| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 July 2026 | 11 hours 7 minutes | Carrier |
| 27 December 2025 | 8 hours 58 minutes | Late-arriving aircraft |
| 26 November 2025 | 8 hours 54 minutes | Carrier |

Delay causes
Why UA 1500 runs late
Carrier accounts for 63% of the 9,105 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Carrier
- 18%Extreme weather
- 10%Late-arriving aircraft
- 9%National Airspace System
Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.0 times the usual weather exposure. The split is drawn from 9,105 delay minutes reported on UA 1500.
Cancellations sit at 1.64% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
9.2% 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.
Every one of the 365 flights under UA 1500 in the data flew CID to DEN. 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. 365 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 1500
