Busiest Airports in Europe: 2025 Ranking
Europe's top 20 airports ranked by annual passenger traffic per ACI Europe 2025 data. London Heathrow narrowly held onto the top spot with 84.5M passengers, but Istanbul effectively tied at 84.5M and overtook LHR on capacity in early 2026. The post-pandemic recovery is now complete: Europe's airports welcomed an extra 100M passengers in 2025, setting a new record of 2.6 billion. The list mixes legacy hubs (CDG, FRA, AMS) with leisure giants (PMI, BCN) and a fast-growing challenger crop led by Athens, Lisbon, and Copenhagen.

Busiest Airports in the UK
The UK's top five airports handle the bulk of British air traffic, with London commanding four of the five busiest airports in the country. Heathrow alone moves more passengers per year than every airport in Scotland, Wales, and Northern Ireland combined.

Why Istanbul Is Now Europe's #1
Istanbul Airport (IST) has surged from non-existent in 2017 to a virtual tie with London Heathrow at 84.5 million passengers in 2025 — and overtook Heathrow in scheduled seats in April 2026. Three forces explain the rise: Turkish Airlines now flies to more countries (130+) than any airline on earth, IST's geographic position puts 60% of the world's population within a four-hour flight, and the airport's six runways and 90M+ capacity were purpose-built for hub growth when it opened in 2018.
Heathrow, by contrast, is constrained by two runways and a long-running political fight over a third. Until that changes, Istanbul will keep widening its lead.
Brexit and London's Airports
Brexit fears about UK air traffic have not materialised. London Heathrow, Gatwick, Stansted, and Luton all returned to or above 2019 passenger levels by 2024, and Heathrow set a new all-time annual record in 2025. EU-UK aviation rights remained intact under the Trade and Cooperation Agreement, so direct flying capacity was preserved.
Where Brexit did bite was passenger experience: longer e-gate queues for UK arrivals into the EU, and slightly higher ticket prices on UK-EU routes. Gatwick's -1.1% YoY in 2025 reflects route consolidation by easyJet and BA more than any structural Brexit drag.
Hub Airports vs. Leisure Airports
Europe's busiest list mixes two very different airport types. Connecting hubs — LHR, CDG, FRA, AMS, IST, MUC, ZRH — earn their volume from transfer passengers feeding flag-carrier long-haul networks. Leisure giants like Palma de Mallorca, Barcelona, and Athens, by contrast, are almost pure origin-and-destination airports driven by tourism. Palma's seasonal swing alone moves 11M+ summer passengers through a single airport in three months.
Methodology
Rankings are based on total annual passenger traffic (arriving + departing + transfer) for the 2025 calendar year, as reported by ACI Europe's full-year traffic report and verified against individual airport authority releases. Numbers are rounded to the nearest 100,000. ACI Europe is the European region of Airports Council International, the global trade association for airport operators, and is the authoritative source for European airport traffic statistics.
