| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 August 2026 | 5 hours 33 minutes | Late-arriving aircraft |
| 24 June 2026 | 4 hours 57 minutes | Late-arriving aircraft |

Delay causes
Why UA 719 runs late
Late-arriving aircraft accounts for 66% of the 8,296 delay minutes carriers reported here, and the remaining four split what is left.
- 66%Late-arriving aircraft
- 25%Carrier
- 9%National Airspace System
- 1%Extreme weather
66% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,296 reported delay minutes here, that single category outweighs weather by 66 to one. The split is drawn from 8,296 delay minutes reported on UA 719.
Cancellations are rare at 0.27%, 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
12.7% 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 804 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 SJC to DEN (34) and RNO to EWR (1), but none flew often enough under UA 719 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RNO 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 719
For a booking, UA 719 is a flight to put a long connection behind. 12.7% 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.
