Great airline service by the staff. I highly recommend it

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

Boarded on time, smooth flight and "gentle" landing in Palmerston North. Ahead of time due to a tailwind

Appreciated the ability to get an earlier flight home after flying in from in from Japan. No problem with boarding or crew service. The limited choice of snacks, compared to previous years. Aircraft seats seem to be getting harder and more uncomfortable all the time. Overall, happy to be home

Both my wife and I thoroughly enjoyed our return home from Tokyo to Auckland and onwards to Palmerston North. We would recommend using the Premier Business class for long-haul travel, any day. Well worth the extra cost. Cabin staff were exceptional, Thank you

Wonderful trip. Everyone from checking in to the gate to the flight itself was amazing - kind, helpful, and has a beautiful smile.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

Nothing better than Air New Zealand. Top scores in every category.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

All good, except entertainment system could have been better. More choices.
