I know a couple of people who have flown on it and regard it as a vastly superior hard and soft product offering compared to Air NZ. Staff on the other hand seem to be very mixed (but we can also say that about NZ as well).
It'll be very interesting to see what regular NZ FF's think of the product once it starts here, and if NZ were smart they'd be pulling the details of NZ FF's who fly on it and start questioning them about what they like and dislike about it so they can further plan for their new BP seat.
