What airline are you referring to when you say "a China Airline plane": China Airlines? Air China? China Eastern Airlines? China Southern Airlines? Cathay Pacific? Eva? China Xinhua Airlines? Hainan Airlines? Yangtze River Express? Shanghai Airlines? Xiamen Airlines? Shenzhen Airlines?
You'll also have to tell us what equipment you're flying on, and possibly even the route (domestic vs regional vs international interior configurations).
