IST-bound flights are the slower direction by about 80 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

ISTEurope/Istanbul — UTC+3 now; UTC+3 all year (no daylight saving time)
BKKAsia/Bangkok — UTC+7 now; UTC+7 all year (no daylight saving time)
DifferenceBangkok is 4 hours ahead of Istanbul today.

Jet lag, flying IST → BKK. 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.
