Great airline service by the staff. I highly recommend it

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.

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

Again, Air New Zealand was great. They kept bathrooms clean, food was actually very good, New Zealand wines a big hit

At Coolangatta International it is difficult to hear voice boarding announcements when away from screen announcements.

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.

Overall excellent but the Captain kept the seat belt sign on for far too long, especially at the beginning and end of the flight. It was 2 hours after take-off before the crew were able to start the service (on an 11 hour night flight, reducing our sleeping time) and the seat belt sign on went on during breakfast (90 mins before landing) and was not turned off again until we landed. This made for an uncomfortable journey of trying to limit fluid intake because it was unclear when the toilets would be available for use.

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

The pilot tried to make up for lost time due to delays that were out of her control. She communicated the issues openly and clearly and made every effort to do what she could to alleviate issues.
