Cheap Flights to San Francisco

United's hub plus Bay Area alternatives keep SF fares in check

Flight Deals to San Francisco

San Francisco International (SFO) is United's major West Coast hub, with Alaska, Delta, and American competing alongside it. For value, the Bay Area's secret weapon is its alternative airports — Oakland (OAK) and San Jose (SJC) — where Southwest and budget carriers often undercut SFO significantly. Between hub competition and three airports to choose from, deals into the Bay Area appear regularly, especially in the foggy off-season.

Best Time to Fly to San Francisco

January through March and the September-October shoulder offer the lowest fares. Avoid summer, when fog-season tourism and business travel peak.

January through March is the cheapest window, with transcon roundtrips from the East Coast dropping to $200-280 and West Coast fares far lower. The fall shoulder is also a bargain. Summer brings peak business and tourism demand, pushing fares to their annual high.

Which airlines fly cheapest to San Francisco?

United's SFO hub provides the widest network with competitive fares, while Alaska and Delta keep prices honest on overlapping routes. For the lowest fares, check Southwest into Oakland or San Jose, where budget pricing often undercuts SFO by $50-100 roundtrip.
