New York → Seoul flights

Target $415 on JFK–Seoul — flexibility can save ~$90

Key takeaways

• Median fare is $415, based on 30 daily snapshots of the cheapest cached fares on this route.
• Bottom-quartile fares fall at or below $412 (p25), suggesting the low end is achievable but not the norm.
• The floor was $327 — roughly $88 below median — indicating genuine deals surface periodically on JFK–ICN.
• Spread of 46% between low ($327) and high ($476) is wide enough that timing your search meaningfully affects what you pay.
• Top-quartile fares reach $450+ (p75), so waiting too long raises real risk of paying well above median.

The full picture

JFK to Seoul (Incheon) is a long-haul transpacific route where fares in our 30-day snapshot window ranged from $327 to $476 — a spread of 46%. That's a meaningful gap. The interquartile range, however, is tighter: half of all observed cheapest fares fell between $412 and $450. What this tells you is that most days the market clusters in a relatively narrow band just above $400, but genuine dips do materialize — and when they do, they can be substantial.

The $327 low and the $412 p25 threshold suggest that roughly one in four snapshots captured fares in or below the low $400s. On a route of this distance and price point, that's a credible saving of 10–20% versus the typical going rate. The practical implication: if you have flexibility in your travel dates and can monitor fares over a few weeks rather than booking on impulse, there's a reasonable chance of landing below the $415 median. Booking too far out (six-plus months) or too close in (under three weeks) on transpacific routes historically correlates with elevated fares, though our data doesn't directly measure booking lead time — so treat that as general industry context, not a data-derived claim.

No dominant carrier was identifiable from this dataset, so we can't point to a specific airline as the consistent price leader on JFK–ICN. Multiple carriers operate this corridor, and competition among them likely contributes to the fare volatility seen here. One honest caveat: 30 snapshots reflect a single rolling window and may not capture seasonal demand swings — peak summer and holiday travel around Lunar New Year or Chuseok can push fares well above the ranges observed here. Treat the $415 median as a useful benchmark for normal-demand periods, not a year-round guarantee.
