Great experienced staff and very pleasant compared to some other international airlines

Flight was good and comfortable, even for long haul economy. No complaints.

Checking in via an alliance partner, even a foreign one should get TSA Precheck printed on your boarding pass. The paper copy issued by ANA didn’t show it. I couldn’t get my digital copy due to some technical issue arising because I checked in with ANA. The kiosks at SFO similarly threw an error. The only way I could have gotten a new copy of my boarding pass was from the UA counter and lines were nearly as long as TSA so I bit the bullet and went through the regular TSA line. If UA wants my business, they need to improve that process.

Suite lounge in Honolulu is very exclusive and boarding from the lounge into the plane is unique. First suites were huge and comfortable. Japanese meal is like a high end omakase meal. All the staff were very kind and provided sophisticated service. Fast Track upon landing was appreciated but not needed this time because immigration was so empty and easy.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Great first time experience on this airline. Very professional staff and great service.

Warm the bread. Movies: better choices to include Chinese movies options or some of the older winners of flim festival

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

The crew was very nice and polite. They made sure everybody got their meal and drinks. Even the economy class had a very adequate leg room for someone that is over 6 foot tall.

Purchased WiFi was slow to non functional. Staff was not personable or friendly. Seats were cramped. Boarding took long but I expected that.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Excellent - explanations were clear staff was nice and flight was comfortable

Airport in MXP is crazy. Get there at least 2 hours before flight.

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.

The flight was canceled 3 hours after original take off time

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

Flight was delayed and after being in the airport for like seven hours, it was canceled.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

Over 40 years ago my AC return flight was canceled, during this last summer the same thing happened. AC denied everything Canadian like paying for accommodations and basic necessities. So why would I ever want to fly AC again? This last flight my wife took the return flight had problems and left late, so I guess they are getting better. However I have no faith in this airline so I drove to this last destination! I'll never fly AC again!!!

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Allow me to book extra bag check in as free though I packed in 1 luggage but that was 7 LBS overweight so make another bag to free check in.

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

Boarding was so so after zone 3 was called all other zones went in

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,

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.
