Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Always on time and flight crew were great. Boarding in Manila was a bit chaotic and disorganized compared to Incheon.

Never had a flight delay issue with Korean Air, that's why I always go with this airline.

Flight crew were very attentive and made this trip a pleasure. Plus the fact that this our first time flying business class.

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.

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

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?

This was an amazing flight. The crew was great. The service was great. The food provided was great.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

Poor links to cathay meaning it's not possible to check in online or reserve seats. Incorrect information provided by cathay regarding check in and transfer at HKG. Delay in flight required is to be escorted / run to make the connecting flight and no opportunity to use the business lounge. Luggage did not make the connection so we arrived in Manchester with no luggage

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

Crew was very good, but could have checked on us when meals were not being served also.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

It was perfect! I've never flown with United before, but I definitely will in the future

I had a cancelled flight because of technical issues going to my destination, and a delayed flight coming home. All told it wasn’t a total bust.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

The business class seat is exceptional. I wish the food is more palatable.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

My wallet was stolen while I was sleeping on the plane.

Good boarding but extremely cold temperature in both flights (60 F!).

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

The most uncomfortable flight I’ve ever been on. I’m only 5,4” and barely had enough room to exist, couldn’t even fully relax my shoulders. Not sure why they bother with snacks. Half a coke and a single cookie?? Wow. Purchasable food looked gross too. Remember when airlines used to treat you like a human being?

Departed Palm Springs over an hour late because there’s only one gate, and it has always delayed by the arriving and departing flight to Toronto and the arriving flight from Vancouver.

I checked a bag and there was only one agent to assist all customers with any issues.

I want to thank Carlos at the Miami AC desk - he was amazing and went over and above to help us out. Thank you Carlos and all the best to you!!! You made our faith in AC feel great! Sincerely, David Cubitt

Flight was canceled due to mechanical issues. After a considerable wait in the queue, Air Canada customer service was very helpful to get us on another flight. I am disappointed to report our rescheduled flight is for three days from now. Three days of extra expenses and inconvenience is unacceptable.
