A:

There are about 10,600 miles between Sydney and London. Keep in mind that this is the flying distance, so the distance is in a direct path from Sydney to London.

The distance is approximately 17000 kms. However flying distances vary depending upon the routing and airways used on the day by the airline concerned. No airline can fly commercial services non stop LON to SYD. An intermediate port such as SIN or BKK or HKG or KUL or DXB must be used.

Routing - if you travel one stop via BKK or SIN or HKG the flying distances all vary.

Airways - these are the flight tracks used by carriers between any 2 airports and the distances can vary significantly on long sectors where a number of optional airways can usually be selected.

A routing LON to SYD via BKK is approx 17080 kms but that is the "great circle" distance ie the shortest point to point. The actual flight distance depends upon the actual airways used by the airline on the day. For example there are a number of different airways that can be selected between BKK and LON and there are significant length variations in these.
