Why fly Seattle to Seoul?
Seattle-Tacoma International to Seoul Incheon is a direct transpacific route operated by Korean Air, reflecting the Pacific Northwest's significant Korean-American community and strong trade relationship with South Korea. The 11-hour SEA–ICN service is one of the most under-the-radar premium routes from the US — Korean Air's business class cabin is a serious competitor to any carrier on this distance.
Premium cabin options on SEA–ICN
Korean Air's Prestige Class on the 787-9 Dreamliner from SEA features their reverse herringbone premium seat with direct aisle access and a strong Korean culinary programme. The full flat bed, excellent service, and Incheon's world-class airport transit facilities make this an exceptional experience compared to the route's relatively low profile.
