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

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

I was not even on that flight and did not even book a ticket. Kayak did a phenomenal job

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

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.

Good and appreciate the effort Air Zealand puts into using more environmentally friendly food containers and utensils. yay! One of the better airlines for this for sure. Still some bad stuff, but at least Air NZ is trying. :) Also really enjoyed the bluetooth option for personal headsets. :)

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.

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.
