Cons: "So surprisingly, the cabin was dirty and the seat comfort was below expectation."

Pros: "The cabin crew and the pilots. The flight went smoothly."

Cons: "Aircrew took my carry on away while I was waiting to board saying it was too large; left me without the essential items I wanted during the 19.5 hours in the air and two plane changes. Other people were allowed to keep carry ons bigger than mine so I don't understand why they did this."

Pros: "Nothing"
Cons: "My flight was delayed by 2 hours so I missed my connecting flight in Singapore. There was a huge queue of people who missed their connecting flight cos of an accident in the runway. The airline did nothing to prepare for this situation. It took hours to get another flight organised, communication was non existent and refreshments took ages to come. Airline didn't help with finding a hotel for stranded passengers."

Pros: "Excellent crew services"
Cons: "Entertainment system is rather tired for today’s standard for first tier airlines, in particular the headphone jacks which may not work from wear & tear. It’s a hit & miss whether the sound works or not. Obviously mine didn’t on one side this time. Very frustrating if you are on a long flight and there’s nothing you can do if the flight is full."

Pros: "New plane. Good entertainment. Seat reclined a lot but would not stay reclined."
Cons: "The food was horrendous. Worst airline food I've ever had. Check in and boarding area not great. Very overrated airline."

Pros: "I like the services from Singapore Airlines."

Cons: "N/A"

Pros: "Hard to find lounge for bclass users"

Cons: "I asked for decaf coffee and the attendant totally forgot about my request."

Pros: "The attendants were helpful, smiling and friendly. The entire time We flew with an 18 month old and they came looking for us before he flight to help us carry our stuff on board. They gave her a toy, asked for her name, and checked on us often. They also gave my husband and I an option for early food service so that one of us could help our daughter eat. The movie selection was great. Take off, flight and landing were smooth. And we arrive half an hour early both directions!"
Cons: "Nothing"

Pros: "Great service, great experience."
Cons: "I liked it all."

Pros: "great service. new plane. excellent video system."
Cons: "not much to complain about."

Cons: "None"

Pros: "The plane cabin, the ease of seat selection, friendly helpful cabin crew, quality and choice of food, facilities in the toilets (mouth wash, hand cream, etc), choice of entertainment, early arrival, the price."
Cons: "That I could not afford to travel first class! which must have been marvellous when economy so good."

Pros: "Seating space was very good. Meals terrific"

Pros: "I am still trying to find my bags. I missed my connection and Jet Blue made me stand in a line to get rebooked for 7 hours. Unprofessional, uncaring. None of this was my fault but everyone who represents Jet Blue treated me as if it were. Never again"

Cons: "old facilities"

Pros: "Lots of movie and game options"
Cons: "Staff was slow to tend to my needs (i.e. Water), continually bumped into my shoulder or leg. Would not accommodate moving my seat next to my wife's because a couple wanted to have an entire row to themselves. Very frustrating"

Pros: "nice food, plenty of water, good service, quite comfortable & on board wifi if you need it"

Pros: "Everything"
Cons: "Cabin too hot"

Pros: "The food. The nice crew members. The comfortability and service. The tech and entertainment available."

Pros: "Singapore is #1 in my books. So glad I could get on their airline. The flight was super. The economy cabin was really nice and comfortable. I especially liked all the adapter plug outlets to power my equipment. I just can’t say enough good things about the cabin crew. The Stewardess were very attractive in their uniforms and make-up, not like the old maids United and American has. The cabin crew were extremely helpful and nice. The service was impeccable. The meals were actually pretty good. Course all the alcoholic drinks available was nice. A person could get wiped out pretty easy if not drink responsibly. But not a good idea to drink much cause of the aftereffects after the flight."
Cons: "The headset ear plugs left a lot to be desired. I need to bring my own good set to enjoy the vast selection of music and shows available. My number 1 complaint was the outside row seat armrests would not move up. This makes getting out of the seat into the isle much more difficult than it has to be. Why does it have to be stationary?"

Pros: "SGN-SIN is normally less than two hours. Business class very comfortable. I did not use the entertainment system -- it had trouble starting, by the way. Crew very attentive to passengers' needs."
Cons: "The aircraft had landed on time. Why does it take so long to start boarding? Of course the delay in take-off snowballed, more delays were added circling the airport of SIN."

Cons: "charge a few $ more but serve some food on a 5 hour flight. very cold feeling"

Pros: "On my flight back I got to sit in premier economy and that was amazing !! I want to fly like that all the time! The leg room and space was perfect. The comfort of the chairs recline and foot rest that raised up was great. The big tray table that tucked away was nice. And side pockets for your stuff was great. The comfort of the bigger seats was just excellent and they looked newer. On my flight back from Frankfurt to NYC that was the best flight I ever have taken."
Cons: "The only thing was the food wasn't the best. But I did have Ice cream and that was good. The rice was good and beverages was good. The rest wasn't the best."

