By plane
The Bay Area has three major commercial airports:
The San Francisco International Airport ICAO: SFO (http://www.flysfo.com/) is on the Peninsula near Millbrae and San Bruno.
The Oakland International Airport ICAO: OAK is across the bay near Alameda and southern Oakland.
The San Jose International Airport ICAO: SJC is at the bay's southern end between Santa Clara and northern San Jose.
All three airports are served by public transportation. The regional metro-rail service BART runs directly to SFO and connects to the commuter rail line Caltrain, as does the San Mateo County bus service SamTrans. The East Bay bus service AC Transit and a connecting bus to BART, AirBART, run to OAK. Santa Clara County's Valley Transportation Authority runs a bus Line 10 connecting SJC with Caltrain and that county's light rail and bus system.
Motorists can reach the Peninsula from OAK by crossing the bay on the Bay Bridge Interstate 80, to the north, the San Mateo-Hayward Bridge Highway 92, to the south, or the Dumbarton Bridge Highway 84, farther to the south. From SJC, drivers can take Highway 87 to US-101 northward, although avoiding 101's rush-hour traffic is often recommended. For longer trips northward, try the scenic, parallel Interstate 280.
