Clear Signage: ATL’s intuitive signage and straightforward layout simplify navigation, even for first-time visitors.

Understanding ATL’s Layout

Hartsfield-Jackson Atlanta International Airport is designed with a functional, fishbone-shaped layout. The Domestic Terminal serves as the “head,” the International Terminal as the “tail,” and seven airside concourses (T, A, B, C, D, E, and F) form the “ribs.” These are connected by an underground spine known as the Plane Train, which ensures quick and efficient movement across the airport.

The airport consists of:

Domestic Terminal: Divided into Domestic Terminal North and Domestic Terminal South, with separate check-in and baggage claim areas for different airlines.
International Terminal: Located on the eastern side, primarily serving international flights, with check-in, security, and customs facilities.
Seven Concourses: Concourses T, A, B, C, D, E, and F house gates, shops, restaurants, and lounges, accessible post-security.

Passengers with a valid boarding pass can pass through security at either terminal, regardless of their flight’s departure point, provided their airline offers check-in facilities at the chosen terminal. For those with checked luggage, confirm check-in options, while carry-on travelers can check in online and use a printed or mobile boarding pass for flexibility.

Ground Transportation Options (Landside)

Pre-Security Shuttle Service

For passengers needing to travel between the Domestic and International Terminals without passing through security, ATL provides a convenient shuttle service:

From Domestic Terminal: Exit baggage claim via doors W1 or W2 and follow signs to ground transportation. The shuttle departs from this area.
From International Terminal: Pick up the shuttle at the arrivals level, outside doors A1 or A2.
Travel Time: The journey takes approximately 12 minutes, making it a reliable option for landside transfers.
Operating Hours: The shuttle runs frequently, ensuring minimal wait times.

This service is ideal for passengers arriving via the MARTA station (located at the Domestic Terminal) or those needing to transfer terminals for check-in or baggage claim.

Airside Transportation Options

Once past security, passengers have two primary options for moving between concourses and terminals: the Plane Train and walking via the pedestrian mall.

The Plane Train

The Plane Train is the fastest and most efficient way to navigate ATL’s airside areas:

Location: Found on level 0, accessible via escalators or elevators from each concourse or terminal.
Route: Operates on a 3-mile loop, connecting the Domestic Terminal (baggage claim area) to Concourse F (International Terminal), with stops at Concourses T, A, B, C, D, and E.
Frequency: Runs 24/7, departing every 2 minutes.
Accessibility: Features little to no gap between the train and platform, with elevators and escalators at each stop. Wheelchair assistance is available upon request at security checkpoints.
Navigation Aids: Countdown timers, onboard announcements, and maps help passengers plan their route.

The Plane Train is the go-to option for quick transfers, especially for those with tight connections or limited mobility.

Pedestrian Mall

For those who prefer walking or want to explore the airport, the underground pedestrian mall offers an alternative:

Location: Situated on level 0, parallel to the Plane Train.
Features: Equipped with moving sidewalks to speed up travel and adorned with art and history exhibits, making the journey visually engaging.

Walking Times:

Each concourse is approximately half a mile long, with entry points in the middle.
Walking between adjacent concourses (e.g., T to A or A to B) takes about 5 minutes.
A full walk from Concourse A to Concourse F takes around 35 minutes.
Concourse E to F takes approximately 10 minutes.

Accessibility: The mall is fully accessible, with moving walkways and elevators at key points.

Walking is a great option for passengers with extra time or those who enjoy stretching their legs while admiring ATL’s unique exhibits.

Electronic Carts

For passengers with mobility issues, electronic carts are available within concourses to assist with gate-to-gate travel. These are particularly helpful as individual concourses lack moving walkways, and walking to the furthest gates can take several minutes.
