Cheap Flights from Ulaanbaatar to San Francisco Starting at $527

San Francisco International (SFO) functions as the region’s primary international hub, handling long-haul carriers alongside major U.S. airlines and several full-service international partners; low-cost carriers also operate but may be more common at nearby secondary airports. Located roughly 13 miles south of downtown San Francisco, SFO is typically reachable in 20–40 minutes by car depending on traffic; BART trains connect the airport to the city center in about 30–40 minutes with fares usually in the low-to-mid single digits, while airport shuttles and taxis can be pricier. Pros include wide service options and robust ground transport; cons can be crowding during peak periods and variable security/wait times.

Chinggis Khaan International Airport (UBN) is Mongolia’s main international gateway and typically functions as the country’s premium hub for long-haul and regional services.

The airport lies about 50–60 km southeast of Ulaanbaatar’s center, with transfer options including airport shuttle buses (roughly 1–1.5 hours), private taxis (around 45–75 minutes) and prebooked transfers; expect taxi fares to be notably higher than local bus prices.
