Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4713, 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 4713 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 364 flights, with a median arrival 16 minutes early.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 16 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 4713 flies
OO 4713 flies MRY to DEN without a single fixed slot. Its most common scheduled departure was 12:35, used on 227 of 364 flights, with 12:40 (48 flights) and 12:29 (41 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 12:35 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4713 runs 11 points better at 90.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 4713 quarter by quarter
OO 4713 did not run the same all year. Its best quarter was Jan–Mar 2026 at 95.5% on time and its weakest Jul–Sep 2025 at 80.9%, a swing of 15 points on roughly 91 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.

- Oct–Dec 202591 flights92.3%
- Jan–Mar 202690 flights95.5%

By weekday, OO 4713 did best on Saturday at 96.0% on time and worst on Tuesday at 83.0%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 4713 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 2,164 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.
- 45%Carrier
- 34%National Airspace System
- 16%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 982 of the 2,164 delay minutes reported here. The split is drawn from 2,164 delay minutes reported on OO 4713.
Cancellations are rare at 0.27%, 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 2.8% 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 959 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 one other city pair in the data, including BUR to DEN (1), but none flew often enough under OO 4713 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MRY to DEN only.
One caution: this is a thin sample. 364 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 4713
For a booking, OO 4713 has one of the better records a US domestic flight can show: 90.0% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
