Looks like the chaos at Heathrow will continue through Monday at least. Closed for all arrivals and most departures on Sunday, 12/19.....

Heathrow Airport update
Heathrow Airport will be not be accepting arrivals on Sunday, and will only manage a handful of departures as our airfield team continues to deal with the impacts of yesterday's bad weather and prepares the airport for a full re-opening on Monday.
We are extremely sorry for the disruption this will cause to passengers and airlines and we stress that passengers must check with their airline before travelling to the airport. We will provide regular updates.
In the last few minutes, we have listened carefully to the advice of our airside operations team and have reluctantly judged that while Heathrow's northern runway remains clear, the change in temperature overnight has led to a significant build up of ice on parking stands around the planes and this requires the airfield to remain closed until it is safe to move planes around.
We have 200 aircraft parking stands and have a team of several hundred people working to treat these airside areas and to keep passengers in the terminal as warm and as comfortable as possible while we do everything we can to get Heathrow moving.
We are removing 30 tonnes of snow from each stand, but the temperature remains firmly below zero and Heathrow's capacity is limited to the extent that all parking stands are occupied by aircraft, making the job of clearing and treating them more difficult.
Safety is our first priority and we hope this course of action will allow us to offer a fuller service to passengers and airlines using Heathrow tomorrow.
