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.

Flight restrictions remain in place at Gatwick Airport for a fourth day because of fog, disrupting travel plans for thousands of passengers. More than 20 flights planned for the West Sussex airport on Monday were cancelled in advance and passengers are being warned of delays throughout the day.

It follows two days of disruption at the UK’s busiest airports, with Saturday’s flights at Stansted Airport affected by the murky conditions, while live departure boards showed delays at Heathrow, Luton, Gatwick and Manchester Airports.
