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).

The plane is very clean. The selection of movies is excellent!

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

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

long flights are difficult but the crew and amenities made it a very good experience

Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

Excellent service, love the extra amenities (water bottles, blankets, etc.).

They had the same movie choice as my previous flight, not much of a choice, movies were not up to date, music was uninteresting. Other than sitting on the ground for 40 minutes after boarding the plane, with pilot telling us that they couldn't load the plane because of rain, (bullshit) We finally got into Bangkok of course 40 minutes late.

After the gauntlet of unnecessary security, and the two mile jog to make the flight, the flight was delayed 20 minutes on the ground for takeoff.. However, once in the air, the crew gave its usual excellent service.

They destroyed my Michael Kors Carryon luggage, they didn’t announce that only check in the carry on and when we get inside a couple of room to put the carry on bag. I was disappointed and sad because of the damaged of my luggage. They should replace it or fixed it.

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.

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

The internet on these planes stinks. Need to get starlink

Very bad multiple confusion and miscommunication which i ended up missing my flight.

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Update the cabin with tv screens or at least music sources.
