Just had an isle seat (centre) from Auckland to LAX... how uncomfortable... being seated on an angle when you really want to be sat straight, I'm tall 6'1-2 and not getting to somewhat stretch when seated.. similar when I get a bulk head :/ Uncomfortable too when the screen folds out and is pretty close to your face! hah
Though, I cannot fault the service on AirNZ... they were great!!
Three sectors were in the normal PE seats... and one was the Spaceseat.. it did look great in photos but not really practical.
