Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

Check in process in Manila was so slow. From the time we got in line to reaching the counter we could have arrived at Taipei even if the flight was delayed for half hour.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Except for crying babies all was ok although the movie selection wasn't the best.

Good. Please add a non- applicable category to your questions.

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

EVA air was nice. It was the first time I’ve flown with them. The poor entertainment choices for 2 long flights will make me think about choosing them next time. I didn’t know if would effect me so much but I couldn’t sleep and it added to the stress. The food was terrible for me but I couldn’t find how to inform them about my diet when I bought my ticket.

Flight from New Delhi to Tokyo was mediocre. The seats were not of business class as we are used to. They were not wide enough. On the other hand the seats on the flight from Tokyo to San Francisco were excellent every thing were great except the food. Tokyo business lounge was excellent. The whole experience was great except the food on the plane. Will still fly JAL.

The entree wasn’t very good. The rice was soggy. The side dishes were all good though. The breakfast was also good. The crew were excellent, as usual.

The flight attendants were excellent as usual however the meal wasn’t the usual good quality. There is cooked rice was mushy.

This portion of the trip from HCMC to Dallas was operated by American Airline. Unfortunately they are 2 steps below JAL in overall quality. Regardless, AAStill got me where I needed to go on time.

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

My wife and I liked everything except the cold breakfast

The overall experience was ok, though there was certainly room for improvement. My husband was asked to check his carry-on bag at the gate due to claims that the flight was “full.” However, upon boarding, we observed ample overhead space and several empty rows of seats. This made the request appear unnecessary and caused some discomfort, particularly as he was the only passenger singled out for this procedure.

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

The flight was smooth, but there were not enough options for meals and I was given beef when I do not eat beef. The flight going was much better because we received more snacks.

Thankful for the staff who provided blankets cause the plane was quite cold and no way to adjust the airflow in the seats next to the bathroom.

Uh there was a delay, because of the weather. And what took usually an hour flight to Louisville took about 6+ hours. Flight got canceled

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Flight attendant took good care of my mom as she boarded on and off the aircraft from her wheelchair. I did not care much for the food nor the movie options Available. I appreciated the increased legroom available in economy. This was one of the main reasons we chose the airline. Overall, the good value and I would fly again.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

So far so good but food and entertainment are not available for this flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.

The crew were very nice. The Chocolate is good and v there’s no entertainment. Thanks

The crew were very nice. I would have appreciated a pillow for comfort. I had a special meal that was sloppy, but the salad was great. Thanks

The plane was in Moline all night. Consequently, we assumed an on time departure at 8:15am. Unfortunately, and as is the normal case with United in Moline, we departed 2.5 hours late. When the crew came, it was discovered that there was very little heat in the plane. Seems this should have been checked hours before the crew arrived. Then when we boarded and the plane was to be de-iced, the United de-icing truck was not working! We awaited the American Airlines truck. All of this caused us to miss our connection in Chicago. My suggestion is never take United Airlines flight from Moline. We have been disappointed 80% of the time and have vowed to not take United again from Moline.

Flight was delayed two hours. No snacks and no tv screens. My bag got stuck in Chicago
