I upgraded my flight to business and before boarding they told me they will not have food on the flight unless someone declines the food service.

I upgraded my flight to business and before boarding they told me they will not have food on the flight unless someone declines the food service.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Nice staff, only one of the food services had a vegetarian option. Premium Economy was good - big seats and footrest. A little slow bringing welcome drink and often didn’t have the prosecco left on the tray - as though they are discouraging choosing that option. My only complaint is the wine/drinks served in a paper cup - I ordered a cognac on our previous flight and it came in the bottom of a paper cup, wine is poured into the cup like it’s a bucket!

Flight was delayed due to air traffic control and technical issues - power outage happened several time during taxiing in Taipei causing further delay for urgent technical check.

Cathay has always been great. Even allowed some leniency on my baggage weight. I believe they are also on the more leg room side of airlines.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

If there is any negative rating for kayak and also for Cathay Pacific or the dealer I used I would give all of them -1000000000000000 I will never ever use kayak again you scammers you rip me off with everything

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

As a solo traveller, I always prefer to have an aisle seat, but the flight was so full, there weren’t any available. I understand that the seatbelt sign sometimes has to go on if turbulence is anticipated but after the second food service, it was on continuously for about an hour and a half and there didn’t seem to be any turbulence at all! With seats reclined, my fellow passenger in the aisle seat asleep and the seatbelt sign on I felt very trapped, extremely uncomfortable and in desperate need of the bathroom. The positives were that the staff were very friendly, the entertainment was great and we actually took off on time and arrived in HKG earlier than expected.

Very comfortable flights. Not so many new releases in terms of films.

Seats not comfortable. We had requested vegan meal and it wasn’t given.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

The back of the chair - premium economy could not move back - not worth the price

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

Flight canceled, but they didn't notify me. They arranged a nearby hotel and 4 meals for me to stay for 24 hours before I could board.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

Very friendly and attentive flight attendants, good food service. Seat was comfortable. However, the in flight electronics were poor. The screen froze repeatedly; the controller died; the headphones are a hit or miss; the wifi wasn't usable. Very scarce communication before the flight (no email reminder). Almost impossible to understand in-flight communications (audio was very poor).

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

Food no variations only beef of chicken no veggie meals

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

Lost Baggage - very frustrated…learned that bag was never put on plane.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Multiple delays, with no explanation. Caused us to almost miss our connector. The airline made no effort when we arrived in Shanghai to help us make it to our next flight with the same airline.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Staff were uniformly excellent. Padding for premium economy seats was a bit thin. Drinks service was very very good. Food was meh.
