My flight with Korean Air went quite well, I've flown with them for many years and have grown accustomed to their great service.

My flight with Korean Air went quite well, I've flown with them for many years and have grown accustomed to their great service.

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.

The flight who provided services on my row had some not-nice attitude and not smiling at all.

Very good , the weather was terrible, but i admired the professionality and politeness and care from the crew, and the excellent contition of the plane

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

The plane was uncomfortable. I paid extra for more legroom but the seat was still uncomfortable. Other seats on the same exact row didn’t have to pay extra but still have extra legroom. I didn’t understand why I needed to pay $170 for. It was Iike China airline just wants to make money off their passengers. It was unfair.

They were helpful, considerate with asking us for standby preboarding with our infant, gave us toys and excellent service onboard. They were always on time, even early boarding once! All our luggage arrived intact, and they even brought our baby car seat to oversized for us. We love China Airlines!

Staff is friendly, great variety of entertainment, check in a little messy but due to people not listening. Overall a pleasant experience. Would use again in the future.

3 of the 4 flights had delays despite the weather being fine, but still managed to make all connections

Ask flight attendant for water during flight and she was a little rude get the water.

Baggage made it successfully to destination despite short layover. Appreciate that.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Not worth the premium paid for the first class ticket

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

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

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.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

My flight got canceled. Then AC rebooked me to a next day flight. No compensation no apology. It almost messed up my entire trip and schedule. However, all the unexpepected seems routine and ordinary to AC, so customers need to get used to.

The food was horrible the flying attendance hardly made any checks and the seats were very tied ..

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

I appreciated the flight was on schedule but the crew told us that the flight would be delayed because of an air craft queue to take off. Instead of us arriving at 11.55pm, we were in Toronto at something past 2am which was a massive disadvantage on my part.

For such a long flight they should offer tea or coffee in between two meals.

No seat assignment . Last on board . Though I would not receive any boarding pass

last minute was rebooked. This rebooking made me miss my connection, added a stop in my itinerary without my approval, and had me arriving 10 hours later to my destination...for a delay that was 2 hours. To boot, my final flight from London to Athens booked me in a middle seat, where I originally booked all aisle seats. This was incredibly uncomfortable for a 24 hour journey and made me incredibly upset.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.

The flight left over 2 hours late and caused me to miss my connecting flight. Consequently, I missed my cruise ship out of Barcelona. The cost associated with this miss was as follows: Airfare to Sicily Italy to get on the ship TWO days late - $232.30 Taxi from Airport to hotel $35 Dinner at hotel $38 Hotel in Barcelona - $208 Taxi from Sicily to hotel $70 Hotel in Sicily - $148 Prorated time missed on cruise $ 1,143
