SFO-bound flights are the slower direction by about 60 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.
| Great-circle distance | 4,152 km · 2,580 mi · 2,242 nmi |
|---|---|
| Initial heading | 282° (WNW) from JFK; 70° (ENE) from SFO |
| Farthest from the equator | 42.0°N |
| Crosses | neither the equator nor the 180th meridian |
| Share of the longest possible trip | 21% of the 20,015 km to the far side of the Earth |
| JFK | America/New_York — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time |
|---|---|
| SFO | America/Los_Angeles — UTC−7 now; UTC−8 standard time, UTC−7 during daylight saving time |
| Difference | San Francisco is 3 hours behind New York today. |
Jet lag, flying JFK → SFO. Your body clock has to move 3 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 3 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.
