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.

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.

Sitting in an aisle seat equals getting hit by food cart and spilled on multiple times Food: gross and minimalistic Crew: frumpy and kurt Sound on multiple entertainment platforms poor Not an earplug problem, system soundboard poor

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.

Would have been nice to have decaf coffee as an option, and perhaps a scone

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.

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight delayed over 2 hours . I was flying bussiness never got food cause they ran out of what i wanted

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.
