These figures cover 309 flights between September 2025 and August 2026. The median arrival is 2 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 1772 quarter by quarter
UA 1772 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.9% on time and its weakest Jan–Mar 2026 at 73.9%, a swing of 14 points on roughly 77 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.

- Apr–Jun 202691 flights81.3%

By weekday, UA 1772 did best on Saturday at 90.9% on time and worst on Friday at 71.4%. Each day rests on about 44 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

6 of 47 late departures made up the time and arrived on time, 13% of them. In the other direction, 18 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 MTJ.
The worst days
Worst days for UA 1772
The latest arrival of the period was on 19 December 2025, 6 hours 11 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, January, March and February, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 December 2025 | 6 hours 11 minutes | Carrier |
| 4 January 2026 | 2 hours 50 minutes | Carrier |
| 6 March 2026 | 2 hours 49 minutes | National Airspace System |

Delay causes
Why UA 1772 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 3,518 reported delay minutes.
- 38%Carrier
- 32%Late-arriving aircraft
- 30%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,322 of the 3,518 delay minutes reported here. The split is drawn from 3,518 delay minutes reported on UA 1772.
Cancellations are rare at 0.32%, 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 4.9% 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 same number turns up on four other city pairs in the data, including SFO to ONT (55), RDU to DEN (19) and OKC to DEN (16), but none flew often enough under UA 1772 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to MTJ only.
One caution: this is a thin sample. 309 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 1772
For a booking, read UA 1772 as 80.8% on time with 0.32% cancelled over 309 flights. Those are rates from the past twelve months, not a forecast for any particular day.
