Airline reviews

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.

Overall was good but it would be good if the airline is providing snack such as sandwich or instant noodle between meals for LA to Taipei

We really enjoyed our flight to Seattle. The food was great and service was attentive.

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.

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

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 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.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

Overall was a lovely experience. The crew were kind and courteous throughout the entire flight.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

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

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Later on, when there was no more bottled water, the water we received had a strong chlorine/disinfectant odor. On my flight from Hong Kong to Los Angeles, there was a male flight attendant who had a mean attitude throughout the whole trip, and he was very impatient during meal service “Furthermore, we purchased a Hong Kong SIM card as part of our flight package, but we received no instructions—neither by email nor SMS—on how to activate or use it. Consequently, we were unable to use the service at all. We request a full refund, as this appears to be a deceptive charge

Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

No screens or meal options. Freezing cold. Dirty seats. Left late.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.

Some crew were unfriendly or in some cases just straight up rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

Due to cancellation of connecting flight (Lufthansa) I didn’t fly with United

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

Departed Palm Springs over an hour late because there’s only one gate, and it has always delayed by the arriving and departing flight to Toronto and the arriving flight from Vancouver.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

The flight from SFO to YVR was delayed and my bag did not make it to my next flight from YVR to SYD. It took almost 3 days after I landed to get my bag and when I got it, it was filled with dust

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

They rescheduled me and I had no issues with the new flight
