Singapore to Vancouver, in segments < 7 hours

lizbyrd's friend kiyoshi_chan doesn't like taking flights longer than 7 hours, so Liz and I spent some time looking at possible routings for Singapore - Vancouver, in <7 hour segments

Singapore-Dubai-London-New York-Vancouver (23000 km)
Singapore-Townsville-Fiji-Hawaii-Vancouver (18000 km)
Singapore-Tokyo-Anchorage-Vancouver (13000 km)
Singapore-Seoul-Anchorage-Vancouver (12800 km)

Also, Singapore Airlines are still butt-munches for cancelling flights to Vancouver.
