Disruption is continuing at Gatwick Airport for a fourth day after heavy fog affected flights in one of the busiest periods of the year. Some restrictions due to adverse weather remain in place, the airport said.

Flights to everywhere from Belfast and Tenerife to Kraków, Poland, and Accra, Ghana, have been delayed by as much as an hour and a half this morning. Live arrivals boards also show slight delays to incoming flights. According to the monitoring website FlightStats, the delays are ‘excessive and increasing’.

Tens of thousands of passengers have had their Christmas travel disrupted in recent days as thick fog has descended on airports.
