or at least I couldn't get past NRT coming back from Cambodia through HKG... had to overnight in NRT. I did the routing on CX from NRT that you mention (and had to overnight in HKG on the way over). As I mentioned earlier, the flat-bed is REALLY nice when your travels continue, after a few hours in NRT, to other places. And I get to start the whole trip from Guatemala (usually through our favorite airport, MIA).
