How long is the flight from CPC to AEP?

Great-circle distance is 1,280 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 120–140 min gate-to-gate on this route.

How often does CPC–AEP fly?

2 carriers operate this route, around 17 flights a week between them. Compare carrier days and times in the airline list above.

What does the route health score measure?

A blend of departure-side delay at CPC and arrival-side delay at AEP, 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.
