I will no longer fly Air NZ if it involves a 777 300 (and soon the 777 200 which are being retrofitted).
The comfort, space and ease of use of the economy seat are non existent and this is probably the worst aircraft I have ever flown on. The “cuddle class” seat is a joke and might just fit two vertically challenged children but not any adult I know. Air NZ have become greedy and only care about their business and premium economy passengers. Do not use this air line if you have to fly economy class, you WILL regret it.
