LHR-bound flights are the slower direction by about 90 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.

Time zones and jet lag

LHREurope/London — UTC+0 now; UTC+0 standard time, UTC+1 during daylight saving time
HKGAsia/Hong_Kong — UTC+8 now; UTC+8 all year (no daylight saving time)
DifferenceHong Kong is 8 hours ahead of London today; +8 h in January and +7 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying LHR → HKG. Your body clock has to move 8 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 8 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.
