Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

The flight attendants should be nicer, on my first flight I told them I’d prefer a veggie meal sometimes and then she began to lecture me about it, it was a late flight and I wanted an easy digestion meal so that I can sleep quickly. The meals were abit odd, breakfast on my last flight had eggs, oatmeal and fish, did not taste good at all, strange combination. The economy seats are very tight and crowded, not comfortable at all. Overall for the price I paid I thought I was going to get more.

Clean plane, friendly crew, mostly on-time departure. Negativo since there were no snacks offered. Cold drinks only was fine due to turbulence, but nothing to eat? Really?

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

Poor food on board, but seats are too small and uncomfortable

1. The entrance to boarding gate G5 (which is at a lower level) is from the walkway (which is at the upper level). That entrance was locked and there was no place for hundreds of people to sit at the upper level, for a long time as the flight was 45 minutes late. 2. The choice of movies on board was extermely limited and poor. 3. The staff was unhelpful and faked politeness.

They didn’t have ice for the drinks and only gave you half a cup of your beverage. Did not have enough water. I got dehydrated

Fast boarding process. Flight was expected for a long haul economy flight

The flight went well. Everything good. Boarding. Meal service. Snack (crackers) & Drinks. Entertainment was good as I watch 4 movies. The need to have milk for hot black tea though as coffee creamer just never makes tea taste nice.

Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Very nice staff and very good choices for food and drinks.

Crew was fantastic. Seats were not completely lay flat but still comfortable to watch a show. International food was lobster which was very big but a little tough. The scallop appetizer was delicious. Loved the individual air conditioning vent at each seat. Flight overall was very smooth and very good.

Overall good except the checkin process at Bangkok airport. Can ANA explain why the line for business class is longer than that for economy? I, BC passenger, had to move from BC line to economy line to get faster service.

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I always take ANA because of the great service and overall experience.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

Ticket was purchased as a United Airlines flight (operated by All Nippon) like what does that even mean? Makes for a VERY confusing flight experience. For instance, what do I look for a United drop off signage and ticket counter or ANA? No explanation anywhere to be found. I also felt a little bit scammed by the obsurdely restrictive seat selection provided. Only middle seats available!! Are you kidding me!! On 6hr + 10hr flights you're forcing me into the middle seat without telling me before I purchased the ticket?? This should be illegal. And to top it off, on the Tokyo LA leg there were quite a few empty seats including window seats! I must also say, the food was a dissappointing as well for my taste, fish with rice ( mostly plain white rice) or a vegetable medly for the breakfast meal? Should be at least 4 choices and at least 1 with eggs. Outside of these issues flight was otherwise ok.

This is a very long flight and the first time I have flown on a Japanese airline. I was very impressed with the staff. They worked hard and offered food and drink regularly. Plane was very well cared for. The let room was good . Food was ok but better than other airlines.

I love everything about this airline but it could be better if the waiting time for boarding is on time.

Great airline and staff. Thanks for comfortable, safe trip home. My best wishes to all United staff. Stay safe.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

Coming back to America was a peaceful flight everyone and everything was perfect

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

Staff always with a smile and very helpful with my mom who has mobility issues.

The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 cups of about 3 ounces each.

We took business class, It was comfortable and I was able to sleep.

Great service. They could offer vegetarian food and do more to reduce waste.

Very comfortable seats, delicious meals, and friendly and helpful staff

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

My flight from Atlanta to Oklahoma City was delayed multiple times. I ended up arriving in Oklahoma City nearly two hours later at around 1:50 am the following morning. This was a highly disappointing experience.

My Delta flight 2423 from Atlanta to Oklahoma City got delayed multiple times. It was originally scheduled to depart at 10:41 pm EST with a 11:58 pm CST arrival in Oklahoma City. However, after multiple delays, the flight finally departed Atlanta at around 12:40 am and arrived in Oklahoma City at around 1:50 am. What was even more disappointing was that none of the crew members acknowledged, let alone apologize, for the delays. These delays were not due to weather and were only due to operational/mechanical issues on the part of Delta. As a former Platinum SkyMiles member, I valued loyalty with Delta. However, after having similar experiences in the recent past, I'll be switching my loyalty over to American Airlines going forward. This was a highly disappointing experience.

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

Amazing, delta One is extraordinary. Worth the money. They took our bags at the door when our driver dropped Us off at Heathrow.. the Virgin CLUBHOUSE lounge was wonderful and the flight was great. Service food our little pod all near perfect.

This flight was the flight we missed due to deltas delay at our first airport going TO Atlanta.

In-flight: great! Efficient & comfortable, no complaints. On the ground: quite the opposite. The flight was delayed with no real explanation. If you can fly direct with Delta that's your best bet. Connecting flights with them when one is delayed, especially if the next flight is to a small airport, really was a mess. They did correct the problem with no cost to us, but it made getting home a 24 hr journey instead of 8. Also, staff at the gate at Minneapolis was NOT kind at all.

The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.

It was good flight was smooth, little cold on the plane but other wise good.

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

I had bad experience with United airline. No live rep, they only have AI that respond to customers concern

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

Flight and crew were great. Need more legroom and do not allow seats to recline.

Bathrooms broken, Wifi not working, Direct TV stuck in a United credit card loop for whole flight

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Definately tried to book business class, didn't realize until way later I didn't get it.

Absolutely terrible. I booked my ticket with ANA and underpricer/kayak asked me to change all my return flights to United. Customer service does not exist with United. Flight attendants are rude, self-centered, and unhelpful. The food is served cold and uncovered. The in-flight video controllers do not work properly. Premier economy tickets with ANA, allow you access to all airport lounges, while United does not allow access to any lounge. Mockery of an airline.

A great experience with excellent service by the crew and attention in assisting the passengers.
