Delay causes

Why OO 4266 runs late

Carrier accounts for 72% of the 5,757 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
72%
Extreme weather
23%
National Airspace System
5%

Extreme weather accounts for 23% 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 3.8 times the usual weather exposure. The split is drawn from 5,757 delay minutes reported on OO 4266.

Cancellations sit at 1.03% against a national 1.89%, which is ordinary. Diversions add another 0.34%.

Connections and routes

What a delay on this flight costs

11.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

OO 4266 is not only a MSP to INL flight. It also flew INL to MSP (290 flights, 85.7% 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. 290 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.
