LHR-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 | 8,176 km · 5,080 mi · 4,415 nmi |
|---|---|
| Initial heading | 121° (ESE) from LHR; 327° (NNW) from SEZ |
| Farthest from the equator | 51.5°N |
| Crosses | the equator |
| Share of the longest possible trip | 41% 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 |
|---|---|
| SEZ | Indian/Mahe — UTC+4 now; UTC+4 all year (no daylight saving time) |
| Difference | Mahé is 4 hours ahead of London today; +4 h in January and +3 h in July because daylight saving time starts and ends on different dates (or not at all). |
Jet lag, flying LHR → SEZ. Your body clock has to move 4 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 4 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.
