Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3303, 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 3303 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 289 flights, with a median arrival 13 minutes early.

Set against the rest of the country, OO 3303's record is 10 points better than the US average of 77.6%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 289 flights between July 2025 and June 2026. The median arrival is 13 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 3303 flies

OO 3303 flies LAX to PSC without a single fixed slot. Its most common scheduled departure was 20:00, used on 65 of 289 flights, with 19:45 (56 flights) and 21:25 (49 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 20:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 3303 runs 17 points better at 87.1%. 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 3303 quarter by quarter

OO 3303 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.2% on time and its weakest Oct–Dec 2025 at 74.1%, a swing of 21 points on roughly 72 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OO 3303 did best on Wednesday at 97.6% on time and worst on Friday at 73.2%. Each day rests on about 41 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3303 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 2,168 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%
Carrier
25%
National Airspace System
19%
Extreme weather
7%

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 2,168 reported delay minutes here, that single category outweighs weather by 7 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 2,168 delay minutes reported on OO 3303.

Cancellations are rare at 0.69%, below the national 1.81% 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

5.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

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. 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.

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: 87.1% on time and 0.69% cancelled. That is a base rate, not a promise about any single day.
