About Hartsfield-Jackson Atlanta International Airport
Airport Code and Location
Hartsfield-Jackson Atlanta International Airport, commonly known by its airport code ATL, is located about 10 miles south of downtown Atlanta, Georgia. It’s easily accessible from the city center by car, rideshare, or public transit.
Why Atlanta Airport Is So Busy
ATL’s reputation as one of the busiest airports globally comes down to two main factors: it serves as the largest hub for Delta Air Lines, and its central geographic location makes it a natural connecting point for flights across the U.S. and internationally. This combination results in an enormous volume of both origin/destination travelers and passengers simply passing through on a layover.
Atlanta Airport Terminal Layout Explained
Domestic Terminal (Concourses T, A, B, C, D, E)
ATL’s domestic terminal is organized into concourses labeled alphabetically: T, A, B, C, D, and E. Concourse T is closest to the main terminal, with concourses extending outward in alphabetical order. Understanding this layout in advance can make navigating gate changes or connections significantly less stressful.
International Terminal (Concourse F)
International flights operate primarily out of Concourse F, which includes its own customs and immigration processing area. If you’re connecting from an international flight to a domestic one (or vice versa), it’s important to factor in extra time for this process.
How to Get Between Concourses (The Plane Train)
ATL operates an underground train system often referred to as the “Plane Train” or ATL Skytrain — that connects all concourses, including the international terminal. This is generally the fastest and most reliable way to move between concourses, especially during a tight connection, rather than trying to walk long terminal distances.
How to Navigate a Layover at Atlanta Airport
To navigate a layover at Atlanta Airport: check your connecting gate immediately upon deplaning, use the Plane Train to move between concourses efficiently, allow at least 45–60 minutes for domestic connections, and budget extra time if traveling through the international terminal (Concourse F) due to potential customs processing.
Minimum Recommended Connection Times
While specific minimum connection times can vary by airline and ticket type, general guidance includes:
- Domestic-to-domestic connections: allow at least 45–60 minutes when possible, especially if concourses are far apart
- International connections: budget significantly more time due to customs and immigration processing, particularly if arriving from Concourse F
- Real-time gate checks: rely on in-airport monitors or your airline’s app for live gate updates, rather than assuming your boarding pass gate is final gate changes are common in large hub airports

Driving and Parking Options
ATL offers multiple parking tiers, generally including economy, daily, and hourly options at varying price points and proximity to the terminal. Economy lots tend to be the most budget-friendly but require a shuttle to reach the terminal, while daily and hourly lots offer closer proximity at a higher cost.
