Snowfalls took the capital by surprise at the weekend and caused chaos with airline scheduling with hundreds of Heathrow cancellations, particularly among domestic and short-haul flights.

A BA spokesperson said: “We are operating a near normal schedule today but continue to offer customers, who no longer wish to fly to or from Heathrow today the chance to have a full refund, regardless of whether their flight is cancelled or not.”

BA declined to confirm the number of cancellations. Asked if reports of 100-plus were true, the spokesperson commented: “I don’t think it would be that high.”

Snow also affected northern Europe, meaning that some flights that did take off were then diverted away from their destination.

The spokesperson added that passengers who did not wish to travel on Tuesday would be booked on alternative flights due to depart until December 18 and that BA would use partner carriers to accommodate all passengers.

BA customers who have had their flight cancelled can rebook to travel up to 14 days after the date of their original booking, although the airline says this is “subject to availability”.