Pros: "The crew was very attentive and most good English"
Cons: "The food could have been better and there could have been a better selection of movies."

Pros: "Great crew in business class!"
Cons: "Wifi was terrible, entertainment is below average and angle seats for a 12 hour flight is sub par. The food was so so"

Pros: "The staff and service were both incredible! Thanks CE"

Cons: "Terrible customer service. This is not a good airline."

Pros: "Nothing"
Cons: "Customer service"

Pros: "Economy seats are not comfortable on any airline. I wonder why seats in a car are more comfortable than in an airplane? The staff were very zealous and proficient. They were pleasant and helpful. The food was the best of any airline I have flown. I was very impressed with the biscuits!"
Cons: "I did not like riding the bus to my airplane on the tarmac."

Cons: "It would be appreciated if the movie were more updated."

Cons: "I’m very disappointed with China eastern airlines. Despite making the request during reservation, my mom who has bad knees did not get wheelchair. Staff was very rude and did not provide wheelchair and she had to walk a lot with pain."

Pros: "The flights were on time (including my transfer flight) and smooth. Food was mediocre but nothing worse than any other airlines."
Cons: "Not much maybe just the food but the flight attendants are very nice."

Pros: "The price"
Cons: "Overall experience is not as good as the competition."

Pros: "cheap flight"
Cons: "Don't fly into Shanghai's airport."

Pros: "The crew profesionalism"

Pros: "Everything was perfect! No complaints."
Cons: "I don’t have any complaints."

Cons: "Nothing"

Cons: "They have very cheap earphones. carry your own if you want to listen to anything or watch a movie."

Pros: "Very helpful and courteous air crew"
Cons: "Everything was good and for a short flight Like this the crew made it very comfortable"

Cons: "Shanghai airport needs to be more clearly marked on where to go. Most of it was very confusing, and the airport staff wasn't very helpful."

Pros: "The service was great. Seats barrable."
Cons: "May have gotten sick from the water or food served."

Pros: "Special separate Transfer Van for Business class passengers to board the plane."
Cons: "No Priority Check-in for Business Class at the Airport. We were in line with Economy class passengers. Not in English Announcement at Boarding time. Ridiculous. CHINA EASTERN web site is horrible. When I was booking for seats, only showed 2 available seats and I had no choice. When I boarded the plane there were many empty seats. That is the trick the airlines play."

Cons: "No one to assist my friends enter the plane. No one to help with hauling minor carryon baggage up the outdoor staircase. Very difficult and no offer at all for anyone in a party of six to help. No lift and no one offered assistance in business class to help at all.once on the plane service was outstanding. Passengers in 70s and 80’s and no knowledge of the need to to climb stairs and without any assistance. Attendants watched the elderly struggle."

Pros: "I liked the service from the cabin crew"
Cons: "I hate that I couldn’t use my phone on airplane mode. What’s up with that? I’m not a fan of Airbus. Boeing aircraft are superior"

Cons: "This was by far the worst airline experience I've ever had. This airline almost appears to go out of its way to treat it's customers poorly. The experience starting with check-in is a customer service nightmare."

Cons: "Takeoff delayed by 5 hours. Airlines managers have to be upfront about the cause of delay. Do not make excuses. The immediate truth will serve you well. In this case was it in fact air traffic control saying fog on the ground making landing dangerous. The $20 food voucher help a little."

Pros: "Good meals, attentive staff, and great crowd management."
Cons: "Might be cultural, but the boarding was like herding cats -- the seats are assigned! The DutyFree pickup at the gate makes it supper hard to get onboard and still fit your carry-on. Enforce the carry-on and ONE personal item"

Pros: "The overall service from arrival in Shanghai to arrival in Taipei. Everyone was so helpful and I got good direction from staff because of my language barrier."
Cons: "Just the long wait at the airport but still it wasn't too bad."

Pros: "For the price, I would say it was a very solid flight. Other options cost twice as much and I'm certain they weren't twice as good. Food could have been a little better, but again at the price, there is nothing to complain about. Buy a salad or a snack for the flight with all the money you are saving. The entertain was good but not as extensive as some of my other recent trans-pacific flights."

Pros: "Service on their 777 JFK-PVG is great. CE has an outstanding crew. I just don't understand why other carriers charge 20-70% more for the same business class."
Cons: "Some flights out of PVG require you to board the plane from the tarmac using stairs. Uncomfortable during in climate weather. OK a bit picky."

Pros: "Good! I slept through the whole thing."

Pros: "Seats were comfortable and the selection of in-flight movies was good."
Cons: "Staff weren't very friendly. Also required you to unplug your headphones during takeoff and landing which seems unnecessary. The plane also smelled of smoke."

Cons: "They didn't serve beers except meal times. And, the beers were so warm, not taste good at all. The crew's English level is very poor also."

