The flight was delayed and food was averiage - only sandwich. The flight attendants were good and gave outstanding customer service 👍🏼

They forced me to check a bag. When Kayak sold me these tickets I was not informed of carry on baggage weight limits.

Great food on both legs and fast customer service from the stewardesses....

The food was great; the attendants were pleasant. Waiting to onboard felt stressful, as passengers who had connecting flights at SEA had to be verified again for two things before getting a real boarding pass: passport and carry-on luggage weight. The boarding pass issued by another airline (i.e., the first leg of my trip) did not count. The S terminal at SEA was barren, with lots of sensory overloads because every airline was repeatedly broadcasting long lists of names of passengers who had not gone through that verification process. The carry-on luggage weight check seemed futile to me. I saw a woman who opened her over-weight suitcase to move some items into her shoulder bag. She still boarded with two huge bags with her. I assume this check is an endeavor of ensuring fairness of the overhead bin space or optimizing fuel efficiency when gas price is through the roof, but I don't know if either goal is achieved. Nonetheless I respect the crew's dedication to the SOP.

Food tasted like the meat had freezer burn. Another thing all of our 4 check baggage was left somewhere and my oral medication for my diabetes was left in one of the lost luggage..most of the flight attendants did not know how to communicate in English.. the trip was a total nightmare

Staff show very stress with delayed flight more than passenger.

Seats could have been more comfortable, but it was a pretty good experience all things considered

Poor services. Not meet 5-star airline standard. Disappointed with the poor food and drink selections. Cabin crew is not attentive at all. They even skipped me during meal service (not sure if it is intentionally).

All went well with my flight I would recommend this to anyone who asked how my flight was

The crew was great. There was no wifi The cabin temperature got very hot Seat was uncomfortable

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

This flight was a superior flight in all regards. Extremely pleasant experience.

The carry on baggage was collected before boarding without further information where the passengers can collect them . When the flight arrived at Tan son Nhat airport, it was very complicate to find the luggage

It would be better if flight crew can clearly communicate in english. But they are kind and accommodating. Food is good, especially the sandwiches on the self-serving snack trays. They are better than the ones served. Boarding was organized.

The flight crews were extremely professional helpful and courteous. Departure and arrival times were accurate. No delay. Thanks

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

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

They are very helpful and friendly. The entertainment is great with many choices. They will refill your drink and there is plenty of meal service. I’ll fly with them again when I transit Tokyo.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Seats had more space than expected. No recline, that is good.

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Boarding was quick and efficient. The food was very good and they had pictures showing you what options there were to avoid misunderstandings.

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

The flight was canceled due to a mechanical problem. The rebooked flights were snot good. Many complexities. Will not use a third party booking again.

Our flight that was before this one was delayed, and I appreciate that this airline sent a very nice flight attendant to pick us up at the Chicago airport and walked us to the gate. They waited for us, so we didn't miss the flight. That was amazing and outstanding customer service! We appreciate you so much!!

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Flight was delayed for about an hour but overall good experience

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Short. Nice quick flight, appreciated after Munich to DC leg.

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane
