Air China, like China Eastern, are the definition of poor service. Their service perpetuates the truth that Chinese SOE companies have no clue how to operate. The only airline that has even a modicum of world class service is China Southern and even that has the scent of SOE (state owned enterprise). I had my travel agent book me a aisle seat. The aisle seat was confirmed. When u checked in i reconfirmed with the surley check in agent and the confirmed I was sitting in an aisle seat. Guess what he placed me in the middle of 6 people. When I complained to the flight attendant she told me to sit down. Air China never again based on your worst in class service. The check in agent was either deaf, stupid, or had a prejudice against non Chinese. After living in China for 8 years I have a sense that the agent did not like foreigners. What a shameful airline.
