Think you'll find that most major airport runway upgrade work will take place over autumn/winter months.Between the summer schedules finishing and starting the following year. As Vampy says, during the summer schedules Easyjet, Ryanair and holiday charters operate into the early hours of the morning, whereas during the winter most flying has ceased by 23.30 anyway.
Airline Ops have had plenty of notice of this and months of planning has gone into it. All of the work has been NOTAM'd well in advance.
To blame airport management for one day of poor weather affecting operations is naive in the extreme. The result of the work being completed in the spring will greatly benefit the airport and airlines.
