ASU to AEP questions
Is ASU–AEP running on time right now?
Some delays possible. The arrival side at AEP is the weaker end, route health score 54/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ASU to AEP?
Great-circle distance is 1,040 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 103–119 min gate-to-gate on this route.
How often does ASU–AEP fly?
3 carriers operate this route, around 21 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 ASU 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.
