The worst UK airports for flight punctuality have been revealed, with the longest delays at London Luton.
Departures from the Bedfordshire airport were an average of 20 minutes late in 2017, according to Press Association analysis of Civil Aviation Authority (CAA) data.
London Gatwick recorded the second worst punctuality performance.
The ranking takes into account every scheduled and charter flight from 25 of the UK’s major airports. Cancelled flights are not included.
The average delay across all the featured airports was 15 minutes.
London Heathrow, the UK’s busiest airport, was found to have the best performance, with aircraft typically taking off 11 minutes late.
A spokeswoman for London Luton said: “We regret any delay our passengers experience.”
She added that punctuality was influenced by “many factors” outside its control such as air traffic control strikes, late arriving aircraft, bad weather and congested airspace.
Passengers on delayed flights from UK airports are entitled to assistance and compensation depending on the cause and length of the disruption.
When flights are delayed for more than two hours, airlines have to provide free access to phone calls or emails, meals and refreshments, as well as hotel accommodation if an overnight stay is required.
Passengers can also claim compensation when flights are delayed by more than three hours unless there are “extraordinary circumstances” such as severe weather or a security alert.
