Wonder if they've considered a CX style SIN-YVR-EWR or SIN-YVR-ORD or something like that? Would the 77W have the legs to do YVR-SIN non-stop economically? It is slightly shorter than HKG-JFK, but wouldn't use a polar route so could be challenging westbound?

Noting SIN-SFO shorter than SYD-DFW and only slightly longer than DXB-LAX, yet yields don't seem to be good enough to support ULH using A380.
