ORD-bound flights are the slower direction by about 70 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

ORDAmerica/Chicago — UTC−5 now; UTC−6 standard time, UTC−5 during daylight saving time
CDGEurope/Paris — UTC+1 now; UTC+1 standard time, UTC+2 during daylight saving time
DifferenceParis is 6 hours ahead of Chicago today.

Jet lag, flying ORD → CDG. Your body clock has to move 6 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 6 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.
