Four British Airways flights headed for Heathrow had to be diverted to Newcastle, 300 miles away.
Heathrow Airport also stated: "Some flights at Heathrow will be disrupted today due to crew and aircraft being out of position following yesterday's weather".
This follows the cancellation of more than 160 flights at Heathrow Airport yesterday and more than 60 today, which is said to translate into between 13,000 to 15,000 passengers.
At least three airports, Stansted in central London, Luton located some 30 miles north of the British capital, and Birmingham Airport were closed earlier in the day, while their runways were cleared of snow. Six morning flights from Glasgow and Edinburgh have been cancelled. The company said average delays are five hours, yet Twitter users have claimed delays are much longer. We apologise for any inconvenience but safety is our number one priority.
"We're very sorry that some of our customers' travel plans have been affected by severe adverse weather conditions", a British Airways representative told The Independent.
The widespread disruption follows heavy snowfall, rain and gale force winds in parts of Great Britain. Our teams are working hard to get flights in/out as soon as they can and we will keep this website up to date with latest information.
