The flight attendances were very helpful and friendly ! Dinner and breakfast were great . The seat was not too comfortable though .

The air New Zealand employees who assisted us with wheelchair aid on Auckland made our transfer from flight to the next seamless. Also were amazing in helping with our luggage and customs in Brisbane.

New Zealand crew were attentive. We were not informed that we needed transit document to pass through New Zealand. A checkin employee helped with this for which we were thankful.

Overall good. We had to transfer to Bradly terminal. We had requested wheelchair assistance. The bus that picked us up had to wait for other passengers. The wait was long. Then, at the Bradly terminal we had to wait an extended period of time for the wheel chair assistance. These delays caused tension at checked in and resulted in arriving at the gate as passengers were boarding.

The boarding process was less than ideal. While I liked being greeted with “Kia Ora”, the rest of the process was very average for business-class travel — queue, crowding, no clear separation between economy and business premier. The aircraft felt old, even though I believe it was only 6 years’ old. Travelling in Business Premier in Air New Zealand is like sitting in a glass bowl. One can see everyone, and everyone can see others. Very bad structuring of seats. If you have a choice, fly another airlines like Singapore Airlines for business — I had the option, but chose this flight due to it’s departure time. Regrettable decision. I had opted for Vegan food choice. Very poor food as well as service. It is as if the chefs preparing the meal have little idea what nutritious, healthy and filling plant-based food is. And the crew were totally uncoordinated. In the main dinner meal, the first thing I was served was a fruit bowl, and then followed by other items. No mention was made that the fruit bowl (served first) was the dessert! And then after my meal tray was cleared another steward (not the one who served the main meal) comes around asks me that now that I had had the would like the dessert. I said yes, please. He went off and comes back to tell me discreetly that I’ve already had my dessert! He also didn’t know what the dessert was — and I guess it was the fruit platter that was the first item I was served. I was traveling with partner, who had similar experience. For her, they just cleared her table without offering dessert. Extremely poor coordination. The area behind the seats was extremely dirty. I just happened to use the overhead light to try and locate something that had fallen, only to be horrified at the dust, crumbs and all kinds of other particles. The only good thing about the flight was that when it ended, our bags came very very quickly. But that I guess is more to do with airport operations for Air New Zealands at Auckland Airport rather than the flight itself. I would think very hard next time I have to fly Business Premier in New Zealand, especially on Boeing 787-9NZM, which this plane was. Basically if you are selecting seats and find that they are at a diagonal angle, do not book this if you are looking for luxurious travel. Better off with premium economy or a good economy seat. The quality of food and service indeed was way below par.

Gate agent was fantastic in Auckland. They wanted to charge me for my two bags even though I was gold member with United in Tonga. So I had to pay for an upgrade. The meals on both flights had no vegetarian option. The only one item the salad was not tasty at all. Good thing I had brought my own snacks. The bread was white roll which is so not healthy. I think New Zealand air can definitely improve their food offering.

The entire process was excellent! The economy sits are a bit snug so I'll have to be sure to purchase premier or business class next time but, other than that, food, service, attendants were exceptional. Gate agents and ticket agents too!

Can you please process refund. Mum died and dad went to Pakistan to bury her after cancelling flight.

Short flight so no entertainment, turbulence so no food service - overall flight as expected

All was good, the only thing was it didn't run on time.

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.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

Flight departed owing to SFO TSA delays as well as incoming flight running late I know these delays are commonplace but when you’re flying long haul international the least that could be done is priority being given to customers in this situation I raced to the gate the plane was still there but NO UNITED AIRLINES STAFF in the surrounding area could seemingly provide effective support This coloured my view of flying with UA The actual flights were good

Great checkin experience and flight crew were very friendly and helpful
