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.

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.

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.

The flight from SEA to Taipei was on a Boeing 787-10. Economy seats were unacceptably cramped and the seats themselves were old and lacking cushion. I'm only 5'3" and couldn't cross my legs as my knees were up against the seat in front of me! I could not get WiFi to work most of the time on both flights and crew were invisible except to serve meals. The onboard entertainment also did not work reliably and was very hard to hear through the provided earbuds. The Asian vegetarian meals were interesting. I hope they can provide a fully vegan option though these meals seemed to be already. I appreciate their providing these meals options for vegans. I don't think I'll fly a 787-10 if I can help it. It was the definition of a sardine can in Economy.

Amazing one of the best airlines i have ever traveled with. I live with medical issues called psoriatic arthritis and was in pain on the flight. The flight crew made sure I had fresh ice pack ever hour. Going above an beyond with service and care ⭐️⭐️⭐️⭐️⭐️.

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.

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

The hygiene of the bathrooms were terrible. Urine smells leaked out into the cabin and the seats were really tight, even for a petite woman like myself. Flight attendants did not go through the cabin enough to offer refreshments.

Pleasant, comfortable, and entertaining. All told, ZERO issues with it. And sadly, so far the flight was WAY more comfortable than the hellhole that is "Lambug Beach Resort" at Badian Beach!

We were not sat together for the longeset duration of our travel very uncomfortable didnt enjoy that they fed us at 2 am

Flight attendants. Food, entertainment and most of all, be on time.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

Better organization of boarding procedures. Terrible leadership guiding people to gates.

I did not like how the plane landed. It was not smooth.

China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

My BIG complaint was that my second flight was also delayed. That's very aggravating after traveling for 18 hours already.

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

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

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 amazing. I was not expecting the phenomenal customer service Asiana provides.

The boarding process was good. The toilet could be better maintained.

It’s wonderful service aboard. Delayed for departure but arrival in Korea went so well.

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.

Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

They could care less about you. Just under a 4 hour delay in Seattle, leading into a missed connection in Vancouver, which led to 2 more delays that added up to 3 more hours leaving us to have to sleep on the floor of the Toronto airport cause they don't help you find accomodations and they just book you on the next flight out. Took an additional 14 hours to get home. Always given the brush off to get rid of us. Worst airline ever

All was good with comfort and ease of boarding. There was confusion from what gate to board at. Meant moving a long distance but I allowed plenty of time for this.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

Air Canada at SeaTac was the best. Polite, helpful, all good!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Both fights were delayed. Food could be better comparing to other international flights

I found the personal kind and caring. The Problem was not enough people to serve the the customers. The flow was restricted the crowd frustrated by the wait times. Air Canada seems to hire good people but they need backup in order to provide the service we pay for.

The Montreal to Barcelona flight was cancelled half hour before boarding. We had to struggle for hours to find an alternative route through a very long route with 6 hours of transit time in Munich. It wasted almost one full day of our long awaited vacation. We are extremely disappointed.
