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.

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

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 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.

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.

They were fast and I like how they used to entertainment system to play video about the safety.

Flight delayed. Connecting to night flight was stressful but made it. Jusr in time. Ran.88Flight was fine.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

Delayed by 5+ hours and they give a voucher for only $20 CAD which isn’t even redeemable at any place with edible food. Then took almost an hour to clean craft after it landed. And nonsensical boarding delayed even further. We didn’t leave until 1:30am….

The flight was delayed, but not for weather. We landed over 3hrs later than planned.

The stag were helpful, kind and liked the passengers. The plane was pristinely clean! Great flight!

My flight was delayed more than once, but Air Canada updated us regularly. Friends on other airlines had much worse experiences.

By modern air travel standards, our 15-hour flight to Delhi was very nice. Quiet-ish, straightforward, good service, okay seats, etc. All good.

Again, it was delayed and then our connecting aircraft was very cold.

It was very cold in the beginning; then I asked stewardess to do something about that, and she did something, so for the rest of the flight the temperature was closer to normal. It is typical: by some reason the pilots or whoever is in charge make the cod in the cabin unbearable. The seat is better than on WestJet or Flair, but is is very tight. No leg room.

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.
