in Atlanta, Georgia. Their global headquarters is located right next to Hartsfield-Jackson Atlanta International Airport (ATL), which serves as their primary and largest hub. Delta moved its headquarters from Monroe, Louisiana, to Atlanta in 1941 and has since grown to become one of the world's largest airlines. In 2026, Delta continues to dominate the Atlanta airport, operating over 70% of the flights there and employing more than 30,000 people in the metropolitan area alone. This relationship has made ATL the busiest airport in the world for passenger service, as Delta's "hub-and-spoke" system funnels millions of travelers through Georgia's capital every year to connect to over 300 destinations worldwide.
