Which airlines fly San Francisco to Seoul nonstop

The cheapest way to fly San Francisco to Seoul by phone
3 checks set a San Francisco to Seoul fare: the departure date, Korean Air against Asiana, and the Taipei one-stop beside both nonstops. The 2 carriers land at Incheon in about 12 hours, split across SkyTeam and Star, so the same calendar date prices differently on each network. Departing mid-week prices below weekend peaks on transpacific calendars. The agent runs the comparison on your exact dates; the process is on the cheap flight deals by phone page.
One-stop routings that often beat the nonstop price
The one-stop against both San Francisco to Seoul nonstops is EVA Air via Taipei Taoyuan. SFO–TPE–Seoul flies Star Alliance, the same family as Asiana, while the Korean Air nonstop runs SkyTeam, so the 3 routings span 2 alliances with different fare bases. Peak Korea dates price the one-stop below both nonstops; the gap closes back up on off-peak dates. First stays on the Korean Air nonstop, and the agent quotes all 3 with total travel time before you pick.
Last-minute seats on San Francisco to Seoul
Last-minute San Francisco to Seoul seats come from the Korean Air and Asiana nonstops plus the Taipei one-stop, priced within the final 72 hours. Late transpacific pricing favors flexibility on the departure bank and the carrier spread: an early SFO departure against a red-eye, Star against SkyTeam. The agent sweeps all 3 routings, quotes the workable totals with taxes in, and tickets before the fare closes. The playbook is on the last-minute flights by phone page.
Round trip and return-date strategy
Free cancellation within 24 hours under the DOT rule covers a San Francisco to Seoul round trip booked 7+ days before departure. The agent prices the round trip and the 2 one-way tickets on your dates and reads both totals aloud. The ~12-hour SFO run usually prices lower as a round trip, the return leg stays movable under the fare rules, and later return-date moves follow the fee logic on the flight cancellation and refunds by phone page.
