Pro Flight Search records official board updates for nonstop LIR 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.

LIR to DEN questions
Is LIR–DEN running on time right now?
High disruption likely. The arrival side at DEN is the weaker end, route health score 18/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from LIR to DEN?
Great-circle distance is 3,762 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 296–352 min gate-to-gate on this route.
How often does LIR–DEN fly?
United Airlines runs the route with about 1 flight a week (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 LIR 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.
