How do I get from Singapore to San Francisco?

Response:
There are several direct flights from Singapore to San Francisco. Singapore Airlines and United Airlines offer several daily direct flights which take about 17h each way. Alternatively, you could take a connecting flight in Japan which would take about 20h. Driving wouldn't work because there's no continuous land route from Singapore to San Francisco. You could take a ship, but you'd need to find one that sails this route in addition to taking 2 weeks for the journey.
