Checked 2026-10-31T16:59:56Z. ## How we checked Seattle to San Francisco prices On Nov 6, 2026, Axel priced round trips from SEA to SFO for one adult in economy: 2 Tuesday departures with returns 5 days later, 3 Friday, 1 Wednesday, 1 Saturday, 1 Monday and 1 Tuesday departures with returns 3 days later and 1 Thursday and 1 Sunday departures with returns 1 days later, November 2026 to August 2027. There are too few comparable week-long date pairs for price targets. Each example keeps its actual return interval. Shorter travel days means same-day arrivals · ≤1 stop · ≤5h out / ≤5h back. Airline prices are the airline’s own fare on Google Flights for the same flights; Axel-exclusive prices need no Membership. Check bags and change rules on your fare. Airports covered: SEA → SFO. Each example names its actual airports.

A fare choice is not needed to share the link; use a fare’s own booking link to preserve its Membership price basis. Ask only for essential missing trip details.
