Worst experience I have ever had with any airline in over 25 years.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

It was okay overall but the food was very, very bad.

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

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 was okay. Boarding the staff made you feel rushed like we were late or something

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

Same situation saudi lost my pram and car seat and damaged lagguage

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

Apart from chaotic boarding - which I totally understand was outside the control of gate staff. It was comfortable mid haul flight. Well done to cabin crew for their patience and hospitality with largely elderly passengers returning from pilgrimage.

The intettainme is old stuff and difficult to get by WiFi and the chair is not comfortable at all although the staff were excellent but beyond their limited

Overall a great experience, no movies were available. Bags were delivered a bit late. Seat controls were not working well. I couldn't make my bed fully flat.

It is almost 7 hours journey ,you should have provided with TV entertainment and mobile charging

I think the staff was short. Being Vegan, I ordered a custom meal. The meal was not provided both two ways. I assume they forgot. They were short on staff. It was taking for ever to provide service. people were getting restless.

Very poor show. Flight got delayed due to fog in Lahore. This is understandable. However, no arrangements were made for nany hours, once some things was organised, there was no leadership, no support to families with children's, disabled passengers. Took to hotel where it took 3 hours to sort out room allocation, that after finding partner to a minimum of 4 people. Couples were asked to find another couple before room is allocated. After 2 5 Hours of reaching room,return journey started with total chaos, no leadership at airport. Several derours to finally get new boarding passes. Asking the reason why flight was cancelled, the Saudi airline staff recommended using other Airlines in future.Finally boarding nobody inside the aeroplane helping old, illiterate to find their allocated sears. Sort out luggage storage. All the staff stayed in their kitchen areas to let passengers sort out. In-flight service wad good. Overall very poor experience.

It’s very tiring journey with only 3 seats in a row and not good for family of four. Online checkin don’t work and unable to select the seats while going.

Ok, the flight was not full yet I had people on both sided and the chairs were tight. Only 2 kinds of snacks didn’t even have milk for the coffee.

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

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

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!

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.

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 !
