The airlines with the worst flight delays from UK airports have been revealed, according to a new investigation. 

Wizz Air was named as the worst airline for flight delays in 2021 with the Hungarian carrier's UK departures being an average of 14 minutes and 24 seconds behind schedule.

The PA news agency investigation, which was conducted from an analysis of Civil Aviation Authority (CAA) data, comes after research that ranked the worst UK airports for delays in July. 

Here is the full breakdown of the airlines with the worst delays last year and on average how long Brits were left waiting to jet off.

The research does not include cancelled flights and on average, the delays across the airlines were eight and a half minutes per flight.

Overall, punctuality across all UK airports last year was better than before the pandemic, due to the introduction of Covid travel restrictions leading to a drop in flights.

However, as many travellers know first-hand, staff shortages have caused major problems for several airports and airlines throughout 2022 and have led to tens of thousands of flights being cancelled.

Guy Hobbs, editor of consumer magazine Which? Travel, said: “While these findings are worrying, the reality has actually been far worse for many travellers this summer.

“Holidaymakers have faced a barrage of disruption over the last few months, and these latest figures only serve to underline the need for urgent reform of the travel industry.

“The Government must drop plans to slash passenger compensation for delayed and cancelled domestic flights.”

Paul Charles, chief executive of travel consultancy The PC Agency, said: “Worsening flight delays have caused enormous stress to many consumers over the last year, as well as financial pain while waiting for refunds and compensation.

“Airlines, airports and air traffic control teams need to work together far more closely and ensure that flying becomes more seamless and more enjoyable for us all.

“That will only happen when staff shortages are properly overcome and the aviation industry can grow again post-pandemic.”
