The full picture

The fare range for Seattle to Copenhagen — $258 to $347 — shows a 34% spread, which is meaningful but not extreme. Notably, the median ($258) matches both the low and the p25 figure, meaning most of the observed snapshots were priced at or near the cheapest end, with only a handful of higher-priced outliers pulling the average up. That's a reasonably encouraging sign for travelers: when fares on this route are cheap, they tend to stay cheap for multiple consecutive snapshots rather than fluctuating constantly.

With only 7 days of snapshots, however, this dataset is too thin to responsibly describe a booking-window trend — we can't say whether prices soften further out or closer to departure, since we simply haven't observed enough of the horizon. What we can say is that the $258–$347 band gives a realistic target: treat anything at or near $258 as a strong fare worth booking, and treat the $300+ range as the upper end of normal rather than a bargain.

No carrier data was distinguishable in this sample, so we can't speak to airline-specific pricing behavior or schedule patterns on this route. Day-of-week patterns are similarly not visible given the small sample size — any claim about specific weekdays being cheaper would not be supported by this data. The honest takeaway: this route shows a moderate, not dramatic, price spread, and the best move is to watch for fares at or below the $258 median rather than wait for a deeper dip that the data doesn't yet confirm exists. As more snapshots accumulate, a clearer booking-window pattern should emerge.
