What the record says about this route
Which airline you fly changes the odds here. SkyWest Airlines arrived on time 10.6 points more often than Alaska Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
This route does better than its own airport. Departures from GEG overall run 10.1 points less punctual than this particular one — so whatever congestion GEG has, this route is largely escaping it.
Flights from Spokane to Seattle keep to schedule more reliably than most. On a route this punctual the day you fly matters more than the airline you pick.
This is a thin route — 375 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.
Which airline should you fly on this route?

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on GEG to SEA during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
