Flying from New York LaGuardia
New York LaGuardia is the smallest of New York's three airports and now the most modern after a complete 2017–2022 rebuild. The Q70 Limited bus runs free from each terminal to subway connections at Jackson Heights and Woodside; rail directly to LGA does not yet exist (the AirTrain proposal was canceled in 2023). Operations are domestic-only with limited transborder service. Delta, American and JetBlue have the largest schedules; Southwest and Spirit add ULCC capacity.
Arriving in San Francisco
San Francisco International sits 13 miles south of the city, with BART running directly from the international terminal station to Powell Street in 30 minutes for $10. Morning summer fog (May–August) routinely causes ground delays; book afternoon departures or mid-day arrivals during that window. Fares from US East Coast peak around tech-conference weeks (Apple WWDC in June, Salesforce Dreamforce in September) and are cheapest in February.
