How the Idaho Falls to Seattle route actually runs
Pro Flight Search records official board updates for nonstop IDA 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.

IDA to SEA questions
Is IDA–SEA running on time right now?
Mostly on schedule. Both endpoints currently score the same, route health score 78/100. The airports section above carries the live status and delay window at both ends.
How long is the flight from IDA to SEA?
Great-circle distance is 909 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 94–108 min gate-to-gate on this route.
How often does IDA–SEA fly?
Alaska Airlines 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 IDA 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.
