These figures cover 279 flights between September 2025 and August 2026. The median arrival is 14 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 3302 runs late
Late-arriving aircraft accounts for 46% of the 2,609 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 41%National Airspace System
- 10%Carrier
- 3%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,609 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 2,609 delay minutes reported on OO 3302.
Cancellations run at 9.32%, against 1.89% nationally. That is about one flight in ten 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
7.2% 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 roughly 45 minutes, which a normal layover absorbs.
The 508 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 279 flights under OO 3302 in the data flew SAN to STS. 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. 279 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 3302
For a booking, the cancellation rate is the figure to plan around on OO 3302: 9.32% of its 279 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
