Europe's airports handled a record 2.6 billion passengers in 2025. We followed every flight departing 31 European countries for a full year to see which airports keep travellers moving on time, and which do not.
Why this matters: the airport you fly from shapes your chances of a long delay more than most travellers realise. For journalists, the gaps between airports, countries and seasons show exactly where Europe's air network is under the most strain.
Key Takeaways
- About one flight in 24 to and from European airports arrived an hour or more late between November 2025 and October 2026.
- Milan Bergamo had the worst record of any large airport, with 60+ minute delays on 9.2% of departures, more than five times the rate at Bergen.
- Germany posted one of Europe's lowest delay rates but one of its highest cancellation rates. Punctuality figures alone do not tell the whole story.
Europe's Busiest Airports by Passengers in 2025
Before looking at punctuality, it helps to know where the crowds are. Passenger numbers grew by 4.4% across Europe in 2025, and the race at the top was extremely close.

Only about 40,000 passengers separated Heathrow from Istanbul across the whole year. Heathrow grew by 0.7% while Istanbul grew by 5.5%, so if those growth rates hold, Europe will have a new busiest airport. Istanbul sits outside the scope of the delay analysis that follows, which covers airports in the EU, UK, Switzerland, Norway and Iceland.
European Air Travel Is Back Above Pre-Pandemic Levels
The pandemic wiped out almost three-quarters of EU air travel in a single year. The recovery line shows how long the climb back took, and where it has gone since.

EU air travel passed its 2019 level for the first time in 2024 and kept growing in 2025, reaching almost 1.1 billion passengers carried, up 4.9% in a year. The growth has not been even, though. ACI EUROPE reports that 41% of European airports were still below their 2019 traffic in 2025, and smaller airports remained about a third down. The recovery has been concentrated at the big hubs and holiday airports.
Which EU Countries Fly the Most Passengers
Four countries dominate EU air travel. Notice how far Spain is ahead, and how many of the top ten are holiday destinations.

Spain carried more than 270 million air passengers in 2025, about a quarter of the EU total and 65 million more than Germany. Greece and Portugal, two smaller countries, both outrank Poland. These tourism-heavy markets matter for the delay figures later on this page: they are also among the countries where flights most often run late.
Europe's Busiest Airports by Flights
Passenger rankings reward airports that handle big aircraft. Counting flights instead shows where Europe's airspace and runways are under the most pressure.

Istanbul handled almost 1,500 flights a day in 2025, well ahead of Amsterdam, Heathrow and Paris CDG, which were separated by fewer than 40 daily flights. Across the whole European network, EUROCONTROL counted 11.1 million flights in 2025, back at 2019 levels, with a record day of 37,034 flights on 18 July.
Europe's Punctuality Is Improving, but Still Below 2019
EUROCONTROL tracks how many flights across its network arrive within 15 minutes of schedule. The trend gives useful context for the airport-level figures that follow.

Punctuality recovered strongly in 2025, with 76.1% of flights arriving on time, up 3.5 points on 2024. It is still two points short of 2019. Air traffic control remains a bottleneck: flights waited an average of 2.4 minutes each for air traffic flow restrictions in 2025, and the en-route share of 1.7 minutes was almost double the EU target of 0.9 minutes.
How Flight Delays at European Airports Changed Month by Month
Delays in Europe follow the calendar, but not quite in the way you might expect. Watch where the line peaks, and compare it with the months when the network was busiest.

The summer rise is no surprise: more flights, fuller skies and tighter turnarounds push delays up from June to August. The bigger surprise is January. It combined one of the lowest flight volumes of the year with the highest delay rate, a sign that winter disruption can hurt the network as much as peak-season crowds. Spring was the calm window, with April the most punctual month by a wide margin.
Cancellations: The Spikes That Delay Figures Miss
A cancelled flight never shows up as "late", so a month can look punctual and still leave thousands of passengers stranded. Splitting cancellations by distance shows what kind of flying was hit.
Source: AirAdvisor's flight database, flights departing airports in the EU, UK, Switzerland, Norway and Iceland, 1 November 2025 to 31 October 2026.
March 2026 had the highest cancellation rate of the year, and more than half of those cancellations were long-haul flights of over 3,500 km. April tells a similar story from the other side: it was the most punctual month for delays, yet its cancellation rate was higher than in most other months. For anyone comparing months, the two measures need to be read together.
Where the Worst Delays Happen: Short, Medium and Long-Haul
Delays of three hours or more matter most to passengers, because that is the point where EU and UK passenger rights start to pay compensation. The distance bands below match the bands used in EU Regulation 261/2004.
Source: AirAdvisor's flight database, flights departing airports in the EU, UK, Switzerland, Norway and Iceland, 1 November 2025 to 31 October 2026.
Short flights of under 1,500 km account for the largest share of long delays simply because they make up most of Europe's flying. The striking figure is the long-haul share: more than a third of all 3+ hour delays came from flights of over 3,500 km, the band that carries the highest compensation amounts.
Which European Countries Have the Most Delayed Flights
National averages hide plenty of variation between airports, but they reveal a clear geographic pattern. Look at which countries sit at each end of the ranking.
Source: AirAdvisor's flight database, flights departing airports in the EU, UK, Switzerland, Norway and Iceland, 1 November 2025 to 31 October 2026.
Europe splits roughly along a north-south line. Cyprus, Portugal, Greece, Malta and Italy top the delay table, and most of them are southern holiday markets where summer schedules stretch airports and airspace. At the other end, Norway, Sweden, Germany, Estonia and Finland all kept 60+ minute delays below 3% of departures.
Delays vs Cancellations: Two Different Kinds of Disruption
When things go wrong, airlines and airports can either run late or cancel. Plotting both measures together shows that countries do not all end up with the same mix.

