Q: Is Business Class: San Francisco → Singapore award space available right now?

Yes — AwardSecrets has recently verified Business award seats on this route. Space on this route is genuinely scarce — of everything we have recorded here, only a small fraction verified as bookable. Set an alert rather than searching repeatedly; when it opens it does not stay open long.

Q: What aircraft operates Business Class: San Francisco → Singapore?

Business Class: San Francisco → Singapore operates on the Boeing 787-9. One of the longest routes in commercial aviation. United flies San Francisco to Singapore nonstop, and United is the only carrier that has produced verifiable space for us here. Singapore Airlines flies the route too, but withholds its own award inventory from partner distribution almost entirely, so a search that turns up nothing on SQ is not evidence the flight is full.
