London's Heathrow airport said dozens of flights had been scrapped, reports Efe news.
At Edinburgh Airport, three British Airways services to Heathrow were cancelled, along with two KLM flights to Amsterdam, an Easyjet service to the Dutch city, and a Flybe flight to Shetland.
British Airways was inundated with messages from unhappy customers on social media, who complained of long waits on the tarmac and no response on their customer service phone line.
Meanwhile, long-haul inbound flights from Dubai, Mumbai and NY landed at Paris, Frankfurt and Dublin respectively, the Independent reported.
A number of flights from the United Kingdom to Ireland have been cancelled because of snow.
Others posted pictures of huge queues waiting for flights.. "We're sorry for the problems and inconvenience caused by the disruption".
The extent of the disruption, which saw up to 32cm of snow fall in parts of Wales and led to Birmingham and Luton airports temporary closing their runways, meant that a British Airways flight to Heathrow scheduled for tomorrow morning has also been cancelled. "As a result of the forecast of continued bad weather we have agreed with Heathrow Airport, National Air Traffic Services (NATS) and other airlines to reduce our flight schedule from Heathrow on Monday December 11".
Due to the ongoing disruption, airports have advised passengers to check with their airlines prior to setting off.
"The safety and comfort of our passengers is always our first priority and we are working closely with our airlines to ensure affected passengers are looked after".
"Heavy snowfall: do not come to the airport until further notice", the airport said on Twitter, adding that passengers should check the status of their flights. "We apologise to those affected by today's weather".
