It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

Coming back to America was a peaceful flight everyone and everything was perfect

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

it was a great experience as far as business class.. but I have had better meals and wine on other airlines.. that said.. the price was a great value for what I got in return.. crew made the difference.

Check in process at the kiosk, crew in flight and overall comfort was good. Food selection could have been better. Flight from Hong Kong to Los Angeles did not have any vegetarian main course option, it was either sea food or chicken. Being a vegetarian I could only eat yogurt and fruit. Most international flights have one vegetarian main course dish which I found missing in Cathay Pacific menu.

Great. Efficient boarding process with the face recognition. Plenty of cabin space for luggage.

They ran out of food and were offering random food to passengers.

Short staffs, I ask stewardess to bring me cognac twice during dinner but they didn't bring it!

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

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Overall I had good experience with China Southern airline. Nothing to claim. I hoped they could improve the meal quality that is.

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 connection between LA and Atlanta was too much stress

Terrible boarding experience,,food is very poor that I I . Never going book this airline again.

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

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.

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.

Not good - chair back could not move back for premium economy. Not worth the price

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

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

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 !

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

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.

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!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

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.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

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
