Delay causes
Why OH 5656 runs late
Late-arriving aircraft accounts for 55% of the 8,957 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 37%Carrier
- 5%National Airspace System
- 3%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,957 reported delay minutes here, that single category outweighs weather by 18 to one. The split is drawn from 8,957 delay minutes reported on OH 5656.
Cancellations run at 12.39%, against 1.89% nationally. That is about one flight in eight cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
15.5% 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.
The 634 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.
The same number turns up on three other city pairs in the data, including BTR to DFW (2), DCA to CMH (1) and DCA to TLH (1), but none flew often enough under OH 5656 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to MKE only.
One caution: this is a thin sample. 347 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.
What to do with this
Booking OH 5656
For a booking, the cancellation rate is the figure to plan around on OH 5656: 12.39% of its 347 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
