New York → Seoul flights

Fares cluster near $450–456 — the median $456 is a fair target

Key takeaways

• Median fare of $456 anchors this route across the 30-day sample.
• Middle 50% of fares sat between $450 and $456, a notably tight band despite the wider overall spread.
• Low of $416 appeared as an outlier rather than the norm — don't bank on repeating it.
• High of $505 shows some snapshots ran well above median, likely on higher-demand search days.
• 21% spread between low and high is moderate — worth comparing a few dates, but don't expect dramatic swings.

The full picture

Over the 30-day window tracked for JFK–Seoul, fares showed a $456 median with a fairly narrow interquartile range — the 25th to 75th percentile spanned just $450 to $456. That tight clustering tells us most days priced within a few dollars of typical, which makes $456 a reasonably reliable planning number rather than a rough guess.

The wider low-high range ($416 to $505, a 21% spread) shows some volatility exists, but it's driven by a smaller number of outlier snapshots rather than routine day-to-day swings. Given the tight p25–p75 band, chasing a specific booking window for savings is less useful here than it would be on a route with a wider quartile spread — the data doesn't show clear evidence of a soft period versus a spike period within these 30 days, just occasional higher-priced snapshots pulling the ceiling up.

No dominant carrier was identifiable in this data, so we can't speak to airline-specific pricing patterns or whether one carrier is driving the low or high end. Practically, this means booking whenever you find something at or below the $456 median is a solid move, and treating anything near $505 as a signal to wait or check alternate dates. The honest caveat: 30 days of snapshots is a decent sample size, but it doesn't capture full seasonal booking-curve behavior (e.g., how prices move 2-3 months out versus 2-3 weeks out), so this reflects a snapshot-in-time pattern rather than a full seasonal forecast.
