See what that means for your trip: seven concourses, two terminals and one train. Updated November 15, 2026 ![Hartsfield-Jackson airport seen through an airliner window on approach, with long parallel concourses and runways laid out among suburbs, highways and trees.](https://atlairportguide.com/images/atl/concourse-a-window-apron-v22.webp) Atlanta airport from the air on approach ATL says it’s the world’s busiest airport, and its own fact sheet puts the average at 286,000 passengers a day. The same sheet says ATL has held the title in 23 of the 24 years it counts, and it doesn’t say when it last updated that count. The title is ATL’s own claim: its pages name no ranking body and print no other airport’s total. Plan around the layout instead, starting with the concourses. ## What ATL’s fact sheet gives | Measure | ATL’s figure | | --- | --- | | Passengers a day | 286,000 on average | | Arrivals and departures a day | 2,100 on average | | Gates | 155 domestic and 43 international | | Distance from downtown Atlanta | 10 miles | ATL’s maps page puts the drive from downtown at about 20 minutes south in normal traffic. The fact sheet gives no date for its averages. ## How “busiest” is counted ATL’s news item on its nineteenth straight title says ATL had more aircraft operations than any other US airport. It adds that ATL was “likely” ahead worldwide, pending final tallies from international airports. ## Seven concourses ATL’s tips for travelers name the seven concourses as T, A, B, C, D, E and F. They also warn that it’s easy to confuse terminals with concourses, so confirm your concourse and gate after you check in. If you can’t find yours, Customer Experience Representatives give directions at the Domestic Terminal’s west crossover and in the Transportation Mall at the Plane Train, and our [information desks page](https://atlairportguide.com/amenities/information-desks/) lists the Customer Experience Representatives. Concourse T adjoins the Domestic Terminal, and Concourse F adjoins the International Terminal. Concourses A through E are separate buildings out on the airfield, linked by the Plane Train, though ATL’s fact sheet groups Concourse E with the International Terminal and Concourse F. Our [terminals page](https://atlairportguide.com/terminals/terminal/) lists every concourse and its gates. Our [airlines page](https://atlairportguide.com/airlines/) shows where each airline checks in and departs. Our [flights page](https://atlairportguide.com/flights/) links to each airline’s own page, and it doesn’t show live gates. ## The Plane Train ATL’s fact sheet describes the Plane Train as underground and says it connects all concourses with the Domestic and International Terminals. It adds that trains run about every two minutes. ATL’s Plane Train story calls it automated. ATL’s tips call it the fastest way through the airport and say it runs through the Transportation Mall. ATL’s holiday tips say that if you have extra time, skipping the train for the moving sidewalks lets children peek at art exhibits. The same page suggests an art walk for a long wait, with Flight Paths between Concourses A and B. None of these pages gives a walking time between concourses. ## Two terminals Alaska, American, Avelo, Delta, Denver Air Connection, Frontier, JetBlue, Southwest, Sun Country and United check in at the Domestic Terminal. Delta also checks in on the International Terminal’s departures level. The International Terminal has its own entrance, separate from the Domestic Terminal. ATL’s maps page says you reach it from I-75 at Exit 239. A free [International Terminal shuttle](https://atlairportguide.com/transport/international-terminal-shuttle/) leaves the curb outside the International Terminal and drops passengers at the west end of the Domestic Terminal. The fact sheet puts that ride at 15 minutes and says it runs 24 hours a day. ## Does busiest mean long lines? Not always. One commenter on a plane-spotting video of ATL called the airport super busy but said the security line took under 10 minutes, adding that you have to know the right time to travel and get there early. ATL says the busiest times at security usually fall between 5 a.m. and 9 a.m. It asks you to arrive two hours before a domestic flight and three before an international one. It also says passengers can reach all concourses and gates from any checkpoint. CLEAR lists these lanes: - Domestic Terminal North, which ATL calls the Lower North checkpoint: a Plus standard lane, 4:30 a.m. to 7:30 p.m. - South Checkpoint, Domestic Terminal: a Plus TSA PreCheck lane, 4:30 a.m. to 9 p.m. - International Main Checkpoint: Plus standard and TSA PreCheck lanes, 5 a.m. to 7:30 p.m. Our [security page](https://atlairportguide.com/security/) lists every checkpoint with its published hours. ### Sources - Our [terminals page](https://atlairportguide.com/terminals/terminal/), [airlines page](https://atlairportguide.com/airlines/), [information desks page](https://atlairportguide.com/amenities/information-desks/), [International Terminal shuttle page](https://atlairportguide.com/transport/international-terminal-shuttle/) and [security page](https://atlairportguide.com/security/) - ATL’s fact sheet - ATL’s news item on its nineteenth consecutive title - ATL’s tips for navigating the airport - ATL’s Plane Train story - ATL’s holiday travel tips - ATL’s terminal maps and directions page - ATL’s passenger security page - A comment on Razgriz Flight & Spotting’s plane-spotting video of ATL
