FRA-bound flights are the slower direction by about 20 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

FRAEurope/Berlin — UTC+1 now; UTC+1 standard time, UTC+2 during daylight saving time
ISTEurope/Istanbul — UTC+3 now; UTC+3 all year (no daylight saving time)
DifferenceIstanbul is 2 hours ahead of Frankfurt today; +2 h in January and +1 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying FRA → IST. Your body clock has to move 2 hours earlier, like an eastward trip. A shift this small rarely causes much jet lag; most people feel normal within a day or so. Flying the other way, the shift is reversed.
