An Atlanta airport layover can be straightforward if you understand ATL’s terminal layout before leaving your gate. The airport has a domestic terminal, an international terminal, and Concourses T and A–F, connected by the Plane Train. Your best plan depends on the time between flights, your departure concourse, lounge eligibility, and whether you need to clear immigration or recheck bags.

Important correction

Know the concourses before you navigate

ATL does not have a Concourse G. The passenger layout includes Concourse T and Concourses A, B, C, D, E, and F. The Centurion Lounge is in Concourse E, beside Gate E11—not Concourse F. Concourse F is part of the international terminal complex.

Use the official ATL maps and wayfinding tool for current directions, gates, amenities, and terminal information.

Airport Layout

How is Atlanta Airport organized?

ATL’s domestic terminal and international terminal are connected to the concourse system, but your check-in and baggage arrangements still matter. Most connecting passengers who remain airside can use the Plane Train to travel between concourses without exiting security. Passengers who need to leave the secure area, collect baggage, clear immigration, or change terminals should allow more time.

ATL terminal and concourse overview
AreaWhat to knowLayover planning tip
Domestic TerminalCheck-in, baggage claim, ground transportation, and MARTA station access.Confirm whether your next flight departs from the domestic side and whether you must re-clear security.
Concourse TConnected to the domestic terminal and the Plane Train system.Check your gate rather than assuming all domestic flights use the same concourse.
Concourses A–DMultiple gates, restaurants, shops, and Delta Sky Club locations.Choose food or a lounge close to your gate when the connection is short.
Concourse EIncludes the Centurion Lounge near Gate E11 and a Delta Sky Club near Gate E15.Check eligibility and opening hours before making a lounge detour.
Concourse F / International TerminalInternational departures and arrivals use the international terminal complex; exact procedures depend on the itinerary.For international arrivals, account for immigration, customs, baggage, and any required recheck or security screening.

Official navigation: ATL terminal maps and wayfinding and Delta Sky Club locations. Airline assignments and facilities can change, so verify your gate and lounge location on the day of travel.

Short Connection

Under 2 hours: prioritize your next flight

With less than two hours between flights, your first task is to confirm the next gate and boarding time. The Plane Train can make cross-concourse connections easier, but it does not remove the time needed to walk to a station, wait for a train, find a lounge, queue at reception, and return to the gate.

  • Check your airline app or departure screens for gate changes and boarding time.
  • Stay airside if your itinerary allows it; avoid leaving the airport for a city visit.
  • Choose a meal, restroom, or lounge close to your route rather than crossing the airport for a marginal upgrade.
  • Only visit a lounge if you meet its access rules and can comfortably return before boarding.
Do not use a fixed “90-minute rule.” A 90-minute connection can be tight if your inbound flight is delayed, your gates are far apart, or you must complete additional arrival procedures. Your boarding time and actual itinerary matter more than a generic threshold.
Medium Layover

2–4 hours: food, lounges, and low-risk activities

A two-to-four-hour layover is usually better suited to an airport meal, shopping, a quiet work session, or a lounge visit than a trip downtown. Start by checking the next gate and allow a buffer to return to it.

Centurion Lounge: Concourse E

The Centurion Lounge is post-security in Concourse E, beside Gate E11. American Express currently lists daily hours of 6 a.m. to 11 p.m., but entry is subject to eligibility and space availability. Check the official listing before setting out.

Delta Sky Clubs

Delta lists multiple ATL Sky Club locations, including Concourse T, two locations in Concourse A, and locations in Concourses B, C, D, E, and F. Locations, operating hours, renovations, access policies, and crowding may change.

Check Delta’s current Sky Club directory →

If you do not have lounge access

Use the restaurants, cafés, shops, seating areas, and airport amenities near your gate. Do not assume a Priority Pass membership guarantees access to every lounge or restaurant at ATL; participating locations and entry conditions can change.

See our Atlanta Airport lounge guide and ATL food guide for more options.

Longer Layover

Longer than 4 hours: should you leave the airport?

A longer layover may make a brief city visit possible, but the total time between flights is not the same as free time. Before leaving ATL, work backward from the next flight’s boarding time and account for every step of the return journey.

