A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

Flight was delayed by 2 hours. Got lucky that i had a long connection, else would have certainly missed my connecting flight. Food is just okay, specially the breakfast is worse . Asked for water 30 mins before landing, the response is that we are landing so everything is packed . I guess traveling in economy that’s what we get. Probably business class passengers would get a different answer. Only good thing is that wifi service is available from auckland to lax for most part Next time will try united or American and then compare.

I was trying to get confirmation on if my luggage was going to be moved to the earlier flight (I requested standby to get home earlier) and was unable to get help from those working at the counter. The request to be moved to an earlier flight was handled smoothly through the app and appreciate the ease of the request.

Our original flight was cancelled from SFO to AKL on 6/16/25. So we had to stay overnight at a hotel after a 12-hour layover plus 3-hour delay before the cancellation. Then had to fly to LA and then to AKL the following day losing an entire day of our vacation in NZ, that we can never get back.

Great! Flight was delayed by 30 mins but all was great. Thanks.

Economy was much nicer on the Air New Zealand planes.

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 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.

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

So here's the rub - my flight was booked through Chatdeal even though I bought it under the Kayak umbrella. All the return flights were theoretically through Air New Zealand, however except for the initial leg from New Zealand, they were all partnered flights. So when I arrived at the airport in New Zealand they could only issue me my ticket to Fiji. Once in Fiji I had to do some serious leg work and finagling to get my ticket to Los Angeles through Fiji Air. This included a monitored covid RAT that I wasn't aware I needed to do. So I gave the score I did because of the complexity and annoyance created in the process of getting a boarding pass for my Nadi-LA flight.
