They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

Great food on both legs and fast customer service from the stewardesses....

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

The crew need to be more friendly it seem everything such a rush situation during dinner and breakfast. Smiles to the passenger go such a long way just the service from Seattle to Taipei, service from Taipei to Bangkok were great more pleasant the flight attendant from Thailand she was very nice, as far as entertainment were amazing , wiffi connection was incredible great, I will be able to charged my phone from Seattle to Taipei and from taipei to Bangkok I won’t be able to do so flight attendant told me that because I don’t have the original iPhone charger connection has nothing to do what type of charger I have so she said there is nothing she can do about it. Foods : from Seattle to Taipei were ok no flavor , from Taipei to Bangkok I have chicken teriyaki the rice is overcooked all the flavor stuck on the aluminum wraps , breakfast the congee was on point and delicious. Will I recommend anyone to fly with Eva air go for it so you can experience yourself for myself I won’t fly with them again I’m gonna stick with Singapore airlines instead.

Never went. Got rescheduled with Phillipine Airlines to Bali, which was fine.

Staff show very stress with delayed flight more than passenger.

Seats could have been more comfortable, but it was a pretty good experience all things considered

Poor services. Not meet 5-star airline standard. Disappointed with the poor food and drink selections. Cabin crew is not attentive at all. They even skipped me during meal service (not sure if it is intentionally).

All went well with my flight I would recommend this to anyone who asked how my flight was

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

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.

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

The carry on baggage was collected before boarding without further information where the passengers can collect them . When the flight arrived at Tan son Nhat airport, it was very complicate to find the luggage

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

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.

They are very helpful and friendly. The entertainment is great with many choices. They will refill your drink and there is plenty of meal service. I’ll fly with them again when I transit Tokyo.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Seats had more space than expected. No recline, that is good.

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Boarding was quick and efficient. The food was very good and they had pictures showing you what options there were to avoid misunderstandings.

Boarding was fast and efficient. Not a cramped plane and good comfort. Food was great and attendants were very nice.

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

The flight was canceled due to a mechanical problem. The rebooked flights were snot good. Many complexities. Will not use a third party booking again.

Our flight that was before this one was delayed, and I appreciate that this airline sent a very nice flight attendant to pick us up at the Chicago airport and walked us to the gate. They waited for us, so we didn't miss the flight. That was amazing and outstanding customer service! We appreciate you so much!!

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Really good food and service. Qatar Airways is again and again provided an exceptional experience.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

The hindu meal food did not taste good. Also the seats were not comfortable as compare to other airlines

The first and longest leg, Washington to Doha, was in a 777 that was very loud. This was an older aircraft. The second leg, Doha to Delhi, was in a much newer aircraft, an A350 and was very substantially quieter. The service was good on both, though as always, the crew leaves you trapped with your meal tray for a really long time. Additionally, the flight crew seemed inordinately afraid of turbulence, keeping the seat belt sign on for long stretches when there was barely noticeable turbulence.
