Looking for a one-way ticket from South Korea to Europe? China Southern currently has options from Seoul to Amsterdam starting at €915. These fares are available for travel from September to December 2026 and include 2×32 kg of checked baggage, lounge access, and more.
From Seoul to Beijing, the flights feature recliner seats, while the long-haul leg on the Airbus A350 offers lie-flat seats in a staggered 1-2-1 configuration. You can find available dates on Google Flights.
Alternatively, MIAT is worth considering. The Mongolian airline will fly you from Seoul to Frankfurt starting at €842. However, this option involves a 6-hour overnight layover in Ulaanbaatar and less time in a lie-flat seat.
