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

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Going through security a second time to get on the next Korean Air flight was utterly ridiculous and unnecessary. We were in a International secure area.

Always fly with Korean Airlines. Best service great food. Nice and clean as always.

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

Boarding was good, was able to get on early and get settled in . Loved the glass of wine before take off. Once in the air the service was amazing, from the snacks, drinks and the food was good. The flight attendants were very good and attentive. Love flying with Delta..

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

On 2 different flights the wifi was horrible and there was no drink or snack service.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

Flight delayed then cancelled then gate changed two times then baggage lost.

My flight was canceled minutes before boarding started. It took three hours to get rebooked and it was on another airline overnight with another stop added. All I got was two $15 food coupons.

The plane is extremely loud and there’s no place to charge devices.

Not great to be very honest. Our flight was delayed after we sat at the airport until 15 minutes after we were supposed to leave . We were then notified the plane was being worked on “and the parts were out in the ground and still not finished .” Even though the work started the evening before and they knew it wasn’t fixed. . Then we were told it would be a 1:15 pm boarding time so we waited then at 1:45pm we were told it would be an 11:15pm boarding . It was changed to and 3:55am boarding the next morning . We lost out on a day in Hawaii and a night of our VRBO rental.

Safety record impeccable and important since flying many hours and thousands of miles over ocean.

Love the food service and attentiveness of the crew. Could have wi-if on flight

My seat assignment was disappear even I had chosen my seat next to my husband at making reservation. And also the touch panel on my screen was broken so I could have limited entertainment during the long flight.

My tray was broken and instead of being moved I was provided blue tape.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

The late departure Of two hours waitresses, immature, and gossiping

Crowded plane but it flew on time and had friendly staff

We had a good flight, service was good and lots of leg room. Service was good and the staff were friendly.

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

It was upsetting that the flights were canceled but that was due to weather. I did not receive any vouchers for food or a hotel stay when I was forced to spend the night in Montreal. I was also upset when my seat was changed many times.. The plane seemed old with a non-functioning screen and loose side pockets.. All in all in need of updating. On the positive side, the staff in areas was friendly and helpful.

Lost my bag. My first ever flight with them that they forced me to gate check my bag on, due to them having a 30 year old plane with small carry on bins, and they lost my bag. Never again.

United force you to download their App to do the check-in.

The flight got canceled multiple times and we had to drive their to reach midnight for our next morning interview. Poor and unriable experience. Now have to ask for a refund since we didn't need their rescheduled flight three days later.

Short flight, crew members were very nice, so much so I'll take the return flight next weekend
