I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

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.

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

Amazing crew, excellent food, business class seats seem a bit dated but are super comfy even for a very tall person. If continuing onto Taipei, the stopover in Bangkok is a bit annoying (queue at security) though the lounge is decent.

Boarding is fast and easy for economy class, food was ok baggage policies are good

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

Delayed due to no fault of flight crew. Efficient and worked well together.

Paid for seat assignments that did not in any way match seats received, and had to upgrade at checkin

A little aged aircraft but overall good. Smooth fight and got us to Bangkok. Thanks.

All was great on flight to Tokyo. The ROOM setup was very comfortable. Definitely will try to do again.

Long haul from Chicago to Tokyo was great, traveled in the ROOM on ANA and experience was great all around. The flight from Tokyo to Bangkok was fine. Definitely a good way to go. Should have stopped in Tokyo for a bit.

I thought I purchased premium economy but got an economy seating for an expensive airfare from Kayak. Not able to pay extra to upgrade at all

On time, food was great. Didn’t wake me up when they saw me sleeping and as soon as I used the toilet, they came up and asked me if I wanted dinner. Right on!

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

One of the business class panels where we were sitting was broken and it didn’t close. Therefore, the be privacy was limited.

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak uses scammer sites to steal money from their victims.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was all perfect and very pleasant for such long flights

Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

Packed flight and not sure why dinner service would start at midnight while passengers we’re trying to sleep

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Good but not on par when compared with foreign flag carriers.

Good service but not on par when compared to foreign flag carriers.

Mechanical delay of 2 hours without telling us Canadians of the potential compensation for this delay. As this caused 2 out of three people in our travelling party to miss their connecting flights until the next day.

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Waited on tarmac for approximately 15-25 minutes before taking off. When landing, the time it took to taxi to our gate was the also 15-25 minutes.

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

Loved the easy process to board and the experience overall was smooth

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

I am United’s newest fan. The planes are clean, the staff is so friendly and snacks are more than just old pretzel crumbles. The captain came and said hello! Truly amazing experience

I absolutely loved it. ANA has got to be the best airline. At least the best I’ve experienced. The food was good, even in the economy class. The staff very friendly and helpful. The cleanliness was always on point even at the end of the flight. It also seemed like there was much more space than the previous United flight I was on

Staff members were not helpful they ignored all calls for an attendant.

Is ANA airlines not united airlines, ANA airlines crew working professionally , more services providing, happy face to service customer
