Which Bart Lines Serve the SFO Station
At SFO, the Red, Yellow, and Green lines all stop, though not every train on a given line extends to the airport. The Red Line runs between Richmond and Daly City, the Yellow Line between Antioch and SFO, and the Green Line between Berryessa and Daly City. This multi-line access increases flexibility, but it also means that travelers should confirm the destination and line on the train front before boarding, as not all trains that reach SFO continue onward or originate there.
Line Availability Nuances
- Red Line: Serves SFO on routes that connect Richmond and Daly City; some peak trains may terminate or originate at SFO.
- Yellow Line: Direct Antioch–SFO service; a common choice for east Bay travelers heading to the airport.
- Green Line: Serves Berryessa and continues to SFO, generally with fewer stops, which can make trips faster within the San Mateo County area.
Operating Hours and Frequency Considerations
Service typically begins in the early morning and ends shortly after midnight, though exact first and last train times vary by line and direction. Weekday headways are generally more frequent during rush periods, with waits of roughly 10 to 20 minutes between trains, while evenings and weekends often see intervals of 15 to 20 minutes. Travelers planning early departures or late arrivals should check the current timetable for the specific line and direction to avoid unexpected wait times.
Planning Around Service Changes
BART occasionally performs maintenance, track work, or system upgrades that can alter weekend and holiday schedules, reduce frequency, or temporarily affect station access. Before travel, it is advisable to review service advisories on the official BART website or app and to factor in extra time for connections, especially during holidays or major events at the airport.
