Los Angeles → Seoul flights

Target $362–$389 for LAX–Seoul — spread is wide enough to matter

Key takeaways

• Median fare is $389 across 30 daily snapshots — a solid anchor for budget planning.
• Bottom-quartile fares sit at $362 or below — achievable, but not the norm; expect to monitor for a window.
• The top quartile starts at $460, meaning roughly one-in-four snapshots showed fares 18% above median — timing matters.
• A 37% spread ($359–$493) is wide enough that passive monitoring and a flexible booking date can translate to real savings.
• The $359 floor is rare — treat it as a ceiling for your target rather than an expectation.

The full picture

The 30-day snapshot range for Los Angeles to Seoul Incheon runs from $359 at its lowest to $493 at its highest — a $134 spread that represents roughly 37% of the low-end fare. That kind of spread is meaningful. It tells us this route has genuine pricing volatility, not just trivial fluctuations around a fixed price point. The interquartile range — $362 to $460 — is the most actionable zone: half of all observed fares landed in this $98 window, which means a patient, alert shopper has a realistic shot at the lower end without waiting for a rare outlier.

On a transpacific route of this length (roughly 11–12 hours), fares typically respond to how far out you're booking, how full the cabin is running, and seasonal demand cycles around holidays in both the US and South Korea. While this dataset doesn't tag specific departure dates, the presence of fares near the $359–$362 floor within a 30-day window suggests that softer pricing does surface periodically — likely tied to midweek departures or shoulder periods between peak travel seasons. If your travel dates are flexible, checking fares across a two-to-three week departure window rather than a single date will increase your odds of landing near that p25 threshold of $362.

Carrier data isn't broken out in this snapshot, but LAX–ICN is served by Korean Air, Asiana, and several alliance partners including Delta and United codeshares. Pricing competition on this corridor is real, which helps explain why the floor gets as low as $359. That said, the $493 high in the dataset is a reminder that waiting too long — or searching around high-demand periods — can push costs well above the median. One honest caveat: 30 daily snapshots reflect cached lowest fares at the moment of capture and may not represent what you'll see at checkout on any given day, particularly if availability at the lowest fare bucket has already closed.
