Food and some of crew members' service have room to improve

Waited a long time at JFK to board with no information being readily available.Left about 45 minutes late and it was 2:45 AM in JFK.Nothing todo. Second deck of the Airbus is more comfortable or seems that way because there is less people. Food was OK. The food on secondleg was better as we had ordered it before hand. We thought we had did that on the long first leg but we were told we did not. Cabin crew was generally nice. There are people who lean back when eating as they wait for food to be delivered and know no one will check -- drag. TV selection was awful movies OK. Comfortable all in all.

Not enough seat cushion. Butt was hurting especially on long flight. Not enough movie selection. Entertainment was outdated. Coffee served was cold. Other than that flight was good.

I was very surprised that a meal was given on such a relatively short flight. the meal was FANTASTIC. The crew were also very attentive to our specific needs and we would be happy to fly and recommend your airline to our friends.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It we as a pleasant flight. Good helpful and happy cabin crew. Food was okay, not to write home about. Drinks good. Entertainment okay.. Seat space good , comfort acceptable

Very friendly and attentive flight attendants, good food service. Seat was comfortable. However, the in flight electronics were poor. The screen froze repeatedly; the controller died; the headphones are a hit or miss; the wifi wasn't usable. Very scarce communication before the flight (no email reminder). Almost impossible to understand in-flight communications (audio was very poor).

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

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.

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.

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

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

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!!

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.

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!

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

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

How do you run out of beer after one hour of a twelve hour flight?!

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 :(

2 hours delay on the 1st plane out of the day!!!!!

Someone sat in my seat and this made boarding protracted and unpleasant. The stewardesses kept saying, “it is important that everyone be seated — or we will be further delayed,” but for a long time they did not tell me where to sit. At the end of the flight a baby screamed loudly for several minutes and it took ninety minutes (!) to get through EU passport and customs. We had to stand the whole time in a an overheated room. The seat on the plane was narrow. These things are not all Lufthansa’s fault but they made for a somewhat unpleasant trip.

Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop

The flight on time, flawless check in and boarding process, the crew was very friendly.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.
