ATL Airport Guide: Navigate the World’s Busiest Hub

Hartsfield-Jackson Atlanta International Airport (ATL) handles over 100 million passengers annually, making it the world’s busiest airport by passenger traffic. With five parallel runways and flights to more than 150 destinations via 23 airlines, primarily Delta Air Lines, ATL serves as a critical hub for domestic and international travel.

Airport History and Key Facts

Named after William B. Hartsfield, Atlanta’s longest-serving mayor who transformed the city into an aviation powerhouse, and Maynard H. Jackson Jr., the first African American mayor of a major southern city, ATL has evolved into a global gateway. The airport features the Domestic Terminal and Maynard H. Jackson Jr. International Terminal, connected by efficient underground transport systems.

Terminal and Concourse Layout

ATL’s layout centers around the Domestic Terminal, divided into North and South sections, which feeds into seven concourses (A through F and T) via the Plane Train. The International Terminal, at 2600 Maynard H. Jackson Jr. Blvd, handles all global arrivals and departures with dedicated customs and immigration.

• Domestic Terminal North: Serves United, American, and non-SkyTeam airlines for check-in and baggage.
• Domestic Terminal South: Delta’s primary hub.
• International Terminal: Modern design with glass facade; includes Concourse F for long-haul flights and SkyTeam partners.

Concourse T connects directly to international operations. Concourses A and B dominate Delta’s major domestic routes, while D handles smaller aircraft. Gates are often at concourse ends, so plan for walking distances up to a mile.

Concourse Quick Reference

Getting Around ATL Efficiently

The Plane Train is the fastest way to zip between concourses, running underground every 2 minutes. It stops at all gates, bypassing long walks. For international connections, clear customs at the International Terminal, recheck bags if needed, then reclear security for domestic flights.

• Short layovers (under 90 minutes): Stay airside; Plane Train handles most transfers.
• Long layovers: Explore concourse amenities or exit to the city.

Walking is viable but concourses are lengthy—A1 to A34 can take 20+ minutes. Use moving walkways where available.

Security Screening Essentials

Arrive 2 hours early for domestic flights and 3 hours for international. Peak times (5-9 a.m., holidays) see longest lines. All checkpoints access every concourse.

Track real-time TSA wait times via the official ATL app or website. Note: From February 1, 2026, ID-less travelers pay $45 for identity verification. Construction may extend domestic screening times—arrive extra early.

Parking Options and Tips

ATL offers on-site parking with reservations via Park ATL to avoid circling. Due to construction, use Park-Ride lots or ATL West Deck. Check lot status online.

• Hourly/ATL Daily: Closest to terminals, pricier.
• Economy/Park-Ride: Shuttle service, budget-friendly for long stays.
• Off-site: Secure lots with patrols, cameras; ranked safest for 2026.

For security, prioritize well-lit lots with 24/7 monitoring. Reserve ahead, especially during peaks.

Ground Transportation and Access

MARTA subway connects ATL to downtown Atlanta (15-20 minutes, $2.50). Taxis, rideshares (Uber/Lyft), and shuttles queue curbside. Rental cars return to dedicated lots with shuttles to terminals.

• Rideshare pickup: Domestic North/South and International levels.
• Hotel shuttles: Designated zones post-baggage claim.

Dining, Shopping, and Layover Activities
