IND to BEG questions
Is IND–BEG running on time right now?
Smooth skies ahead. The arrival side at BEG is the weaker end, route health score 90/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from IND to BEG?
Great-circle distance is 8,103 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 602–725 min gate-to-gate on this route.
How often does IND–BEG fly?
Allegiant Air runs the route with about 1 flight a week (fri). 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 IND and arrival-side delay at BEG, 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.
