Atlanta → Seoul flights

Fares cluster at $563 — but a thin sample means surprises possible

Key takeaways

• $563 median fare, and it also marks both the low and the 25th percentile — meaning the bottom quartile of fares is bunched right at the floor
• $852 high shows a real ceiling exists, pushing the overall spread to 51%
• 75th percentile at $826 suggests once prices move off the floor, they jump quickly rather than climbing gradually
• Only 11 snapshots were sampled, too thin to confidently characterize weekday or booking-window patterns
• No single carrier dominance was visible in the data, so we can't attribute the price jumps to a specific airline's pricing behavior

The full picture

The data shows a route with a wide 51% spread between low and high fares, but the distribution itself is revealing: the median ($563) equals both the low and the 25th percentile, meaning most observed fares were clustered right at the cheapest point. The jump to $826 at the 75th percentile and $852 at the high end suggests a smaller number of snapshots caught a distinctly pricier fare class or itinerary — rather than a smooth, gradual increase in cost.

With only 11 days of snapshots, we don't have enough coverage to responsibly generalize about where in a typical booking horizon prices soften. What we can say is that the bulk of the observed fares sat near $563, so travelers monitoring this route have a reasonable shot at landing close to that figure if they catch pricing before it shifts into the upper quartile. We can't point to a specific day-of-week or booking-window pattern because the sample size doesn't support that level of granularity, and no dominant carrier emerged clearly from the data to explain the jump between quartiles.

The honest takeaway: this route shows a real split between a cluster of cheaper fares and a smaller set of notably higher ones, but with just 11 data points, we'd caution against reading too much into timing strategies. Treat $563 as a realistic target based on what's been observed, but be prepared for the possibility of landing in the $800+ range if availability at the lower price point has dried up by the time you search. More consistent daily tracking over a longer window would sharpen this picture considerably.
