Passengers using Gatwick face the most flight delays in the UK, according to a report published today.
Aviation data analysed by BBC News uncovered the routes and airports where customers faced the worst punctuality.
Passengers using Gatwick experienced average delays of 18 minutes per flight. The airport said it regretted any delays.
The most delay-hit flight was from Manchester to New York which was delayed by an average of 88 minutes.
The BBC England data unit analysed Civil Aviation Authority data from January 2015 to March 2016.
The investigation showed that a Pakistan International Airlines flight from Manchester to New York John F Kennedy airport was late on eight out of 10 recorded flights in 2015.
Turkmenistan Airlines had the highest number of delays with passengers waiting on average 70 minutes beyond their scheduled time.
The average delay among all airlines was about 15 minutes.
Gatwick’s punctuality record compared with an average of 13 minute delays at Heathrow, the only airport with a larger number of flights, and just under 11 minutes per flight from Newcastle airport over the same period
A Gatwick spokeswoman said: “We regret any delays our passengers experience however several incidents beyond Gatwick’s control influenced the airport’s performance during this period, including numerous air traffic control strikes across European airspace, impacting the airport’s whole flight schedule including our long haul routes.
“Gatwick has more flights to Europe than any UK airport and can therefore be impacted disproportionately by events on the continent.”
Out of 129 PIA flights from Manchester to New York between January 2015 and March 2016, delays totalled almost 190 hours, an average of 88 minutes per departure.
A spokesman for Manchester airport said: “The Pakistan International Airlines service doesn’t impact on any other flights operating from Manchester.”
The next most delayed flight was the Turkmenistan Airlines service from Heathrow to Ashgabat, Turkmenistan, with 19,302 minutes of delays out of 259 flights, equivalent to almost an hour and a quarter per flight.
Flights to Chambéry in France, typically popular for skiing holidays, also made up four of the 10 most delayed flights.
However, Jet2.com, which ran three of those, stopped flying to Chambéry from UK airports in April 2016.
Analysis by consumer group Which? previously suggested almost a quarter (24%) of the 1.9 million flights to or from the UK between April 2015 and March 2016 were delayed by 15 minutes or more.
