Severe weather conditions
Heathrow Airport is not accepting any arrivals on Sunday 19 December, and is managing a handful of departures.
They are extremely sorry for the disruption this is causing to passengers. There will be further cancellations and delays tomorrow as they continue to clear snow and ice, as well as in the days that follow as airlines move diverted aircraft and crew back to their normal positions. They ask passengers to check with your airlines before travelling to the airport, and we will provide regular updates through their website and on Twitter.
This morning, they listened carefully to the advice of their airside operations team and reluctantly judged that while Heathrow's northern runway remains clear, the change in temperature overnight led to a significant build up of ice on parking stands around the planes and this requires parts of the airfield to remain closed until it is safe to move planes around.
