Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5808, 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 5808 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%.

These figures cover 294 flights between July 2025 and June 2026. The median arrival is 12 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 5808 flies

OO 5808 flies DEN to OKC without a single fixed slot. Its most common scheduled departure was 13:40, used on 197 of 294 flights, with 13:37 (37 flights) and 13:35 (37 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 13:40 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5808 runs 6 points better at 84.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5808 quarter by quarter

OO 5808 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.6% on time and its weakest Jan–Mar 2026 at 77.3%, a swing of 15 points on roughly 74 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 5808 ranged from 78.0% on Thursday to 88.1% on Wednesday. With about 42 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 5808 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 3,273 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.

47%
Carrier
40%
National Airspace System
11%
Extreme weather
1%

47% 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 3,273 reported delay minutes here, that single category outweighs weather by 41 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 3,273 delay minutes reported on OO 5808.

Cancellations are rare at 0.34%, 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

6.8% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including CHA to ORD (29), but none flew often enough under OO 5808 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to OKC only.

One caution: this is a thin sample. 294 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 5808

For a booking, read OO 5808 as 84.3% on time with 0.34% cancelled over 294 flights. Those are rates from the past twelve months, not a forecast for any particular day.
