Five European hubs ranked among the world’s 20 busiest airports in 2025, led by London Heathrow and Istanbul, as the latest ACI World data points to rising pressure on capacity and connectivity across the region.
Europe’s largest airports remained firmly in the global aviation elite in 2025, even as the fastest ranking gains came from Asia-Pacific. New final data from Airports Council International (ACI) World shows global airport traffic reached 9.8 billion passengers last year, up 3.7% on 2024 and 6.5% above 2019 levels, bringing the industry close to the symbolic 10-billion-passenger mark.
For Europe’s travel and tourism sector, the headline is resilience rather than domination. Five European airports made the global top 20 for total passenger traffic: London Heathrow ranked seventh with 84.5 million passengers; Istanbul ranked eighth with 84.4 million; Paris Charles de Gaulle ranked 14th with 72 million; Amsterdam Schiphol ranked 17th with 68.8 million; and Madrid-Barajas ranked 18th, handling 68.1 million passengers. Together, they underline European aviation’s continued role as a tourism engine, with the region’s hubs serving as long-haul gateways for the transfer market, even as Chinese and Southeast Asian hubs climbed sharply.

Heathrow remained Europe’s busiest airport by total passenger traffic, growing 0.7% year on year and 4.4% compared with 2019. Istanbul, meanwhile, continued to show the strongest long-term expansion among Europe-linked hubs, climbing to rank eighth after standing 28th in 2019; its 2025 passenger total was 61.8% above pre-pandemic levels. Madrid also stood out, with traffic 10.4% above 2019, while both Paris Charles de Gaulle and Amsterdam Schiphol were still below their 2019 totals, despite year-on-year growth.
ACI World said the world’s 20 busiest airports handled 1.59 billion passengers, equal to 16% of global air travellers. Its dataset covers 2,817 airports in more than 180 countries and territories, including passenger traffic, air cargo, and aircraft movements.
“Global air travel is approaching a historic milestone, but record demand is also exposing growing pressures on capacity,” ACI World Director General Justin Erbacci said. “The planning and investment decisions made today will determine whether aviation can meet the demands of the next generation of travellers.”
Asia-Pacific growth reshapes the competitive map
While European airports occupy several high-value positions in the ranking, the most dramatic wins happened in the Asia-Pacific region. Kuala Lumpur International Airport entered the top 20 after rising six places to 20th, handling 63.4 million passengers, up 11% year on year. Shanghai Pudong climbed from 10th to fifth with 85 million passengers, while Guangzhou Baiyun returned to ninth globally, after falling as low as 57th in 2022.
Those changes matter for European tourism and aviation businesses because they reflect the renewed strength of outbound and connecting demand from Asia. Improved connectivity with China and other strategic markets supported Kuala Lumpur’s growth, while visa policy easing and expanded international links contributed to Shanghai Pudong’s rebound. For European destinations, airlines and airports, the data points to intense international competition for long-haul traffic and tourism spend.
Atlanta still leads, but international hubs are closing in
Hartsfield-Jackson Atlanta International Airport remained the world’s busiest airport, handling 106.3 million passengers, although it saw a 1.6% decline from 2024. Dubai International Airport ranked second with 95.2 million passengers, up 3.1%, and Tokyo Haneda ranked third with 91.7 million, up 6.7%.
Notwithstanding a challenging couple of years for its travel sector, the US still placed five airports in the top 20, supported largely by domestic traffic. Europe’s leading hubs, by contrast, remain more exposed to international flows, airline network decisions, border processing, slot constraints, and ground infrastructure. Aviation commentators and stakeholders will argue these factors make capacity planning a central issue for the European industry, as demand continues to recover and shift.
Looking ahead, due to the ongoing traffic disruption and low demand caused by the geopolitical conflict in the Middle East, Dubai’s position at two in the list could be at risk in next year’s ranking, which will be based on 2026 data,
