Flying the other way?Paris → San Francisco
Flying from San Francisco to Paris
The flight from San Francisco (SFO) to Paris (CDG) covers approximately 8,962 kilometers (5,569 miles) based on the great-circle distance between both airports. This is the shortest theoretical path over Earth's surface, though actual flight paths may be slightly longer due to air traffic routing, weather avoidance, and airspace restrictions.
The estimated non-stop flight time is 10h 52m to 12h 16m, assuming a modern jet cruising at approximately 850 km/h. This gate-to-gate estimate includes time for taxi, takeoff, climb, cruise, descent, and landing. Actual duration varies based on wind conditions — particularly the jet stream — aircraft type, and airport congestion at both ends.
Paris is 9 hour(s) ahead of San Francisco. Travelers crossing 9 time zone(s) eastward can expect severe jet lag, with full circadian adjustment typically taking about 7 day(s).
Since you're traveling eastward, your body clock needs to advance — meaning you'll need to go to bed earlier and wake up earlier than feels natural. Strategic morning light exposure at your destination is the most effective way to accelerate this adjustment.
