Eastbound (SYD→YVR) is faster than westbound due to prevailing westerlies. Return (YVR→SYD) typically ~15h 30m.
Variables: Wind patterns (jet stream), aircraft (787-9, A350-900), ATC routing, seasonal schedules.
No current one-stop options are faster than the nonstop. Always confirm with airline at booking.
