FAA
Ground delay program
The FAA is metering arrivals into SEA by assigning inbound flights a departure delay before they leave. That assigned delay is not the same thing as how late flights end up running.
- Average assigned delay
- 39 min
- Maximum assigned delay
- 1 hr 47 min

Good flying weather
VFR — clear enough to fly visually

Later today
No major FAA traffic programs are currently planned for SEA, as of the latest FAA Operations Plan. That is a plan, not a promise.
What this means
The FAA is metering arrivals rather than stopping them, so flights are moving, just slower than scheduled.
Individual flights can still be delayed or cancelled when the airport looks fine. Check your airline for your actual flight.

Usually at this time
80%
of SEA departures left on time on a typical Monday, across 26,983 flights. Monday evening performs about normally for SEA.
Historical departure punctuality from U.S. Bureau of Transportation Statistics, June 2025 – May 2026. This is a separate measurement from anything above: the FAA's delay figures describe traffic-management actions taken today, and averaging the two together would produce a number that means nothing. A ground stop is still a ground stop on an airport's best weekday.
Flying out soon?
