It was good but n it to the same standard as London to Singapore

a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

It was very good experience on board to Sydney with SQ.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Once again the meal served was delicious - we got chicken rice

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

55 min transit, not sure how they planned to make it work

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The vegan oriental option was disappointing. The regular vegan option was okay but we've had better.

I was mid plane and they were already out of the main beef entree....ugh!

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.

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.

The economy seats are incredibly tight. A large percent of the traveling public will not fit. I will not fly Cathay again because of this. You are literally squeezing passengers for profit. The CEO should fly some economy flights.

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

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!

There is very little in the title" Premium" in the Economy experience with Cathay, Melbourne to Hong Kong. The seats are uncomfortable and the cabin with outdated 1990's decor and trim. The food service was sloppy and the leg room providing little to no advantage over regular economy seating. Infact, the Sunday flight was not fill occupancy and I would have done better saving the significant additional costs for the PREMIUM ticket and taken advantage of the seating. If you are a regular premium economy traveler of EMIRATES expecting the same experience on CATHAY, you will be disappointed. Emirates far superior.

The aircraft was slightly newer but the food was very bad. Bland and uninteresting. Nothing special at all.

It was good. Just a very long stay over in China to get the second leg to London

We were taking the flight MU 8649 from Shanghai to Osaka and the original boarding gate was 20 and we didn’t receive any notification or broadcast about gate changes, and by the time we missed the original boarding time we check thr electric board and realized the gate was changed to 208 Also the flight was delayed by almost an hour and the crew member didn’t provide any explanation, after we finally boarded the aircraft was very hot, the crew member told me the air conditioning was not working and tried to calm passages down by offering iced water, all of us sat in the aircraft for another 40 mins before it finally took off

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

Wow very impressed by the quality and attentiveness of service of China Southern. Lived the blankets! Will definitely fly with them again. Despite language barriers, a few attendants know enough English to understand our rudimentary Mandarin and respond to basic questions. Although they don’t explain the beverage and meal service on the website or ticketing documents, they offered regular beverage cart and snacks during the beginning hours and end hours of the long, transoceanic flight. A full meal at the beginning and end of the flight as well, and a midflight small sandwich (dinner roll sized) but we weren’t hungry and didn’t try that one. The expectation is that every sleeps during the middle of the flight. We were on a “redeye” departure from LAX with a morning arrival in China, so I don’t know if this service pattern is the same for other flights. The domestic flight we took from Guangzhou to Harbin offered conventional refreshments and meals like a US flight service. Note that they didn’t offer diet sodas. If you like to stay hydrated, I recommend bringing plenty of your own. It is served in small cups like any other drink. You can ask for a bottle but they’re tiny - about 6 ounces.

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!

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Flights were delayed, Food was good but only 1 meal instead of 2.

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

Flew business class. Our luggage was the last to arrive at the belt; 15 minutes after the last bag. Sigh.

I asked for more food as i was too hungry or I probably missed MAS onboard food. Both flight-attendants fulfilled my request by giving me both menus - the Nasi Lemak & the chicken noodles. Both tasted very nice. Thanks Mas. I think asked for skyjuice 5x & tomato juice twice
