and the elevated walkway above San Leandro Street linking it to the original platform. Both stations for the line feature platform screen doors – a first for the system. The line is paralleled by AC Transit Route 73, which is less frequent during peak hours but less expensive. Routes 73 and 805 provide overnight service during hours that the Oakland Airport Connector - and the rest of the BART system - are closed. Fares On June 12, 2014, the BART Board of Directors voted to set the base fare for travel on the BART to Oakland International Airport AGT system at US$6. The Board left open the possibility that temporary promotional fares could be introduced in the future. In addition, seniors, people with disabilities, and children age 12 and under will be eligible for BART's 62.5% discount. , the line operated with a farebox recovery ratio of 96%. This lower-than-expected revenue, in part due to competition from ridesharing companies, resulted in a net operating cost of US$860,000 between 2014 and 2016. History AirBART On July 1, 1977, BART began a shuttle bus service called AirBART that ran to the airport terminals from street level at Coliseum station (thereafter named Coliseum/Oakland Airport). The shuttle ride took ten minutes and cost 50 cents. AirBART was a joint project of BART and the Port of Oakland, which owns and operates the airport. As with other BART-branded connecting buses, AirBART was run by private operators under contract. It was operated by Veolia Transport (Shuttleport) from 2001 to 2012, then by Ampco until 2014. The diesel bus fleet was replaced by compressed natural gas buses around 2008. At the time of replacement, AirBART ran from 5:00am (8:00am on Sundays) to midnight - approximately matching BART operating hours - with nominal headways of ten minutes at most times. Travel time was estimated as 15 minutes. However, travel times and frequency were inconsistent due to traffic congestion from commuters and Oakland–Alameda County Coliseum events. Passengers were required to pay the $3 fare with exact change or a $3 BART ticket from dedicated fare machines. Because of a dispute between BART and the Port of Oakland about who would pay to modify fare equipment, Clipper Card readers were never installed on the buses. Ridership was about 2,800 per day in 2008, but dropped to 1,900 daily riders by 2014. AirBART service was discontinued on November 22, 2014, when
