The full picture

The data shows a median fare of $490 for Boston to Seoul, with prices ranging from $490 to $601 across the observed snapshots. A 23% spread between the low and high end is moderate — not razor-tight, but not wildly volatile either. Notably, the 25th percentile matches the median exactly at $490, suggesting that a meaningful share of observed fares cluster at or near this floor, while a smaller set of pricier fares pull the top quartile up toward $601.

We can't respond with confidence about when in the booking horizon prices soften, because this dataset covers only 7 days of snapshots — far short of the 30-day window needed to spot a reliable trend. What we can say is that fares at or below $490 appear to represent the lower end of what's been observed recently, so if you spot that price, it's a reasonable target rather than a fluke. Anything creeping toward $600 is on the expensive side relative to this sample.

There's no visible day-of-week or carrier pattern in this data — the sample is too small to isolate those effects, and no dominant carrier was identifiable. The honest caveat here is significant: with only 7 data points, this snapshot gives a rough sense of the current price band for this route, but it shouldn't be treated as a statistically robust forecast. Treat $490 as a useful benchmark for comparison shopping, not a guaranteed low, and revisit this route's pricing data as more snapshots accumulate before making a high-stakes booking decision based on timing alone.
