Flying Seattle to Seoul covers about 5,200 miles, linking Seattle-Tacoma International Airport (SEA) with Incheon International Airport (ICN); a nonstop takes roughly 10h55, with winds moving it either way. Nonstop award space in the data comes from Alaska Airlines, Korean Air, and Delta. The Airbus A350-900, Boeing 787-10, and Boeing 787-9 all appear on those nonstop award segments. Most award options in the data connect. Nonstops are just about 3% of the total.
Seattle–Seoul is a long-haul trip, so cabin choice shapes the whole booking. The cheapest economy seat is an Alaska Airlines nonstop booked through the airline's own program, so saving points costs no extra time. Its listed taxes, about $6, look incomplete for an international departure, so confirm the cash cost at checkout. Stepping up costs about triple the economy points for premium economy and about 5 times for business. Hold off on converting flexible points until the seat is confirmed bookable; there's no undoing a transfer.
Alaska Atmos Rewards takes economy at 20,000 points on an Alaska Airlines nonstop. Air Canada Aeroplan is cheapest in premium economy at 60,000 points. Avianca LifeMiles wins business class at 100,000 points. First class starts at 106,000 points through Virgin Atlantic Flying Club on a connecting itinerary, often first on one leg only, so confirm the cabin on each flight.
On points, Seattle–Seoul has nonstop seats from Alaska Airlines (oneworld), Korean Air (SkyTeam), and Delta (SkyTeam), which puts partner programs from both alliances in play for a nonstop. If you're open to a stop, the better-priced connecting awards in the data run through Vancouver, Taipei, and San Francisco. The business-class floor is a Star Alliance partner award: Avianca LifeMiles prices EVA Airways seats.
