Dec. 2007,,,I phoned "Super Shuttle" airport van service ,800-258-3826, to see how much it was from the peninsula, San Mateo county, across the S.F. Bay to Oakland airport,,,and was quoted $110 each way !! And like most airport shuttle companies, they have in the last few years forced their employee drivers to buy or lease the vans they use, plus pay maintenance and insurance !! I have yet to find an airport shuttle company in the S.F. Bay Area that does not unfairly force its driver employees to assume this unfair share of the business burden.
Someone recommended Bayporter Express, 415-467-1800, from mid-peninsula Burlingame to the Oakland Airport ,,,and it is 'only' $40 each way !! Huge savings over the much larger other airport shuttle company. And no additional mandatory driver's tip. Happy shopping !
