SFO–SIN median is $367 — act fast when fares dip near $280

Key takeaways

• Median fare is $367, based on 30 daily snapshots of the cheapest available cached fares — a reliable baseline for budgeting.
• The bottom quartile sits at $360 or below (p25), meaning genuine deals are only marginally cheaper than the typical price most days.
• The 30-day low hit $280 — a 24% drop from the median — but the top 75% of days priced at $375 or less, so outlier deals are rare.
• Spread is 35% between the absolute low and high ($280–$377), suggesting occasional meaningful windows of cheaper fares do appear, but they don't last.
• No single dominant carrier was flagged in the data, so comparison-shopping across airlines on any given day remains worthwhile.

The full picture

The SFO–Singapore corridor is a long-haul premium route, yet the 30-day fare snapshot tells a story of surprising compression: 75% of observed daily prices landed between $360 and $375. That's an unusually tight band — a $15 spread across the interquartile range — which means if you're seeing anything in that zone, you're looking at a normal-market price, not a deal. The median of $367 is your realistic planning number.

The more interesting signal is at the extremes. The 30-day low of $280 represents a 24% discount to the median, and the high of $377 is only 3% above it. That asymmetry suggests that when prices do soften on this route, they move meaningfully downward rather than upward — so monitoring fares and acting quickly on any sub-$320 price is a sound strategy. Setting a fare alert at roughly 15% below the median ($310–$315) gives you a trigger that's ambitious but not unrealistic given the observed low.

Because no dominant carrier surfaced clearly in this data, it's worth checking aggregator results across all airlines operating the route — multiple carriers serve SFO–SIN via different hubs, and price drops often appear on one itinerary while others hold firm. One honest caveat: 30 snapshots capture a single narrow window of market behavior. Seasonal demand shifts — particularly around major holidays and school breaks in both the U.S. and Southeast Asia — can push prices well outside this observed range in either direction. Treat $367 as your anchor, not a guarantee.
