Heard out of CHC recently.
Controller: Qantas xx Flxxx no longer available.
Qantas xx: Considering our preflight request and faster aeroplane shouldn't we have preference?
Controller: I don't know the rules.
Air New Zealand: What was thet? Iz thet Warren?
Qantas: I haven't had a laugh for a while, say "fish and chips or better still would you like to buy a vowel (aka Wheel of Fortune)"
