Traveling from San Francisco

Southwest Airlines is proud to serve San Francisco International Airport.


It’s easy to bid Golden Gate City goodbye by boarding a flight at San Francisco International Airport. Just hop on the BART and make your way to your terminal. Of course, if you own a car you can park and fly, and hired cars are always an option.


Life in the City by the Bay has a unique cadence, and it’s certainly alluring, but feeling the vibes of other metropolitan areas is important. Trade the Golden Gate Bridge for one of the bridges in Chicago, which happens to boast the most inner-city bridges of any U.S. city (who knew?). Ditch the Pacific Ocean for the Atlantic with an East Coast excursion—New England or states that consider themselves the South, your choice. True southern comfort awaits in a number of destinations to which Southwest flies, but if you elect to stay on the West Coast, that’s cool. Oregon and Washington state deserve love, too.
