|---|---|---|
| 19 January 2026 | 17 hours 12 minutes | Carrier |
| 6 December 2025 | 6 hours 31 minutes | Carrier |

Delay causes
Why OO 3783 runs late
Carrier accounts for 55% of the 6,088 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 28%Extreme weather
- 15%National Airspace System
- 1%Security
Extreme weather accounts for 28% 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 4.7 times the usual weather exposure. The split is drawn from 6,088 delay minutes reported on OO 3783.
Cancellations sit at 1.31% against a national 1.89%, which is ordinary. Diversions add another 0.66%.
Connections and routes
What a delay on this flight costs
11.0% 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.
The 907 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
OO 3783 is not only a IAD to MSP flight. It also flew MSP to IAD (304 flights, 78.5% 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. 305 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.
