Delay causes
Why OO 4229 runs late
Carrier accounts for 50% of the 2,711 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 39%Extreme weather
- 10%National Airspace System
- 1%Security
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 6.5 times the usual weather exposure. The split is drawn from 2,711 delay minutes reported on OO 4229.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.3% 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 an hour, which a normal layover absorbs.
OO 4229 is not only a MSP to HIB flight. It also flew HIB to MSP (364 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. 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.
