Hartsfield-Jackson Atlanta International Airport (ATL) has been the busiest airport in the world for 26 out of the last 27 years. In 2024, the airport served approximately 108 million passengers, a 3% increase from 2023. ATL is located in Atlanta, Georgia, and is the home base and megahub of Delta Air Lines.
The airport's extensive support facilities include a fire station and a maintenance complex that is home to Delta TechOps. ATL has also been expanding and upgrading its infrastructure to accommodate its high volume of passengers. For example, the north end of Concourse T was extended, adding five new gates and improved holdroom space. A new West parking deck with 5,700 new spaces has also been constructed, and a new South parking lot is being expanded to seven levels and nearly 7,000 spaces.
In addition to its passenger volume, ATL is also a Top 20 global airport for cargo tonnage. The ATLNext program aims to increase the airport's cargo aircraft parking capacity and add over one million square feet of warehouse space. The program has been operational for nearly a decade and has made significant progress.
Hartsfield-Jackson Atlanta International Airport's ranking as the busiest airport in the world is determined by Airports Council International (ACI), which measures total passengers enplaned, deplaned, and in direct transit. ACI's rankings are based on data from over 2,700 airports worldwide.
Looking forward, global passenger traffic is forecast to reach 9.9 billion in 2025, a 4.8% year-over-year growth rate. Despite the challenges posed by the COVID-19 pandemic, Hartsfield-Jackson Atlanta International Airport has consistently maintained its position as one of the world's busiest airports.

Dubai International Airport (DXB) is the second busiest airport
Dubai Airport's ranking is based on total passenger traffic, which includes passengers enplaned, deplaned, and in direct transit. In 2024, Dubai International Airport handled over 92 million passengers, a significant number that contributed to its ranking as the second busiest airport globally.
Dubai's position as the second busiest airport is impressive, considering the impact of the COVID-19 pandemic on air travel. In 2020, travel restrictions caused a dip in passenger traffic, affecting Dubai and many other airports worldwide. However, Dubai International Airport has shown resilience, retaining its high ranking despite these challenges.
Dubai International Airport's success can be attributed to its role as a vital hub for international travel. When considering only international passengers, Dubai Airport takes the top spot, surpassing even Hartsfield-Jackson Atlanta International Airport (ATL). Dubai's dominance in international travel is further highlighted by the absence of any U.S. airports in the top 10 rankings for international passengers.
Dubai International Airport's continued ranking as the second busiest airport in the world underscores its significance as a global travel hub. With Emirates Airlines using it as their home base, Dubai has solidified its position as a key player in the aviation industry, connecting travellers from all over the world.

Hartsfield-Jackson Atlanta International Airport in Georgia has been the busiest airport in the world for 26 out of the last 27 years.

It offers non-stop flights to 249 destinations across North America, South America, the Caribbean, Europe, Africa, Asia, the Middle East, and the North Atlantic region.
O'Hare has consistently ranked among the world's busiest airports each year. In 2019, it had 919,704 aircraft movements, the most of any airport in the world, owing in part to a large number of regional flights. O'Hare's growth was initially slow, as airlines were reluctant to move from Midway International Airport, which was then the world's busiest airport. However, in July 1962, the last fixed-wing scheduled airline flight in Chicago moved from Midway to O'Hare, making it the world's busiest airport.
