Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3304, 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 3304 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 289 flights, with a median arrival 13 minutes early.

Set against the rest of the country, OO 3304's record is 15 points better than the US average of 77.6%. That gap is worth roughly 154 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 3304 flies

OO 3304 is scheduled to leave Pasco (PSC) at 07:00 local time and reach Los Angeles (LAX) at 09:48. That slot held for 250 of the 289 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

  • Departs 07:00250 flights86.5%
  • Departs 07:0237 flights12.8%

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 3304 runs 4 points better at 93.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

Across the year

OO 3304 quarter by quarter

OO 3304 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Apr–Jun 2026 at 85.7%, a swing of 12 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.

  • Jul–Sep 202592 flights97.8%
  • Oct–Dec 202556 flights94.5%
  • Jan–Mar 202678 flights92.1%
  • Apr–Jun 202663 flights85.7%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 3304 did best on Monday at 97.6% on time and worst on Saturday at 85.0%. Each day rests on about 41 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3304 runs late

One category carries most of the weight here. Carrier accounts for 82% of the 903 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.

  • Carrier
    82%
  • Extreme weather
    15%
  • National Airspace System
    3%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 903 delay minutes reported on OO 3304.

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

Badly late arrivals are rare here: only 1.4% 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 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 two other city pairs in the data, including PHX to SFO (20) and SEA to FAT (12), but none flew often enough under OO 3304 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PSC to LAX 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 3304

For a booking, OO 3304 has one of the better records a US domestic flight can show: 93.0% on time and 0.69% cancelled. That is a base rate, not a promise about any single day.
