|---|---|---|
| 13 June 2026 | 16 hours 47 minutes | Carrier |
| 9 November 2025 | 8 hours 7 minutes | Carrier |

Delay causes
Why OO 4236 runs late
Carrier accounts for 74% of the 5,908 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Carrier
- 21%Extreme weather
- 4%National Airspace System
- 2%Security
Extreme weather accounts for 21% 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 3.4 times the usual weather exposure. The split is drawn from 5,908 delay minutes reported on OO 4236.
Cancellations are rare at 0.75%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
11.4% 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 4236 is not only a HIB to MSP flight. It also flew MSP to HIB (266 flights, 79.7% 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. 266 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.
