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

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 💜

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

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

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

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 third time to get on the next flight was again utterly ridiculous and unnecessary. We were in a International secure area once again and as far as I'm concerned should not have been put through the gears for absolutely no reason. The United States can get all the information they need from the travel itinerary, there was no need to be forced out of a secure area to personally interview everyone on a connecting flight to find out their US immigration status.

Flight arrived early, fantastic, since it is short flight, no food being served

Flight got canceled without any prior information and it caused lot of trouble

Staff were friendly, and provided great service. The food was plentiful and delicious. Food could have been hotter.

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Serving food took so long . Almost time close to lend. Plus during landing air pressure in cabin cuss ear blocked took long time to unblock.

Emirates is usually on time, but not this trip. Also, during the flight the attendants disappear unless called upon. Very strange. I have watched the quality of Emirates service diminish over the last five years.

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Excellent will be flying again in May with Qatar. to Botswana.

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

On line check in needs a lot of improvement. I tried and gave up.

They use a smaller international plane and quarters are tighter, space smaller, and the flight is still 12 hours, then fight attendants are ruff, food is bad, cherry juice spilled by flight attendant and she comes back to ask why have we not changed yet could it be we didn’t have any clothes to change into and seat is all wet and we had to sit there for 12 hours

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Oh my god! For an13 hour flight they serve you food just one time. Also don’t be thirsty they give you a little small cup of soda to drink. They seem like their goal is to feed you one so they don’t have to be bothered with you. It quite surprise for such a long flight there are several times to eat at least three and the food was well lackluster. The food and lack of offering drinks which were always hot no ice provided.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.
