Delay causes
Why OO 3298 runs late
Late-arriving aircraft accounts for 70% of the 2,996 delay minutes carriers reported here, and the remaining four split what is left.
- 70%Late-arriving aircraft
- 24%Carrier
- 4%National Airspace System
- 2%Extreme weather
70% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,996 reported delay minutes here, that single category outweighs weather by 31 to one. The split is drawn from 2,996 delay minutes reported on OO 3298.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 50 minutes, which a normal layover absorbs.
The 689 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on one other city pair in the data, including PDX to GEG (59), but none flew often enough under OO 3298 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to SLC only.
One caution: this is a thin sample. 294 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
