Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the international hub handling most long-haul and full-service carriers; it’s about 30–35 km east of the city centre, typically a 30–60 minute drive depending on traffic. Ground links include the Airport Rail Link to central Bangkok (around 25–30 minutes, moderate fares), taxis (variable time and fare), and airport buses. Don Mueang (DMK) is the older, northern airport popular with low-cost and regional airlines; it sits roughly 20–25 km from central areas and can be a 30–60 minute trip by taxi or bus. Pros: Suvarnabhumi usually offers more international connections and modern facilities, while Don Mueang can be cheaper and quicker for budget carriers. Cons: both can face heavy traffic to the city and peak-hour congestion; budget travellers should factor in transfers between the two airports when planning tight connections.

San Francisco International Airport (SFO) is the Bay Area’s primary international gateway, handling a mix of full-service global carriers and several domestic and low-cost airlines. Located about 20 miles (32 km) south of downtown San Francisco, it’s typically a 25–45 minute drive without heavy traffic; BART trains connect the airport to the city center in roughly 30–40 minutes with fares usually in the mid single digits, while airport shuttles and taxis/rideshares can be pricier depending on surge and luggage. SFO offers extensive lounges and services suited to long-haul travel, but its size can mean longer walks and security lines; overall it’s convenient for international and connecting passengers, less ideal for those seeking a tiny, quick regional airport.

The minimum one-way ticket price from Bangkok to San Francisco is $335 (November 2025), while the maximum is $521 (January 2026). On average, a ticket costs $445–$955.
