HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

business class is old but still done very well by the team.

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

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 :(

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

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.

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!

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

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

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...

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.

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

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

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

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.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

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 :(

You’re in the three parts of my life, the China Eastern air crew remembered and wish me happy birthday. I was given pastries on two different occasions and a complementary drink. The stew is wish me happy birthday and gave me a birthday card. Everything was first class. Thank you.

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency
