Conditions are tightest at SEA: a 30% chance of a 15+ minute delay. In this weather, the more delayed of the two airports is typically about +1 min. Both figures come from the two airports' delay records in similar weather. See live delays → · Weather risk by airport →

How the Amsterdam to Seattle route actually runs
Pro Flight Search records official board updates for nonstop AMS to SEA 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.

AMS to SEA questions
Is AMS–SEA running on time right now?
Smooth skies ahead. The departure side at AMS is the weaker end, route health score 87/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from AMS to SEA?
Great-circle distance is 7,840 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 583–702 min gate-to-gate on this route.
How often does AMS–SEA fly?
Delta Air Lines runs the route with about 14 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 AMS and arrival-side delay at SEA, 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.
