Which airlines fly Seattle to Seoul nonstop

The cheapest way to fly Seattle to Seoul by phone
3 levers drop a Seattle to Seoul fare: shifting departure a day or 2 off-peak, comparing Asiana against Korean Air on identical dates, and adding the Taipei one-stop to the search. Mid-week departures price below weekend peaks on transpacific calendars, and the 2-carrier nonstop competition keeps both alliances quoting sharp on this city pair. The full search process lives on the cheap flight deals by phone page; exact totals shift daily, so the agent quotes your dates by phone.
One-stop routings that often beat the nonstop price
EVA Air via Taipei is the one-stop routing that prices against the 2 Seattle nonstops. The Taipei Taoyuan connection trades the ~12 h nonstop for a 2-leg trip in Star Alliance hands — the same alliance as Asiana — so the comparison against the Asiana nonstop runs closest on mileage earning. Peak Korea dates price the one-stop below both nonstops; off-peak dates tighten the gap. The agent quotes both structures with layover length before you decide.
Last-minute seats on Seattle to Seoul
Last-minute Seattle to Seoul seats come from the 2 nonstop carriers and the Taipei one-stop, priced inside the final 72 hours before departure. Late transpacific fares favor flexible travelers on carrier and departure time: Asiana against Korean Air, day against evening. The agent sweeps all 3 routings, quotes the workable options with taxes in, and tickets before the fare expires mid-call. Tactics live on the last-minute flights by phone page.
Round trip and return-date strategy
Round-trip Seattle to Seoul pricing usually beats 2 one-way tickets transpacific, and the return date stays movable under your fare rules. The agent runs the round trip against the 2 separate one-ways before quoting, so the cheaper structure wins by default. The DOT 24-hour rule adds a free-exit window: tickets bought 7+ days before departure cancel free within 24 hours of purchase if plans flip right after booking. Return-date moves after that follow the fee logic on the flight cancellation and refunds by phone page.
