About this route

Los Angeles (LAX) to Seoul (ICN) is one of the long-haul trunk routes behind our notable flights, flown daily by competing carriers. Flown by KE12. It links Los Angeles International Airport in United States with Incheon International Airport in South Korea. The great-circle distance is about 5,197 nautical miles (5,982 statute miles), so expect roughly 12 hours in the air nonstop.

Every night we ask our fare provider for the cheapest one-way economy fare other travellers recently found on this route and record it, with the airline and the seller it was found with. A fare is flagged as a deal when it falls at least 30% below the route's 90-day typical price. Prices are a research starting point, not live availability — the booking links open the itinerary so you can confirm what's on sale right now. business class fares aren't priced by our provider, so that section links to live searches instead.

Fares are approximate, from public sources, and can be stale — always verify before booking.
