I wish there were more bathrooms available on these larger carriers.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

The morning in Hong Kong was ridiculous. Very chaotic. The flight was delayed. Missed connecting flights. Kathy should be more competent in getting the planes ready ahead of time so that flights can depart on time.. totally ridiculous and unnecessary. Very poor performance.

Flew from lax economy on cathay 777. Seat configuration 3-4-3. When the forward seat reclines it feels like someone is leaning forward and staring you. If you are slightly big tray tables will touch your abdomen even with seats upright. AVOID this above 777 configuration at all cost for a long flight. However their Airbus 350 3-3-3 configuration felt spacious and Seats wider.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

Crew on this flight dedicate their business class service to their high priority members. They would get priority service even the seats are behind me, and meals priority service and orders. I get the left over choices. I refused to eat because I felt discriminated, never booking this airline.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

United have really come back. Airport and boarding process is clear and good, app and information also very good

They charged a fee for 1st bag checked. Others in same party were free.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.
