NRT-bound flights are the slower direction by about 70 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 | 6,136 km · 3,813 mi · 3,313 nmi |
|---|---|
| Initial heading | 300° (WNW) from HNL; 87° (E) from NRT |
| Farthest from the equator | 35.8°N |
| Crosses | the 180th meridian (International Date Line area) |
| Share of the longest possible trip | 31% of the 20,015 km to the far side of the Earth |
| HNL | Pacific/Honolulu — UTC−10 now; UTC−10 all year (no daylight saving time) |
|---|---|
| NRT | Asia/Tokyo — UTC+9 now; UTC+9 all year (no daylight saving time) |
| Difference | Tokyo is 19 hours ahead of Honolulu today. |
Jet lag, flying HNL → NRT. The clock change is 19 hours, but to your body that is a shift of 5 hours the other way. Your body clock has to move 5 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 5 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.
