Delay causes
Why UA 1492 runs late
Late-arriving aircraft accounts for 54% of the 9,617 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 26%Carrier
- 16%National Airspace System
- 4%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,617 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 9,617 delay minutes reported on UA 1492.
Cancellations run at 2.75%, against 1.89% nationally. That is roughly one flight in 40 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
14.1% 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 two other city pairs in the data, including CMH to SFO (3) and PHX to ORD (3), but none flew often enough under UA 1492 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. 364 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 UA 1492
For a booking, the cancellation rate is the figure to plan around on UA 1492: 2.75% of its 364 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.
