Flight Delay Statistics in the EU & UK: Insights for 2026
Flights from UK airports are running closer to schedule than at any point since the pandemic, but they still trail the rest of Europe. In 2025, 72.7% of flights at UK airports were on time, against 76.1% across the Eurocontrol network, and the gap has not closed in 2026.
Why this matters: the UK is the second-busiest market in the Eurocontrol area for arrivals after Spain, averaging about 3,300 a day in 2026, and every departure from a UK airport is covered by UK261, the British copy of the EU's EU261 passenger rights rules. The data below compares the two systems side by side: who runs late, which airports and routes are worst, what causes the delays, and what passengers can claim when a flight arrives more than three hours late. For the worldwide picture, see our global flight disruption statistics.

UK vs Europe: On-Time Performance Since 2019
The UK Civil Aviation Authority (CAA) tracks flights at 25 reporting airports, and Eurocontrol, which manages the European air traffic network, tracks arrivals across its whole network area. Both count a flight as on time if it is within 15 minutes of schedule, so the long-run trends are broadly comparable, although the two bodies measure slightly different things.
Source: UK Civil Aviation Authority, Punctuality Statistics, annual summary analyses 2019 to 2025 (2024 and 2025 from the CAA On Time Performance Tables; 2019 to 2023 AirAdvisor calculation weighted by matched flights); Eurocontrol Performance Review Commission, Performance Review Report 2025, March 2026. UK figures cover arrivals and departures; Eurocontrol figures cover arrivals.
The UK fell further in the post-pandemic crunch. In 2022 only 62.5% of UK flights were on time, 9.0 points behind Europe's 71.5%, as staff shortages at airports, airlines and air traffic control produced what Eurocontrol calls the lowest punctuality levels in two decades, in 2022 and 2023. The recovery since then has been steady: 63.7% in 2023, 66.9% in 2024 and 72.7% in 2025, cutting the gap with Europe to 3.4 points. Neither side is back to 2019 yet: the UK is 2.1 points short of its 74.8%, Europe 1.7 points short of 77.8%.
How the numbers are measured: the CAA counts a flight as on time if it arrives at or departs from the gate no more than 15 minutes late, and reports arrivals and departures together. Eurocontrol reports arrival and departure punctuality separately against the same 15-minute line. Compensation works on a different clock: under both EU261 and UK261, what counts is arriving at your final destination 3 hours or more late (UK261: more than 3 hours).
How the UK Compares With EU Countries in 2026
Eurocontrol's daily punctuality data puts every country on the same measure, which makes it the fairest way to line the UK up against its neighbours. The chart covers the 10 countries with the most daily arrivals in the Eurocontrol area in 2026, from 1 January to 23 September.
Source: Eurocontrol, Daily Punctuality Dashboard, stakeholder punctuality data (year to date, 1 January to 23 September 2026), accessed 24 September 2026. Countries selected by average daily arrivals.
Among Europe's 10 busiest markets, only Greece (70.2%) had lower arrival punctuality than the UK (74.3%). Norway led at 85.6%, and the 27 EU states combined reached 77.1%. Departures tell a different story: UK departure punctuality of 73.8% is better than the EU27 figure of 71.6% and ahead of Spain (69.2%), France (68.6%) and Italy (69.8%). In other words, UK airports get flights away on time more often than their EU peers, but flights landing in the UK arrive late more often; the CAA route data further down shows the longest delays on links with Greece, Turkey and France. Across all 42 countries in the dataset, the UK ranks 31st for arrival punctuality.
Which UK Airports Have the Longest Delays?
The CAA publishes full-year figures for each of its 25 reporting airports, from Heathrow's 481,959 flights to Teesside's 3,454. Average delay here covers all flights, so a few very late departures can move the figure as much as many small ones.
Source: UK Civil Aviation Authority, 2025 On Time Performance Tables and 2025 Annual Punctuality Statistics, released in early 2026. All 25 CAA reporting airports, arrivals and departures, scheduled and charter flights.
Manchester had the longest average delay in 2025, at 19.8 minutes, and the lowest on-time rate, 64.5%. Bournemouth (18.4 minutes) and Birmingham (17.8 minutes) followed. At the other end, Aberdeen averaged 10.8 minutes and Liverpool 11.1 minutes, and Liverpool had the highest on-time rate of any UK airport at 80.9%. Heathrow, the UK's busiest airport, averaged just 12.8 minutes, and its on-time rate jumped from 67.3% to 76.7%. Gatwick improved even more, from 59.9% to 69.8%, in a year when Eurocontrol notes it was the only one of Europe's 20 busiest airports with less traffic than in 2024.
