San Francisco International Airport (SFO) is the region’s primary international gateway and a major hub for full-service carriers as well as several international airlines; low-cost carriers also operate here but the airport tends to host more premium transcontinental and long-haul services. Located about 21 km (13 miles) south of downtown San Francisco, travel typically takes 20–40 minutes by BART or car depending on traffic; BART fares run roughly $10–$12 while airport shuttles and taxis vary more. Ground transport options include BART, airport shuttles, taxis, rideshares and rental cars. Pros: extensive international connections, full passenger amenities and frequent transit links. Cons: security lines and peak-hour traffic can add time and cost.

Mexico City is served mainly by Benito Juárez International (MEX), the country’s primary international hub that handles most full-service carriers and some low-cost airlines, plus the newer Felipe Ángeles International (NLU) to the north which is positioned to relieve capacity and attract budget and domestic services. MEX sits about 6–8 km east of downtown and is reachable by metro, Metrobus and taxis—typical journeys take 20–45 minutes depending on traffic, with public transit fares usually low while airport taxis or rideshares can be noticeably more expensive. NLU is roughly 45–55 km from the center; transfers often take 45–90 minutes by shuttle, private transfer or long taxi rides, so travelers trade longer road time for potentially lower fares and fewer crowds. Pros: MEX offers excellent connectivity and frequent international services; NLU can be quieter and cheaper. Cons: MEX can be busy and congested, and NLU’s greater distance adds travel time and extra transfer planning.
