London Luton Airport is the worst in the UK for delays, according to figures compiled by the Press Association.

Using data from the Civil Aviation Authority, the organisation found passengers at the airport could expect an average delay of 19.7 minutes on each flight.

This is almost twice as long as delays at the best performing airport, London Heathrow, where each plane is delayed by an average of 11 minutes.

According to the punctuality figures Gatwick, Jersey and Durham Tees Valley were the next worst performing airports.

Scheduled and charter flights, but not cancelled services, from the 25 busiest airports were examined in the study.

The Press Association said flights across all airports left an average of 15 minutes late.

Leeds Bradford, Belfast City and London City were also among the top performers.

The CAA said the data allows passengers to “make informed choices about which airports they fly from”.

A Luton airport spokeswoman said factors outside its control had an influence on punctuality including air traffic control strikes, late arriving aircraft, bad weather and congested airspace.
