Gatwick airport will close its north terminal for at least a month from April 1.
Flights will take off and depart from the south terminal between 10-2pm. Only emergency landings and diversions will be able to use the runway outside these hours.
The airport said the situation would be kept under “regular review”.
City airport closed earlier this week while services from Carlisle airport and Teesside were suspended on Tuesday. Manchester airport closed two of its three terminals on Wednesday.

Chief executive Stewart Wingate, said: “Gatwick is a resilient but also responsible business and during these extraordinary times we need to take unprecedented measures to protect the health and wellbeing of our staff and passengers, while also shielding the business from the impact of coronavirus.
“I would also like to take this opportunity to thank my staff for their continuing hard work through this difficult time and to reassure them that we are taking these difficult decisions now, so that we are in a position to recover quickly and get back to generating jobs and economic benefits for the region and wider economy well into the future.”
