JNB-bound flights are the slower direction by about 110 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.
| Great-circle distance | 8,310 km · 5,163 mi · 4,487 nmi |
|---|---|
| Initial heading | 118° (ESE) from JNB; 248° (WSW) from PER |
| Farthest from the equator | 37.9°S — the path arcs south of both airports |
| Crosses | neither the equator nor the 180th meridian |
| Share of the longest possible trip | 42% of the 20,015 km to the far side of the Earth |
| JNB | Africa/Johannesburg — UTC+2 now; UTC+2 all year (no daylight saving time) |
|---|---|
| PER | Australia/Perth — UTC+8 now; UTC+8 all year (no daylight saving time) |
| Difference | Perth is 6 hours ahead of Johannesburg today. |
Jet lag, flying JNB → PER. Your body clock has to move 6 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 6 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
