BOS to CPS questions
How long is the flight from BOS to CPS?
Great-circle distance is 1,670 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 148–173 min gate-to-gate on this route.
What does the route health score measure?
A blend of departure-side delay at BOS and arrival-side delay at CPS, 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.
