ONT to JFK questions

Is ONT–JFK running on time right now?

Mostly on schedule. The departure side at ONT is the weaker end, route health score 70/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from ONT to JFK?

Great-circle distance is 3,901 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 305–364 min gate-to-gate on this route.

How often does ONT–JFK fly?

JetBlue Airways 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 ONT and arrival-side delay at JFK, 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.
