We are on economy premium but they put us in economy seating? Asking why the fligh supports said : If you not happy you can claim for refund?

I liked everything but I flew business class and StarLux booked another passenger and a one year old , in business class The child cried 80 percent of the flight, the flight was a long 13 hour flight. I’m 75 and I have 10 grand children, I love kids But with that said it still made it not and enjoyable flight. Ask your great flight attendance what they think of the situation, they had to deal with. Let me know what they said Respectfully, Al Eaddy

Everything is smooth. Very good. Except flight arrived SFO 30min late.

more new movies and the blockbuster movies that everyone likes

Leg room was great. Friendly crew. Food is great. Crew always kept the toilet clean.

Excellent. Airline was very clean, staff was excellent, very professional. Economy seats were still large and comfortable. Meals were included and with good options. We were given a blanket and pillow as well as a comfort kit including an eye mask, ear plugs, and tooth brush. Would highly recommend.

Business Class is exceptional, from the lie flat seats to the wide range of food on board. Can’t wait for our next journey with Starlux!

Th tray was dirty when pulled it out. Still oily and food stains can clearly see last trip cleaner did not clean well. The toilet sink water did not drain quickly enough.

Majority of the movie entertainment loaded in the aircraft were quite old.

Crew is very attentive. Another new airbus 350-900 plane. Very modern.

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

Amazing customer service. BUT!! It would be nice if the flight attendants SMILE a little more, I know they are doing their job, but it is importantly to smile back and be warm to passengers. Nobody is trying to hit on them, it’s just being polite. So, please Taiwanese flight attendants: SMILE MORE WHEN YOU INTERACT WITH PAYING CUSTOMERS

It was easy going check in was easy and pretty fast entertainment was up to date on movies and food was ok

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.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

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

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

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.

Everything was fine except the seats were quite compressed and hard for the 12 hour flight

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.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

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.

Sat next to a woman who had her period. Blood was on her seat and on the arm rest between us. I ended up having period blood on my jacket and shoes. Very gross!

Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

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.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

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.
