No doubt ANZ have scored a big discount here to get the airbus'. It makes sense though, as it is just not sensible to have a short/medium haul fleet of more than one type. Only option here was to either go all airbus or all boeing. Interesting though as when Jetstar started domestic ops in NZ with the A320 the post was full of negative comments saying that the A320 just doesn't work as a shorthaul aircraft, especially on thin routes like in NZ and that ANZ would only ever run the boeing because of this fact!!
As for the comment about the crashed A320, what a rediculous thing to say. If you really want to know 'what happened' there then I seriously suggest a bit of research, all the information is out in the open. I think you will find the loss had not a lot to do with aircraft issues and more to do with airmanship choices made on the day. Bloody insenitive and not at all relevant
