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.

I am really satisfied with Eva Air and will definitely fly with them again.

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.

My luggage was lost and didnt arrive in manila yesterday. And until now im still waiting for the confirmation if my luggage is teady for pick up in terminal 1

I always preferred EVA air every time I visit Philippines. It’s just this time that I have to be very early to make sure that I don’t miss my flight due to TSA problem. There’s only one choice of food serve which you use to have 2 on our flight from Taiwan to Philippines . Otherwise I will still use EVA air in my future flight.

Service was great. Flight schedule was on time. Staffs are friendly.

We boarded late and it snowballed from there. Had to wait behind 6 other flights to take off before us. Then, arriving late to our destination, we had to circle in the air for 20 minutes. If that's not enough, the seats are very cramped on their iteration if the A321neo. I'm 6"3' tall and my knees were pressed against the seat in front of me. These are not the slimline seats that offer less cushion with more leg room. I had no room to move my legs. Since I am an adult male, I also had no shoulder room. I sat on an aisle seat to have some space to lean my should out. But the walkway seemed to be more narrow than I am used to see. I felt bad for the middle passenger because there was just no where for me to put my shoulders except into the middle seat person. I don't plan to fly in this airline again in this configuration. Pack everyone in and lose my business.

The crew are amazing. Very professional, polite, kind, and accommodating.

The crew was very professional and friendly. Although there was a water leak from panel above, the crew was trying to mitigate the consequence. We are happy with its service and the value offered. We will definitely take China Airlines again.

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

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

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.

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

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

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

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.

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.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

Better screens, it would have been nice to have more comfortable seats.

I upgraded my flight to business and before boarding they told me they will not have food on the flight unless someone declines the food service.

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.

Nice staff, only one of the food services had a vegetarian option. Premium Economy was good - big seats and footrest. A little slow bringing welcome drink and often didn’t have the prosecco left on the tray - as though they are discouraging choosing that option. My only complaint is the wine/drinks served in a paper cup - I ordered a cognac on our previous flight and it came in the bottom of a paper cup, wine is poured into the cup like it’s a bucket!

Flight was delayed due to air traffic control and technical issues - power outage happened several time during taxiing in Taipei causing further delay for urgent technical check.

Cathay has always been great. Even allowed some leniency on my baggage weight. I believe they are also on the more leg room side of airlines.

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

If there is any negative rating for kayak and also for Cathay Pacific or the dealer I used I would give all of them -1000000000000000 I will never ever use kayak again you scammers you rip me off with everything

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

Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

Very attentive crews Flight was very smooth and safe Only little disappointment was the slight delay of departure (~30 minutes ) which rarely happen with CX flights

Flight was overbooked and seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

It was pretty straight forward, no glitches or hidden costs

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Didn’t make it on the flight. Delayed then had to be rebooked, which in turn had me waiting at the airport for another 8 hours before next flight

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

Selected seats 5 months prior to date. Had email confirmation and seats were not honoured. Family did not sit together

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

The flight was comfortable and the staff were helpful and friendly. However, we did not know we were flying PAL until we arrived in Canada, so it was a bit disconcerting. In addition, which port we were leaving from was confusing.

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.
