AirBART was a shuttle bus service connecting the Bay Area Rapid Transit's Coliseum Station with Oakland International Airport (OAK). The service was replaced by the new BART to OAK automated guideway transit system on November 22, 2014.
AirBART buses stopped at street level just outside the Coliseum BART station and served both airport terminals with one stop at the airport along the third curb. Buses ran every ten minutes, seven days a week. Service began at 5 a.m. (with 20-minute frequency until 6 a.m.) Monday to Saturday and at 8 a.m. on Sunday, and ran until midnight
At the end of AirBART service, a ride cost $3 ($1 for children 12 years and younger, seniors 65 years and older, and disabled persons). To speed up boarding, AirBART required exact fare to be paid for boarding the bus, a ticket from the AirBART vending machine (credit card or debit card only) located at the terminal AirBART pickup location, or a $3 BART ticket. Payment was deposited into a standard farebox on board the bus. BART recommended that riders not purchase tickets from strangers as they may be fraudulent. Depending on traffic, the ride took ten to fifteen minutes (delays caused mostly by Raider game traffic).
AirBART was a joint project of BART and the Port of Oakland, which owns and operates the airport. It was operated by Veolia Transport under contract. As of December 2009, the AirBART fleet consisted of five Eldorado Axess buses running on compressed natural gas (CNG).
Trips between the BART station and Oakland Airport can also be made on AC Transit Route 73. AC Transit is cheaper at $2.10, with additional discounts for those transferring. Route 73 runs every 15 minutes every day, which is less frequent than AirBART service was. Although Route 73 makes several local stops, total trip time is only slightly longer. The airport connection provided by Route 73 is not emphasized; signage and information is the same as the other AC Transit routes serving the station.
