Further snow travel chaos set to disrupt Christmas week
Thousands of people face further disruption to their Christmas travel plans as cold weather conditions continue to grip much of the country.
British Airways is hoping that about 60 flights will depart Heathrow on Monday morning, but dozens of cancellations have been announced.
Hundreds of travellers slept there for a second night, amid mounting anger.
Gatwick, Stansted, Edinburgh and Southampton airports are open but expect delays or cancellations.
Meanwhile, the Met Office has warned of more snow and ice in many parts of the country.
A "bitterly cold" day is forecast, with freezing fog.
Southern England and south Wales were among those in the "firing line" for Monday, said BBC weather forecaster Helen Willetts, with 5-10cm of snowfall that could coincide with both the morning and evening rush hours.
There were also warnings of more heavy snow for much of Scotland and north-east England, with up to 10cm of snow expected in northern Scotland.
The lowest UK temperature overnight, recorded in Chesham, Buckinghamshire, was thought to be -19.6C.
Thousands of people had stayed at Heathrow overnight on Saturday, and few flights departed on Sunday, when some 210,000 people had been due to fly.
Airport operator BAA said further cancellations and delays at Heathrow would be inevitable.
It added that beyond Monday there would be continued problems "as airlines move diverted aircraft and crew back to their normal positions".
The BBC's Asha Tanna said: "Airline bosses have been meeting to discuss how many flights will be able to operate once the weather improves but with forecasters predicting further snow and freezing fog passengers are now being advised not to travel and to cancel their trips and get a full refund instead."
On the railways there was some disruption on Sunday, including the suspension of East Coast Train services between London and Peterborough, stranding hundreds of passengers.
No trains were running between Oxford and Hereford, while some Chiltern Railways, South West Trains and First Capital Connect services were affected by the weather.
With France also suffering severe weather, Eurostar said people should not travel unless it is necessary.
It also said speed restrictions and delays were expected.
The Foreign Office has updated its travel advice for France, warning of disruption to road, rail and air travel in the country.
Elsewhere in Europe there were severe disruptions at airports in Frankfurt, Paris, Florence, and Amsterdam.
Stansted, Luton, Exeter, London City, Birmingham, Bristol and Southampton airports said flights would be subject to delays and cancellations.
