Top 10 Busiest Airports Around the World in 2025
Hartsfield–Jackson Atlanta International Airport Retains Title as World’s Busiest Airport in 2025
The latest rankings for the world’s busiest airports in 2025 have been released, highlighting continued growth in global air travel. Passenger traffic increased significantly last year, with the world’s leading airport maintaining its long-held position. However, growing geopolitical tensions and economic uncertainty are creating concerns for the aviation industry in 2026.
Preliminary data released Tuesday by Airports Council International estimates that worldwide passenger traffic reached 9.8 billion travelers in 2025. This represents a 3.6% increase compared to 2024 and a 7.3% rise above pre-pandemic 2019 levels. ACI, which represents more than 2,200 airports across 181 countries, is expected to publish finalized figures in July.
Once again, Hartsfield–Jackson Atlanta International Airport claimed the top position as the busiest airport in the world, serving approximately 106.3 million passengers in 2025. Despite remaining in first place, the airport recorded a slight 1.6% decline from 2024 and nearly 4% fewer passengers compared to 2019 figures.
The Atlanta airport has held the global No. 1 ranking for 27 of the past 28 years, losing the title only in 2020 during the severe downturn in air travel caused by the Covid-19 pandemic.
Dubai International Airport maintained its position as the second busiest airport globally for the third straight year, while Haneda Airport moved up one place to secure the No. 3 spot in 2025.
Rounding out the top five were Dallas Fort Worth International Airport in fourth place and Shanghai Pudong International Airport in fifth.
Justin Erbacci, Director General of Airports Council International, told CNN Travel that passenger growth was seen across most global regions, driven largely by the continued recovery in international travel. He also noted that passenger growth in the United States has recently started to stabilize after several years of strong expansion.
Although airport traffic remained strong throughout 2025, the outlook for 2026 remains uncertain due to several ongoing challenges, including geopolitical instability and concerns surrounding the global economy.
Among the airports facing operational challenges is Dubai International Airport, which also ranks first globally for international passenger traffic. Since the beginning of the conflict in the Middle East, Dubai and several other regional airports have experienced significant operational disruptions.
Erbacci explained that it is still too early to fully determine the long-term impact of the conflict and broader global uncertainty on air travel demand. However, he warned that prolonged instability in the Middle East could create wider disruptions across the aviation industry.
Rising fuel prices are already contributing to higher airfare costs worldwide, while many travelers have begun choosing alternative flight routes to avoid areas affected by recent operational interruptions, including Dubai.
According to Erbacci, fuel supply itself could become an even greater concern if the situation continues.
“If the conflict continues much longer, pressure on fuel availability could start affecting airline route decisions,” he told CNN Travel shortly before the announcement of a cease-fire agreement, which may still face uncertainty.
He added that a prolonged crisis could also place additional pressure on the global economy and inflation, potentially influencing how frequently people travel, where they choose to fly, and the way they travel overall.
Despite these concerns, demand for travel remains strong. ACI expects the fastest future growth to come from regions such as Africa, the Middle East, and Asia-Pacific, while North America and Europe are forecast to continue seeing slower but stable growth.
Erbacci said the aviation industry remains resilient and is expected to continue expanding, although geopolitical developments could still reshape the pace and direction of future growth.
