Airline reviews

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.

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.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

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

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

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.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

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 .

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"
Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room poor, and food service is minimal."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
