Mexico City to San Francisco (MEX–SFO) — Airlines, Schedules & Connections

Mexican passport holders need a B1/B2 visa to enter the United States. The visa is obtained through a US embassy or consulate and requires an in-person interview. B1/B2 visas are typically issued for 10 years with stays of up to 6 months per entry.

For land crossings within the border zone, a Border Crossing Card (BCC) is an alternative. The BCC costs USD 185 and is valid for 10 years. It allows entry up to 25 miles from the border in Texas and California, or 55 miles in New Mexico and Arizona. Travel by air or beyond the border zone requires a full B1/B2 visa with a valid passport.

Mexico City Metro Line B runs from Buenavista station to Pantitlán, then transfer to Line 5 to Terminal Aérea (Terminal 1); total about 45–60 minutes (MXN$7). Metrobús Line 4 connects Buenavista to the airport more directly (MXN$12, 30–40 min). Both are safe and reliable for travelers with minimal luggage.Authorized airport taxis (Taxi Ejecutivo or TICO) must be purchased inside the terminal; do not take street taxis. Rates to the Zona Rosa/Centro are MXN$200–300. Uber is permitted from city to airport. The airport is just 5km from the Zócalo but traffic can make the journey 30–60 minutes.

BART from SFO station (free AirTrain from any terminal to the station) to downtown San Francisco takes 30–40 minutes ($10.45 to Embarcadero). Traffic on 101 can make taxis and ride-hails much slower during peak hours; BART skips all of that. BART also reaches Oakland, Berkeley, and Millbrae for Caltrain connections.Ride-hails from SFO use a dedicated garage pickup area; follow signs. Taxis are metered; downtown SF costs $40–60. Caltrain to the Peninsula (Mountain View, Palo Alto, San Jose) requires taking BART to Millbrae station for the transfer. Rental cars are at a consolidated facility accessible by AirTrain.

Coastal fog dominates the climate pattern. The thick marine layer ("Karl the Fog") rolls into SFO from the Pacific regularly in summer (June–September), causing significant low-visibility delays even on days that appear sunny inland. Morning fog burns off by afternoon most days, but persistent IFR conditions can last all day. This is the primary flight disruption risk at SFO.

Temperatures are mild year-round (10–20°C) with little seasonal variation. Winters bring rain (December–March) and occasional atmospheric river events that cause brief but intense flooding on the 101. Summers are cool. Pack a light jacket year-round. Wind off the bay affects small aircraft approach paths.
