Atlanta's Hartsfield-Jackson International Airport (ATL) is one of the busiest airports in the world, serving millions of passengers every year. For travelers flying with AIR Canada, knowing which terminal they need to navigate to is crucial for a smooth and stress-free journey. Terminal Overview ATL has two terminals: Terminal South and Terminal North. Each terminal is further divided into concourses, making a total of seven concourses throughout the airport. Terminal South Terminal South is the older of the two terminals and is home to Concourses T, A, and B. AIR Canada operates out of Terminal South, specifically from Concourse T. Terminal North Terminal North is the newer terminal and houses Concourses C, D, E, and F. If you find yourself in Terminal North, you are in the wrong place if your flight is with AIR Canada.
