Best Time to Book

Seattle → Cancun flights

Seattle–Cancún fares have a median of $200 over a thin 9-day sample; most quotes bunch at the low end, with occasional jumps.

Most fares cluster at $200 — a handful of spikes to $368

Key takeaways

Median fare is $200, and both the 25th and 75th percentiles sit at the same $200 — most snapshots landed right at that price.
High of $368 shows occasional spikes well above typical pricing, driving an 84% spread between low and high.
Low of $200 matches the median, suggesting $200 is the common baseline fare rather than a rare deal.
Only 9 daily snapshots were sampled, so this is a thin dataset — treat patterns as directional, not definitive.
No dominant carrier was identifiable from the data, so airline-specific booking patterns can't be confirmed.

The full picture

The data shows a tight cluster of fares at $200 — both the 25th and 75th percentile match the median exactly, which means on most days checked, this route priced right around that level. The $368 high is an outlier rather than the norm, but it's responsible for an 84% spread between the cheapest and priciest fare observed, so travelers should be aware that occasional spikes do happen even when the baseline is stable.

With only 9 snapshots in this sample, we can't reliably map out a booking horizon curve — there isn't enough data to say whether fares soften further out or closer to departure. What we can say is that $200 appears to be a realistic target based on how consistently it showed up across the sample, and that seeing a quote near $350+ likely means checking back or trying different dates rather than assuming that's the going rate.

No single carrier stood out clearly in the data, so we can't speak to airline-specific pricing behavior on this route. The honest caveat here is the sample size: 9 days is a small window, and a fare distribution this tightly bunched with one high outlier could shift meaningfully with more data. Treat $200 as a solid reference point, but verify closer to your actual travel dates rather than treating this as a guarantee.
