Air New Zealand is PROFITABLE (sustainably so and not because of write downs).
We must remember you're also talking about an airline that had to be bailed out by their Government. Air NZ would have collapsed many years ago, in an operating environment that was even more favourable for the airline. But I will again position Air NZ as operating in a favourable environment. Yes, they are a great airline. Yes, they have a good strategy and team (now). But I still argue they are in an advantageous position, thanks to many factors, not available to the likes of Australian carriers.
