These figures cover 321 flights between September 2025 and August 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.

Across the year
UA 1547 quarter by quarter
UA 1547 did not run the same all year. Its best quarter was Jul–Sep 2026 at 88.0% on time and its weakest Oct–Dec 2025 at 71.6%, a swing of 16 points on roughly 80 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 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 87.8% on time and worst on Wednesday at 73.8%. Each day rests on about 46 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Share of 318 completed flights by arrival against schedule.
8 of 47 late departures made up the time and arrived on time, 17% of them. In the other direction, 19 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 FCA.
The worst days
Worst days for UA 1547
The latest arrival of the period was on 16 March 2026, 5 hours 2 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 |
|---|---|---|
| 16 March 2026 | 5 hours 2 minutes | Late-arriving aircraft |
| 19 December 2025 | 3 hours 31 minutes | Late-arriving aircraft |
| 20 December 2025 | 2 hours 17 minutes | Carrier |
| 28 May 2026 | 1 hour 52 minutes | Late-arriving aircraft |
| 12 June 2026 | 1 hour 49 minutes | Late-arriving aircraft |
Delay causes
Why UA 1547 runs late
Late-arriving aircraft accounts for 44% of the 2,795 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 33%Carrier
- 22%National Airspace System
- 1%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,795 reported delay minutes here, that single category outweighs weather by 32 to one. The split is drawn from 2,795 delay minutes reported on UA 1547.
Cancellations are rare at 0.62%, 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
Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 8.3% 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.
The same number turns up on six other city pairs in the data, including SDF to DEN (21), CVG to ORD (4) and DTW to ORD (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. 321 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 0.62% cancelled over 321 flights. Those are rates from the past twelve months, not a forecast for any particular day.
