$649 rt SFO to Singapore

United Airlines

10 Deal Rating

This gateway to southeast Asia offers a dynamic mix of cultures, ideas, histories and architecture. The small island country is known for its eclectic street fare that delivers an elegant fusion of flavors, a contrasting juxtaposition of old religious temples and modern skyscrapers, its tropical climate complementing lush rainforests, and much, much more.

Heads Up

Not many airlines offer direct flights to Singapore from the Bay, but United is doing so at the cost of one-stop fares.
