Seats are not table comfortable. Crew members are pretty good. Can be much better!!

Very pleasant overall, although the movie selection could have been better.
Very pleasant experience overall, while the main course of the meal could have been better and the movies could have been more recent and with more variety.
I usually have ear problems when planes land. But the landing was so smooth I didn’t even notice it landing! The service was excellent!
the aircraft was fine and new. The crews can have better training. Their operations are not as smooth as EVA's. They are VERY stingy with drinking water. Throughout the entire flight, no one offered me any water and snacks. I still prefer EVA after trying out Starlux initially with lots of excitement and expectations.
Everything was smooth and professional. They could improve the raw vegan meal with fresher offerings, but otherwise they are now my favorite way to fly to Asia.
Leg space is small. Need more room for long flight.

Amazing!!! It really is good! The seats do go back far to relax so if you don’t like the person to go back, just adjust and go back and everyone goes back to settle and be comfy. Enjoy few free drinks and the little amenities they provide.
This Airline is really good! Better than Eva air for sure and more luxury. I really liked all the small details and amenities plus it really is free alcohol!
Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea
seats are pitched well. you don't feel too tight.
I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.
I was sleep when they brought the food. They had put a note on my seat. There was no food when I asked for food later. There was just one main meal served in this 14 hours flight. They offered me sandwich with ham which I don’t eat since I am pescatarian. Long story short I had to wait to get to TPE to get something to eat. I am extremely disappointed from the service. I have been flying EVA since I was 1 year old. Perhaps no more EVA for me. Seems EVA glorious day is long gone
Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.
Good. Please add a non- applicable category to your questions.
The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.
Boarding was good. It will be nice to have beer anytime. I asked for a beer at tea time & I was refused. Quite disappointed
Good experience but could be better for people with injuries and needing extra assistance
It was a good flight. I would highly recommend it to family and friends.
Staff was so nice and very helpful with directions aswell!
Most relaxing long distance flight I have been on. And I have flown on many.
Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…
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!
Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer
I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!
staff are super nice and effiecient! It was a very comfortable and relaxing flight
When I booked a premium economy ticket. I then had to pay $100+ to book my seat.
Didn't like on this return inbound flights (from Hong Kong to Vancouver) Outbound to the Hong Kong was good.
I did not take the flight, tried to cancel it right after I booked it, but was unable to reach anyone. I blame Kayak for this situation because they sent the booking through another company and I was unable to get anyone to talk to me about the situation. I had to just take the hit and pay for another flight through Cathay Pacific, which was wonderful. I will never use Kayak again. (I bet they don’t post this review!) I’ll just post about them on social media sites. I don’t want anyone to have to go through the hassle and expense I dealt with.
It was amazing. I was not expecting the phenomenal customer service Asiana provides.
It was all perfect and very pleasant for such long flights
The seats felt very small. We were supplied with pillows and blankets, which was nice. Lots of noise from the bathroom, plus exterior noise. Made it hard to hear the entertainment system, even using my own noise-cancelling headphones. The food was really bad. I generally request a vegetarian meal and one was supplied, but the pasta was cold and hard and there was nothing pleasant about it. Drinks were very limited. All I wanted was water, and on a 4 hour flight, I was given 2 cups of about 3 ounces each.
We took business class, It was comfortable and I was able to sleep.
Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.
For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.
Only process that my luggage didn’t make it to my destination because of short connection but I understand
The boarding process was good. The toilet could be better maintained.
This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.
Great service. They could offer vegetarian food and do more to reduce waste.
The food and service was great. You have to pay a lot for in flight Internet though which is lame.
I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!
So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.
Very noisy and careless crew on this overnight flight. They should understand customers want to sleep
Everything was fine and I have no complaints or things to note.
The economy seats are much indeed roomier. Meals needs improvement.
It was okay overall but the food was very, very bad.
flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -
Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...
Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.
