And (perhaps unlikely, but worth asking) do you want to fly both ways, or fly there and come back by train or cruise ship. Sounds dumb, but I'm planning on a one way trip on the Trans-Mongolian railway (London - Brussels - Moscow - Ulan Batoor - Beijing and maybe on to N Korea as well) with a first redemption back from Beijing. Not a honeymoon, but you could combine your trip with a top notch cruise for the outbound or return...
