The following airlines operate direct flights on the route Seoul — Seattle: Korean Air, Alaska Airlines, Asiana Airlines
Incheon International Airport (ICN) serves as Seoul’s primary international gateway and a major regional hub, handling most long-haul and premium carriers along with many full-service Asian airlines. It’s located about 48 km west of central Seoul, with travel times typically around 45–70 minutes by airport express train (AREX) or 60–90 minutes by airport limousine bus depending on traffic; fares for rail and buses usually sit within a moderate range. Taxis can be faster but costlier. ICN is known for modern facilities, extensive lounges, and shopping, though its distance from downtown can add transfer time. Gimpo International Airport (GMP) acts as Seoul’s nearer, more domestic- and short-haul-focused airport, commonly serving budget carriers, domestic flights and select regional routes to Japan and China. It’s roughly 15–20 km from central Seoul, typically 20–40 minutes away by subway or 30–60 minutes by bus; fares are usually low to moderate. Gimpo can be more convenient for quick city access and shorter transfers, but it offers fewer long-haul services and amenities than Incheon.
Seattle is served primarily by Seattle–Tacoma International (SEA), the region’s main international hub that typically handles most long-haul and premium carriers, while smaller Boeing Field (BFI) and Paine Field (PAE) cater to some domestic, corporate and low-cost services. SEA sits about 14 miles south of downtown Seattle; travelers can reach the city center by Link light rail in roughly 35–45 minutes for a modest fare, by highway shuttle or taxi in 20–40 minutes depending on traffic (fares vary), or by rental car. SEA is generally seen as mid- to upper-range on convenience with full facilities and multiple lounges; downsides can include peak-time congestion and occasional security queues. BFI/PAE can be quicker for some local or budget flights but have fewer public-transit options and limited amenities.
