Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

Overall things were very good and orderly. The food was very good but I want able to get a second drink very easily, so that could have been better for services. The seats seemed to be lacking legroom but I'm also 6'1" so I'm used to wanting more legroom but the plane seemed smaller then others when it came to legroom. My kids all enjoyed the entertainment as did I so that was perfect!

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

Efficient like all the other flights with them. An outstanding budget airline!

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

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

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 airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

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 .

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

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.

This was my first time ever flying China Eatern and it will not be my last. I was very satisfied with my whole experience and trip. Thank you very much and until soon.

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

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

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

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

How do you run out of beer after one hour of a twelve hour flight?!

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 will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.
