Any 747s flying from Asia to UK?

I'm not crazy about the 340 seats in UC and am wondering if there are ANY 747s servicing the region. I the "Toolbox" but wasn't able to get it to show me.
Is the 90K miles for one way, Shanghai>London>NYC the best way to pay for this or are there other options. Traveling in May/June. (Options such as with Hawaiian Air, who seems to have a RT deal for anywhere in the world from mainland US for 140K miles, RT! (That's 40K less that VA!!!)