Germany is the clearest example of the trade-off. It has one of the lowest delay rates in Europe, yet 1.5% of departures were cancelled, among the highest in the region. The Netherlands had the highest cancellation rate of all at 2.5%. Portugal and Greece sit in the opposite corner: frequent delays, but relatively few cancellations. For a traveller, a late flight and a cancelled one are very different problems, so it pays to look at both.
How Europe's Biggest Hubs Compare
The largest airports carry the most connecting passengers, so their punctuality ripples across the whole network. These are the 12 busiest airports in our data, ranked by how often departures arrived an hour or more late.

Frankfurt was the most punctual of the big hubs, while Lisbon, Rome Fiumicino and Barcelona struggled most. Heathrow, the busiest airport in Europe by passengers, kept delays below 4%, a better record than Paris CDG or Amsterdam. Size, in other words, is not the main driver of delays at the top end.
The Most Delay-Prone Airports in Europe
Among large airports, a handful stand out for how often flights run very late. The list leans heavily towards leisure airports and low-cost bases.
Source: AirAdvisor's flight database, flights departing airports in the EU, UK, Switzerland, Norway and Iceland, 1 November 2025 to 31 October 2026.
Milan Bergamo leads by a clear margin, with nearly one departure in ten arriving an hour or more late. Italian and Spanish holiday airports fill most of the table, and three UK airports, Manchester, London Stansted and Edinburgh, also make the cut. Travellers using these airports in summer have good reason to leave extra time for onward connections.
Europe's Most Punctual Large Airports
The best performers are mostly in the north, with a few surprises further south. Each airport here kept 60+ minute delays on fewer than one departure in 30.
Source: AirAdvisor's flight database, flights departing airports in the EU, UK, Switzerland, Norway and Iceland, 1 November 2025 to 31 October 2026.
Nordic airports dominate, led by Bergen, where only 1.7% of departures arrived an hour or more late. Frankfurt is the only one of Europe's five biggest airports on the list, and two Canary Islands airports, Tenerife North and Gran Canaria, show that a sunny holiday destination does not have to mean long delays. Cirium's independent On-Time Performance Review for 2025 points the same way: Oslo (86.0% of departures on time), Copenhagen (84.7%) and Stockholm Arlanda (83.6%) were Europe's best large airports.
Airports with the Highest Cancellation Rates
Cancellations follow a different map from delays. Several airports with respectable on-time records appear here.

Catania had the highest cancellation rate of any large airport, at 3.4%. Amsterdam Schiphol comes second, and three German airports, Berlin, Munich and Frankfurt, all feature. Frankfurt appearing on both the most punctual and the most cancelled lists is the clearest sign that a single metric can flatter an airport.

Methodology
Delay and cancellation figures come from AirAdvisor's flight database, which merges schedule and status data from OAG and other providers. The period covers 12 full months, from 1 November 2025 to 31 October 2026. "Europe" means airports in the 27 EU member states plus the UK, Switzerland, Norway and Iceland. Airport and country figures cover departures; a flight counts as delayed when it reached the arrival gate 60 or more minutes after its scheduled time, and delayed counts exclude cancelled flights. The monthly charts use the database's EU airport filter, which covers flights to and from EU airports.
The database stores one record for each flight number, so a flight sold by several airlines under codeshare agreements appears more than once. For that reason we report percentages, which are not affected by duplicate records, rather than flight counts. Airports were included in rankings if they had at least 50,000 flight records in the period. Passenger numbers, network flight counts and network punctuality are quoted as published by ACI EUROPE, Eurostat, EUROCONTROL and Cirium. These sources use their own geographic scopes: Eurostat covers the EU-27, while ACI EUROPE and EUROCONTROL cover wider Europe, including Türkiye. Eurostat figures reflect the revision of 4 November 2026. Percentages are rounded to one decimal place. All figures are historical; no forecasts are used.