  • Immigration and customs: International arrivals may need to clear U.S. entry procedures and collect or recheck baggage, depending on the itinerary.
  • Terminal location: MARTA is accessed from the domestic terminal. If you are at the international terminal, use the airport’s official directions to plan the transfer.
  • Transport variability: Include the walk to the station, train wait, ride, destination walk, return journey, and any delays.
  • Security and boarding: Allow enough time to return, clear security if required, and reach your gate before boarding closes.
  • Entry requirements: Confirm that you are permitted to enter the United States and leave the airport if you are connecting internationally.
Practical rule

Do not decide based on a four-hour or five-hour threshold alone. If missing the onward flight would be costly, your entry process is uncertain, or the transport buffer is small, staying inside the airport is the safer choice.

Ground Transportation

Taking MARTA from ATL to downtown Atlanta

MARTA rail serves the airport from a station connected to the domestic terminal. It can be a practical way to reach downtown or Midtown during a sufficiently long stop, but do not treat the train ride as the entire door-to-door journey.

MARTA planning basics
Airport stationConnected to the domestic terminal’s ground transportation area.
FareCheck MARTA’s current fare and payment guidance before travel; fare products and payment systems can change.
Travel timeDepends on your destination, service, waiting time, and walking. Check the current MARTA trip planner for your exact route.
International terminalDo not assume the rail station is directly inside the international terminal. Check ATL’s directions for the current shuttle or transfer route.

Before leaving, confirm the train service, destination station, return service, and any planned service changes. The official MARTA site is the source for current fares and service information.

Airport Amenities

Useful amenities during an ATL layover

Layover Decision Guide

What is the best plan for your layover length?

Use this as a starting point, not a guarantee
Time between flightsUsually sensibleUse caution with
Under 2 hoursGo to the next gate, grab food nearby, use restrooms.Cross-airport lounge detours or leaving security.
2–4 hoursMeal, shopping, work, or a lounge close to your route.Downtown trips and long queues for lounge entry.
4–6 hoursConsider a city visit only after checking entry, transport, and return buffers.Assuming a four-hour layover automatically allows time downtown.
6+ hoursEvaluate a short city visit or a more relaxed airport stay.Immigration delays, baggage recheck, traffic, service changes, and boarding cutoffs.

These are planning scenarios, not airport or airline guarantees. A delayed arrival, separate tickets, international entry requirements, checked baggage, or a distant gate can change what is realistic.

Check the airline app and airport screens for your next gate and boarding time.

2

Check entry and baggage

Confirm whether you must clear immigration, collect bags, recheck luggage, or pass security again.

FAQ

Atlanta Airport layover FAQs

How do I get between concourses at Atlanta Airport?

The free Plane Train connects ATL’s concourses airside. Follow airport signs and check the official map for your route. Walking, waiting, and train time vary, so do not rely on a fixed door-to-door estimate.

Where is the Centurion Lounge at ATL?

The Centurion Lounge is post-security in Concourse E, beside Gate E11. American Express currently lists hours of 6 a.m. to 11 p.m. daily, but access is subject to eligibility and space availability. Confirm current information before visiting.

Does Atlanta Airport have a Concourse G?

No. ATL’s passenger concourses are T and A through F. Check the airport’s official terminal map for current layout and wayfinding.

Can I leave Atlanta Airport during a four-hour layover?

It may be possible for some itineraries, but four hours does not guarantee enough time for a city visit. Consider immigration, baggage, terminal transfers, train waiting time, return security, and boarding. Staying at the airport is the safer choice when these steps leave little buffer.

How do I get from ATL to downtown Atlanta?

MARTA rail serves the airport from the station connected to the domestic terminal. Check MARTA’s current route, fare, schedule, and service updates, and allow time for walking and waiting beyond the train ride itself.

Are there Delta Sky Clubs at Atlanta Airport?

Yes. Delta lists multiple Sky Club locations at ATL, including locations in Concourses T and A–F. Access rules, hours, and facility availability can change; consult Delta’s current Sky Club directory.

Is a lounge visit worth it during a short connection?

Only if you meet the lounge’s access rules and have enough time to visit and return to your gate without jeopardizing boarding. Check the next gate first and avoid a long detour when your connection is tight.

What should international passengers check during an ATL layover?

Confirm whether you need to clear U.S. immigration and customs, collect and recheck baggage, transfer between terminals, or pass security again. Requirements depend on your itinerary, airline, destination, and entry status.
