Dallas → Seoul flights

Target $462–$473 on DFW–Seoul — the window is narrow

Key takeaways

• Median fare is $473 across 30 daily snapshots — a reliable anchor for budgeting this route.
• Bottom quartile (p25) is $462, meaning roughly one in four sampled fares came in at or below that figure — a realistic stretch target.
• The high reached $547, about 16% above median, suggesting meaningful upside risk if you wait too long.
• Price spread is 20% from low to high — moderate, not dramatic, so dramatic last-minute deals are unlikely on this corridor.
• The $454 floor is real but thin — fares that low appear infrequently, so treat $462–$473 as the practical target range.

The full picture

Dallas–Seoul (DFW–ICN) is a long-haul transpacific route where fares behave with more predictability than short-haul markets — and this dataset bears that out. Over 30 daily snapshots, the cheapest available fares ranged from $454 to $547, with a median of $473. The interquartile range of $462–$501 is relatively tight, telling you that this route doesn't swing wildly day to day. That's useful: it means you're not chasing a moving target so much as waiting for the fare to dip into the lower quartile rather than drift toward $500-plus.

The 20% spread — low to high — is moderate by transpacific standards. It's enough to matter (a $93 swing on a round trip adds up), but it's not the kind of volatile route where holding out for weeks might yield a dramatically different price. The practical implication is that the biggest risk isn't missing a flash sale; it's letting fares creep from the $462–$473 range toward the $501–$547 zone by delaying your purchase. On routes of this distance and demand profile, fares historically firm up as departure approaches and seats in economy fill. Booking when you see a fare in the bottom quartile — at or below $462 — represents a demonstrably better-than-average outcome based on what this data shows.

The data doesn't surface a specific dominant carrier for this route, so carrier-level conclusions would be speculative. What the numbers do support is a straightforward strategy: set a fare alert targeting $462–$470, and treat anything above $490 as a signal to reassess timing rather than buy immediately. One honest caveat: 30 snapshots capture a single rolling window and may not reflect seasonal demand shifts — fares around Korean holidays or peak summer travel could push well outside this observed range.
