DAY to DEN questions

Is DAY–DEN running on time right now?

Some delays possible. Both endpoints currently score the same, route health score 66/100. The airports section above carries the live status and delay window at both ends.

How long is the flight from DAY to DEN?

Great-circle distance is 1,741 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 153–179 min gate-to-gate on this route.

How often does DAY–DEN fly?

United Airlines runs the route with about 7 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 DAY and arrival-side delay at DEN, 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.
