Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

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

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

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.

The pilot tried to make up for lost time due to delays that were out of her control. She communicated the issues openly and clearly and made every effort to do what she could to alleviate issues.

2 of the 6 economy toilets were out of order. Drinks were not offered often enough - you have to order on-screen, which is often unavailable. Snacks and Milo ran out very early. Crew was fine but I think there was a sticking issue

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.

Flight attendants are always pleasant and helpful. Pilot kept us updated.

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Excellent will be flying again in May with Qatar. to Botswana.

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

Asian Veng meal have Non Veg items which is not ok. Pure veg meals option are too less and they have inclusion of Vedgan and Lactos etc... which is taste less

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

The crew were amazing - A great job. They made me feel special and valued.

I really appreciated the fact that when I checked my bags at the Quantas counter after arriving from an international flight an hour early, the agent noticed I had a very long layover. He then found an earlier flight that allowed me to get to Cairns several hours earlier than I planned. That was amazing because I had already traveled over 20 hours and wasn’t looking forward to such a long layover. It allowed me to see my daughter and grandchildren much earlier (it had been two years since I visited last).

Qantas cancelled my flight for no good reason and rebooked me into a middle seat.

Boarding was terrible - the ground staff member Fredeya at lax was more military than customer service, have never encountered a customer service representative as rude as her. Apart from that all other staff were wonderful and the flight was good.

The flight met my expectations. It left and landed on time

My bag didn’t make it but otherwise it was a great experience.

I travelled first class from LAX to MEL and it was a series of disasters which I put down to lax staff who dont care and a suck it attitude to customers - its all lip service and no delivery. The flight was delayed due to aircraft refuellers putting on 300,000 litres of fuel on a 380Q1. I entered via the first class bridge loaded my bags in the overhead locker. the lady in the next isle in first class also had hers in there as she wasn't allocated a locker over her seat. The attendant asked would I like a champagne - I said yes please. he promptly delivered a empty glass and the glass left on the desk. Then he ignored me for 20 minutes. When i asked him is he out of champagne he gave me the usual rubbish I was distracted. There are four staff and 15 first class passengers - give me a break. the glass stayed there on takeoff and then was still there 9 hours into the flight. When I arrived to my seat I told him I had eaten and wouldn't be eating on the flight - it was 10.30pm. Yet he comes by later 4am ( I happen to be awake) and says are you eating with us? I asked for the bed to be made up - they put a 3 inch 7cm mattress on the chair but as usual the break in the chair - the mattress sinks into it - so I had to move it around so I didnt get my back sunk in the V - Im 187cm tall. The cabinet next to 1K is for staff bags and the toilet is next door. I tried to avoid this seat but couldn't change - in to the flight 8 hours and the cabin rest change over kicks in - this attendant is shining his torch in my eyes taking out and returning his bag. Then the toilet starts flushing and forget trying to get to sleep. Yet no-one else needed torch! 11 hours into the 15.5 hour flight I ask for breakfast - I order two poached eggs, bacon on multigrain toast, tomatos and mushrooms. I get no bacon or toast and have to order it and the eggs are cold. Then I order a coffee which is so badly spilled - and not by air turbulence she brings back a serviette and replaces the first one rather than providing a clean dry saucer! First class in Qantas is a joke as the staff just don't get the meaning of prompt service and attention to detail. I will fly business class rather than first on Qantas as its better value for money but I have been very impressed with United First Polaris and given I fly internationally every month this is going to be my choice.

Experience was great. My only advice is to have a pasta dish on the menu. Otherwise everything was excellent.

Flights delayed multiple times, travellers requests for updates ignored. Qantas continues to desatisfy travelling basics.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.

Wasn’t very crowded. Seamless processes. No issues traveling with two little kids.

Kayak, the site I went through to book our flight, sent very unclear emails about flight changes. Kayak was incredibly unhelpful in their communications with me about this, promising to work on resolving the issue, and failing to do so. As a result, I needed to get a hotel in Brussels and am now in the process of trying to get reimbursed. On the other hand, the flight personnel in Brussels were very helpful, taking time to look into the issue and determine if they could help. I am very grateful for them and have no problems with the airline. For Kayak, however, I will never use it again and will never recommend it to anyone, and will even discourage people who consider going through that site. My worst experience ever....

My interaction with the flight attendent Eve was horrible. I was seated in 3F and was blown away watching her repeatedly skip me as she took other customer orders for lunch...she took the customer next to me but skipped me, then took everyone's order around me (in front of and behind me) . After she had taken every customer's orders to include those behind me, she came to me and said we are out of everything except one last item. I was mortified, in that, I am a 1k flyer, had pre-ordered AND as an African American could only assume why she repeatedly skipped me...mortified. no words

The Flight was good, pilot seemed very skillful. My wheel chair sister who could barely walk was allotted the second last seat in the aircraft, with great difficulty she managed to reach on her seat, as she required attendance we were given separate seat, even on request no one cared, so much so there were single passengers who were given twin seats. May not be taken as complaint but a reminder to the checkin staff to keep in mind in future the allottment of wheel chair passengers seats.

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

Almost 2 hour delay in boarding with all standing ready to board at original time. No explanation given.
