The crew very accommodating and food too is good. Keep up the good work

The crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

Staff show very stress with delayed flight more than passenger.

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

Great experience, comfort and food is delicious. Always great service and one time

Excellent service from check in to boarding the crew is so pleasant to asked

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

Everything is good staff is polite and helpful flights are on time sub sandwhich for a snack was good with a bottle of water only thing maybe more variety of food like breakfast or dinner depends on the time

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

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.

Lucky the weather was perfect as it can be not a great flight if it is stormy

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.

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.

Luckily I just tried to sleep. But the entertainment system was awkward to operate. I hate all this stuff with apps and adding it to your phone and all. It is a nuisance. I would prefer a good magazine or newspaper in the pocket in front of me or available.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

Leg room wasn't that great. Other than that it was a good flight

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

If my return flight was not so much better, I would have given an excellent review.

Chicken pieces were too big with pasta. Need to be smaller.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Cabin crew is very helpful and nice, it is another level of service compared to Air Canada

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

The flight attendants were rude. Seemed like they didn’t want to be there. Except for one girl that was really nice. Seats are sooooo uncomfortable. They give you a piece of paper and a thin cushion for a pillow and blanket that does nothing. Airlines have gone way downhill, especially United international flights. Food was disguting. Definitely flying ANA next time.

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

It would have been better if the crew has supported my husband's reasons for needing to keep the space clear around his feet, rather than insisting that he put his knapsack in that space.

Subject: Formal Complaint: Discriminatory and Unprofessional Conduct – Request for Immediate Action & Compensation Dear [Airline Customer Relations Team], I am writing to file a formal complaint regarding my recent travel experience with [Airline], which was by far the worst I have ever encountered. What occurred was not only unprofessional, but in several instances discriminatory, unsafe, and unacceptable. On the first leg of my trip, I arrived only four minutes past check-in. Instead of making any attempt to resolve the matter, your representative flatly denied me boarding and made me wait while she attended to passengers who arrived after me. By the time a manager intervened, it was too late to board, costing me time, money, and unnecessary frustration. The second leg of my trip (Chicago–San Francisco) raised even more serious concerns. From the outset, it was apparent that the staff—particularly two attendants—prioritized Caucasian passengers while dismissing African American and minority passengers. • When a Caucasian passenger in the exit row refused to comply with federal safety requirements, I, as a first responder, immediately offered to switch seats and assume the responsibility. My offer was blatantly ignored, and instead, a Caucasian passenger seated further up was chosen. This was discriminatory and deeply insulting, especially as I was actively de-escalating the situation that could have delayed the flight further. • During a lengthy tarmac delay of over 90 minutes, passengers were given conflicting and unreasonable instructions that created unnecessary distress and tension. • Throughout the flight, a visibly intoxicated passenger directly in front of me was disruptive, rude to others, failed to comply with seatbelt and electronic device rules, and yet faced no enforcement from the crew. In stark contrast, I was singled out for repeated compliance checks even though I was following every rule. This unequal treatment was so obvious that multiple passengers around me spoke up in my defense. This pattern of behavior demonstrated a clear lack of professionalism, disregard for passenger safety, and discriminatory treatment. I expect far better from an airline of your stature. As a paying customer subjected to this unacceptable treatment, I am formally requesting: 1. A full investigation into the conduct of the staff on both flights. 2. A written apology acknowledging the discriminatory and unprofessional behavior I endured. 3. Appropriate compensation for the distress, inconvenience, and mishandling of my travel. If this matter is not addressed promptly and thoroughly, I will have no choice but to escalate my complaint further, including filing with the U.S. Department of Transportation and sharing my experience through other channels. I trust [Airline] will take this complaint seriously and provide a timely resolution.

Check in was quick and easy during early hours. Flight was on time, and customer services was a plus.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.
