Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1547, check with United Airlines.

UA 1547 lands a B+, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 333 flights, with a median arrival 3 minutes early.

Set against the rest of the country, UA 1547's record is 4 points better than the US average of 77.6%. That gap is worth roughly 42 fewer late arrivals for every thousand flights.

These figures cover 333 flights between July 2025 and June 2026. The median arrival is 3 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When UA 1547 flies

UA 1547 is scheduled to leave Denver (DEN) at 11:15 local time and reach Kalispell (FCA) at 13:36. That slot held for 333 of the 333 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 11:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1547 runs 3 points better at 81.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 1547 next to DEN to FCA

United flew 848 flights on the same city pair under all its flight numbers, including this one, and those ran 79.3% on time. Across its whole network United Airlines managed 79.0%, which this flight beats by 3 points.

Across the year

UA 1547 quarter by quarter

UA 1547 did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.5% on time and its weakest Oct–Dec 2025 at 71.6%, a swing of 18 points on roughly 83 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.

Jul–Sep 202586 flights89.5%
Oct–Dec 202567 flights71.6%
Jan–Mar 202689 flights78.2%
Apr–Jun 202691 flights85.6%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1547 did best on Monday at 89.6% on time and worst on Wednesday at 73.9%. Each day rests on about 48 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1547 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,813 reported delay minutes.

Late-arriving aircraft
39%
Carrier
38%
National Airspace System
22%
Extreme weather
1%

39% 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 2,813 reported delay minutes here, that single category outweighs weather by 29 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 2,813 delay minutes reported on UA 1547.

Cancellations are rare at 0.60%, below the national 1.81% 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

Badly late arrivals are rare here: only 3.9% 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 752 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 CVG to ORD (4), DTW to ORD (1) and ORD to CVG (1), but none flew often enough under UA 1547 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to FCA only.

One caution: this is a thin sample. 333 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 1547

For a booking, read UA 1547 as 81.8% on time with 0.60% cancelled over 333 flights. Those are rates from the past twelve months, not a forecast for any particular day.
