飛往舊金山國際機場 (SFO) 的旅客，如果提前做好計劃，將會受益匪淺。從美國東岸和中西部出發的國內航班，在1月至3月以及9月往往最具競爭力。從倫敦和法蘭克福出發的跨大西洋航線，價格最低的時間也大致相同。這座城市適合那些好奇心強、喜歡獨立旅行，並渴望體驗文化、美食和適合步行的街區，而非海灘或主題樂園的旅客。

需要注意的事項
- 昂貴的城市

Forty-plus airlines fly into SFO, so there's no shortage of ways in, but nothing about the arrival is cheap: expect a cost-of-living index above 97 and mid-range daily costs of USD 146 once you land. The ESTA takes 72 hours to clear, so sort that before you even think about fares. What you're paying for is real: the Golden Gate Bridge, Alcatraz, the Mission's murals, sourdough at Boudin, cioppino at the Wharf. Affirm, Afterpay, Klarna and Zip are all sitting at checkout if you'd rather spread that cost than feel it all at once.
