Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3791, 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 3791 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 364 flights, with a median arrival 5 minutes early.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OO 3791 flies

OO 3791 flies MSP to OKC without a single fixed slot. Its most common scheduled departure was 18:10, used on 145 of 364 flights, with 18:15 (134 flights) and 18:20 (68 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 18:10 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 3791 runs 9 points better at 77.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

By weekday, OO 3791 did best on Wednesday at 82.7% on time and worst on Sunday at 66.0%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3791 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 5,507 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.

Carrier
50%
Extreme weather
39%
National Airspace System
11%

Extreme weather accounts for 39% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 6.3 times the usual weather exposure. The split is drawn from 5,507 delay minutes reported on OO 3791.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 1.10%.

Connections and routes

What a delay on this flight costs

8.4% 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 694 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 ATL to LEX (1), but none flew often enough under OO 3791 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to OKC 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.
