✈️ Flight Guide: Jacksonville (JAX) → San Francisco (SFO)

October can be a busy travel month due to regional events. In Jacksonville, college football game weekends (notably the annual Florida vs. Georgia matchup hosted in Jacksonville some years) and local fall festivals increase demand at Jacksonville International Airport (JAX). In the Bay Area, San Francisco Fleet Week typically occurs in October and draws visitors to San Francisco, impacting arrival traffic at San Francisco International Airport (SFO).

If traveling in October, book flights and hotels early, expect heavier road and terminal traffic on event dates, and add time for connections. CTA: Check event dates for October and book flights and ground transfers from JAX to SFO early to avoid sold-out services.
