Dallas → Seoul flights

Target $546–$570 for Dallas–Seoul; patience can save $125+

Key takeaways

• Median fare is $570, based on 30 daily snapshots of the cheapest available cached fares on this route.
• Bottom-quartile fares sit at $546 or below — that's the realistic target for a genuinely good deal, not the statistical floor.
• The lowest recorded fare was $445, but the high hit $835 — an 88% spread signals this route is highly price-volatile.
• The middle 50% of fares fall between $546 and $700, meaning most shoppers land somewhere in that $154 band depending on when they search.
• Fares above $700 represent the top quartile — if you're seeing prices in that range, waiting or adjusting travel dates is likely worthwhile.

The full picture

Dallas–Seoul is a long-haul transpacific route, and the data reflects that volatility: an 88% spread between the lowest and highest observed fares ($445 vs. $835) is exceptionally wide, meaning the timing and flexibility of your search genuinely matter. The median of $570 is a reasonable anchor, but the p25 threshold of $546 tells you that roughly a quarter of daily fare snapshots came in below that — so $546 or under is an achievable, evidence-backed target rather than an optimistic outlier. Fares above $700 represent the upper quartile; if you're seeing those prices, the data suggests you're not in a favorable window.

On a route of this distance (roughly 14 hours nonstop), transpacific fares tend to soften when booked 6–10 weeks ahead of departure, before last-minute premium pricing takes hold and before the cheapest inventory sells out. The $445 floor in this dataset shows that deeply discounted fares do appear, but they are not the norm — count on them as an occasional opportunity rather than a planning baseline. A realistic goal is landing in the $500–$570 range, which the data shows is accessible without requiring a perfect-timing windfall.

The dataset does not surface a dominant carrier, so fare-shopping across all operators serving DFW–ICN — including one-stop routings through hubs like Tokyo, Beijing, or Taipei — is worth doing, as connecting itineraries frequently undercut nonstop pricing on this corridor. One honest caveat: 30 snapshots capture a moment in time, not a full seasonal cycle. Prices on transpacific routes can shift significantly around holidays, school breaks, and peak summer travel (June–August), so fares outside that sample window may behave differently than what this data implies.
