San Francisco to Sepang (SFO–KUL) — Airlines, Schedules & Connections

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.

KLIA Ekspres to KL Sentral takes 28 minutes (RM55). KLIA Transit is slower but cheaper if you're stopping at intermediate stations. Both depart from the basement of the main terminal. KLIA2 (AirAsia) has its own station on the same line.

Taxis from KLIA to central KL cost RM70–100 using the fixed-rate coupon system at the taxi counter (avoid unlicensed touts). Grab is available and typically cheaper. Long-distance buses connect to Singapore and other Malaysian cities from both KLIA and KLIA2.

Equatorial rainforest climate, hot (28–34°C) and humid year-round with no true dry season. Rain can fall any month, though two monsoon seasons (Northeast: November–March; Southwest: May–September) bring heavier precipitation. Afternoon thunderstorms are frequent year-round and cause the most common flight delays.

Haze from Indonesian forest fires is a recurring issue August–October and occasionally reduces visibility enough to affect operations. Unlike typhoon zones farther north, KUL is not at direct tropical cyclone risk. Operations are generally consistent year-round.
