ICN-bound flights are the slower direction by about 90 minutes in our estimate: the route runs partly 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

DFW	America/Chicago — UTC−5 now; UTC−6 standard time, UTC−5 during daylight saving time
ICN	Asia/Seoul — UTC+9 now; UTC+9 all year (no daylight saving time)
Difference	Seoul 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 → ICN. 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.
