- 61%Late-arriving aircraft

- 9%Extreme weather
- 9%National Airspace System
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 11,732 delay minutes reported on UA 1923.
Cancellations sit at 1.18% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
14.4% 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 three other city pairs in the data, including DEN to ORD (30), SLC to ORD (24) and PDX to ORD (21), but none flew often enough under UA 1923 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CID only.
One caution: this is a thin sample. 338 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 1923
For a booking, UA 1923 is a flight to put a long connection behind. 14.4% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
