Target $528–$546 for Dallas–Seoul: book early, watch for dips to $445

Key takeaways

  • The median fare is $546, with the bottom quartile sitting at or below $528 — a realistic target for patient bookers.
  • The floor of $445 appeared in our 30-day snapshot window, representing about an 18% discount versus the median.
  • The spread is 28% (from $445 to $570), meaning fare variance is meaningful — monitoring prices over time is worthwhile on this route.
  • Three-quarters of sampled fares came in at $569 or below, so paying more than $570 on this route would be above the historical ceiling in this data window.
  • With a high of just $570, this route shows a relatively compressed upper end — runaway last-minute spikes appear limited, though that can change with demand.

The full picture

Dallas–Seoul (DFW–ICN) fares in this 30-day snapshot window clustered tightly toward the upper end of their range: the median landed at $546, and the 75th percentile was only $23 higher at $569. That compression at the top suggests the route has a fairly firm ceiling under normal demand conditions — buyers who miss the best windows aren't necessarily punished with dramatic price spikes. The more interesting story is on the low end: a floor of $445 surfaced during the window, and the 25th percentile sits at $528, meaning roughly one in four snapshots came in below that number. That's the zone worth targeting.

On a long-haul transpacific route like this, fares generally respond to how far out you're searching. Deals toward the $445–$528 range are more likely to appear when booking is neither too last-minute (under three weeks out, when remaining inventory gets priced up) nor excessively far in advance (beyond six months, when carriers haven't yet introduced promotional fares). The practical sweet spot for most travelers on routes like DFW–ICN tends to be roughly six to ten weeks before departure, though this data doesn't directly measure booking-lead behavior — it reflects fare levels across a rolling 30-day window of cheapest available fares.

No dominant carrier was identifiable from this dataset, so route-specific airline strategies — like carrier-specific flash sales or loyalty-program pricing — aren't something we can speak to here. One honest caveat: 30 snapshots capture a slice of time, not a full seasonal cycle. Fares on this route can shift considerably around Korean holidays, U.S. school calendars, and peak summer travel. The $445 floor is real within this window, but it may not repeat in every travel season. Use this data as a benchmark, not a guarantee.
