TCF
My crystal ball says that in a couple of years time, Australian Airlines (not mainline QF) will operate Sydney to Vancouver non-stop using either Airbus A340-500's or B777-200LR's. This of course will be after AUZ open their "southern base". Stay tuned for other destinations such as Athens (non-stop). QF has non type specific options with Airbus which could be converted to A340-500's.
