ROS to AEP questions
Is ROS–AEP running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from ROS to AEP?
Great-circle distance is 286 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 50–55 min gate-to-gate on this route.
How often does ROS–AEP fly?
AEROLINEAS ARGENTINAS runs the route with about 18 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 ROS 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.
