SFO to SGN questions

Is SFO–SGN running on time right now?

Smooth skies ahead. The departure side at SFO is the weaker end, route health score 90/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from SFO to SGN?

Great-circle distance is 12,599 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 919–1110 min gate-to-gate on this route.

How often does SFO–SGN fly?

Vietnam Airlines runs the route with about 4 flights a week (sun, wed, thu, sat). Since one carrier owns the route, a single disruption tends to ripple through the day.

What does the route health score measure?

A blend of departure-side delay at SFO and arrival-side delay at SGN, 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.
