Heathrow's Terminal 5 has been left almost entirely empty after British Airways cancelled 80 short-haul flights as Britain suffers what forecasters have predicted will be the coldest week of the winter so far.
Snow is predicted to fall across the majority of the UK tonight as the country prepares for the freezing weather.
Temperatures have fallen as low as -13.7C in the Highlands and are forecast to be similarly icy tonight.
Meanwhile British Airways has left passengers stranded and out of pocket after cancelling the flights out of London Heathrow as the capital is set to be hit by a flurry of snow.
The Met Office has warned this week could be the coldest of the winter, with many waking today to a blanket of snow.
There was heavy snowfall and ice across much of the UK as temperatures overnight fell to -6C in Katesbridge, Northern Ireland, -4.7C in Loch Glascarnoch, Scotland and around -3 across southern England and London.
Drivers suffered the consequences of the poor conditions in Kent, with five multiple-vehicle collisions involving 15 cars between junction 8 and 9 of the M20 last night.
Excited Londoners shared pictures of snow flurries across the capital this morning, with snow fall across Greenwich, the Royal Victoria Docks and Clapham.
But Met Office meteorologist Alex Burkill has now warned temperatures could plunge as low as -14C in Scotland and the north and -4C in London overnight on Tuesday, with freezing temperatures across the UK into Wednesday.
The biting cold is likely to remain throughout February, according to Mr Burkill, with below average temperatures dipping below zero.

Mr Snell said the working week would start on a 'bitterly cold' note, with the bulk of the population waking up to temperatures between 0C to -2C.
He said: 'It's going to be a cold week, plenty of dry weather around, but many places will probably see some snow at some point during the week, but for a lot of us not really amounting to much at all.
'Probably one of our coldest weeks of this winter so far, but snow-fall wise, doesn't really look too disruptive at this stage.'
The mercury could plummet as low as -7C in sheltered parts of Scotland and spots most prone to the cold in the Midlands and Wales on Monday.
A snow and ice weather warning has been issued for Wales, Northern Ireland, most of Scotland and northern England, beginning on Monday night from 8pm and continuing until 3pm on Tuesday.

Then, between 9pm today and 3pm on Tuesday, there is a further chance of snow and ice for the north of England, northern Ireland, north Wales and Scotland.

'So many people will see some snow but don't expect to build a snowman.'
