Pack layered clothing for November travel: cool mornings in San Angelo and temperate days in Ontario. Bring a carry-on with essentials in case of delayed checked luggage during holiday surges. For Thanksgiving travel, consider flying mid-week and returning mid-week to avoid peak crowds and higher fares. Reserve parking, rental cars, and rides in advance—Ontario Airport rental counters and on-site parking can fill quickly during Black Friday and holiday weekends. Use travel insurance for higher-risk dates and enroll in airline loyalty or fare-lock programs to access flexibility. Include keywords such as "November packing list SJT to ONT", "SJT ONT holiday travel tips", and "avoid delays SJT ONT November" while planning.
