Fly from Washington DC to San Francisco for just $251 round-trip, including taxes on US Airways. A sligthly higher fare of $254 round-trip can be found on American and Southwest, although they are more scarce.
Travel is valid any day/week, when available, through March 6, 2015. Travel around peak holiday times will have higher fares, but we were able to find some off-peak Thanksgiving travel dates departing Washington DC Dulles (IAD) on November 24 and returning from San Francisco (SFO) on December 3.
