AKL-bound flights are the slower direction by about 45 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 | 10,510 km · 6,530 mi · 5,675 nmi |
|---|---|
| Initial heading | 225° (SW) from SFO; 45° (NE) from AKL |
| Farthest from the equator | 37.6°N |
| Crosses | the equator and the 180th meridian (International Date Line area) |
| Share of the longest possible trip | 53% of the 20,015 km to the far side of the Earth |
| SFO | America/Los_Angeles — UTC−7 now; UTC−8 standard time, UTC−7 during daylight saving time |
|---|---|
| AKL | Pacific/Auckland — UTC+13 now; UTC+12 standard time, UTC+13 during daylight saving time |
| Difference | Auckland is 20 hours ahead of San Francisco today; +21 h in January and +19 h in July because daylight saving time starts and ends on different dates (or not at all). |
Jet lag, flying SFO → AKL. The clock change is 20 hours, but to your body that is a shift of 4 hours the other way. 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.
