Best Time to Book

Newark → Seoul flights

EWR–Seoul fares show a $396 median over 12 snapshots; book when you see fares near the low $300s and avoid waiting past $426.

Median fare $396 — but a thin sample means don't read too much into it

Key takeaways

Median fare of $396 across the sampled window, a reasonable anchor for budgeting
Low end hit $286, suggesting occasional dips worth jumping on
Bottom quartile sits at $396, meaning most observed fares cluster at or above the median
Top quartile reaches $426, so the upper range isn't dramatically higher than typical
Spread of 49% between low and high — notable swings, but only 12 samples, so treat this as a rough signal, not a firm pattern

The full picture

The EWR–Seoul route shows a median fare of $396 across 12 daily snapshots, with prices ranging from a low of $286 to a high of $426. That's a 49% spread, which is substantial — but with only 12 samples, this is a thin dataset, and a single unusual fare on either end could be skewing the range. Treat the $396 median as a reasonable planning number rather than a precise target.

What's more interesting is the quartile data: both the 25th and 75th percentiles sit close to the median and high end ($396 and $426 respectively), meaning most of the observed fares were clustered in the upper half of the range rather than spread evenly. That implies the $286 low was more of an outlier than a representative data point. If you're booking this route, it's more realistic to expect fares in the high $300s to low $400s than to count on repeating that low.

We don't have enough data here to identify a reliable day-of-week pattern or carrier-specific behavior — the sample size is simply too small, and no dominant carrier was distinguishable in the data provided. The practical takeaway: budget around $396–$426 for this route, and treat any fare near or below $300 as a genuine deal worth booking quickly rather than something to wait for or expect. The honest caveat is that 12 snapshots is a small sample for a long-haul international route like this, so confidence in these figures is moderate — this is a directional guide, not a guarantee.
