The Chicago–Seoul route
ORD–ICN is a long-haul pairing from the United States to Seoul: roughly 6,538 miles. Nonstop ORD–ICN is often on the schedule, about 13 hours airborne over 6,538 miles. Overnight westbound is common; compare arrival local time, not only the duration field.
For ORD–ICN we show about $539 on the low end and around $960 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $539 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.

Distance and time ORD–ICN
Great-circle distance ORD–ICN is about 6,538 miles. Block time on a nonstop is typically near 13 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 Chicago 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 ORD–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 Chicago to Seoul
You depart O'Hare International in Chicago, United States, and arrive at Incheon International in Seoul, South Korea. ORD 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.
Near Chicago, also compare MDW (Chicago). 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.
