Airline reviews

I normally love Korean Air, but this trip was not great. We boarded the plan and were settling into our seats. My son and I use these leg swings and we used it on the trip over to Cambodia, but on the way back the flight attendant very rudely told us we could not use it and that it was against regulations. I asked to see the regulation, but never saw it. The food on this trip was horrible as well, Even my son's kids meal was disgusting so we didn't eat anything on the flight. Thankfully we brought snacks. Entertainment - what happened to the games?

Plane took off on time and I had the whole row to myself!

It was a great experience in all aspects including passengers are respectful to each other. I will consider to fly with Korean Air again in the future.

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.

They could have had more up to date movies/better choice of music.

Will try never to fly Delta international again. Flight delayed and staff completely inept in dealing with it. Would not communicate, rude, completely disorganized. Once we reached Seoul the staff there had no idea what to do with us and led us around the airport from one pointless line to another. They were clearly not told how to manage the situation even though they had hours to make a plan. Never again.

On time and flight crew are always so happy to help and always smiling unlike other airlines.

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.

The airplane very small , no space for put my carry on , they tell me loads my carry on I thought they will load my carry only Seattle to San Francisco but when I get off airplane at San Francisco they just tell me load my bags from Seattle to Bangkok Why they don’t tell me before load . I told them I don’t want load my bag from Seattle to Bangkok , because my carry on had medicine. Why crew from Seattle don’t help me , they only told my go to tell luggage claim Delta

Paid $150 for the extra leg room at the door seat for 2 passengers. It was not worth it because it was noisy the whole time because of being near the food prep and the bathroom also there was no under seat storage and the stewards kept harassing about having a bag under our feet miserable. They ought to give you a discount for taking that seat.

Overall, very pleased with this flight. Boarding could be better because boarding was announced without a microphone so people didn’t know to line up until we heard the staff walking around to announce it. Also, had to stand in line for 10’ before we started moving. My husband who is impatient and cannot stand for too long did not like this. The rest of the flight- crew, food, and entertainment were very good.

Boarding was too soon because we arrived 10’ after boarding began and they were already giving ‘final call’. We just made it. We were at gate 35 minutes before the flight. Also, the departure communication board did not list the flight at all so we didn’t know boarding had already started.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

The flight crew and attendants are very professional and polite.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

VN661 flight, the A321 seats are starting to show heavy sign of wear and tear

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

It's basically 15 hours with an airline in economy class. There's really not much of anything that could have been done better unless I had a first class ticket. Cathay Pacific does excellent work, with a very professional, friendly and attentive crew. It's literally the only airline that I will fly to Southeast Asia.

Leg room wasn't that great. Other than that it was a good flight

Great entertainment system, the seat is a bit old style needs refurbishment

Boarding at the airport was not well managed. Otherwise, had a good flight sitting in the first row (which I paid for). Crew was pretty friendly, and flight was smooth.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

Both my husband and I ordered the fish for dinner and we both got sick and throwing up on the plane. I don’t think the seafood was handled properly and I for sure will not order fish the next time around.

The flight was delayed for half an hour, hope this can be better

Flight stewards were sometimes short when passengers made requests at the same time. The requests were simple but a smile & a remark of "I'll get to you soon" instead of a curt & passing "Wait a minute." Flying is not cheap & good manners should be a given when taking care of people cramped in seats for longer than ten hours. The food tasted great but doesn't look appetizing. The mid-meal break food or merienda were great in the last two flights I was on.

The check in staff were fantastic. So so helpful and nice.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

Service was good but food needs maybe it’s just me Cause I am a foodservice supervisor more menu Sampling to get better quality when packed to be reheated . Vegetables are already dark and over cooked and breaded entrees are not the best choice I guess . All airlines meal service doesn’t appeal To me.Cause this trip I’ve used 4 different airlines and nothing good in all of them food wise. Thanks

Overall it’s very acceptable I will gave an A.

They were two hours late!! Threw everything else planned off.

Uncomfortable seats for international flights. No usb charging yet they want you to use your device for entertainment. Very poor.

Continual rescheduling of flights, inflight entertainment system did not work, staff not pleasant to interact with.

Checking in was okay but boarding a little bit slow
