These figures cover 289 flights between September 2025 and August 2026. The median arrival is 12 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 AS 589 runs late
Late-arriving aircraft accounts for 85% of the 625 delay minutes carriers reported here, and the remaining four split what is left.
- 85%Late-arriving aircraft
- 9%National Airspace System
- 5%Carrier
85% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 625 reported delay minutes here, that single category outweighs weather by 85 to one. The split is drawn from 625 delay minutes reported on AS 589.
Cancellations sit at 1.04% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.0% 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 859 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.
Every one of the 289 flights under AS 589 in the data flew SNA to PDX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 289 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 AS 589
For a booking, AS 589 has one of the better records a US domestic flight can show: 94.4% on time and 1.04% cancelled. That is a base rate, not a promise about any single day.
