The full picture

The data shows a notably narrow pricing band for Boston to Miami: fares ranged from $79 to $92 across 12 days of snapshots, with a median of $87. A 16% spread is on the low end of what we typically see for domestic leisure routes, meaning there isn't a large reward for trying to time your purchase perfectly — the difference between a lucky day and an unlucky one is roughly $13.

Because the spread is tight and clustered (the 25th percentile is already $87, equal to the median), this route doesn't show the kind of dramatic early-bird-versus-last-minute swings you'd see on more volatile itineraries. That said, with only 12 days of observations, we can't confidently say where in a longer booking horizon — weeks versus months out — prices might soften further. The data simply doesn't extend far enough to map that curve reliably.

We also don't have enough carrier-level detail in this dataset to identify a dominant airline or day-of-week pricing pattern for this route, so we won't speculate on either. The honest takeaway: if you see a fare at or below the $87 median, it's a reasonable price by recent historical standards, and holding out for a dramatically better deal may not pay off given how compressed this range is. Our main caveat is sample size — 12 snapshots is a useful snapshot of recent conditions but too thin to serve as a long-term seasonal guide, so treat these numbers as a current read rather than a permanent rule for this route.
