These figures cover 336 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
UA 1092 quarter by quarter
UA 1092 did not run the same all year. Its best quarter was Oct–Dec 2025 at 81.3% on time and its weakest Jul–Sep 2026 at 53.3%, a swing of 28 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1092 did best on Tuesday at 83.3% on time and worst on Monday at 65.3%. Each day rests on about 48 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The worst days
Worst days for UA 1092
The latest arrival of the period was on 26 September 2025, 3 hours 10 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 |
|---|---|---|
| 26 September 2025 | 3 hours 10 minutes | Late-arriving aircraft |
| 24 August 2026 | 3 hours 8 minutes | Late-arriving aircraft |
| 28 July 2026 | 3 hours 6 minutes | Carrier |
| 10 August 2026 | 2 hours 56 minutes | Late-arriving aircraft |

Delay causes
Why UA 1092 runs late
Late-arriving aircraft accounts for 51% of the 4,765 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 34%Carrier
- 15%National Airspace System
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,765 reported delay minutes here, that single category outweighs weather by 51 to one. The split is drawn from 4,765 delay minutes reported on UA 1092.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 679 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 six other city pairs in the data, including PIT to DEN (46), PHX to DEN (40) and LAS to DEN (29), but none flew often enough under UA 1092 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MSO only.
One caution: this is a thin sample. 336 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.
