Yes — BART Yellow Line from SFO is genuinely excellent value. USD 11.05 (Clipper Card or contactless) to Powell / Civic Center / Embarcadero stations in 30 min, every 15-20 min. For solo travellers + Downtown SF / Union Square / SOMA hotels: BART beats taxi/Uber on every metric except door-to-door.

Tech-conference weeks — does it really affect transfers?+
Yes, materially. Apple WWDC (early June, ~5 days): Uber surge 1.8-2.5× during evening peak + 5-15 min wait at SFO. Dreamforce (Salesforce, mid-September, ~4 days): peak surge 2-3×, taxi queues 30-45 min, hotel-curb queues longer. Apple Special Events (Sep/Oct): 1-day surge. Pre-book transfers 2+ weeks ahead during these weeks, or take BART (unaffected).
SFO vs OAK vs SJC for arriving connections?+
SFO: largest, all international long-haul, 21 km to Downtown SF, USD 50-80 cab. OAK (Oakland): 35 km east via Bay Bridge, cheaper Southwest + JetBlue flights, BART access via Coliseum/Oakland Airport. SJC (San Jose): 60 km south, best for Silicon Valley business arrivals (Apple, Google, Cisco), lower fees so cheaper flights. For Downtown SF: SFO wins. For East Bay: OAK. For Palo Alto/Mountain View: SJC.
Late-night SFO arrival — what runs?+
BART: runs until midnight weekdays / 21:00 Sundays (Sunday last train is a notable limitation). For Sunday arrivals after 21:00: no BART option. SamTrans bus: limited service after 22:00. Uber/Lyft: 24/7 but surge typical 23:00-02:00. Yellow taxi: 24/7 at SFO taxi stand, queue can hit 20-40 min late at night. For arrivals after 22:00: pre-book transfer for guaranteed pickup.
SFO BART luggage — is it feasible?+
Yes for 1-2 medium suitcases. BART trains have luggage space at car ends. Stations have escalators + elevators at SFO + most downtown stops (Powell, Embarcadero, Civic Center). For 3+ pieces of large luggage or oversized items: taxi/Uber easier. Powell Station has stairs-only at some street exits — Embarcadero + Civic Center are step-free.
How long is SFO to Silicon Valley realistically?+
Palo Alto / Mountain View (where Apple, Google, Stanford are): 30 km south on US-101. Off-peak: 25-35 min, taxi USD 70-95. Rush hour (07:30-09:30 + 16:30-19:30): 45-75 min easily. For Silicon Valley arrivals: consider San Jose Airport (SJC) — 25 min vs SFO's 30-45 min, and SJC fares often cheaper.
