HND-bound flights are the slower direction by about 115 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 | 10,378 km · 6,448 mi · 5,603 nmi |
|---|---|
| Initial heading | 317° (NW) from DFW; 45° (NE) from HND |
| Farthest from the equator | 55.1°N — the path arcs north of both airports |
| Crosses | the 180th meridian (International Date Line area) |
| Share of the longest possible trip | 52% of the 20,015 km to the far side of the Earth |
| DFW | America/Chicago — UTC−5 now; UTC−6 standard time, UTC−5 during daylight saving time |
|---|---|
| HND | Asia/Tokyo — UTC+9 now; UTC+9 all year (no daylight saving time) |
| Difference | Tokyo is 14 hours ahead of Dallas–Fort Worth today; +15 h in January and +14 h in July because daylight saving time starts and ends on different dates (or not at all). |
Jet lag, flying DFW → HND. The clock change is 14 hours, but to your body that is a shift of 10 hours the other way. Your body clock has to move 10 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 10 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.
