YUP!!! I've seen better organisation in Port Morbid, truly.
One day last week, we missed our slot by 14 mins (whilst waiting for a tug).
We called up on ground for pushback and they said "you've missed your slot time - the next available is 40-50 mins from now". Our response was "ahh no i'm sorry we were given XXX slot on Clearance Delivery".... suckers!
Do they not realise they have 2 runways??
Also what's with the new rule where you cannot call up for a slot until 30 mins before??
Just one more thing you have to choreograph on a turnaround. Make the place a f***ing CTAF and be done with it.
