Atlanta Hartsfield-Jackson International Airport (ATL) has once again secured its position as the busiest airport on the globe. According to a recent press release from Delta Air Lines, Airports Council International (ACI) World officially awarded the title to the Georgia-based hub after it served more than 106 million passengers in 2025.
The achievement highlights a long-standing streak of dominance for the airport. Official company statements note that ATL has held the title of the world’s busiest airport for 27 of the past 28 years, with the sole exception occurring in 2020 during the height of the global pandemic.
Delta Air Lines, which operates its primary hometown hub out of Atlanta, continues to be the driving force behind the airport’s massive passenger volumes. The airline’s extensive network and ongoing infrastructure investments have cemented ATL’s status as a critical node in global aviation.
Driving Global Connectivity
Modernizing the Hub Experience
To support the staggering volume of travelers passing through Atlanta, Delta Air Lines has committed heavily to infrastructure and passenger experience upgrades. The airline’s press release details that Delta has invested more than $12 billion into modernizing its broader hub network. At Hartsfield-Jackson specifically, these funds have been directed toward enhanced concourses, upgraded Sky Clubs, and the implementation of innovative technologies such as TSA PreCheck Touchless ID, which aims to streamline the journey from curb to gate.
The scale of Delta’s operations at ATL remains unmatched. According to the company, the carrier currently operates nearly 1,000 peak-day departures from the Atlanta hub. These flights connect passengers to 207 destinations across the globe, including 61 international markets.

State and City Leaders Weigh In
The symbiotic relationship between Delta Air Lines and the state of Georgia dates back to 1941. Today, the airline notes it employs more than 37,000 residents in the state, making it a cornerstone of the local economy. Local leaders were quick to praise the collaborative efforts that keep the airport at the top of global rankings.
In the official release, Atlanta Mayor Andre Dickens emphasized the broader impact of the airport’s success:
“Hartsfield-Jackson Atlanta International Airport is more than just a gateway to the world; it is an economic engine for our Atlanta and our state. As ATL once again leads the world in passenger traffic, we celebrate the employees, partners, and airlines like Delta who make this possible through teamwork and investment.”
