Round trip
San Francisco usually runs about $507 round trip from Providence, and this United fare brings it down to $257, a 49.3% discount close to the $211 record low we've tracked. Wine country day trips, the Golden Gate Bridge, and California's mild winter weather make this an easy sell anytime between now and spring. It's one of the strongest price-to-destination combinations in today's batch.
