The full picture

The data shows a median fare of $372 for Boston to Copenhagen, with a wide observed range between $319 and $489 — a 53% spread. That's a meaningful gap, but it's worth noting that the p25 and p75 values are both $372, which tells us the bulk of the sampled fares actually clustered close to that median. The $489 high and $319 low appear to be outliers rather than the norm, so travelers shouldn't necessarily expect fares to swing wildly on any given search.

With only 10 snapshots in this dataset, we can't confidently map out a booking-window curve — that is, we can't say with precision whether fares soften three weeks out versus three months out. What we can say is that the tight clustering around $372 suggests this route has a fairly stable baseline price, and the real opportunity is catching one of the occasional dips toward $319 rather than trying to time a broader seasonal trend. Booking when you see a fare at or below the median is a reasonable, data-supported move.

We 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 caveat here is the sample size: 10 days of snapshots is a useful starting signal, but it's thin enough that a longer observation window could shift the median or reveal patterns — like weekday softening or seasonal effects — that simply aren't visible yet. Treat $372 as a solid reference point for a fair price, and consider $319 a strong deal if you see it again.
