Over the last 30 days, every day in the window had a cached fare, giving a full picture of how Seattle–Singapore pricing moves. The median sits at $278, just above the $271 floor, which tells us the cheapest fares aren't rare outliers — they represent a realistic target for a good chunk of the window. But the top quarter of fares climbed to $347 and beyond, up to a high of $363, so the distribution has a meaningful upper tail.
That 34% spread between low and high is wide enough to take seriously. With p25 at $272 — barely above the floor — and p75 at $347, the middle half of fares spans nearly $75, which means a lot of the variation isn't noise; it reflects real swings in availability or demand across the window. The practical takeaway is that fares near $278 or below represent good value, while anything pushing past $320-330 is drifting into the expensive half of what's been observed.
We don't have carrier-level detail in this dataset, so we can't say whether one airline is consistently cheaper or whether specific days of the week trend lower — those patterns may exist, but they're not visible here. The honest caveat: with a spread this size, the median is a useful anchor, but booking on a single data point is risky. Treat $278-290 as a reasonable target range, and be ready to act if you see something close to the $271 floor, since the data suggests the top quarter of fares runs meaningfully higher.
Why we regenerated this article: Median fare ↓ 20% ($347 → $278). We only rewrite when the underlying price index actually moves — stable weeks keep the previous take.
