For December travel from Charlotte Douglas International Airport (CLT) to San Francisco International Airport (SFO), the best time to fly is mid-week (Tuesday–Thursday) outside of holiday peaks.

Nonstop flights from Charlotte Douglas International Airport (CLT) to San Francisco International Airport (SFO) save time—typically 5–5.5 hours—and reduce the chance of missed connections, which is an advantage during December holiday travel.
