New York → Seoul flights

JFK–Seoul: median $439, but fares swing from $300 to $533

Key takeaways

• Median fare sits at $439, with the bottom quartile (25th percentile) at $417 or below
• Low of $300 and high of $533 across 30 daily snapshots — a wide range for this route
• 78% spread between low and high signals real volatility, not just noise — flexible travelers have room to find outsized savings
• If you see a fare near or below $417, that's bottom-quartile territory worth booking
• Fares above $456 (75th percentile) are on the expensive side relative to the last 30 days

The full picture

Over 30 days of tracking, JFK–Seoul fares have ranged from a low of $300 to a high of $533, with a median of $439. That 78% spread is substantial — this isn't a route where prices hover tightly around one number, so treat the median as a benchmark rather than an expectation. The bottom quartile (25th percentile, $417) and top quartile (75th percentile, $456) show that the middle half of observed fares actually cluster in a fairly narrow $39 band, even though the outer extremes stretch much further in both directions.

That gap between the quartile range and the full low-high spread tells a specific story: most days see fares in the $417–$456 zone, but occasional dips to $300 and spikes to $533 pull the overall range wide. Practically, this means a fare quoted near or under $417 is a genuinely good find worth acting on, while anything above $456 is on the pricier end of what we've observed. We don't have enough visibility into the booking calendar itself — this data reflects snapshots of cached fares over 30 days, not how far in advance each ticket was purchased — so we can't say definitively whether booking 2 weeks or 2 months out performs better. What the data does support is relative positioning: know where a quoted price falls against the $417/$439/$456 markers before deciding.

We don't have carrier-level detail in this dataset, so no airline-specific patterns can be claimed here. The honest takeaway: this is a long-haul international route with meaningful day-to-day price variability (78% spread), and the sample of 30 days is a reasonable but not exhaustive window — a longer history would sharpen confidence in how often true outliers like $300 actually appear.
