LONDON - Thick fog is disrupting flights across Britain, with about 45 flights at Heathrow airport having been cancelled since Sunday and London cancelling all in and outbound flights until at least 11:00 GMT Monday (Nov 2; 7pm Singapore time), the BBC reported.
Others affected airports include Manchester, Leeds Bradford, Glasgow, Belfast and Cardiff, the broadcaster said.
It quoted Easyjet as saying it was suffering "major network disruption today due to poor weather conditions throughout Europe causing low visibility".
"This has resulted in a large number of aircraft and crew out of place for flights today," the airline said.
"In addition we are seeing a lot of Air Traffic Control restrictions which has resulted in some delays, diversions and cancellations."
British Airways have cancelled more than 100 of its flights on Monday - mostly to and from its main base, London Heathrow, and the Docklands airport, London City, The Independent reported.
“Please do not come to the airport unless you have a confirmed booking on a flight that is operating,” the airline said, according to the report.
Many other airlines have cancelled flights to and from Heathrow, which is the busiest in Europe, said the newspaper.
KLM, the Polish airline Lot and Brussels Airlines have cancelled their first departures of the day from Heathrow, jeopardising dozens of connections for thousands of passengers.
