🇺🇸 San Francisco → 🇦🇷 Buenos Aires

The flight from San Francisco (SFO) to Buenos Aires (EZE) covers approximately 10,402 kilometers (6,464 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 12h 34m to 14h 8m, 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.

Buenos Aires is 4 hour(s) ahead of San Francisco. Travelers crossing 4 time zone(s) eastward can expect moderate jet lag, with full circadian adjustment typically taking about 3 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.
