Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1347, check with United Airlines.
UA 1347 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 315 flights, with a median arrival 1 minute early.

These figures cover 315 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 1347 flies
UA 1347 flies DEN to BZN without a single fixed slot. Its most common scheduled departure was 19:50, used on 71 of 315 flights, with 19:45 (69 flights) and 19:20 (48 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 19:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1347 runs 12 points better at 80.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 1347 quarter by quarter
Quarter by quarter UA 1347 held fairly steady: 74.4% in Jul–Sep 2025, 79.1% in Oct–Dec 2025, 82.2% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202591 flights79.1%
- Jan–Mar 202690 flights82.2%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, UA 1347 did best on Monday at 88.9% on time and worst on Sunday at 75.6%. Each day rests on about 45 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1347 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 3,002 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.
- 56%Late-arriving aircraft
- 28%Carrier
- 14%National Airspace System
- 2%Extreme weather
56% 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 3,002 reported delay minutes here, that single category outweighs weather by 25 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 3,002 delay minutes reported on UA 1347.
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
Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 524 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 three other city pairs in the data, including DEN to OMA (31), ORD to FLL (18) and DCA to ORD (18), but none flew often enough under UA 1347 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BZN only.
One caution: this is a thin sample. 315 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 1347
For a booking, read UA 1347 as 80.6% on time with 0.00% cancelled over 315 flights. Those are rates from the past twelve months, not a forecast for any particular day.
