ACI World 2025 Reveals the World’s Busiest Airports

The Airports Council International (ACI World) has published the 2025 global passenger traffic statistics. According to the released data, Hartsfield–Jackson Atlanta International Airport retained its position at the top of the list of the world’s busiest airports by total passenger traffic, while only two European airports made it into the global top 10: Istanbul Airport and London Heathrow Airport.
Istanbul Airport Maintains Its Position in the Global Top 10
Istanbul Airport served 84,437,710 passengers in 2025, ranking 8th among the world’s busiest airports. Although the airport slipped one position compared to 7th place in 2024, it clearly continues to demonstrate a strong long‑term growth trend.
When compared with 2019, the scale of this rise becomes even more striking. Istanbul Airport ranked 28th globally that year, and by 2025 had climbed into the top tier of global aviation hubs. This upward trajectory highlights the airport’s rapid transformation into a major global transfer and destination hub.
When international passengers only are considered, Istanbul Airport ranked 6th worldwide, handling approximately 84.4 million international travelers. In this category, Istanbul followed closely behind established global hubs such as Dubai, London Heathrow, and Incheon.
U.S. Dominance Continues as Chinese Airports Return to the Top 10
ACI World data confirms that U.S. airports continue to dominate global aviation rankings.
Hartsfield–Jackson Atlanta International Airport once again retained its title as the world’s busiest airport, serving 106 million passengers in 2025. However, Atlanta’s passenger traffic remained 3.8% below 2019 levels, indicating that full recovery has not yet been achieved.
Chinese airports, which accelerated their recovery following the COVID‑19 pandemic, successfully re‑entered the global top 10 by 2025. Shanghai Pudong and Guangzhou Baiyun stood out as the clearest indicators of this rebound.
While Europe was represented by only two airports in the total passenger traffic ranking, the continent achieved broader representation in the international passenger traffic list, with five airports: Istanbul, Heathrow, Amsterdam, Paris, and Frankfurt.

International Passenger Traffic Surpassed 4 Billion
At a global level, international passenger traffic reached 4 billion in 2025, representing:
- a 5.9% increase compared to 2024, and
- an 8.3% increase compared to 2019.
Although Atlanta remained the busiest airport overall, Dubai led the world in international travel. Dubai International Airport handled 95,192,160 international passengers, making it the global leader in this category. Due to the absence of domestic flights within the United Arab Emirates, Dubai’s passenger traffic is entirely international.
In international travel rankings:
- London Heathrow placed second,
- Seoul Incheon ranked third, and
- Singapore Changi ranked fourth.
Amsterdam Schiphol Airport followed in fifth place with 68.7 million international passengers.
Among European airports ranked in the top 10 for international passengers, Istanbul Airport placed sixth, Paris Charles de Gaulle seventh, and Frankfurt Airport ninth.
Air Cargo Traffic
According to 2025 data, global air cargo traffic continued to be heavily concentrated in Asia‑Pacific and North America–based mega hubs. Hong Kong and Shanghai Pudong maintained their positions in the top two, while Anchorage, Louisville, and Miami further strengthened their roles as global and intercontinental transshipment hubs.
E‑commerce, transit freight, and the restructuring of global supply chains emerged as the key factors shaping the performance of the top 10 airports. Despite the decline observed in Memphis, hubs such as Guangzhou, Taipei, and Doha recorded growth. Overall, the data highlights that air cargo remains highly volume‑driven, network‑centric, and concentrated in a limited number of strategically critical hubs.

Factors Supporting Demand, but Outlook Remains Uncertain
According to ACI World, jet fuel prices declined by 13% year‑on‑year in 2025, while easing inflation helped support consumer purchasing power, contributing to stable passenger demand. However, in light of ongoing global economic and geopolitical developments, it is noted that this favorable environment may not continue at the same pace in 2026.
