飞往旧金山国际机场 (SFO) 的旅客，如果提前做好计划，将会受益匪浅。从美国东海岸和中西部出发的国内航班，在1月至3月以及9月往往最具竞争力。从伦敦和法兰克福出发的跨大西洋航线，价格最低的时间段也大致相同。这座城市适合那些好奇心强、喜欢独立旅行，并渴望体验文化、美食和适宜步行的街区，而非海滩或主题公园的旅客。
运作良好的方面
- 标志性景色
- 世界级美食
- 强大的先买后付覆盖率
需要注意的事项
- 昂贵的城市
- 需要ESTA
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.
