About this corridor

Flying from San Francisco International

San Francisco International is United's main Pacific hub and Alaska Airlines' largest non-Seattle base. Four terminals form a single ring connected by the AirTrain shuttle, with BART running from the dedicated airport station directly to Powell Street downtown in around 30 minutes for $10. Heavy fog from May through August causes chronic morning delays — book mid-day departures during summer where possible. International long-haul to Asia and Europe is the deepest on the West Coast.

Arriving in San José

Juan Santamaría International serves San José, Costa Rica's capital, 17 km west of the centre. Tuasa bus runs to downtown San José for 690 CRC; taxis cost $25–$30. Fares from US Pacific and Texas hubs peak December–April (US winter demand) with cheaper rates in the May–November green season. SJO is the gateway for Manuel Antonio, Arenal and the Pacific coast resorts; LIR (Liberia) is closer to Guanacaste's Pacific beaches.
