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!
For what purpose do you wish to know this information.
(Sounds like a journo question)
