Distance and time SFO–ICN
Great-circle distance SFO–ICN is about 5,646 miles. Block time on a nonstop is typically near 11.5 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Seoul is about 17 hours ahead of San Francisco on standard time (America/Los_Angeles vs Asia/Seoul). Arrival clocks on ICN are local. That matters more on this pair than on a same-zone hop.
When SFO–ICN has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
