Heathrow has cancelled one in ten scheduled flights today due to poor visibility.
The decision was taken late last night to avoid significant disruption to passengers and flights. However the airport operator has warned that poor weather at other European airports would increase the number of cancellations today.
Passengers have been urged to check the status of their flights before travelling to the airport.
"When there is low visibility, more space has to be left between aircraft. Many airports have plenty of spare runway capacity so aircraft can be spaced out more during low visibility without causing delays and cancellations.
"Because Heathrow operates at almost full capacity, there is simply no room to reschedule the delayed flights," it said.
British Airways said passengers should only travel to the airport if their flight is operating.
"We are doing everything we can to help you if you have been disrupted and we fully apologise for the inconvenience caused to your travel plans.
"Like other airlines at Heathrow we have complied with a request to reduce our schedule by 10% on Monday," the airline said in s statement.
