As an NZ Gold frequent flyer, who usually flies in business premier or premium economy, it is an interesting proposition. If travelling as a couple I’d seriously consider this over premium economy. Given most NZ long haul flights are overnight, I would have thought it would be a serious option for couples.
The premium economy product is getting up with the best too, with a 2-2-2 configuration on a 77W, this is looking a lot closer to business class of not too long ago. It will be particularly interesting to see the reaction on the highly competitive LAX-LHR route as NZ will be light years ahead of BA and VS, let alone UA, AA and DL.
