How the Washington to La Crosse route actually runs
Pro Flight Search records official board updates for nonstop DCA to LSE 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.

DCA to LSE questions
Is DCA–LSE running on time right now?
Mostly on schedule. The departure side at DCA 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 DCA to LSE?
Great-circle distance is 1,309 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 122–142 min gate-to-gate on this route.
How often does DCA–LSE fly?
Sun Country Airlines runs the route with about 1 flight a week (mon). 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 DCA and arrival-side delay at LSE, 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.
