The Houston–Seoul route
IAH–ICN is a long-haul pairing from the United States to Seoul: roughly 7,052 miles. Nonstop IAH–ICN is often on the schedule, about 14 hours airborne over 7,052 miles. Overnight westbound is common; compare arrival local time, not only the duration field.
For IAH–ICN we show about $519 on the low end and around $940 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $519 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.
Search IAH to ICN on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time IAH–ICN
Great-circle distance IAH–ICN is about 7,052 miles. Block time on a nonstop is typically near 14 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Seoul is about 15 hours ahead of Houston on standard time (America/Chicago vs Asia/Seoul). Arrival clocks on ICN are local. That matters more on this pair than on a same-zone hop.
When IAH–ICN has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Houston to Seoul
You depart George Bush Intercontinental in Houston, United States, and arrive at Incheon International in Seoul, South Korea. IAH is the origin code we use on this guide; ICN is the arrival code. If you need a visa or an ESTA, that is between you and the destination government — Azurovia does not ticket and does not process immigration.
IAH is the only origin code we list in this metro. ICN is the arrival code we treat as primary for Seoul. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
