Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5490, 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.

These figures cover 309 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 5490 flies

OO 5490 flies OKC to DEN without a single fixed slot. Its most common scheduled departure was 11:15, used on 127 of 309 flights, with 11:30 (87 flights) and 11:25 (58 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 11:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5490 runs 5 points better at 84.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5490 quarter by quarter

OO 5490 did not run the same all year. Its best quarter was Jul–Sep 2025 at 88.4% on time and its weakest Jan–Mar 2026 at 78.4%, a swing of 10 points on roughly 77 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 flights85.7%
Jan–Mar 202690 flights78.4%

By weekday, OO 5490 ranged from 81.1% on Saturday to 88.6% on Sunday. With about 44 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 5490 runs late

One category carries most of the weight here. Carrier accounts for 79% of the 3,694 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.

Extreme weather
0%

The largest share of delay minutes, 79%, 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 2,912 of the 3,694 delay minutes reported here. The split is drawn from 3,694 delay minutes reported on OO 5490.

Cancellations sit at 0.97% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.9% 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 three other city pairs in the data, including MSP to SFO (34), PHX to SFO (1) and MSN to DEN (1), but none flew often enough under OO 5490 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to OKC to DEN only.

One caution: this is a thin sample. 309 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.
