Heathrow Airport is telling passengers to check with their airline after dozens of services were cancelled because of freezing fog.

The Independent reports 70 British Airways flights were grounded on Sunday, with ‘at least’ 85 BA flights cancelled today. It adds other airlines are also affected.

A BA spokesperson said: “Like other airlines, our schedule has been affected by the continued freezing fog weather conditions experienced across London.

“We’ve apologised to customers whose flights have been affected and are doing everything we can to get them on their way as quickly as possible.”

A Heathrow spokesperson said: “Poor visibility is forecast this morning at the airport and across the South East.

“While there may be minor changes to today’s schedule as a result of the weather, we want to reassure passengers that our colleagues are working in close collaboration with our airline and air traffic control partners to get them safely away on their journeys as quickly as possible.

“We encourage passengers to check with their airline for the latest information.”
