ANU-bound flights are the slower direction by about 65 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 | 6,553 km · 4,072 mi · 3,538 nmi |
|---|---|
| Initial heading | 258° (WSW) from LHR; 40° (NE) from ANU |
| Farthest from the equator | 51.5°N |
| Crosses | neither the equator nor the 180th meridian |
| Share of the longest possible trip | 33% of the 20,015 km to the far side of the Earth |
| LHR | Europe/London — UTC+0 now; UTC+0 standard time, UTC+1 during daylight saving time |
|---|---|
| ANU | America/Antigua — UTC−4 now; UTC−4 all year (no daylight saving time) |
| Difference | St. John's is 4 hours behind London today; −4 h in January and −5 h in July because daylight saving time starts and ends on different dates (or not at all). |
Jet lag, flying LHR → ANU. Your body clock has to move 4 hours later, like a westward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 4 days to fully adjust. Shifting later (as here) is usually the easier direction; evening daylight at the destination helps. Flying the other way, the shift is reversed.
