The recently approved BART rate hike takes effect July 1, and that means huge increases for BART riders to SFO. Systemwide, fares will spike 6.1%, an average of .30 cents per ride. But passengers using BART to SFO will be hardest hit. The one-way SFO premium charge currently set at $2.50 will jump to $4.00, that's in addition to the base fare. So come July 1, BART riders can expect to pay about $8.10 from downtown San Francisco to the airport.
