I put the review all together for the first review

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.

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.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

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

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

UA discouraged people to choose seat on economy class by charging about three times of another airlines. For example, ANA will charge USD60 to choose an aisle seat but UA is charging USD 219.

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

I usually like delta. However this is my second flight that the wifi does not work

Leslie the gate agent was incredibly helpful with helping me get on an earlier flight! I saved several hours of airport time thanks to her, and she made the process easy and quick.

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

The trip to Harrisburg from Detroit was extremely uncomfortable because of heat

Flights were on time, my connecting gate was VERY close to my arrival gate, everything went smooth and made for a delightful experience.

The flight was freezing cold. I had on pants and a sweatshirt, had to wrap up in the blanket provided AND put on my rain coat, and was still chilly. Have never been on such a cold plane.

The flight was delayed to board, then delay in landing and extremely bumpy landing.

Late flight, screens not working and still had to pay for a drink

great! appreciated the last minute upgrade to Comfort+ exit row, as well

Crew completed ignored our aisle when giving snacks and coffee

Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.

On time. Carry on and personal bag was accommodated on the plane. Entertainment was accessible without bringing own device. Whole can of juice was provided rather than a pour.

On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.

Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.

overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

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
