How the Portland to Denver route actually runs
Pro Flight Search records official board updates for nonstop PWM to DEN flights through the day: schedules, estimates, gate pushes and actual departures. The verdict above comes from operated flights, so it reflects what this route does rather than what the timetable promises.

PWM to DEN questions
Is PWM–DEN running on time right now?
Mostly on schedule. The departure side at PWM is the weaker end, route health score 70/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from PWM to DEN?
Great-circle distance is 2,861 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 232–275 min gate-to-gate on this route.
How often does PWM–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 PWM 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.
