Pack layers for October travel from Hartsfield–Jackson Atlanta International Airport (ATL) to San Francisco International Airport (SFO): lightweight shirts for warm Atlanta afternoons and a warm jacket for cool, foggy Bay Area mornings. Monitor NFL and college football schedules that can cause weekend surges at ATL, and secure airport parking or use MARTA to avoid congestion. For SFO arrivals, buy BART tickets or reserve ride-share ahead of time for seamless transfers to San Francisco, Oakland, San Jose, or Napa. Keep electronic copies of boarding passes and confirm lounge access if you need quiet work space during October travel. CTA: Prepare early—check flight status, pack a jacket, and set fare alerts for ATL–SFO October flights.
