✈️ Flight Guide: San Francisco (SFO) → New York (JFK)

For December travel from San Francisco International Airport (SFO) to John F. Kennedy International Airport (JFK), arrive at least 2–3 hours before a domestic nonstop and 3 hours for international connections when holiday crowds are heavier. December brings increased passenger volume, earlier security lines and occasional weather-related delays, so factoring extra time for BART, parking shuttles, or rental car returns is wise. Check airline notifications and enroll in TSA PreCheck or CLEAR to shorten wait times.

The busiest days are typically the Wednesday and Thursday before Christmas and the weekend following Christmas as travelers return home. Peak travel also occurs around New Year's Eve and New Year's Day, which can drive up fares and reduce seat availability on nonstop SFO to JFK routes. Book early and consider flying midweek or taking red-eye flights to avoid the peak crowds and higher prices.
