✈️ Flight Guide: Taipei (Any) → San Francisco (SFO)

Check event calendars for both Taipei and the Bay Area when booking to avoid price surges tied to major gatherings.

For January travel from Taipei Taoyuan International Airport (TPET) to San Francisco International Airport (SFO), midweek departures (Tuesday–Thursday) usually yield the lowest fares and less crowded flights.
