Fly from San Francisco to Singapore $497 roundtrip on United Airlines from this fall or winter, nonstop on the return leg.
This fare is widely available for travel on Mondays, Tuesdays, Wednesdays, and Thursdays, from September through mid-December.
As an example, I found this price available departing San Francisco SFO on Monday, November 11, returning from Singapore SIN on Thursday, November 21, 2019.
Please take note that there is a long layover on the outbound flight stopping in Hong Kong (HKG), the return leg from Singapore to San Francisco is nonstop.
This price includes a carry-on bag, a personal item, and two free checked bags.
Standard advanced seat selection is included.
To fly nonstop on both portions of the itinerary, the price will jump up to $655 roundtrip on United, which is still below the going rate offered by Singapore Airlines.
