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

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

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 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.

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

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

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

They could have had more up to date movies/better choice of music.

Terrible experience will never fly Delta again. Delayed flight with total disorganization and inept crew who wouldn’t communicate.

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.

Great service. Was there a food option? I was given food (I could have ordered ahead of time?) but had no choice. I like choice.

delayed and the cabin crew was like trainees.. a bit careless and not so pleasing to their job

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 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.

Plane is new and I was upgraded to first class so all was great.

The flight from Taipei to LAX was the first time we encountered rudeness from the crew. From the gate agents to the in flight crew. We had received such wonderful service going to Bali and on our Bali to Taipei flight that it shocked us when the gate agent was rude and then the rudeness continued on the flight to LAX.

Overall great experience. All four members of my family were seated together without paying extra to reserve seats. Everything was on time. Food was great and healthy. Media entertainment was good. Rock music could be added as a listening choice. No issue with baggages. Flight attendants were friendly and helpful. I would recommend EVA to friends and family.

As a senior traveller it’s difficult to be seated all the way at the back

I was expecting that movie selection and food would have been better. Everything else was great.

Great experience for a long 13-14 hours flight. Great pilot and crew, everyone is pleasant and attentive to the passengers.

Seats in "Premium Economy" were noticeably more comfortable than those in "Economy" and worth the price. My only reservation is that the foot rest did not go higher up. If it did, it would have made the seat much more comfortable.

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.

I purchased the ticket online and went to do online check in amd the app wouldnt let me. I went to the airline desk and they couldnt confirm my ticket in their system. I ended up having to buy a ticket from the airline directly and paying twice for the same flight. The app wouldnt lwt me check in the kayak purchased ticket until after my flight was taken off.

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.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

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

The staffs are very accomodating!!! The foods are good!!! The entertainment from manila to incheon was miserable because we need to use our own cellphones or own ipads.

Typical Asian airline - flight attendants like robots - start food orders at first row and get to the last row right aisle last - no food selections left. 30 minutes before landing demanding everyone put seats back into upright position, window shades open and God forbid you might have to use the restroom a full 30 minutes left into a 1 hour 45 minute flight. At least the flight was cheap - but that’s the best I can say about it.

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.

Very comfortable seats, delicious meals, and friendly and helpful staff

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

Everything is good, the only issue is the aircraft need to be upgraded

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.

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! 🤛🏽💗
