Oakland International Airport (OAK) is a major commercial airport serving the San Francisco Bay Area and one of the most practical alternatives to San Francisco International Airport (SFO) for Bay Area travelers. Located on the eastern shore of San Francisco Bay in Oakland, OAK is directly connected to BART (Bay Area Rapid Transit) via an automated people mover, making it one of the most transit-accessible airports in California. Strong low-cost carrier service — led by Southwest Airlines — keeps OAK's fares among the most competitive in Northern California.
Oakland International Airport occupies a site on the east shore of San Francisco Bay, approximately 20 miles from downtown San Francisco and 3 miles from downtown Oakland. The airport operates two terminals: Terminal 1 (T1), which handles the majority of domestic operations led by Southwest Airlines, and Terminal 2 (T2), which handles international and additional domestic operations. The two terminals are connected on the landside and share ground transportation facilities.
The BART OAK connector — an automated people mover that opened in 2014 — connects OAK to the Coliseum/Oakland Airport BART station on the Orange Line, providing direct rail access to Oakland, San Francisco, Berkeley, Fremont, and the broader Bay Area BART network. This connection transformed OAK into one of the most transit-accessible secondary airports in the United States and is a significant advantage over driving to SFO.
OAK serves approximately 12 million passengers annually and provides nonstop domestic service to a broad range of destinations. International service at OAK is more limited than SFO but includes routes to Mexico, Central America, and select European destinations.
Oakland Airport opened in 1927 on the eastern shoreline and was one of the first major airports in the American West. In a pivotal moment for aviation history, Amelia Earhart departed from Oakland in 1937 on her ill-fated attempt to circumnavigate the globe. The modern commercial terminal complex developed through successive expansions in the jet age.
For decades, OAK operated in the shadow of SFO, but the low-cost carrier revolution of the 1990s gave Oakland a new commercial identity. Southwest Airlines built OAK into a significant hub, and the airport's lower operating costs relative to SFO enabled it to attract budget-conscious travelers. The BART connector's opening in 2014 further elevated OAK's competitive position by eliminating the shuttle bus that had previously been the only rail-adjacent option.
OAK has two terminals. Terminal 1 (T1) is the primary domestic facility and handles Southwest Airlines, Alaska Airlines, Hawaiian Airlines, and other carriers across its gates. Terminal 2 (T2) handles Spirit Airlines, Frontier Airlines, international carriers, and additional domestic operations. The terminals share ticketing and baggage claim areas on the landside.
The BART OAK connector automated people mover departs from the BART connector station adjacent to both terminals. The ride to the Coliseum/Oakland Airport BART station takes approximately 8–10 minutes.
Southwest Airlines is the dominant carrier at OAK, operating a dense domestic network with high-frequency service to Southern California, Nevada, Arizona, and destinations across the country. Alaska Airlines operates West Coast routes and connections. Spirit Airlines and Frontier Airlines provide ultra-low-cost options. International carriers serve Mexico, Costa Rica, and Guatemala.
OAK provides nonstop service to approximately 40 domestic and international destinations, making it a practical secondary option for Bay Area travelers whose routes are served nonstop from Oakland.
OAK's terminal amenities are functional and practical rather than luxury-oriented, reflecting its low-cost carrier positioning. Both terminals offer dining and retail options, with local Bay Area food concepts represented. Free Wi-Fi is available throughout. The airport's public art program includes installations in both terminals.
OAK is known for being a more relaxed, less crowded airport than SFO — a frequent reason Bay Area travelers choose it when their airline and destination are available. Nursing rooms, pet relief areas, and interfaith spaces are accessible across both terminals.
The BART OAK connector automated people mover is the signature transit connection at OAK. The connector runs from the terminal area to the Coliseum/Oakland Airport BART station, where passengers can board BART's Orange Line to Oakland's 12th Street/City Center station (approximately 12 minutes), San Francisco's Embarcadero or Montgomery Street stations (approximately 25–30 minutes), or Berkeley, Fremont, and other Bay Area destinations.
The BART connector runs during BART operating hours, typically 5 AM to midnight on weekdays with reduced weekend hours. Rideshare services operate from the ground level of the terminal complex. Taxis are available. Rental car companies operate from an on-airport facility.
OAK provides parking in structures and surface lots adjacent to the terminals. Rates are competitive compared to SFO. Economy lots offer lower rates with shuttle connections. The BART connector provides a cost-effective alternative to parking for travelers from San Francisco, Berkeley, Oakland, and other Bay Area locations served by BART.
The BART connector to OAK is one of the easiest airport-to-transit connections in the Bay Area — significantly simpler than navigating SFO's AirTrain and BART combination. From downtown San Francisco to OAK terminal takes approximately 35–40 minutes total, comparable to driving in non-peak traffic.
OAK is particularly convenient for travelers from Oakland, Berkeley, and the East Bay who would otherwise face a long drive around the bay to SFO. Southwest's open seating means check-in timing matters — check in exactly 24 hours before departure for the best boarding group. OAK's security lines are generally shorter than SFO's, making 75–90 minute pre-departure arrival often sufficient.
Oakland International Airport is a key economic asset for the City of Oakland and the Port of Oakland, which manages both the airport and the Port of Oakland cargo terminal — one of the nation's busiest container ports. OAK supports thousands of jobs in the East Bay and contributes to the Bay Area's economy by providing competitive air travel options that serve communities who might otherwise be underserved by SFO's major carrier focus.
The airport's cargo operations are also significant, with Amazon Air, UPS, FedEx, and other cargo carriers using OAK as a distribution point for the Bay Area's logistics network.
OAK is pursuing capital improvements to its terminal facilities and international arrival capabilities. The Port of Oakland continues to study long-term capacity and modernization options for the airport. BART service enhancements and frequency improvements on the Orange Line may further improve OAK's transit connectivity. The airport authority is pursuing sustainability programs consistent with Oakland's environmental commitments.
OAK is a medium hub airport and a secondary gateway in the Bay Area, complementing SFO with a focus on low-cost domestic travel and a direct BART rail connection serving the East Bay and beyond.

Oakland International Airport is the Bay Area's practical, value-oriented aviation choice — a well-connected airport with a BART people mover link, Southwest Airlines' competitive fares, and the genuine advantage of being less congested than SFO. For the millions of Bay Area travelers whose destinations are served by OAK's carriers, it is consistently a smarter choice than fighting SFO's crowds.
Take the BART OAK connector automated people mover from the terminal to the Coliseum/Oakland Airport BART station (approximately 8–10 minutes), then board the BART Orange Line toward San Francisco. The total journey to Embarcadero or Montgomery Street in downtown SF takes approximately 35–40 minutes.
