These figures cover 269 flights between September 2025 and August 2026. The median arrival is 10 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes
Why OO 3460 runs late
Late-arriving aircraft accounts for 54% of the 752 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 38%Carrier
- 8%National Airspace System
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 752 reported delay minutes here, that single category outweighs weather by 54 to one. The split is drawn from 752 delay minutes reported on OO 3460.
Cancellations run at 3.35%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The same number turns up on one other city pair in the data, including SFO to LAX (18), but none flew often enough under OO 3460 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to BLI only.
One caution: this is a thin sample. 269 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.
What to do with this
Booking OO 3460
For a booking, the cancellation rate is the figure to plan around on OO 3460: 3.35% of its 269 scheduled flights did not operate. A late arrival costs roughly 30 minutes, but a cancellation costs the day, so leave a later option open.
