Meanwhile, more than 80 flights to UK airports were forced to divert to continental airports on Monday, according to analysis from Flightradar24, the plane-tracking site.
Travellers were scattered as far afield as Germany and the south of France as airliners diverted away from Britain in search of calmer airports.
The longest diversion was a Jet2 flight between Gran Canaria and Belfast. Its pilots orbited the Northern Irish capital before setting course to Paris, where they made a safe landing away from the bad weather.
Steve Fox, head of network operations at air traffic control company Nats, said on Sunday there were more than “100 go-arounds at airports across the country and we still don’t have a total on the number of diversions”.
Go-arounds are when an airliner’s pilots abandon a landing attempt because conditions are not safe enough to try and touch down.
