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??

Everything very good except the sofa couch not as comfortable as expected.

Liked the non-stop option, can always use more leg room!

Wonderful Airlines…our American Airlines could learn from ANZ. From boarding to landing everyone was professional and gracious. Kiwi’s really are the nicest of all people! Thank you

typical long haul economy flight. Food was mediocre, inflight service was average. Offered in flight snacks but in seat ordering didn't work. Entertainment was good.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.
