Overall, very uneventful and pleasant experience. Most importantly, no delays.

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

On time and flight crew are always so happy to help and always smiling unlike other airlines.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

You did not put me on a Korean Air flight! so I do not have nothing to say

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Short flight but delayed. Since its a short flight no food or entertainment necessary

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

Having movies helps past time I wish going Vegas had something

First flight got cancelled. Got booked for another flight departing 3.5 hours later which ended up being 1hr delayed... The flight was good when we finally ended up flying.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

The flight was delayed almost 2 hours. Bad customer service etc. I will never fly Luthansa. Ever!!!

On time take off…US cabins look tired and need of refresh!

Fine. Though no food or entertainment so the survey needs to be updated with those options.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

The flight was excellent the problem was that my luggage was damaged (zipper pulls ripped out) and it is difficult to contact the number to claim the damage while in another country and going back to the airport is not an option and no matter what I tried I got the same response to just call the number that is not possible for me to call in the first place. So very disappointed that I can’t claim such damage and that now I have to take part of my trip looking for a new luggage.

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent

Delayed leaving. On arrival we were taken to the airstrip and had to get off onto an over crowed bus, not all that passengers fit. Drove around the airport for 20 + minutes. Taken off the bus told to go upstairs 3 flights then all the passengers had to walk a mile or more , those of us old there was no one to direct us to were to go. I asked several people with no answers. Once I got to baggage claim my bags were not on the right bag claim. Once again asked for help and finally someone found my bags on a different carasel. Very frustrating.

Excellent host on board. Not so friendly check-in staff. Older plane with no food or entertainment due to short flight. Friendly captain and crew.

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.
