The worst UK airports for flight delays
No one wants to be stranded at an airport. Delays add more stress to the air travel experience, affecting millions of passengers every year in the UK. This blog will highlight which airports, airlines and routes to avoid.
The busiest airports in the UK:
There are many international airports spread across the UK, as well as lots of smaller ones operating domestic and private flights. For the purposes of their research, the Civil Aviation Authority (CAA) focus on the 25 biggest ones.
Heathrow is the largest and busiest airport in the UK; it handled 75 million passengers in 2016, nearly double the amount that passed through Gatwick during the same time period. With its four terminals hosting international (short and long-haul), domestic and connecting flights, Heathrow dealt with over a quarter of the 1.7 million flights that departed the UK’s 25 major airports over the course of 2016.
Each one of the Top 10 busiest UK airports saw an increase in passenger numbers in 2016. The most significant surges were at Stansted, Luton and Glasgow, which all experienced double-digit passenger growth last year.

What are the chances of being delayed?
According to the Civil Aviation Authority, passengers flying to popular holiday destinations from the UK, have a 20% chance of enduring an airport delay of at least 30 minutes. In 2016, a staggering 38,000 international flights took off behind schedule during the peak summer months alone.
Which airport are you most likely to get delayed at?
London is the biggest city in the UK and has four major airports serving it, including two of the busiest in Europe. Therefore, it is not surprising that most UK delays involve flights from Heathrow, Gatwick, Stansted and Luton. When looking at proportion of flight delays over 30 minutes, Gatwick came out as the worst of 25 UK airports, with nearly a third of its international departures disrupted during the summer of 2016. Luton and Stansted also make the Top 10 list of frequently delayed airports, with approximately one in five flights being delayed at both.
Belfast International has the second highest percentage of delayed flight, with just under a quarter of departures being at least 30 minutes late.
Both of Scotland’s major international airports make the list too, with just under 20% of each airport’s flights getting delayed by more than 30 minutes between June and September 2016.
The UK’s most regularly delayed airports:
|London Gatwick||30 minutes|
|Belfast International||23 minutes|
A staggering 38,000 international flights were late departing major UK airports last summer.
How long should you expect to be delayed for?
Delays will vary significantly in length, with some lasting a matter of minutes, and others extending beyond several hours. The average delay across major UK airports last summer was 21 minutes. The longest delay to happen at a UK airport during this time was a flight from Manchester to Dusseldorf, which got delayed for an astonishing 779 minutes – that’s nearly 13 hours!
Which routes suffer the longest delays?
Although Manchester to Dusseldorf tops the list, there are many other routes which averaged delays well in excess of 200 minutes between June and September last year. Popular destinations featured in the Top 10 include Oslo, New York and Warsaw.

- Gatwick to Cunagua Cayo Coco
- Edinburgh to Oslo Gardermoen
- Jersey to Dusseldorf
- Birmingham to Malta
- Belfast International to Burgas
- Bristol to Thira Santorini
- Gatwick to New York JFK
- Gatwick to Warsaw Chopin
- Heathrow to Split
Which routes get delayed most frequently?
Of the top 40 delay-prone routes flown from the UK three-quarters were heading to European destinations.
The non-European flights that were regularly delayed last summer were bound for Ghana, Canada, USA and Pakistan.
The most repeatedly delayed route was from Heathrow to the Ghanaian capital, Accra – 85 out of 122 flights on this route were at least 30 minutes late during the peak summer months.
When are delays most likely to happen?
All UK airports seemingly experience more delays in June than any other summer month.
Last September, a flight from Manchester to Dusseldorf was delayed for an incredible 13 hours.
What are the UK’s most delayed airlines?
The Civil Aviation Authority have analysed 850,000 flights at 25 UK airports across the entirety of 2016. A quarter of all these flights arrived behind schedule, with Air Transat, Icelandair and Norwegian Air among the most frequently late airlines.
At the other end of the scale, KLM were the most punctual ahead of Qatar Airways, Iberia, Aer Lingus and Etihad Airlines.
When looking exclusively at UK-based airlines, EasyJet have the worst punctuality record, with only two-thirds of their flights arriving on time. Low-cost rival Ryanair had a much higher punctuality rate of 77 per cent and British Airways managed to get 74 per cent of their flights to destinations on time.
The most punctual UK airline in 2016 was Flybe – the Exeter-based carrier landed 82 per cent of their flights on schedule, serving approximately 7 million passengers in the process.

Dining and shopping amenities are deemed less important along with peripheral attractions – however, these factors are likely to become more important for passengers enduring flight delays.
