The airport sits about 13 miles (21 km) south of downtown San Francisco; the BART rapid transit connects terminals to downtown in roughly 30–40 minutes with fares typically in the mid-single-digit dollars, while taxis or app rides take about 25–45 minutes depending on traffic and usually cost substantially more.

Fly nonstop from San Francisco to Phoenix for the fastest, most convenient way to get between these two Sun Belt cities — fewer hassles, no layovers, and more time to enjoy your trip. While connecting options can occasionally be cheaper, a direct flight saves valuable time and offers a more comfortable, predictable travel experience, making it a smart choice for both short breaks and business trips.

Phoenix Sky Harbor International (PHX) is the region’s primary international and domestic gateway, serving legacy carriers and many low-cost airlines alike; it can be convenient for connecting long-haul flights or affordable point-to-point travel. The airport sits about 4–5 miles east of downtown Phoenix, with light rail or airport shuttles taking roughly 20–30 minutes and local buses or rideshares often costing in the low double digits. While Sky Harbor offers full-service lounges, numerous dining options, and frequent flights, it can be busy during peak hours and security lines may be longer. For quieter, budget-oriented alternatives, nearby Phoenix-Mesa Gateway (AZA) lies farther southeast and is typically used by discount carriers.
