The full picture

The data shows a $120–$476 range for BOS–Cancún fares, with a median of $183 — well below the midpoint of that range. That gap tells you the distribution is skewed: most snapshots cluster toward the lower end, while a smaller number of high-priced fares (likely last-minute or peak-demand searches) pull the average and high mark upward. The 297% spread confirms this is a route where timing matters more than usual; it's not a market with stable, narrow pricing.

With only 12 snapshots, we can't responsibly point to specific weeks or a precise booking window that reliably softens prices. What we can say is that the bottom quartile — fares at or below $157 — appears often enough in the sample to be a realistic target rather than a fluke. If you're seeing quotes above $300–400, that's consistent with the upper tail we observed, and waiting or adjusting dates may bring you back toward the median or lower.

We don't have enough carrier-level detail in this dataset to credibly call out a dominant airline or day-of-week effect for this route, so we're not going to invent one. The honest takeaway: anchor your expectations around the $183 median, treat anything near $157 as a good deal worth booking, and be skeptical of paying north of $300 unless your dates are fixed and inflexible. Given the thin sample size (12 days), we'd caution against over-reading short-term dips or spikes — this is a directional read on pricing behavior, not a definitive seasonal forecast.
