Delay causes
Why UA 1568 runs late
Late-arriving aircraft accounts for 51% of the 8,265 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 23%Carrier
- 20%National Airspace System
- 5%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,265 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 8,265 delay minutes reported on UA 1568.
Cancellations sit at 1.28% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.4% 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 528 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 two other city pairs in the data, including SFO to ORD (220) and DSM to ORD (105), but none flew often enough under UA 1568 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to ROC only.
One caution: this is a thin sample. 312 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.
