How to sanity-check cheap flights to San Francisco
Origin lead
Austin (AUS)
Keep one origin fixed for the first pass, then widen to other covered airports if the live fare is worse than expected.
Date window

Stop filter
2 nonstop-capable routes
Apply nonstop and one-stop filters inside live results before deciding which route is actually better.

Provider inventory, taxes, baggage, seats, and refunds decide the final checkout cost.

Destination-discovery move
Start from Austin (AUS)

Origin evidence depth
6 origins / 8 cached samples
6 routes feed this SFO watchlist; use the spread to choose what to recheck first, not as live-price proof.
Main destination-discovery risk
The cheapest origin may not win
A low cached lead can lose after schedule, baggage, airport access, connection risk, or trip dates are applied. Compare at least one alternate origin when the fare gap is small.
Best destination follow-up
Open cheapest months to SFO
Use the SFO month guide after the first origin shortlist so date flexibility drives the next search.
