It is down to the Airport Authority although we have a little operational leeway, but I wasn't talking about the runway closure itself, that's nowt to do with Servis-scare.
And the extension on Tuesday was granted by the Airport Authority as a favour to the airline concerned for other reasons and it was only for one flight outbound. I haven't mentioned Wednesday cos I wasn't at work. Perhaps they redeemed themselves on Weds, but I'm sure it was before 2300, doubtful it would have been later.
