PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

Much better than I expected for such a long flight.

Good - better than other airlines in terms of food and seat comfort.

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

Flight LA to Sydney was first moved earlier by 2 hrs from 10:25 pm to 8:25pm roughly a week before departure. Then on actual departure date, it was delayed 2x, and needed up leaving close to 10 pm. Then entertainment for the whole flight wasn’t working for most of the seats including ours. The baby crib at the middle isle was being taped to the wall to keep it tacked in using a packing tape while passengers were walking by looking for their seats. Not projecting good confidence. After a few minutes after take off the whole crib fell off. Good the people seating next to it wast hit or got scared. At arrival at Sydney, crew handed the customs forms as we were getting out of the plane. So passengers had to scramble to find a place to fill up the forms along the corridor going to immigration. So no one is available to help from Qantas to fill up the entry forms. Not a very good experience for a flagship carrier.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

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.

Got automatically assigned a middle seat, unless I fork out extra money for seat assigment.
