Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3302, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
OO 3302 lands a B−, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 40 minutes on average. That is a workable record, not a spotless one. That rests on 269 flights, with a median arrival 14 minutes early.

These figures cover 269 flights between July 2025 and June 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.
Schedule
When OO 3302 flies
OO 3302 flies SAN to STS without a single fixed slot. Its most common scheduled departure was 21:59, used on 100 of 269 flights, with 21:14 (52 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 21:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 3302 runs 11 points better at 81.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
OO 3302 quarter by quarter
Quarter by quarter OO 3302 held fairly steady: 77.6% in Jul–Sep 2025, 78.2% in Oct–Dec 2025, 81.0% in Jan–Mar 2026 and 85.2% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202549 flights77.6%
- Oct–Dec 202568 flights78.2%
- Jan–Mar 202670 flights81.0%

By weekday, OO 3302 did best on Wednesday at 100.0% on time and worst on Sunday at 62.8%. Each day rests on about 38 flights, so a gap of 37 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 3302 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 1,971 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 49%Late-arriving aircraft
- 39%National Airspace System
- 11%Carrier
- 2%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,971 reported delay minutes here, that single category outweighs weather by 27 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,971 delay minutes reported on OO 3302.
Cancellations run at 7.43%, against 1.81% nationally. That is roughly one flight in twelve 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 4.0% land an hour or more behind schedule, against 8.1% 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 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 269 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. 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 3302
For a booking, the cancellation rate is the figure to plan around on OO 3302: 7.43% of its 269 scheduled flights did not operate. A late arrival costs roughly 40 minutes, but a cancellation costs the day, so leave a later option open.
