Aircraft was late getting to the gate - probably due to weather. We left the gate one hour late and had to wait another hour since we lost our slot in the takeoff queue. Our box was very wet and was falling apart when we got to Clark. It appears that luggage was exposed to weather in TPE while waiting to be loaded. Crew, however, handled the delay well and was able to provide planned service.

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.

For the price, it was better than other airlines; quality of food and service was very good.

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.

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

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.

The food is quite mediocre. I had spaghetti and the tomato based sauce was quite salty and there were no other flavors, no spices used in the sauce.

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

The boarding process for Korean airlines is very straightforward and easy. You've never met such helpful and friendly people. The food was great and the entertainment options were excellent too. My teenage boys found programs they wanted to watch while I had fun watching a full season of the Last Man - the Blind Investigator (Japanese), which my wife enjoyed too. My only complaint was that it takes a very long time to taxi at ICN (20 minutes) and the pilot had to hold at the gate for 10 minutes after our scheduled departure time, which meant we got to Seattle 27 minutes late. Luckily I had a long enough connection to make my next flight, but just barely.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

My second flight wasn't better than the first one. And this is 14 hours trip, crew came out only to offer food and the choices was poor. This food choices are good for Asian people but not for westerners. The breakfast kind thing was a corn sausage really disgusting. The air-conditioned blower really blow high and cold, turn out on my arrival to feel seek, that makes the trip uncomfortable. The crew didn't not really come out during the trip to offer drinks or snacks. No fruits available. Very poor service

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

Need to have space for Cary on when traveler boarding any zone

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!

My ticket did not indication which group I was in for boarding; the gate attended help me

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.

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

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. Two meals were served on this flight; one was a repeat of the meal I had had on the flight immediately preceding this one, which was bad enough I didn't even try it. Drinks were very limited. All I wanted was water, and on a 10.5 hour flight, I was given 3 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.

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.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

Worst experience I have ever had with any airline in over 25 years.

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

The flight was delayed for 30 mins. The overall experience was good.

When comes to Taiwan airlines China airlines is the best rest are pure trash

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.
