Gatwick Airport is still struggling with flight disruptions due to an issue with air traffic control which started on Wednesday evening.
The issue has been resolved but the knock-on effect has continued to cause disruptions with six flights cancelled and 39 flights delayed from 6am until midday on Thursday.
The closure of the runway has affected British Airways, Norwegian and easyjet.
Gatwick Airport said, “Flights have resumed following the earlier issue with our control tower. Apologies if you have been affected this evening.
“We plan to operate a full schedule on Thursday, however we would advise you to check your flight with your airline before setting out for the airport.”
