About This Route

43 business award seats seen here in the last 7 days (last verified 1hr ago). 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.

💡 Insider Tip

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.
