Hartsfield-Jackson Atlanta International Airport: The World's Busiest Airport
Overview and History
Hartsfield-Jackson Atlanta International Airport (ATL) holds the distinction of being the world's busiest airport by passenger traffic and aircraft operations. Located seven miles south of downtown Atlanta, Georgia, the airport serves as a major hub for Delta Air Lines and a focus city for Southwest Airlines. The airport's history dates back to 1925 when it began as an abandoned auto racetrack named Candler Field.
The airport was renamed in 2003 to honor former Atlanta mayors William B. Hartsfield and Maynard Jackson, both of whom played crucial roles in the airport's development. Today, ATL covers approximately 4,700 acres and features two terminals and seven concourses with a total of 195 gates.
Infrastructure and Operations
Terminal Layout
The airport's domestic terminal is divided into two main areas: the North Terminal and South Terminal. The international terminal, known as the Maynard H. Jackson Jr. International Terminal, opened in 2012 and features 12 gates capable of handling the world's largest passenger aircraft.
The seven concourses (T, A, B, C, D, E, and F) are connected by the Plane Train, an automated people mover system that runs underground between terminals. The airport also features the ATL SkyTrain, which connects the airport with rental car centers and Georgia International Convention Center.
Runway System
ATL boasts five parallel runways, making it one of the few airports in the world with such extensive parallel runway capacity. This configuration allows for efficient simultaneous operations and contributes to the airport's ability to handle high volumes of air traffic.

Recent Developments and Challenges
Operational Disruptions
The airport has faced several operational challenges in recent times:
Flight Reductions (November 2025)
The Federal Aviation Administration mandated a 10% reduction in air traffic at 40 major airports, including Atlanta, amid an ongoing government shutdown. This led to the cancellation of at least 86 flights and delays for over 320 others, significantly impacting Delta Air Lines operations.
Air Traffic Control Tower Evacuation (October 2025)
The airport's air traffic control tower was evacuated following a fire alarm and reports of a gas odor, causing significant flight delays and cancellations. Operations resumed after Atlanta Fire Rescue Department confirmed no gas presence.
TSA Staffing Shortages (October 2025)
Passengers experienced longer wait times at TSA checkpoints due to staffing shortages, resulting in 161 delayed flights and two cancellations by mid-day.
Infrastructure Issues
Ceiling Leak (August 2025)
A significant water leak occurred near Gate T11, causing part of the ceiling to collapse. Remediation crews promptly addressed the issue, though it highlighted ongoing maintenance challenges in the aging facility.
Funding Challenges
DEI Policy Impact (September 2025)
The airport forfeited $37.5 million in federal funding due to its commitment to diversity, equity, and inclusion policies. The FAA withheld participation in several projects, including taxiway pavement replacement and terminal restroom renovations, because the city declined to sign standard grant offers that conflicted with its DEI stance.
Future Projects and Expansion
The airport continues to pursue modernization and expansion projects, including:
Despite funding challenges, the city is exploring alternative funding sources to proceed with critical infrastructure projects.
Traveler Experience
Hartsfield-Jackson offers numerous amenities for travelers, including:
Strategic Importance
As the primary hub for Delta Air Lines, ATL plays a crucial role in global air transportation. Its strategic location in the southeastern United States makes it an ideal connecting point for domestic and international travel. The airport serves as a gateway to the Caribbean, Latin America, Europe, and Asia, with direct flights to numerous international destinations.
The airport's continued growth and development remain essential to maintaining Atlanta's position as a major global city and transportation center. Despite operational challenges, Hartsfield-Jackson continues to adapt and innovate to meet the demands of 21st-century air travel.
