Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4717, 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 4717 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 251 flights, with a median arrival 6 minutes early.

Set against the rest of the country, OO 4717's record is 10 points better than the US average of 77.6%. That gap is worth roughly 97 fewer late arrivals for every thousand flights.

These figures cover 251 flights between July 2025 and June 2026. The median arrival is 6 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 4717 flies

OO 4717 flies MRY to LAX without a single fixed slot. Its most common scheduled departure was 07:00, used on 82 of 251 flights, with 06:00 (56 flights) and 07:45 (43 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 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 4717 runs 2 points worse at 87.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 4717 quarter by quarter

Quarter by quarter OO 4717 held fairly steady: 90.7% in Jul–Sep 2025, 89.9% in Oct–Dec 2025 and 82.2% in Jan–Mar 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, OO 4717 did best on Wednesday at 94.6% on time and worst on Sunday at 77.8%. Each day rests on about 36 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4717 runs late

One category carries most of the weight here. Carrier accounts for 82% of the 2,091 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
13%
National Airspace System
5%

Extreme weather accounts for 13% 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 2.0 times the usual weather exposure. The split is drawn from 2,091 delay minutes reported on OO 4717.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 3.6% 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 same number turns up on six other city pairs in the data, including GEG to ORD (48), BIL to DEN (30) and SFO to RDD (21), but none flew often enough under OO 4717 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MRY to LAX only.

One caution: this is a thin sample. 251 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 4717

For a booking, OO 4717 has one of the better records a US domestic flight can show: 87.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
