Delay causes
Why OO 4291 runs late
Carrier accounts for 77% of the 9,282 delay minutes carriers reported here, and the remaining four split what is left.
- 77%Carrier
- 19%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 19% 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 3.2 times the usual weather exposure. The split is drawn from 9,282 delay minutes reported on OO 4291.
Cancellations sit at 2.20% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
8.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 2.9 hours, which a normal layover absorbs.
Every one of the 363 flights under OO 4291 in the data flew MSP to BJI. 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. 363 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.
