Please consider this when using Chinese airlines to compare to others.
Chinese airlines do not need to make a profit. They make money off people like me who operate private airplanes into China. The latest stops we have made in Beijing are up to 50k USD per flight. Part of this charge is actually called an "Airline Compensation Charge", where I have to pay to compensate the Chinese carriers for not carrying these passengers in and out of China.
I flew China Eastern (380) from LAX to Beijing myself a month back. Business class was not even half full. The rest of the plane was about half full.
If you are using Malaysian Airlines as an example of airlines that use the 380 profitably, you may wish to rethink that. Malaysian is basically bankrupt, I would expect to see big changes there shortly. They bought the 380 for the same reason they built a gazillion dollar Formula 1 track. P..nis envy.
That being said, as a passenger I enjoy riding on the 380. It is nice and quiet.
