All international flights at Hartsfield-Jackson Atlanta International Airport (ATL) operate out of the Maynard H. Jackson Jr. International Terminal, which consists of Concourses E and F. If you are being dropped off or checking in for an international departure, you should follow the signs for the "International Terminal" via I-75 Exit 239, which is a completely separate entrance from the Domestic Terminal. In 2026, Concourse F serves as the primary gateway for international check-in and departures, while Concourse E is often used for overflow or international arrivals that require customs clearance. A common mistake for travelers is going to the Domestic Terminal to check in for an international flight; while you can take the "Plane Train" between terminals post-security, the baggage check and ticketing for airlines like Air France, Virgin Atlantic, and Lufthansa are located exclusively at the Maynard Jackson terminal on the airport's east side.
