These figures cover 289 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 3303 runs late
Late-arriving aircraft accounts for 43% of the 2,288 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 27%National Airspace System
- 23%Carrier
- 6%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,288 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 2,288 delay minutes reported on OO 3303.
Cancellations are rare at 0.69%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.9% 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 851 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 three other city pairs in the data, including BLI to SEA (48), SFO to PHX (18) and OAK to PHX (1), but none flew often enough under OO 3303 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to PSC only.
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 OO 3303
For a booking, OO 3303 has one of the better records a US domestic flight can show: 88.2% on time and 0.69% cancelled. That is a base rate, not a promise about any single day.
