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 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.

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!

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

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

A little more room from the reclining seat in the front of me.

They ran out of the second choice of food was stuck with fish

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

toilets could be cleaned more frequently, everything else was pretty good.

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

I thought I already provided this feedback. 12 hours with no wifi is unacceptable. Lay flat is nice but a bit cramped.

The vietnam airlines app was not able to allow checkin with the confirmation nor with the ticket number. This led to quite a bit of consternation. Speaking with a colleague from Hanoi, he did tell me that their app is not the best. It may be best to inform travelers to only use the link and to plan on checking in at the airport for this airline. The check-in was very easy and the staff were excellent.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

This was our fourth domestic flight with Vietnam Airlines, and once again we found the experience very suitable. Check-in was easy and efficient. They did take our carry-on luggage, but that was fine. I’m actually happy not to deal with it on such a short flight. The flight was just over an hour, departed on time, and we climbed above the clouds into a beautiful sunset. Even on such a short flight, they served water, which we appreciated. Luggage came out into carousel in Nha Trang in good time and off we went to meet our GRAB. Also, Vietnam Airlines have easy to locate ground level offices in cities and towns where you can get assistance with staff. I liked this service as we did go visit one in Nha Trang. We would definitely recommend Vietnam Airlines and wouldn’t hesitate to fly with them again.

Really good 👍 This was our first time flying with Vietnam Airlines. It was a short domestic flight, so no meal service, but boarding was organized and the flight departed and arrived on schedule. The flight attendants were professional and neatly presented. All in all, a very good first experience. We would recommend Vietnam Airlines.

We flew with their partner VESCO on a small plane, it was a really good flight. There was no food or entertainment as it’s a one hour hopper flight.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

This is a very short commuter flight, so there is no food or flight entertainment. Hence, I marked it in the neutral flight left on time. The plane was full pretty much and it was a pretty easy flight overall very good.

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.

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

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
