Getting to SFO
BART (Bay Area Rapid Transit) runs from downtown San Francisco (Embarcadero, Powell St.) to the SFO station and then a free AirTrain shuttle to all terminals (30–40 min from Embarcadero, $10.45). BART also connects Oakland and Berkeley; useful for East Bay travelers. Trains run from ~4am to midnight.Taxis from downtown San Francisco cost $40–60. Ride-hails (Uber, Lyft) pick up in the designated area in the garage and are often $30–50 depending on surge pricing. SamTrans buses serve Peninsula cities. Highway 101 and I-280 are heavily congested during commute hours; BART is faster than driving at those times.

See the On-Time Performance section for the latest delay data at both airports. This shows departure and arrival reliability to help you plan.
Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
At SFO, Southwest operates from Terminal 1 (Harvey Milk Terminal). United uses Terminals 2 and 3. Alaska Airlines operates from Terminal 2. At San Diego, all domestic arrivals use Terminal 1 or Terminal 2, connected airside. Southwest uses the Commuter Terminal and Terminal 2 West; United and Alaska use Terminal 2. San Diego's airport is compact, so transfers between areas take under 10 minutes.
SFO's marine layer frequently delays departures before 10:00 Pacific time. Low-visibility approaches and reduced departure release rates during Category II/III conditions can push ground delay programs before the fog burns off. Midday departures clear the fog window most days. San Diego itself rarely generates weather delays; its proximity to the Pacific keeps summer fog limited to early mornings before 09:00.
The drive on US-101 or I-5 is 500 miles, typically 7-8 hours without traffic. The Amtrak Pacific Surfliner takes 8-13 hours depending on routing. The flight is 1 hour 20 minutes block-to-block. For day trips where a car is not needed at the destination, the flight is time-competitive once airport overhead is added. Southwest's frequent departures and no-change-fee policy make it a practical last-minute option.
San Francisco to San Diego: California's Primary Intrastate Trunk
SFO-SAN is one of the highest-frequency intrastate routes in the US, connecting two of California's major economic centers along the 500-mile coastal corridor. Southwest Airlines carries the largest share of passengers on this route, running 8-10 daily departures. United, Alaska, and Delta also operate the segment. Total daily departures across all carriers reach 20-30. Block time is 1 hour 20 minutes southbound. The route competes with Amtrak's Surfliner and highway travel for short-stay travelers. San Diego's airport, Lindbergh Field, is one of the most constrained in the US by surrounding urban development and a single runway, which keeps SAN delay-sensitive during peak afternoon operations.
Airport Geography and Urban Access
San Francisco International sits 14 miles south of the city; BART connects the international terminal to Embarcadero in 30 minutes for $10.55. San Diego Lindbergh Field is 3 miles from downtown; the MTS Flyer bus (Route 992) runs to downtown in 15 minutes for $2.50. The proximity of SAN to the Gaslamp Quarter and Convention Center makes it one of the few major US airports where walking to a hotel is possible for some travelers. SFO's international terminal connects to the domestic network via an AirTrain circulator, but domestic-to-domestic transfers at SFO are entirely within the landside domestic complex.
