Oakland International Airport (OAK) is 4.6 miles (7.4km) from the city center of Oakland, California, and one of three airports serving the San Francisco Bay area.
Although not as popular with tourists as nearby San Francisco or San Juan, oak tree-lined Oakland has an interesting and diverse mix of cultures, with more than 100 languages spoken throughout its suburbs.
Popular with low-cost carriers, the airport saw a boom at the end of the last decade and is currently undergoing a much needed multi-million dollar upgrade to its two terminals. There are flights to Oakland International Airport mainly from destinations across the US. The busiest routes are those to major Californian cities as well as Phoenix, Las Vegas, Seattle, Salt Lake City and Portland. Terminal 2 is used exclusively by Southwest Airlines, with Terminal 1 used by all other carriers.