Pros: "Nothing"
Cons: "I bought round trip tickets for me and my daughter. I am coming from San Francisco and my daughter from siem reap Cambodia (immigrant). I asked online if i can buy round trip for me and one way ticket for my daughter. They said i cant. So i bought round trip. Now i am here in Cambodia waiting to check in with my daughter but they said that my daughter does have ticket as it was cancelled since she was not in the departure flight from SFO. I am suing somebody."

Pros: "The polite and courteous cabin crew."
Cons: "PVG airport. Buses? Really? The waiting area was cramped."

Cons: "We waited nearly two full hours for our bags to be delivered. And no explanation given--at least not that I heard. An agent was sent out after 90 minutes or so, but she gave no explanation, only that the bags were "coming." (She did apologize profusely.) I understand that things happen, but this was a black eye for the airline. Everything else was great."

Pros: "Didn't wake me up when sleeping when meal came Had empty seat next to me"
Cons: "Didn't have enough departure/arrival forms to distribute No wifi No soap in bathroom"

Pros: "airport at China was a little bit more organized and he boarding was smoother."
Cons: "The connecting flight from china to JEJU was delayed, not sure if it was due to airspace but we were in the plane for 45 minutes before it took off. Overall no a great experience"

Pros: "The crew on the plane was very nice"
Cons: "Was delayed 5 hours"

Cons: "I enjoyed the trip from LA to Okinawa, then to China But from Beijing to Shanghai then to USA It was delay and despite I told the staff that my husband is very pro to infection they still put him at last second roll 73 and closed to all little kids some were coughing. There are some area still opened seat. Please don't take me wrong I love the kids but such incident- kids did not put on their seat bell while the airplane were taking off. I had to remind your staff. Some of those parents did sit in between but not paid close attention of their/other kids. Sophia Tse"

Pros: "Plane is new, great service. Overall excellent"

Cons: "The airport was diffulvt to menuvuer."

Pros: "Did not like much. The crew was not the friendlyess. There was a crying baby and a loud women sitting directly behind our seats. The crew did not seem to know how to handle the lady or the crying of the baby. The annoying sound made for an the most uncomfortable flight ever. The crew did nothing accommendate us for the noise. A better seat up front, headphones or something should have been offered with out request! Even an apology for the out of control environment! Me and my mate will never take China eastern ever again! And will advise others to do the same. There were plenty of seats available to be moved too... The food was the only decent thing on the plan. The bathrooms where a mess and again the crew was horrible except maybe one, but that doesn't make up for the other 5 or so members who where suppose to be helping out."

Cons: "They changed the flight schedule during the last few days. Their phone lines don't work, either they don't pick up or all they speak is Chinese. The airport staff is mind-bogglingly uncooperative. They didn't even offer me a hotel for the 21 hours layover I was forced to endure. No one had proper answers; they were just sending me from one desk to the other till I gave up and slept at the airport itself."

Pros: "No wifi. No electronics allowed to use. Even you can't see photos on phone or listen your songs or watch movies."

Pros: "If you can help it, do NOT travel on China Eastern. This is an airline that does NOT care about the passenger and does things the way they are done in communist dictatorships. My flight was from REP to PVG and then to ORD. The first leg (MU514) was delayed by 16 hrs - we were not told straight away about the length of the delay, every 2 hrs they would come up with a take off time and then delay it again. We spent the night at the airport - no food, no hotel. There were measely vouchers for a burger and a drink in the morning. We missed our onward flight and were delayed another 20 hrs in Shanghai. After queueing for hours we were given a hotel. A nightmare."

Pros: "The flight left on time."
Cons: "We had to dump out our water before getting on the plane. They had a place where we needed to either empty out the water bottles, or leave them behind. This was after security. We thought it strange."

Pros: "Good was good"
Cons: "Didn't like having to take bus to plane"

Cons: "People who worked at check in area need to learn better serving to guests"

Pros: "The crew was friendly for the most part. In seat television screens with provided headphones."
Cons: "I was given the wrong gate number. Standing at the gate I was instructed to board with no additional communication that they gate had changed for my flight. If I hadn't asked around, I may have missed my flight."

Pros: "Flight from Chicago to Shangai was delayed four hours. Didn't make connecting flight. Had to take a cab from Shanghai to Ningbo and never completed our flight. The next plane was not due in until 24 hours after we landed. China Eastern did not take care of a hotel stay, dinner vouchers or rental car even though it was their fault that we missed our connection."

Cons: "My flight was delayed more than advertised and no one helped me when I got to Shanghai so I missed my connecting flight. No options were given for a new flight to LA except a flight in 24 hours. Was out up in a HORRIBLE stinky hotel without my luggage because no one could help me track it down (even though I found out later it was in Shanghai). It was the WORST flying experience of my life."

Pros: "The flight was comfortable and cheap."
Cons: "Shanghai International Airport is the main hub for China Eastern and it is not a good airport. The air conditioning sucked and the staff couldn't speak English."
