Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1092, check with United Airlines.
UA 1092 lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That is a workable record, not a spotless one. That rests on 288 flights, with a median arrival 1 minute early.

These figures cover 288 flights between July 2025 and June 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.
Schedule
When UA 1092 flies
UA 1092 flies DEN to MSO without a single fixed slot. Its most common scheduled departure was 19:20, used on 79 of 288 flights, with 19:25 (57 flights) and 19:35 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1092 runs 10 points better at 78.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
UA 1092 next to DEN to MSO
Every carrier on DEN to MSO combined arrived on time 80.5% of the time across 1,214 flights, so UA 1092 is 3 points behind it. United flew 718 flights on the same city pair under all its flight numbers, including this one, and those ran 79.0% on time. Across its whole network United Airlines managed 79.0%, close to this flight's figure.

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 2025 at 66.7%, a swing of 15 points on roughly 72 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.

- Oct–Dec 202591 flights81.3%
- Jan–Mar 202669 flights79.7%
- Apr–Jun 202691 flights77.8%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1092 did best on Wednesday at 85.0% on time and worst on Sunday at 71.4%. Each day rests on about 41 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1092 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 3,449 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 49%Late-arriving aircraft
- 35%Carrier
- 16%National Airspace System
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,449 reported delay minutes here, that single category outweighs weather by 49 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,449 delay minutes reported on UA 1092.
Cancellations are rare at 0.00%, below the national 1.81% 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
5.9% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on five other city pairs in the data, including SYR to DEN (72), 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. 288 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 1092
For a booking, read UA 1092 as 78.0% on time with 0.00% cancelled over 288 flights. Those are rates from the past twelve months, not a forecast for any particular day.
