Hello! Delta Air Lines operates exclusively out of Terminal South (Terminal S) at Hartsfield-Jackson Atlanta International Airport (ATL) mainly for domestic and makes use of the majority of Concourses A, B, C, D. For international, Delta Airlines ATL Terminal is flown from the Maynard H. Jackson Jr. International Terminal known as Terminal I, with Concourses E and F. Due to the construction, security screening may take longer, and parking may be limited, so it is advisable to arrive at least three hours before departure.
