Teesside and County Durham hit by freezing temperatures
Travellers are facing continued disruption across Wearside, Teesside and County Durham because of snow and sub-zero temperatures.
Durham Tees Valley Airport near Darlington was closed for a third day.
Travellers due to fly over the next few days are being urged to contact tour operators as flights may take off from other airports.
More than 120 schools were shut as well as some roads, including the A66 at Brough.
A spokesman for Durham Tees Valley Airport said: "If you are due to fly over the next couple of days, please contact your airline or tour operator for information as they may arrange diverts, reschedule or cancel the flight."
Bus and rail passengers also faced problems with delays and cancellations.
Some outlying areas saw temperatures dip to -12C, with forecasts predicting them to remain below freezing.
Teesdale and Weardale Mountain Rescue Team was called in to help two district nurses attempting to get to a patient in a remote farmhouse in Stanhope, County Durham.
A paramedic in a four wheel drive vehicle had earlier been unable to get near the property because of drifting snow so the North East Ambulance Service asked the team for assistance.
