Fog causes flight delays at Gatwick Airport for a third day

Fog is continuing to disrupt flights at Gatwick Airport with restrictions imposed to maintain safety.

On what is expected to be the airport's busiest day of the Christmas period, it said some flights "may be delayed throughout the day" due to "poor visibility" and apologised to customers.

While the weather is improving, the UK's main air traffic control provider Nats said temporary air restrictions are still in place for some airports in London.

Hundreds of flights have already been cancelled and delayed across some of the UK's major airports since Friday, with passengers still advised to check their flight before travelling.

Gatwick's arrivals and departures boards show delays but no cancellations.

Sunday is expected to be its busiest day during the holiday period, with 769 flights planned.

Heathrow meanwhile said it was operating as normal, with no cancellations due to the fog. Its arrivals and departure boards were earlier showing some delays and cancellations, but it is not known if they were fog-related.

Stansted and Luton airports have also said they are not affected.

BBC Weather said the fog is not as extensive or thick as it has been for the past two days, adding it is mostly in central and south England and south Wales and should disperse from some areas by Sunday afternoon.

But even when the fog dissipates, many planes and pilots may be out of place due to the previous delays and cancellations, which is likely to bring further disruption to air travel.

Flights at Manchester, Glasgow and Cardiff were among the airports where flights had also been disrupted on Friday and Saturday.
