Thanks for fixing the title of this question... the flight was a DELTA one marketed as a Korean Air flight. Which automatically makes it worse. The crew were actually rude in several cases and clearly lacked cultural sensitivity to the majority of the passengers (Koreans). This flight was also a minor heart attack before it started. Firstly, I thought I was buying a flight from Kayak, but it turns out they just acted as a front for this other company, UnderPricer, which took almost 24 hours to send a proper confirmation of the flight. We could not select the seats at checkout time either. We later submitted our seat selection to Korean Air, who proceeded to mess up the instructions to Delta, so our family was separated on the flight and our aisle seat was replaced with another middle seat.

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.

It was a comfortable flight and the flight crew were lovely!

I won't hesitate to fly with Korean Air again and agian....if I can get a good deal.

Glad you had Bibimbap which tasted much better than mesh potato or pasta.

The flight attendants seemed to be a little more grumpy this time. A350s could use more toilet stalls.

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

Absolutely horrible. The fight member crew or not very friendly and the food was horrible.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

The team members are extremely attentive to make sure you have the best experience.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

The plane was dirty, there was trash in the seat pocket in front of me.

Food was excellent, the crew was exceptionally friendly, and the seats were comfortable. Bathroom were also kept very clean and odor free.

They woke us up 2.5 hours before the flight was over? Why? If I'm on a long haul flight I want to sleep as much as possible. Also, didn't mention the mattress pads in business class so missed out on using those. The western meal of truffle, salmon pasta was the awful. Had a different fish dish on JAL that was great but that pasta was a mish-mash of too many random things that didn't make sense plus dry fish. Staff was friendly and helpful.

I loved Ryuichi Sakamoto's OPUS in the movie choice.

Overall, it was ok. However, the food was very sub-par.

It was okay overall but the food was very, very bad.

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

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

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

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.

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

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

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

Customer service was exceptional. I heard it wasn’t a great airline, my opinion has changed after flying with them

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

EVen warmer in the plane it think it was 24+ degrees

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

I never made this flight but the staff helped to get me rebooked (see previous review)

No land services during boarding, specially while moving from terminal to another

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.

The plane itself is old and way overcrowded. The crew do a great job of trying to mitigate. It is just uncomfortable for over 8 hours, bearable, but barely. Boarding, and the baggage game, is ludicrous. Why charge extra to check bags when there is not enough room for everyone to "carry-on" and checking is needed? I do not think these issues would be different with other airlines, I believe it is the attitude that squeezes every penny out of each traveler.

Expected a lot better service paying for a business class seat. Seemed to be short on staff and did not get the service I expected.

I flew Club World and was SHOCKED at how totally absent the crew were for the duration of the flight. So much so that we received no drink service other than the post-departure cocktail and that was it. Wasn't even offered tea/coffee and the in-flight attention was so bad that literally minutes before landing the one crew member for our row was scrambling to pick up left-behind water bottles, glassware, trash. And the rest of the crew had already stowed all carts, he was cramming the trash into the lavatory trash can and was stashing the glassware frantically in the galley as we were on final approach. He was so scrambled he left two overhead lockers wide open (that he'd opened) for landing. Unbelievable!

The flight was several times changed. That was inconvenient, to sah the least.

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies
