Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4273, 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 4273 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 267 flights, with a median arrival 16 minutes early.

Set against the rest of the country, OO 4273's record is 7 points better than the US average of 77.6%. That gap is worth roughly 68 fewer late arrivals for every thousand flights.

These figures cover 267 flights between July 2025 and June 2026. The median arrival is 16 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 4273 flies

OO 4273 flies BRD to MSP without a single fixed slot. Its most common scheduled departure was 10:55, used on 154 of 267 flights, with 11:05 (36 flights) and 11:00 (33 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 11:0536 flights13.5%
  • Departs 11:0033 flights12.4%

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:55 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4273 runs level with that at 84.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

OO 4273 quarter by quarter

Delay causes

Why OO 4273 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 3,904 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
    61%
  • Extreme weather
    31%
  • National Airspace System
    7%

Extreme weather accounts for 31% 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 5.0 times the usual weather exposure. The split is drawn from 3,904 delay minutes reported on OO 4273.

Cancellations sit at 1.87% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.9% 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 an hour and a half, which a normal layover absorbs.

OO 4273 is not only a BRD to MSP flight. It also flew MSP to BRD (267 flights, 86.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 267 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.
