Hostesses were very nice I am disappointed that I paid extra 900$for premium economy which wasn't much upgraded from regular economy, I have wasted my money on this trip 😫

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

Flight cancelled due to inclement weather yet rival airline EVA Air with the same route departed 2 hours later and landed safely while our flight was cancelled and rescheduled for 36 hours later.

The crew could have been kinder and less pushy. The premium economy seats don't have enough cushion. The seats are to hard and the flight became painful and uncomfortable after an hour of flying.

Our transit in Taipei was disappointing. The ground crew could not tell us where the lounge was located, so we wasted 15 minutes trying to find it. The airline has a great review, but our experience says otherwise.

I thought all the while when I booked my flight I am entitled to check- in 2 luggages of 23 Kg each only to find out that the ticket I purchased online entitle me for only one luggage. I have been traveling for over 20 years and this is the first experience to such… so frustrating.

I was pleasantly happy with this airline, which is new to me. The crew was attentive and the seats felt better than most other economy. There was plenty of bin space. Glad I got to pick the seat I had(based on distance from baby image on seat map).

Great ! The services of crew members were excellent. The pilot did landing smoothly.

Premium Economy seats were more comfortable than other airlines I have recently been on. Great staff. Food was unremarkable.

The crew very accommodating and food too is good. Keep up the good work

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

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.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

Overall the flight was what might be expected for a long haul flight to Asia in economy class. The cabin crew was attentive and the food was good. Boarding was fairly fast and easy. The one thing I found frustrating was the EVA app. It is terrible. Trying to do anything on it was almost impossible.

EVA would not help with ticket issue since they were purchased through a travel agency. Even though it was EVA ticket stock. Travel agency Budget Air didn't reissue ticket after airline change which I didn’t learn until trying to checkin on Christmas Day and there was no contact number for the agency to help. I will never use Budget Air to purchase flight again and disappointed in EVA’s refusal to help. Thankfully just under 12 hrs before departure someone from the agency was available to reissue tickets. I was starting to think we would not be flying and the stress trying to resolve was completely unacceptable.

seamless check in/ friendly staff, food is good, always love flying Eva Air

Very uncomfortable and crowded seats in economy. Flight attendant refused request to move to nearby unused seat with more legroom because “It was more money for that seat”. It was also near impossible to reach airline directly by phone. Waits upwards of an hour and not very helpful customer service representatives after long wait. Cannot recommend this airline.

We were not sat together for the longeset duration of our travel very uncomfortable didnt enjoy that they fed us at 2 am

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

Better organization of boarding procedures. Terrible leadership guiding people to gates.

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.

Unable to set seat assignment. Got a call from presumably “China airlines representative” but was asking for an exorbitant amount for the seat assignment. Was traveling as a family end up being assigned to different seats as a result. Will never use underpricer again.

Not many selections for entertainment. Bulk head seats are no longer available with out fee at the counter. That’s pretty lame.

I would have liked to know how to order a special meal (for medical purposes) before the flight.

Ask flight attendant for water during flight and she was a little rude get the water.

For a long-haul flight, the crew did a very good job of keeping the lavatories clean and the aisles clear.

The check-in crew at SF did not put on breakable glass stickers on check-in baggages which caused my antique whisky bottle to break during transportation.

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.

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.

Love flying Asiana. Been using it for over a decade now.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

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

I like the food, the crew and everything.!!! Except for the delay in our flight.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.

The flight was delayed for 2 hours, however, we flew home safely.

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.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Bathroom was not cleaned as often as other airlines does. It was gross for a less than full flight capacity.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight
