The full picture

The data shows a $428–$538 range for Miami to Seoul fares, a 26% spread that suggests real price movement rather than a flat market. With the median at $483, roughly half the observed fares fell below that mark, and the bottom quartile (p25) at $478 gives a concrete target for travelers comparing offers — anything meaningfully under $480 looks like a good deal based on this window, while fares creeping toward $538 sit at the expensive end of what we've seen.

We only have 12 days of snapshots here, which is a thin sample for drawing firm conclusions about booking-horizon timing. We can't responsibly say fares reliably soften at a specific point before departure, or that one weekday beats another for booking, because the data doesn't give us enough repeated observations to separate signal from noise. What we can say is that the spread itself — nearly $110 between cheapest and priciest fares — means it's worth checking prices more than once before committing, since the gap between a median fare and a high-end fare is substantial enough to matter on a long-haul route like this.

The honest takeaway: use $478–$483 as your benchmark range, and treat anything near or below $478 as a strong fare worth booking. But with only 12 samples, this snapshot reflects a narrow slice of time rather than a full seasonal pattern, so fares could shift outside this range as more data comes in. Travelers with flexibility should keep watching rather than assuming the window we've captured is representative of the route year-round.
