When do London airports close completely for maintenanceor any other reason?
Hello,
I know that some airports, such as Tel Aviv's, close once a month for only a few hours (usually in the late evening on Fridays) for maintenance works at the airport. That's when flights can't depart or land - the airport is basically shut and doesn't operate (about 4 hours once a month). Obviously flights that are supposed to depart or land during these hours are cancelled/rescheduled. The notice is about these are through NOTAM (Notices to Airmen).
Is there such a things at any of London's airports?
Thanks!