Europe's Busiest Airports: Where Arrivals Run Late
The same Eurocontrol dataset covers 112 airports. Restricting it to the 20 with the most arrivals in 2026 gives a like-for-like view of Europe's major hubs, including London's two largest airports.
Source: Eurocontrol, Daily Punctuality Dashboard, stakeholder punctuality data (year to date, 1 January to 23 September 2026), accessed 24 September 2026. The 20 airports with the most average daily arrivals; London airports shown in purple.
London sits at both ends of the table. Heathrow is second only to Oslo (82.5%), with 80.5% of arrivals on time, while Gatwick is second from bottom at 72.0%, ahead only of Athens (67.4%). Lisbon (72.2%) and Zurich (72.8%) complete the weakest group. Beyond the top 20, Manchester's 65.5% is the fourth-lowest of all 112, and the lowest of the 13 UK airports Eurocontrol tracks. Eurocontrol's separate ranking of air traffic flow delay by airport, which put Chania, Athens and Amsterdam at the top in 2025, is covered in our analysis of the most unreliable airlines in Europe.
UK Flight Delays in 2026 So Far
The CAA's monthly releases run to July 2026. Comparing each month with the same month of 2025 shows whether the 2025 recovery is holding.
Source: UK Civil Aviation Authority, Punctuality Statistics 2026, monthly On Time Performance Tables, January to July 2026. 2025 values are the same-month prior-year figures reported in the 2026 tables.
Spring was strong, with 81.7% of flights on time in April 2026, but summer bit. June fell to 65.9% from 69.2% a year earlier, and July matched it at 65.9%, although that was better than July 2025's 61.6%. Average delay reached 19.7 minutes in June and 19.4 minutes in July. Over January to July, 73.8% of UK flights were on time, a fraction below the 74.1% of the same months in 2025, with average delay edging up from 14.5 to 14.7 minutes. Manchester again struggled most: only 51.4% of its flights were on time in July 2026. Our peak travel season delay statistics explain why summer is always the weak point.
UK Routes and Destinations With the Most Delays
The CAA's full analysis breaks every airport's traffic down by origin or destination. To keep the ranking meaningful, the chart only considers routes with at least 5,000 flights in 2025, which leaves 49 airport-route pairs.
Source: UK Civil Aviation Authority, 2025 Annual Punctuality Statistics Full Analysis, released in early 2026 (AirAdvisor calculation: all airlines combined, weighted by matched flights, arrivals and departures at the named UK airport).
Heathrow-Delhi averaged 24.5 minutes of delay per flight, followed by Manchester-Paris Charles de Gaulle (23.1 minutes) and Manchester-Alicante (21.7 minutes). Manchester appears four times in the top 10. The three most punctual busy routes all link Heathrow with Scandinavia: Copenhagen (7.2 minutes), Stockholm Arlanda (7.5) and Oslo (7.6). By country, flights between the UK and Greece were the most delayed of the 17 countries with more than 20,000 flights: 22.8 minutes on average, with only 56.7% on time. Turkey (17.7 minutes) and France (17.3 minutes) came next, and Denmark had the shortest average delay at 10.4 minutes.
What Causes Flight Delays in Europe and the UK
Eurocontrol's Central Office for Delay Analysis (CODA) collects airline delay codes and sorts departure delay by cause. Its latest monthly release, for August 2026, allows a like-for-like comparison with August 2025.
Source: Eurocontrol CODA, All-Causes Delay to Air Transport in Europe: August 2026, 22 September 2026 (based on partial airline data, 55.3% coverage). Weather combines ATFM weather and other weather; Other combines government, other airport and miscellaneous causes. Components may not sum to the total because of rounding.
Average departure delay in Europe rose to 19.3 minutes per flight in August 2026, from 17.0 minutes a year earlier. The biggest single cause is reactionary delay, the knock-on effect of an aircraft arriving late for its next flight, which accounted for 9.3 minutes, or 48% of the total. Airline causes such as crew, maintenance and ground handling added 4.1 minutes, and en-route air traffic flow management (ATFM) restrictions, where aircraft are held because airspace is full, added 3.4 minutes. Eurocontrol calculates that in 2025 every minute of primary delay generated 0.79 minutes of reactionary delay later in the day.
The CAA does not publish delay causes, but Eurocontrol's records show how single events hit UK flights. A radar issue at the London Area Control Centre on 30 July 2025 caused 26,304 minutes of ATFM delay, plus 9,936 minutes in neighbouring states. On 20 March 2025 a fire at an electrical substation near Heathrow closed the airfield until the evening of 21 March: about 114 inbound flights diverted and around 1,200 expected flights did not operate.
Flights Delayed More Than 3 Hours: The Compensation Zone
A delay of 15 minutes is an annoyance; a delay of more than 3 hours is where passenger rights begin. The CAA's delay bands show how many flights at UK airports crossed that line.
