Appreciated the ability to get an earlier flight home after flying in from in from Japan. No problem with boarding or crew service. The limited choice of snacks, compared to previous years. Aircraft seats seem to be getting harder and more uncomfortable all the time. Overall, happy to be home

Both my wife and I thoroughly enjoyed our return home from Tokyo to Auckland and onwards to Palmerston North. We would recommend using the Premier Business class for long-haul travel, any day. Well worth the extra cost. Cabin staff were exceptional, Thank you

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.

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

Wonderful trip. Everyone from checking in to the gate to the flight itself was amazing - kind, helpful, and has a beautiful smile.

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

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

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.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .
