Great service. Food could be improved but overall a very good airline

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

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.

The seats are feeling very hard to sit on. All the padding is flat, like sitting on a park bench for over an hour

Your entertainment could be better. I flew on Air New Zealand in January so was expecting a better choice in February...but no luck. Same choices and also could have a better selection. Otherwise, lovely service, the purser came to our seats to welcome us. Overall, very nice. Direct flight from Auckland to YVR was fantastic!

Air New Zealand over sold our flight and tried to bump us to yesterday. After several calls we got booked to United about 6 hrs before our original flight. No apologies!

Very quick flight so no time for refreshments. We took off. Then landed. The end. Seats were too tight. Very cramped Grateful for the short flight cos moving around wasn’t possible

The disembarking steps in Wellington were precarious and I felt quite insecure. There was no one on the tarmac to greet us and help. The embarking ramp in Blenheim was much more satisfactory. The rest of the flight was fine.

Entertainment screen froze and had to be reset. Noticed it happened to other passengers as well.

My flying experience was not great. The temperature was ridiculously low. I had a sweater and a big jacket and even then. Since my ticket was an economy ticket, I suppose I didn’t deserve a blanket as they were only available for business. The result, o got a cold I have not been able to shake off in 6 days which has absolutely ruined my stay in Japan as I hasn’t had the chance to leave my hotel room. Everything else that was good, had overshadowed by this. BE A LITTLE MORE HUMAN
