Air China is Certified as a 3-Star Airline for the quality of its airport and onboard product and staff service. Product rating includes seats, amenities, food & beverages, IFE, cleanliness etc, and service rating is for both cabin staff and ground staff.
“The newer aircraft in Air China’s international fleet offer a reasonable product and seat standards, but quality is lower on aircraft used for domestic flights. IFE programming is poor, and onboard catering is quite inconsistent. Cabin staff service is efficient (with poor English language abilities), and below standards of other Chinese airlines. Newer domestic lounges are fair, but international lounges need improvement.”
