The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

I have difficulties to book wheelchair for my parents returned flight

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

Food could have been better. Too many passengers getting up and down all the time.

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

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

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The only thing that could have been better, is that the food trays get left way to long after a meal. We had a snack 8 hrs into the trip, and they left us with the boxes and cups for way too long. It is not fun being trapped in your seat unnecessarily

There was not enough food for everybody. Some dishes were missing.

Same problem place in the middle so small Im 1,85 m so not good 👍

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

Stewardess was attentive and was actively roamin to check the passengers on the biz class

Boarding was excellent except they did last call 30 minutes earlier .

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Small plane with only two lavatories at the back. You must have a good plan to use it before or after the meal, if you make a bad decision, you will end up with standing in front of the toilet for a while till the food carts empty. The good thing is even there’s a slightly delayed, the plane is still arriving on time which is superb!!

The only personel that smiled at all were the flights attendants. Desk agents, lounge people none of them had a smile or even a hello. They were like dealing with dead fish. Again flight attendants were good. All other personnel looked like they didn’t want to be there or help.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

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.
