November is a transitional travel month for Atlanta to Southern California trips. Outside of the Thanksgiving peak, travelers can find competitive ATL to ONT flight deals, especially midweek. Expect fall to mild early-winter weather on arrival and variable fares tied to holiday demand. Use fare alerts and flexible date searches to capture savings.
Arriving at Ontario International Airport (ONT) in November gives travelers convenient access to the Inland Empire and many Southern California attractions. With typically mild weather and efficient airport operations, ONT is a cost-effective alternative to LAX for many Atlanta-origin travelers. Plan your ground transfer and car rental in advance for the smoothest arrival in November.
