How the Washington to Moline route actually runs
Pro Flight Search records official board updates for nonstop IAD to MLI 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.

IAD to MLI questions
Is IAD–MLI running on time right now?
High disruption likely. The departure side at IAD is the weaker end, route health score 0/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from IAD to MLI?
Great-circle distance is 1,142 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 111–128 min gate-to-gate on this route.
How often does IAD–MLI fly?
Sun Country Airlines runs the route with about 1 flight a week (wed). 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 IAD and arrival-side delay at MLI, 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.