Source: UK Civil Aviation Authority, Punctuality Statistics, annual summary analyses 2019 to 2025 and monthly summary analyses January to July 2026 (AirAdvisor calculation: flights 181 to 360 minutes late plus flights more than 360 minutes late, as a share of matched flights). 2026 covers January to July only.
10,465 flights at UK airports were more than 3 hours late in 2025, 0.55% of all matched flights, or roughly 1 in 180. That is down from 15,276 (1.00%) in 2022 but still above the 9,809 (0.48%) of 2019. January to July 2026 ran at a similar rate, 0.53%, or 5,879 flights. These are flights measured at the UK airport, and they exclude cancellations, so they are an indicator rather than a count of claims: a late flight can make up time in the air, delays caused by extraordinary circumstances earn no compensation, and a passenger who misses a connection can reach the final destination more than 3 hours late after a much shorter first delay.
EU261 vs UK261: What Passengers Can Claim
After Brexit, the UK copied Regulation (EC) No 261/2004 into British law, with the compensation converted into pounds. The two regimes now run in parallel, and which one applies depends on where the flight departs and which airline operates it.
| Rule | EU261 | UK261 |
|---|---|---|
| Flights covered | Departing an EU airport (any airline), or arriving in the EU on an EU airline | Departing a UK airport (any airline), or arriving in the UK on a UK or EU airline |
| Delay threshold for compensation | 3 hours or more at final destination | More than 3 hours at destination |
| Up to 1,500 km | 250 EUR | 220 GBP |
| 1,500 to 3,500 km (and intra-EU over 1,500 km) | 400 EUR | 350 GBP |
| Over 3,500 km, 3 to 4 hours late | 300 EUR (50% reduction allowed) | 260 GBP |
| Over 3,500 km, more than 4 hours late | 600 EUR | 520 GBP |
| Extraordinary circumstances | None (e.g. severe weather) | None (e.g. extreme weather) |
EU261's delay compensation rests on the Court of Justice's 2009 Sturgeon ruling, which gave delayed passengers the same rights as those whose flight was cancelled. The rules are about to change on the EU side, but not the amounts: under the agreement announced by the European Commission on 15 June 2026, passengers keep the right to claim after a 3-hour delay, with the 250, 400 and 600 euro bands unchanged. Parliament approved the agreed text on 7 July 2026 and the Council gave its final clearance on 13 July 2026; the revised rules apply 12 months after publication in the Official Journal. UK261 is unaffected.

Outlook
The UK closed most of its post-pandemic gap with Europe in 2025, but 2026 has stalled rather than extended that recovery: UK punctuality for January to July is flat on 2025, and a weak June and a poor August across Europe show how quickly summer weather and knock-on delays erode the gains. Traffic keeps growing at the big hubs where most delays concentrate; see our busiest airports statistics for the volumes. For passengers, the practical point is unchanged in both systems: a flight that arrives more than 3 hours late, for reasons within the airline's control, can be worth up to 520 GBP or 600 euros.

Methodology Note
UK figures come from the CAA's punctuality statistics, which cover arrivals and departures at 25 reporting airports (26 before 2024, when the airport set changed) and count a flight as on time if it is no more than 15 minutes late. The 2024 and 2025 national and airport figures are taken directly from the CAA On Time Performance Tables; 2019 to 2023 national figures, the January to July 2026 totals, the route and country rankings and the more-than-3-hours shares are AirAdvisor calculations from the CAA summary and full analysis files, weighted by matched flights, so they can differ from CAA totals in the last decimal. Route rankings combine all airlines on an airport-route pair and both directions, and include only pairs with at least 5,000 matched flights; country rankings include only countries with more than 20,000 flights. Monthly 2025 comparisons use the prior-year values printed in the 2026 tables. European network punctuality (76.1% in 2025, 77.8% in 2019) follows the Eurocontrol Performance Review Report 2025; Eurocontrol's European Aviation Overview and daily dataset give 78.1% for 2019 because they use a slightly different flight population. Country and airport comparisons for 2026 use Eurocontrol's daily punctuality dataset for 1 January to 23 September 2026; this file is updated daily, and the EU27 figure is AirAdvisor's aggregate of punctual and scheduled arrivals for the 27 member states. CAA and Eurocontrol figures are not identical measures: the CAA combines arrivals and departures at UK airports, while Eurocontrol reports arrival and departure punctuality separately. Delay-cause figures are from a single month of partially complete CODA data (55.3% coverage) and may be revised. Flights more than 3 hours late at a UK airport are not the same as compensation claims, which depend on arrival time at the final destination and the cause of the delay. Percentages are rounded to one or two decimals.
