SFO to Seoul: KE vs UA Polaris — 2026 Route Review
San Francisco to Seoul Incheon is a roughly 12-hour, 5,600-nautical-mile nonstop now operated daily by Korean Air and United, with Asiana service consolidated into Korean post-merger. We flew both carriers in 2026 — Korean Air on 787-10 with Prestige Suites 2.0 and on 777-300ER with Apex Suites, plus United Polaris on a 777-300ER refresh and a 787-9 — and compared cabin, ground experience, redemption math, and where this route sits versus LAX-ICN and JFK-ICN.
