Upgrade to 777!
Our masters up North like the 777 too. I hate to say it but the 747 has had its day as a pax mover.
From ATW:
Air China (CA) will debut its Boeing 777-300ER Feb. 1, on the Los Angeles (LAX)-Beijing (PEK) night flight, replacing a 747-400. CA, which is the only carrier to provide nonstop service between the two cities, doubled the daily service in September. It will go one step further to enhance the route in June when it plans to upgrade the 747-400 day flight between LAX and PEK to the 777-300ER.
