About this route

Bangkok (BKK) to Seoul (ICN) is one of the busiest air routes in its market (Asia-Pacific). It links Suvarnabhumi Airport in Thailand with Incheon International Airport in South Korea. The great-circle distance is about 1,981 nautical miles (2,280 statute miles), so expect roughly 5 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.

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