Singapore Changi Airport (SIN) is a major international hub known for strong premium and full-service carrier presence alongside a good selection of low-cost airlines, so fares can range from budget-friendly to higher-end depending on carrier and season. Located about 20–25 km east of the city centre, travel options include the efficient MRT (about 30–35 minutes), taxis or ride-hailing (25–40 minutes, fares varying by time and service), and airport buses (40–60 minutes, typically the cheapest). Changi is praised for passenger comfort, amenities and quick transfers, while its size can mean longer walks between gates; overall it’s typically convenient but may be busier during peak travel periods.
San Francisco International (SFO) is the region’s primary international hub, serving full-service carriers like United, Delta, and major global airlines alongside some low-cost operators — fares can be competitive but often skew higher for transpacific and peak-time flights. The airport sits about 13 miles south of downtown San Francisco; BART connects directly in roughly 30–40 minutes with fares typically in the USD 10–12 range, while driving or taxis take 25–40 minutes depending on traffic and can cost from about USD 40–70. SFO is strong on amenities and international connections, though security lines and traffic to/from the city can add time; it’s a good choice for long-haul and connecting itineraries but can be pricier than nearby secondary airports.
