Cheap flights from Boston to San Francisco

When you arrive at the San Francisco International Airport (SFO) from Boston, you'll find a city equally as bustling as the one you just left. Picking up your rental car at the airport is the most convenient option, and you can make your first stop at Fisherman's Wharf for some sunshine and salt air, while recovering from your long flight. You can even find the catch of the day being served at one of the areas restaurants.

Key Facts

For a bit of excitement, take your rental car for a ride down Lombard Street; this steep road has eight tight turns in the space of a city block. After arriving at the bottom safely, you can decide between a visit to Chinatown, or a trip to Alcatraz Island to visit the inescapable prison. You can easily spend a day exploring Golden Gate Park with its Japanese Tea Gardens, numerous museums, concert area, bison paddock and botanical gardens.

Hints and Tips

The flying time from Logan International Airport (BOS) in Boston to San Francisco is a little over six hours.
