San Francisco International (SFO) is the region’s main international hub, handling long-haul, transpacific and many domestic flights and serving legacy carriers and several full-service foreign airlines; low-cost carriers also operate here. Located about 21 km (13 miles) south of downtown, the airport is typically 20–30 minutes by BART or 25–45 minutes by car depending on traffic; BART fares are usually in the low-to-mid single digits while rideshares or taxis can be notably more. SFO is often seen as more premium and better equipped than smaller Bay Area fields, with plentiful lounges and connections, though peak-hour lines and airport congestion can reduce convenience.
Seattle is served primarily by Seattle–Tacoma International Airport (Sea–Tac), a major Pacific Northwest hub that handles most international and transcontinental flights and typically hosts full-service carriers like Alaska Airlines, Delta, and international airlines; fares can range from budget-competitive to premium depending on carrier and season. Sea–Tac sits about 14 miles (roughly 20–35 minutes by car) south of downtown Seattle and is connected by the Link Light Rail with journey times around 35–40 minutes for fares typically under $4.50; taxis and rideshares usually take 25–40 minutes and cost more. Pros: extensive route network and modern passenger facilities; cons: can be busy during peak hours and parking/taxi queues may add time.
