From YVR, DUB and NRT/HND would be just about in range (depending on winds, ETOPS, etc.). YVR-BOG and YVR-PTY direct flights are probably the most likely opportunities outside US/domestic routes though, and both less likely than connecting eastern cities with Europe I would have thought. I think our best hope from YVR is guaranteed lie-flats to YYZ/YUL and maybe EWR/BOS/ORD etc.
