| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 August 2026 | 7 hours 50 minutes | Late-arriving aircraft |
| 20 May 2026 | 7 hours 25 minutes | Late-arriving aircraft |

Delay causes
Why UA 514 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,323 reported delay minutes.
- 37%Late-arriving aircraft
- 31%Carrier
- 25%National Airspace System
- 7%Extreme weather
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,323 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 6,323 delay minutes reported on UA 514.
Cancellations are rare at 0.65%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.9% 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 692 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 five other city pairs in the data, including DEN to SDF (77), DEN to DCA (31) and BUF to ORD (24), but none flew often enough under UA 514 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CID to DEN only.
One caution: this is a thin sample. 307 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 514
For a booking, read UA 514 as 77.6% on time with 0.65% cancelled over 307 flights. Those are rates from the past twelve months, not a forecast for any particular day.
