Hong Kong to Sydney (HKG-SYD): nonstop upgrade & award space

Cathay Pacific, Qantas, and Hong Kong Airlines fly nonstop between Hong Kong (HKG) and Sydney (SYD), roughly 40 times a week. Cathay Pacific carries most of this long-haul schedule, so one carrier's release pattern decides when premium space appears, and it is rarely all at once. 2LNR tracks award seats on Qantas across every HKG to SYD date, so you can see whether a seat exists before you move points.

Schedule last confirmed September 6, 2026. Departure times come from 2LNR's schedule data; confirm with the airline before you book.

Showing all 39 scheduled HKG to SYD departures across the next 7 days with service. Later dates are on the interactive map.

Departure and arrival times are local at their own airport, so an arrival can fall on a different local date than the departure; the duration column is the true elapsed flying time. A dash means the airline has not filed that value in the schedule data we hold. Aircraft are IATA equipment codes as filed, and can change up to departure.
