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.

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.

Overall the plane was good and the crew great. The big disappointment was the skycouch. Maybe it would be good if you were a parent with 2 small kids travelling but as a couple it's hopeless. It's impossible for 2 adults to lie down so one ends up sitting. We split our time with one lying and the other sitting. We both got more sleep sitting upright. We will never book one again and don't recommend it to anyone.

Not entirely positive. It’s frustrating that everything is done through the united app. One of our flight attendants on our trip from San Francisco to MSP continually had trouble hearing people so she flipped her hair into people’s faces

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.

Everything very good except the sofa couch not as comfortable as expected.

New Zealand crew were attentive. We were not informed that we needed transit document to pass through New Zealand. A checkin employee helped with this for which we were thankful.

All was good, the only thing was it didn't run on time.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

There was a loud squeaky sound the whole time we were flying.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

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.

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Smooth flight. As always dinner could have been more generous. Breakfast was great.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Great checkin experience and flight crew were very friendly and helpful

Staff did not care, and very clearly did not want to be serving passengers. Requests were ignored repeatedly. Toilets filthy. Bins were just trash bags hung around the place that were never emptied. It was a challenge to even get a glass of water on a 14 hour flight.

Flight was diverted to Canberra because Not enough fuel to circle on Sydney’s skies waiting for showers to pass. After that everything went wrong. It took forever to put fuel. Once back rolling, we stopped short of takeoff because crew had reached maximum work hours per shift. Back to gate we waited and waited in the plane with no water and no food - a total of 4 hours. Received contrasting news about the follow up of our trip. Finally we disembarked but our luggage could not be processed there as not enough custom agents. We ended up on buses and arrived at Sydney airports after a 3 hours trip. There we had to queue in line with 240 more passengers to file a lost luggage claim. We received the luggage after 48 hours, many of which spent holding with non-existent United customer service. Never able to speak to an actual person during those long phone calls. Finally on a chatline I could talk to a baggage agent, who filed another report as our luggage did not appear anywhere in their system. Thus it was surprising to get it back.

United requires seat selection in order for those booking together to stay together.

I was traveling alone abroad for the first time and the staff was not helpful and rude at times.

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

Baggage allowances are terrible and the experience of only being allowed one bag and paying so much to take sporting equipment to a known ski area should be addressed.

The entertainment package was vast and the selections were very current. Keep updating it was great.

The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.

Bad food, small seats that didn’t recline. I thought I was buying a quantas ticket so I feel like I got scammed

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The food at Admirals Club was really great Pijamas were a nice feature The flight attendant was very nice and great attitude The aa.com does not work well specially internet service Overall a very good flight .

Flight a little late. Entertainment system didn’t work for first hour. Toilets dirty after 2 hours. Is there no one assigned to clean them?

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

Not enough electronic outlets for charging in the Air Canada waiting to board area but the Most important thing….the plane was booked to only 40% capacity and my row of 2 other seats were empty. My row happened to be one of the few rows that did NOT have raising arm rests. The flight attendant made effort to seat me in a different row. I needed wheelchair assistance due to a cyst on my knee and struggled to move from seat to seat to get to the row. Those 2 empty seats tormented me the entire 15+ hour flight as I had to be upright the entire flight and was not able to elevate my knee. Lots of other passengers were laying down due to the arm rest being able to retract. It is a shame that he couldn’t be gracious and find a row that I could move to.

Terrible. My brother broke his leg and couldn’t board the flight and air Canada couldn’t do anything about rescheduling his flight. Poor customer service and help all around

I Teall staff was great and helpful and communicated needs and special care for my granddaughters and family as well as others. Well done

Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Flight delayed 3 times and also delayed again and by the time I reached Sydney, I couldn't get my Virgin Air as my flight was delayed and I was asked to contact here and there and asked to go to this and that terminal and was told there's no other flight as flights are all full to Melbourne. Thank God, at the very last minute, I was put into Qantas and didn't arrive till 7.30 pm in Melbourne instead of 2 pm. Will never use Air Canada again. Besides, the sittings is so tight and can hardly stretch a bit and eat without elbowing my side passengers. It was indeed a very uncomfortable flight.

Crew helped to find more comfortable seats for passengers. We never got tea or coffee on this trip even when we asked. Not even with breakfast.

I could feel the knees of the person behind me in my lower back for 15 1/2 hours. The. Seats were small and space was tight. People were nice. Coffee in the morning was in a small cup and half full and they never came around again.

THEY LOST MY BAGS. I WILL NOT GET THEM BACK FOR 2 WEEKS. everything was delayed. boarding, take off, everything. it was horrible. i am now without luggage for 2 weeks and they have offered me 0 compensation or help. i will NEVER fly air canada again and i suggest you don’t either <3
