The Met Office has said cold and icy conditions could last into next week, with some areas under weather warnings until Monday and travel services still disrupted this morning.
More than 4,000 flights have been cancelled since the ‘Beast from the East’ began bringing snow and ice across Europe.
Glasgow, Edinburgh and Leeds Bradford airports said they planned to re-opened today, but warned that some airlines had chosen to cancel flights as a precaution. Meanwhile, Dublin airport has suspended all flights until Saturday.
Several other airports are experiencing delays and cancellations, and while they remain open, some airlines have decided to cancel flights. Passengers are advised to check before they travel.
National Rail says it has been working overnight to keep tracks clear, but operators in some areas are advising passengers not to travel unless necessary.
Virgin Trains will not run any services north of Newcastle today, with its route between Carlisle and Scotland closed and no replacement bus services running. Likewise, Scotrail will not operate any trains within the amber weather warning area until later today and no Crosscountry services will run in Scotland either.
Great Western says it will run a limited service today, while the Heathrow Express is operating less frequently from Paddington station, which is now open following a closure yesterday due to hazardous conditions in the station concourse.
Dangerous conditions on roads across the country are making journeys slow or impossible for drivers, with routes in the south west closed overnight due to accidents and abandoned vehicles.
With more snow expected today, travellers should prepare for delays to their journeys.
