Weren’t even given earphones to use the entertainment system

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).

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

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

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 & service very good next I will pick up again

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.

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.

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight
