Houston → Santiago flights
Median IAH–SCL fare is $373, but with only 9 snapshots and a 75% spread, book as soon as a low fare appears.
Houston–Santiago fares split hard: $373 or $654, little between
Key takeaways
- Median fare sits at $373, matching the observed low — a genuinely good price when you see it
- High end reaches $654, meaning fares can nearly double depending on the day
- 75% spread between low and high is wide — this route doesn't have a stable 'typical' price
- Bottom quartile (p25) equals the low of $373, suggesting cheap fares aren't rare outliers but do coexist with much pricier ones
- Only 9 snapshots collected — treat these patterns as a rough signal, not a firm forecast

The full picture
The data shows a route with a genuinely bimodal price pattern: a cluster of fares at $373 and another well above it near $654, with the 75th percentile already at the high end. That's a 75% spread from low to high — well outside the range where we'd call pricing 'stable.' When you check fares, you're likely to see one of two regimes rather than a smooth gradient in between.
With only 9 daily snapshots, we can't responsibly say when in the booking window prices typically soften — the sample is too thin to isolate a reliable early-bird or last-minute pattern for this specific route. What we can say is that the low end ($373) appeared often enough to set both the median and the p25, which suggests it's not a one-off fluke but a price point that recurs. If you see something close to $373, that's consistent with the best pricing we've observed, and waiting for a further drop isn't supported by this data.
We don't have visibility into a dominant carrier for this route from the data provided, so we can't speak to airline-specific patterns or whether the price split correlates with different airlines, routings, or connection times. Given the small sample and wide spread, our honest recommendation is tactical rather than strategic: monitor fares and be ready to book when you see pricing near the $373 median, since the alternative — paying near $654 — represents a substantial premium with no clear indication of when or why that occurs.
