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

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.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

The 1st class male crew member was very pleasant - the short female with round glasses , maybe in 50’s had no personality- never spoke when delivering my food, drink, & never smiled the whole trip! In fact looked annoyed when the boarding proses was happening- I would never hire this woman - unfriendly . Have never dealt with a crew member like her-

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

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.

Very friendly und helpful crew. Looking forward for some more flights in

My husband and I had to split seats and I did not like to seat at the window.

The flight was very smooth and comfortable. The entire flight crew was very professional and provided excellent service. Thank you.

Very smooth flight, great landing- entertainment didn’t work so well

Pilot and first officer did really an amazing job. I can best discribe their flying as finesse. Inital service with food/beverages was great, however after that the crew just kind of packed it in and were sitting in the galleys chatting for the remainder of the flight. I wanted a bottle of water, went to the mid plane galley, was told they were only available in the back, so had to walk the length of the plane just to get a bottle of water. That was a new experience on an airplane for me. Pretty sure evem Spirit will bring you the bottle of water you are paying for. Seat was comfy, magazine worth the read. Entertainment nonexistant unless you want to pop for the $4 headphones.

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a flight operated by Lufthansa. See me prior comments, which were meant for this experience. The CSA, Ashley, should be reprimanded if not fired for incompetence, being rude, and very, very slow. She was whispering to other CSAs, blaming my flight change on others, unable to give me a seat assignment, telling me could not help without offering any advice (I travel 200,000 miles a year and am a consultant to the airlines, so I know how this gets done PRETTY DAMN WELL). Then, she gave me literally the worst seat on the airline (yes, there were other seats open) - the one right next to the bathroom that was so bad the other PAX next to me left to move to another seat. My seat kept getting rammed (3x) by the crew with their carts (no turbulence to speak of), other passengers grabbing the seat to get in or out of the bathroom, and listening to the bathroom flush all night.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

Food wasn’t very good, old business seating configuration on an old A340

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

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.

They canceled the flight on us very close to the flight date .

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.
