Global air travel reached nearly 9.8 billion passengers in 2025, and Europe’s major hubs continue to hold their own in the international rankings. According to data from Airports Council International (ACI) World, London Heathrow remains the continent’s busiest airport, handling 84.48 million passengers last year. That places it seventh worldwide, down two spots from 2024, though traffic rose 0.7% year-on-year and 4.4% compared to pre-pandemic 2019.
Close on Heathrow’s heels is Istanbul Airport, which recorded 84.43 million passengers. The Turkish hub slipped from seventh to eighth in the global ranking, but its long-term growth is striking: in 2019, it ranked 28th worldwide. Istanbul’s ascent reflects Turkey’s expanding role as a transit point between Europe, Asia, and the Middle East.
Paris, Amsterdam, Madrid round out the top five
Paris Charles de Gaulle took third place in Europe with 72 million passengers, up 2.5% from 2024 but still 5.4% below its 2019 volume. It ranked 14th globally. Amsterdam Airport Schiphol followed with 68.77 million passengers (17th globally), showing a 2.9% increase over 2024 but a 4.1% drop from 2019. Madrid-Barajas rounded out the top five with 68.11 million passengers (18th globally), posting a 3% gain year-on-year and a robust 10.4% rise compared to 2019.
The data underscores a broader recovery: while some Western European airports have yet to fully regain pre-pandemic levels, southern hubs like Madrid are outperforming. The ACI report notes that European airports “remain among the world's largest international gateways, despite operating close to available capacity in several markets.”
International traffic: a European stronghold
When measured by international passengers only, Europe’s airports shine even brighter. Heathrow topped the list with 79.87 million international travellers, making it the second-busiest globally for cross-border traffic. Amsterdam Schiphol came fifth worldwide with 68.76 million international passengers. Other European hubs in the global top ten for international traffic include Istanbul (sixth), Paris Charles de Gaulle (seventh), and Frankfurt (ninth).
Europe’s top ten for international passengers also features Madrid-Barajas, Barcelona-El Prat, Rome Fiumicino, London Gatwick, and Munich. The dominance of these airports highlights the continent’s reliance on air travel for business, tourism, and connectivity—especially for cities like London, Paris, and Rome, which remain key destinations for city breaks and longer stays.
The global picture shows Hartsfield-Jackson Atlanta in first place with 106.3 million passengers, followed by Dubai (95.2 million), Tokyo Haneda (91.7 million), and Dallas Fort Worth (85.7 million). European airports face capacity constraints that may limit further growth, but their role as international gateways remains undisputed.
For travellers, the rankings offer a snapshot of where demand is highest—and where delays and congestion are most likely. As the industry approaches the 10-billion-passenger milestone, Europe’s hubs will need to balance expansion with sustainability and efficiency.
