I remember Geoff Dixon at the meeting with the AIPA pilot members talking about numerous aircraft types.
His take on the subject was that Ansett did not do it with anything in plan and no real thought.
In Qantas's case the aircraft chosen were the most cost effective for the routes, cheapest to operate and best deals obtained in procurement.
All three of the above did not relate to AN.
Besides, Mr Airbus must have a very raw backside after signing the deal for A320's with Jet Star!
