The full picture

Fares between Dallas and Seoul have ranged from $478 to $611 over the past 26 days, with a median of $531. That $133 spread (28%) tells us this route isn't flat-priced — there's real room to save if you catch fares in the lower quartile, which sits around $499. Roughly a quarter of observed fares fell at or below that mark, so treat $499-$531 as a realistic target range rather than a rare fluke.

With 26 days of snapshots, we're looking at a meaningful but not exhaustive sample — enough to establish a credible median and spread, but not enough to confidently map out seasonal booking-window behavior (like how prices trend 3 months out versus 3 weeks out). What we can say is that the data shows consistent clustering around the median, with the $604-$611 fares appearing as the exception rather than the norm. That's useful: it means chasing a fare meaningfully below $531 is a reasonable goal, not wishful thinking.

We don't have reliable visibility into day-of-week patterns or a dominant carrier for this route in the current dataset, so we won't speculate on whether Tuesday departures or a specific airline's pricing quirks are driving the spread — that would be guessing beyond what the numbers show. The honest takeaway: this is a moderately variable route where patience and flexibility around the $499-$531 range should pay off, but the 26-day sample is a snapshot, not a full seasonal picture, so treat these figures as a current baseline rather than a permanent rule.
