| 30 January 2026 | 4 hours 29 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3447 runs late
Late-arriving aircraft accounts for 59% of the 7,563 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 16%Carrier
- 15%National Airspace System
- 11%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,563 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 7,563 delay minutes reported on MQ 3447.
Cancellations run at 3.63%, against 1.89% nationally. That is roughly one flight in 30 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
15.9% 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 same number turns up on one other city pair in the data, including DSM to DFW (1), but none flew often enough under MQ 3447 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CMH only.
One caution: this is a thin sample. 303 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 MQ 3447
For a booking, the cancellation rate is the figure to plan around on MQ 3447: 3.63% of its 303 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
