CUN to BNA questions

Is CUN–BNA running on time right now?

Smooth skies ahead. The departure side at CUN is the weaker end, route health score 93/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from CUN to BNA?

Great-circle distance is 1,678 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 148–174 min gate-to-gate on this route.

How often does CUN–BNA fly?

Southwest Airlines runs the route with about 5 flights a week (sun, mon, thu, fri, 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 CUN and arrival-side delay at BNA, 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.
