How often does ISP–PBI fly?

What does the route health score measure?

A blend of departure-side delay at ISP and arrival-side delay at PBI, 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.
