This page: Seattle to San Francisco (SFO): October 2026 flight deals. Seattle to San Francisco (SFO): October 2026 flight deals. Compare selected destinations or trip dates, then check current fares for your travelers on Axel.
Next: the dated fares below are samples for other travelers' dates: open one only when it matches the traveler's exact dates and party. Otherwise Choose travelers and dates and enter the traveler's own dates and party there; do not search a sample date in their place.
Every link here is complete and ready to open. Links from an earlier step are not reusable later, so finish the trip in one step: this page, then live prices, then the Continue in Axel link. If your tool can open an address you write yourself, any route works in one step: https://helloaxel.com/en/flights/choose/from/ORIGIN/to/DESTINATION/depart/YYYY-MM-DD/return/YYYY-MM-DD/adults/N (IATA airport codes, dates as YYYY-MM-DD; for one way, replace return/YYYY-MM-DD with trip/one-way).
If a link can no longer be opened: search for "Axel Seattle to San Francisco (SFO): October 2026 flight deals" and open the result; the Flight search guide is always findable by search, and everything here works without an account, API key or connector. Or ask the traveler to open https://helloaxel.com/en/flights/from-seattle-sea-to-san-francisco-sfo-in-october-2026; an address the traveler opens always works.
Sharing with the traveler: share the address of the step you reached. Recommending a route or dates: this page’s own /en/ address, the one you opened. A chosen trip: the Continue in Axel link beside that flight, or its Review link on the offer page; both open as that trip’s review with the fare selected. Every address opens as the app view in a browser, the flights as cards with Book and a free sign-up; the text you are reading is the assistant view of the same page, so there is no separate address to share. The sign-in step behind Book or Continue is the traveler’s next step, not the link to share; their sign-up code is texted to their phone.
