According to SkyTrax. Premium Economy still won an Award.
I'd agree with this. A couple of years after Rob Fyfe took the CEO job, AIR NZ was our favourite airline, having a fantastic product, excellent staff and a general willingness to help if things weren't right. They were flexible and accomodating.
Now they are none of those things in my experience.
Their reward program is horrible too. Bidding for your seats is a stupid idea.
