The full picture

The fare data for Miami to SAN shows a relatively narrow band: a median of $151, a low of $140, and a high of $167. With a spread of just 19%, this isn't a route where travelers are likely to find dramatic bargains by waiting — nor are they likely to get badly burned by booking early. The bottom quartile ($140) and top quartile ($167) are close enough together that most fares cluster near the median, suggesting pricing on this route is fairly stable day to day.

Because the sample only covers 12 snapshots, we can't make strong claims about a specific booking window that reliably softens prices — the dataset simply isn't large enough to isolate a seasonal or advance-purchase pattern with confidence. What we can say is that if you see a fare at or below the $140–151 range, you're already in the lower quartile of observed prices for this route, which is a reasonable signal to book rather than wait.

No single carrier stood out clearly in the data, so we can't speak to airline-specific pricing behavior or whether certain days of the week consistently favor one carrier's fares. The honest caveat here: with only 12 days of snapshots and a modest 19% spread, this route doesn't give us enough signal to recommend precise timing strategies. Treat the $140–$167 range as a realistic planning band, and prioritize booking when your travel dates are confirmed rather than chasing marginal savings that the data doesn't clearly support.
