Once you figure out which seats you want, just call Air China and they can do your seat allocation on the phone.
I found that has better and more updated info, also.
I'm sure there's a way to do it online but it may not be worth the brain damage trying to figure it out. For example, on my upcoming flight on Air China from JFK to Beijing, Im flying on the B 777-300 ER but seatguru doesnt have that yet. For example, on my upcoming flight on Air China from JFK to Beijing, I'm flying on the B 777-300 ER but seatguru doesn't have that yet. Seatguru used to be very good but recently I think that they are not getting regular updates. You can get more details on the recommended seats through several web sites.
I find their web site more user friendly than Air China's web site itself. Their seat maps are updated in real time so you can do a dummy booking and immediately see what is available for your flight and the type of aircraft being used. The easiest and best way I have found to see what seats are available and details on the aircraft (type, layout of seats) for Air China is Expedia.
