JFK-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

CMNAfrica/Casablanca — UTC+1 now; UTC+1 all year (no daylight saving time)
JFKAmerica/New_York — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time
DifferenceNew York is 5 hours behind Casablanca today; −6 h in January and −5 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying CMN → JFK. Your body clock has to move 5 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 5 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.
