Rail and air disruption continues amid plunging temperatures
Business travellers face another day of misery on trains and at airports as freezing conditions continue to cause major disruption.
Network Rail has confirmed that scores of services across the UK have been cancelled while others face severe delays.
Customers have been urged to check the status of trains on operator websites before attempting to travel to stations.
Alternatively, National Rail Enquiries has set up a dedicated telephone hotline - 08453 017641 - to provide updated information.
British Airways has cancelled flights at both Heathrow and Gatwick and has warned that other flights face severe delays.
Easyjet has also grounded nearly 70 flights, most originating from Gatwick.
Elsewhere in the Greater London area there has been disruption at Luton, Stansted and London City airport.
There was better news at Manchester Airport where the operator hoped to run a normal service all day.
A statement on its website said: "No further snow has fallen since that of the early hours of Tuesday morning and the majority of flights cancelled due to adverse weather on Monday have been cleared.
"The forecasts for the Greater Manchester area indicate a slight possibility of a small amount of snowfall overnight; however Manchester Airport's operations are unlikely to be significantly affected.
Meanwhile, bosses at Liverpool John Lennon airport advised customers due to travel today to contact airlines directly.
Cardiff and Bristol airports and those across Scotland also face major disruption.
