Keg, can you tell me what happens if the said flight has received taxi clearance prior 2300 (as I believe was the case with another flight I was on delayed) and then a airport wide shutdown occurs for thunderstorms in the vicinity. In Sydney we all know this means nothing moves. Storm passes, oops it's past 11, sorry no go?
Or do they have enough sense to see that those aircraft were indeed ready to taxi prior to curfew? If not then a severe weather policy is definitely needed and all those NIMBYS can go buy some
earplugs!!
