Barcelona is served primarily by Barcelona–El Prat (BCN), the city’s international hub handling most long-haul and European flights, and by a smaller low-cost airport for occasional charters and budget services. El Prat is typically used by full-service carriers as well as low-cost airlines operating dedicated terminals, so fares can range from premium to budget depending on carrier and season. The airport lies about 12 km southwest of Plaça de Catalunya; metro and train links reach central Barcelona in roughly 25–35 minutes (fares usually in the low single-digit euros), while taxis take around 20–30 minutes with fares commonly higher. Pros: well-connected, multiple terminal amenities; cons: can be busy during peak periods and transfers between terminals may add time.

San Francisco International Airport (SFO) is the region’s primary international gateway and a major West Coast hub, handling a mix of full-service carriers (including legacy and international airlines) alongside some low-cost operators. It sits about 13 miles south of downtown San Francisco; plan for roughly 20–45 minutes by car depending on traffic, with ride-shares and taxis typically costing more than public transit. BART connects the airport to downtown in around 30–40 minutes for a moderate fare, while airport shuttles and private transfers can be more convenient for groups. Pros: extensive international connections, amenities, and frequent flights. Cons: can be busy, occasional delays, and ground transport times vary with traffic.
