SAT to SFO questions

Is SAT–SFO running on time right now?

Smooth skies ahead. The departure side at SAT is the weaker end, route health score 93/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from SAT to SFO?

Great-circle distance is 2,382 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 198–234 min gate-to-gate on this route.

How often does SAT–SFO fly?

4 carriers operate this route, around 27 flights a week between them. Compare carrier days and times in the airline list above.

What does the route health score measure?

A blend of departure-side delay at SAT and arrival-side delay at SFO, computed from rolling delay windows (refreshed every 40 minutes) with a daily-rollup fallback. Current MVFR, IFR, or LIFR endpoint weather caps the score when flight rules can limit throughput. Higher is healthier: 100 means operations are clean at both ends.
