SFO–Singapore fares hover near $280 — bottom quartile tops out at $276

Key takeaways

• Median fare across 30 days of snapshots is $280, with a range of $268–$343
• Bottom quartile (p25) sits at $276, just below the median — the cheap end of the market isn't dramatically far from typical pricing
• Top quartile (p75) jumps to $330, showing the upper range is where most of the spread lives
• Overall spread is 28%, moderate rather than extreme — timing matters, but mispricing is survivable
• Sample is a full 30-day window, enough to trust the median as a reasonable benchmark

The full picture

Over the 30 days we tracked, SFO–Singapore fares ranged from $268 to $343, with a median of $280. That's a 28% spread between low and high — enough to make timing worthwhile, but not so wide that this is a wildly volatile route. Notably, the bottom quartile ($276) sits close to the median ($280), meaning a large share of observed fares cluster near the low end. The real separation shows up above the median: the top quartile climbs to $330, so the upper half of the distribution is doing most of the spreading.

We don't have booking-date-to-departure-date lag in this dataset, so we can't say precisely when in the booking horizon this route tends to soften. What the snapshots do show is that fares near $270–$280 appeared often enough to anchor the median there, while the $330+ fares look more like outliers or peak-period pricing rather than the norm. A practical takeaway: if you're quoted something in the high $320s or above, you're in top-quartile territory and have reasonable grounds to wait or keep checking, since cheaper fares were available roughly a quarter of the time.

No single carrier or day-of-week pattern is visible in this data, so we can't make claims about specific airlines or weekday effects on this route — and we'd caution against the common advice that a particular day of the week is reliably cheaper to book, since that isn't something this dataset can confirm. The honest summary: aim for the $270–$280 range as a realistic target, treat anything under $276 as a good fare worth booking, and view $330+ as a signal to wait if your travel dates are flexible. Keep in mind this reflects 30 days of cached fare snapshots, not a full seasonal cycle, so longer-term trends (holiday surges, fare sales) aren't captured here.
