Thousands of Christmas travellers are still having a hard time as widespread snow and ice continue to cause problems across the UK.
Weather experts say more snow's on the way for parts of England, Scotland, Northern Ireland and Wales and it's unlikely to warm up for several days.
Hundreds of flights have been cancelled or delayed as icy conditions forced the UK's main airports to close.
There are also major delays on the trains and several road closures.
Europe has also been badly affected by the wintry conditions
In Northern Ireland and parts of northern England, temperatures dropped as low as -17 degrees on Monday night.
At Gatwick airport, near London, people have been working through the night to try to clear its runways so more flights can take off.
But passengers are being warned to expect delays and cancellations, possibly until Christmas Day.
Europe is also suffering in the latest wintry weather, with France and Germany both suffering similar disruptions to roads, trains and planes.
