Thousands of passengers are facing a second day of disruption as fog continues to force the cancellation of flights in and out of London. Heathrow Airport and London City Airport, which were disrupted throughout Sunday, are affected. By 06:55 GMT, 37 arrivals and 22 departure flights from Heathrow had been cancelled. Ten flights due to depart from London City had also been cancelled because of the weather. The foggy conditions were expected to lift by about 10:00 GMT, the BBC weather centre said. Heathrow Airport, which deals with an average of 1,300 flights a day, said passengers should check with their airlines before travelling. Heathrow said 132 flights, including 50 BA flights, were cancelled on Sunday due to heavy fog. A total of 58 incoming flights were cancelled. 'Difficult' conditions Some airlines were re-booking passengers on other flights, while others were arranging for accommodation. Some domestic passengers were being taken to their destinations by coaches, the airport said. Heathrow Airport is open, but air traffic controllers have slowed the rate at which aircraft can land. London City Airport suspended up to 44 flights on Sunday and delayed others because of "low visibility". BBC Weather forecaster Holly Green said: "The Met Office are warning the fog may cause further travel problems, particularly during Monday morning rush hour." Matt Rigby, from London, spent the day at Heathrow having seen his midday flight to Moscow delayed and then cancelled. He said: "Staff did not know what to do and gave conflicting advice. "There were lots of other people standing around in queues back in the terminal in the same situation. It was all pretty chaotic." Mr Rigby said: "We weren't even told it was due to fog, but I was able to figure it our for myself because it was pretty foggy out there." A Gatwick Airport spokesman said it had low visibility and had a couple of delays, but on the whole it was business as usual. Driving conditions could be "difficult" and motorists have been advised to take extra care. A weather warning for dense fog also has been issued for Yorkshire and Humberside, the East and West Midlands, the East of England and the South East. Fog has also affected large parts of Germany, the Netherlands and Belgium.
