Two of the least punctual airlines in the UK fly from Bristol Airport, an investigation has revealed.
Thomas Cook and Wizz Air were the second and third worst in the country for departure delays, the report by the Press Association found.
On average, Thomas Cook journeys were 24 minutes late in 2018, while Wizz Air flights were 23 minutes delayed.
Press Association analysed Civil Aviation Authority data and only airlines with more than 2,000 UK flights every year. It did not include cancelled flights.
A Thomas Cook Airlines spokeswoman said: “A variety of factors, including air traffic control strikes in Europe and periods of severe weather, contributed to record levels of disruption across the industry in 2018.
“Unlike many airlines, we almost never cancel flights because we want get our customers away on holiday, so these factors had a particular impact on our punctuality figures.
“We had a significant period of growth in 2018 with new routes and slots at UK airports. Our customers are our first priority when a flight is delayed and we always want to get them on holiday on time.
“We have taken steps to improve punctuality this year, including operating more reserve aircraft to help get flights back on time quickly if delays happen.”
Overall flights from the UK are delayed by 16 minutes on average.
Spanish carrier Vueling was least punctual, with departures on average 30.5 minutes late last year.
Meanwhile, Cathay Pacific was the most punctual despite its flights still taking off eight minutes late on average.
A Vueling spokesperson told Sky News that punctuality was "hugely affected" by industrial action in France last summer.
They said: "During these strikes, Vueling flights to and from Barcelona and the UK could not fly straight across France but instead flew south of the Pyrenees and into the Atlantic before looping back towards Britain.
"All airlines have been affected by air traffic control issues in Europe, but the location of Vueling's [Barcelona] hub close to Marseille means it has been particularly badly affected."
They also said the carrier has added up to 10 extra planes to fly during disruption.
