The Air New Zealand product is terrible, it's as expensive as a Jetstar ticket with add ons but with surely staff and old aircraft.

The Air New Zealand product is terrible, it's as expensive as a Jetstar ticket with add ons but with surely staff and old aircraft.

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.

Space between seats on Air New Zealand is generally tight. The crew on this flight was excellent! Very attentive and nice. You get free wine or beer and chips and of course the Air New Zealand candies. 1 hour and 35 min flight approximately.

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

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!

The food was not as good as Air New Zealand. The veg pasta was pass-able but the veg cibotta sandwich was dry, hard and not up to par. The coach staff were attentive and accommodating.

Air conditioning was turned to the wrong setting. Way too hot. The entertainment system kept resetting and didn’t work half the flight. Said something to the crew. They didn’t do anything to help. Plane had a mechanical problem that resulted in 2.5 hour delay. Boarded the plane, had to disembark and get back on.

They are my favourite airline in the world by a million miles.

Do the bumpy weather the whole trip they were very few times when the seatbelt sign wasn't on
