Delta Air Lines typically offers the most nonstop flights between San Francisco International Airport (SFO) and Hartsfield–Jackson Atlanta International Airport (ATL), leveraging ATL as a primary hub; this often means greater schedule flexibility and competitive fares in November. United and American Airlines provide one-stop and occasional nonstop options via their hubs (DEN, DFW, ORD), which can be useful for loyalty benefits or points redemptions. Southwest may provide lower-fare options from alternative Bay Area airports like Oakland, with different baggage rules and fare structures. Compare seat options (economy, Comfort+, first/business), baggage allowances, and frequent flyer benefits; for business travelers, Delta’s multiple daily nonstops and premium cabins are often the most convenient in November. Check each carrier’s November schedules and promotions to find the best balance of price and convenience.
