Domestic terminal atlanta airport Jackson Hartsfield One of the busiest airports in the world is Atlanta International Airport, or ATL for short. The Domestic Terminal and the International Terminal are the airport's two primary terminals. There are two sides to the Domestic Terminal: North and South. Delta Air Lines is the main user of the North Terminal, using it for the majority of its domestic flights. Other domestic carriers like Southwest, American, and United Airlines use the South Terminal. You must first go through the check-in process to obtain your boarding card and have your bags checked when you arrive at the Domestic Terminal. Arriving early is advised because security screening happens after check-in and can get crowded. You will enter the concourses, designated A through T, after passing through security. Every concourse features a number of gates as well as different facilities including stores, eateries, and restrooms. The Plane Train is a practical subterranean train system that connects the concourses and facilitates speedy passenger movement between them. If you have a connecting flight in a separate concourse, this is quite useful. The Domestic Terminal offers a ground transportation facility with taxis, shuttles, ride-sharing services, and public transportation alternatives available for ground transportation. Additionally, parking facilities are offered, including economical, daily, and hourly parking. All things considered, Atlanta Airport's Domestic Terminal is built to efficiently handle large passenger volumes. It's an efficient facility that makes traveling easy with its clear signage, friendly staff, and range of amenities. Just make sure to check the details of your trip in advance and allow ample time to navigate the congested airport upon arrival.
