Thousands of travellers at Heathrow Airport are facing cancellations as freezing fog covers parts of the country.

More than 80 British Airways flights have reportedly been grounded and 12,000 of the airline’s passengers could be impacted overall.

Numerous other airlines have also been affected as temperatures of -5°C hit this morning.

Flights to European spots like Amsterdam, Paris, Milan and Barcelona appear to have been affected.

The number of planes landing at the UK’s busiest airport has been reduced.

A spokesperson for Heathrow confirmed poor visibility was a problem this morning.

But they insisted changes to the schedule were ‘minor’, with freezing fog expected to clear in a few hours.

On Sunday, at least 70 British Airways flights were cancelled due to fog.
