Hundreds of flights across the UK have been cancelled from last Friday through to today (January 21, 2013) due to heavy snow. Airports including Southampton, East Midlands, Luton and Gatwick, which invested £8m in snow-clearing equipment, revised their schedules and cancelled flights. All flights from London City were cancelled yesterday but the airport expects to operate a normal service today. The UK experienced between five and16 cm of snow, according to the UK’s Met Office. Heathrow cancelled 260 flights yesterday and is due to cancel around half that today. A spokesperson from Heathrow announced today that the airfield was “fully operational with all runways, taxiways and stands clear”, adding that the day’s schedule has been reduced by 10 per cent “in order to cope with the low visibility conditions expected from 1600 this afternoon”. The spokesperson stated that “because Heathrow runs at almost 100 per cent capacity there is no slack in the system and flights unfortunately have to be cancelled".
