CLT to ONT questions

Is CLT–ONT running on time right now?

Mostly on schedule. The arrival side at ONT is the weaker end, route health score 79/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from CLT to ONT?

Great-circle distance is 3,337 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 266–316 min gate-to-gate on this route.

How often does CLT–ONT fly?

American Airlines runs the route with about 7 flights a week (daily). 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 CLT and arrival-side delay at ONT, 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.
