Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4701, 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 4701 lands a B+, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 331 flights, with a median arrival 1 minute early.

These figures cover 331 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Schedule
When OO 4701 flies
OO 4701 flies DEN to RDD without a single fixed slot. Its most common scheduled departure was 11:45, used on 62 of 331 flights, with 11:26 (56 flights) and 11:44 (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 11:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4701 runs level with that at 77.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
OO 4701 quarter by quarter
OO 4701 did not run the same all year. Its best quarter was Jul–Sep 2025 at 85.7% on time and its weakest Apr–Jun 2026 at 68.9%, a swing of 17 points on roughly 83 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 202584 flights85.7%
- Oct–Dec 202566 flights76.9%
- Jan–Mar 202690 flights77.8%
- Apr–Jun 202691 flights68.9%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, OO 4701 did best on Thursday at 84.8% on time and worst on Friday at 63.8%. Each day rests on about 47 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 4701 runs late
One category carries most of the weight here. Carrier accounts for 48% of the 3,721 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.
- 48%Carrier
- 32%Late-arriving aircraft
- 17%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 48%, 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 1,802 of the 3,721 delay minutes reported here. The split is drawn from 3,721 delay minutes reported on OO 4701.
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
6.1% 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 50 minutes, which a normal layover absorbs.
The 932 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 CAE to ORD (25), BZN to LAX (1) and RNO to SFO (1), but none flew often enough under OO 4701 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RDD only.
One caution: this is a thin sample. 331 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.
