ATC IssuesA place where pilots may enter the 'lions den' that is Air Traffic Control in complete safety and find out the answers to all those obscure topics which you always wanted to know the answer to but were afraid to ask.
Try the UK AIP which gives opening hours for all licensed airfields. Most of the bigger airports are H24 all year, but I'm not sure about the smaller ones.
Thanks for the reference, I'm sure there used to be a NOTAM or other notification issued around this time which confirmed opening hours/limitations for Xmas.
