San Francisco → Mumbai flights

Median $371 to Mumbai — bottom quartile fares dip to $331

Key takeaways

• $371 median fare over the 30-day sample gives a solid baseline for budgeting this route.
• Bottom quartile fares sit at $331, close to the observed $329 low — a realistic target if you're flexible.
• Top quartile climbs to $403, with an observed high of $476, so late or inflexible searches can cost meaningfully more.
• A 45% spread between low and high is wide, signaling real volatility rather than a tightly capped fare range.
• With 30 daily snapshots, this is a reasonably sized sample — enough to trust the median as a planning anchor.

The full picture

San Francisco to Mumbai fares show real variability over the 30-day tracking window, with prices ranging from a low of $329 to a high of $476 — a 45% spread that puts this route solidly in "volatile" territory rather than the tighter bands you'd see on shorter domestic routes. The median of $371 is a reasonable expectation for a typical search, but the gap between the 25th percentile ($331) and 75th percentile ($403) shows that a meaningful chunk of fares cluster in the low $330s to low $400s, with occasional spikes above that.

For long-haul international routes like this one, prices tend to soften when there's more booking runway — travelers searching well ahead of departure generally see more inventory near the lower end of the range, while last-minute searches skew toward the top of the spread or beyond it. Nothing in this data set pins down an exact number of weeks or days where softening reliably kicks in, so treat "book early" as a directional strategy rather than a precise rule tied to this data.

We don't have visibility into a dominant carrier or day-of-week patterns for this route in the current sample, so we can't respons­ibly claim that certain airlines or specific departure days are cheaper — doing so would be speculation dressed up as data. The most defensible takeaway is this: treat the $331–$403 range as your working target window, and be aware that the observed high of $476 is a real outcome, not an outlier to dismiss. The honest caveat here is that a 45% spread across 30 snapshots reflects meaningful day-to-day fluctuation, and 30 days — while a decent sample — is still a single month's snapshot of a route that likely has its own seasonal swings not fully captured here.
