MAA to BWN questions
How long is the flight from MAA to BWN?
Great-circle distance is 3,916 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 306–366 min gate-to-gate on this route.
How often does MAA–BWN fly?
Royal Brunei Airlines runs the route with about 2 flights a week (tue, sat). 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 MAA and arrival-side delay at BWN, 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.
