Delay causes
Why MQ 3694 runs late
Late-arriving aircraft accounts for 59% of the 8,131 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 17%Carrier
- 16%National Airspace System
- 8%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,131 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 8,131 delay minutes reported on MQ 3694.
Cancellations run at 3.79%, against 1.89% nationally. That is about one flight in 25 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
17.7% 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.
Every one of the 317 flights under MQ 3694 in the data flew ORD to CMI. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 317 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 3694
For a booking, the cancellation rate is the figure to plan around on MQ 3694: 3.79% of its 317 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.
