Share of 290 completed flights by arrival against schedule.
9 of 67 late departures made up the time and arrived on time, 13% of them. In the other direction, 15 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at RIC.
The worst days
Worst days for UA 1534
The latest arrival of the period was on 9 November 2025, 5 hours 21 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 5 hours 21 minutes | Late-arriving aircraft |
| 6 March 2026 | 4 hours 23 minutes | Carrier |
| 29 July 2026 | 3 hours 55 minutes | Late-arriving aircraft |
| 17 February 2026 | 3 hours 52 minutes | Late-arriving aircraft |

Delay causes
Why UA 1534 runs late
Late-arriving aircraft accounts for 57% of the 5,249 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 27%Carrier
- 15%National Airspace System
- 1%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,249 reported delay minutes here, that single category outweighs weather by 49 to one. The split is drawn from 5,249 delay minutes reported on UA 1534.
Cancellations are rare at 0.34%, 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
11.7% 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 1,481 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 three other city pairs in the data, including RNO to DEN (164), GJT to DEN (36) and SNA to DEN (21), but none flew often enough under UA 1534 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to RIC only.
One caution: this is a thin sample. 291 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 1534
For a booking, read UA 1534 as 74.8% on time with 0.34% cancelled over 291 flights. Those are rates from the past twelve months, not a forecast for any particular day.
