I love the “boarding from the back” idea - it’s so much better than the “Zones” idea that many others use. Also, the inflight wifi was a first for me! Very nice to have on a 13-hour flight!

I love the “boarding from the back” idea - it’s so much better than the “Zones” idea that many others use. Also, the inflight wifi was a first for me! Very nice to have on a 13-hour flight!

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

The issue was with getting our boarding pases. There were issues with our arrangements that were made through Kayak. I am sorry to say that we will not use you again because of this. The flight itself was good and the flight attendants excellent.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

USB charging ports did not work on any of Air New Zealand flights

Everything was fine. Wish the wifi was free and included in the ticket price.

Nothing special short flight - all good - difference between 1 fudge and 2 fudge is obligation and thankfulness

The flight we had booked was cancelled due to bad weather conditions, but we were lucky to arrive at the airport quite early and got a seat on an earlier flight. The flight was mostly nice, but there were some hefty turbulences towards Queenstown. One of the passengers behaved hysterically. It would have been great if the crew had done something to calm her.

Major hassle with the weight of carryon luggage Having to repack bags at airport Not an issue in most of world Ridiculous issue considering the 400 pound gentleman sitting behind us

Overall experience was poor. In general crew was polite in speaking but that was all about it. I am vegetarian so I always carry a cup noodle box with me just in case. So I pressed "CALL" button for hot water for my cup noodle on my seat and waited for 10-15 minutes but nobody came. I personally took the box and went all the way to back of the plane. When I requested stewardess to put hot water in my cup noodle she refused as it was a "safety" hazard. I told her that you always serve coffee and tea these are also hot. But she still refused. I went back to my seat and from the seat I ordered hot water and it was brought to me without any problem. I poured THAT hot water in my cup noodle and ate. I was sitting in seat 36A, which was 2nd row in economy class. After eating my noodle I took the box and went 2 rows in the front where there was a kitchen to throw it. Again the stewardess there told me she didn't have a waste bin there and asked me to go back of the plane and throw it there. Tell me if above experiences are 'ok' for your airline??
