Terminal 1
The larger terminal, used by Alaska, Delta Connection, Frontier, Hawaiian, Volaris, Viva Aerobus and some Southwest flights. All international arrivals clear US Customs and Border Protection here.
Oakland San Francisco Bay Airport (OAK) is the airport for Oakland, California, and the East Bay side of the San Francisco Bay Area in the USA. The Port of Oakland runs it, and until 2024 it was called Metropolitan Oakland International Airport; most travelers still say Oakland Airport.
Southwest Airlines flies the most routes, across California and the West, to Hawaii and to cities such as Denver, Chicago Midway, Austin and Dallas Love Field. Alaska Airlines, Hawaiian Airlines, Delta Connection, Frontier, JSX and Advanced Air add more domestic flights, while Volaris, Viva Aerobus and Volaris El Salvador fly to Mexico and San Salvador. The airport handled about 9.2 million passengers in 2025.
Two terminals stand side by side and are joined past security: Terminal 1 handles most airlines and all international arrivals, and Terminal 2 is used by Southwest. The BART station is across the street, with trains to Coliseum station for the wider BART network.
The airport sits on the bay shore beside Interstate 880, about 7 miles (11 km) south of downtown Oakland. From here travelers head to downtown Oakland and Jack London Square, Alameda, Berkeley and Emeryville, across the Bay Bridge to San Francisco, about 25 minutes away without traffic, or east to Walnut Creek and the rest of Contra Costa County.
