What does SMF stand for?

  1. San Diego

  2. San Francisco

  3. Sacramento

  4. San Jose

The correct answer is: San Diego

SMF usually stands for "Sacramento International Airport" as known by travelers. Though, don't get confused between SMF and other similar airport codes like "San Francisco International Airport (SFO)" or "San Jose International Airport (SJC)." These smaller airports may be closer to your final destination, so make sure to double check before booking your flight.
