Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4301, 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 4301 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%. When something does go wrong the average delay runs an hour and a half. That rests on 362 flights, with a median arrival 12 minutes early.

Set against the rest of the country, OO 4301's record is 7 points better than the US average of 77.6%. That gap is worth roughly 67 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% 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 4301 flies

OO 4301 flies MSP to BRD without a single fixed slot. Its most common scheduled departure was 17:55, used on 91 of 362 flights, with 16:45 (67 flights) and 16:40 (55 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 17:55 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 4301 runs 16 points better at 84.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 4301 quarter by quarter

OO 4301 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.3% on time and its weakest Oct–Dec 2025 at 76.7%, a swing of 17 points on roughly 91 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 202589 flights76.7%
Jan–Mar 202690 flights83.0%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 4301 ranged from 76.9% on Friday to 86.5% on Monday. With about 52 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 4301 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 5,211 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
60%
Extreme weather
30%
National Airspace System
9%

Extreme weather accounts for 30% 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 4.9 times the usual weather exposure. The split is drawn from 5,211 delay minutes reported on OO 4301.

Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.1% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including BRD to MSP (248), but none flew often enough under OO 4301 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MSP to BRD only.

One caution: this is a thin sample. 362 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.
