Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5324, 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 5324 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 11 points better than the national rate of 77.6%.

These figures cover 361 flights between July 2025 and June 2026. The median arrival is 11 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 5324 flies

OO 5324 flies DEN to OKC without a single fixed slot. Its most common scheduled departure was 10:05, used on 62 of 361 flights, with 10:02 (54 flights) and 09:59 (53 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 10:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5324 runs 5 points better at 88.6%. 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 5324 quarter by quarter

OO 5324 did not run the same all year. Its best quarter was Oct–Dec 2025 at 94.4% on time and its weakest Jan–Mar 2026 at 84.1%, a swing of 10 points on roughly 90 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 5324 ranged from 86.5% on Friday to 90.4% on Thursday. With about 52 flights behind each day, a spread of 4 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 5324 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 2,525 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
41%
Extreme weather
7%
National Airspace System
6%

45% 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 2,525 reported delay minutes here, that single category outweighs weather by 6 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 2,525 delay minutes reported on OO 5324.

Cancellations are rare at 0.28%, 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 2.5% 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.

Every one of the 361 flights under OO 5324 in the data flew DEN to OKC. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 361 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 5324

For a booking, OO 5324 has one of the better records a US domestic flight can show: 88.6% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
