These figures cover 779 flights between September 2025 and August 2026. The median arrival is 17 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.

Departure window
When United runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 10 points, against half a point between the best and worst carrier.
- 5am–8am275 flights86.3%
- 8am–11am—
- 11am–2pm364 flights85.1%
- 2pm–5pm140 flights75.9%
- 5pm–8pm—
- 8pm–5am—
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 86.3% of the time, against 75.9% for the afternoon window. That is 10 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 364 flights scheduled in it.
Across the year
United on HDN to DEN through the year
February is the weak month at 66.3% on time, against 94.4% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 93 flights.
Across the week, Tuesday is the strongest day at 89.9% on time and Thursday the weakest at 79.8%, a spread of 10 points.

The latest arrival of the period was on 27 December 2025, 8 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as national airspace system delay.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 December 2025 | 8 hours 34 minutes | Late-arriving aircraft |
| 17 February 2026 | 5 hours 37 minutes | National Airspace System |
| 30 November 2025 | 5 hours 9 minutes | Late-arriving aircraft |

Delay causes
Why United runs late on this route
Late-arriving aircraft accounts for 47% of the 9,446 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 30%National Airspace System
- 23%Carrier
- 0%Extreme weather
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,446 reported delay minutes here, that single category outweighs weather by 47 to one. The split is drawn from 9,446 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 86.3% on time here.
Cancellations sit at 0.90% against a national 1.89%, which is ordinary. Diversions add another 0.13%.
Connections and stage length
What a delay here costs
6.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
At 141 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 71.9% on time across 780 flights, 12 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 12 points of difference.
One caution: this is a thin sample. 779 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 United on HDN to DEN
Put together: treat all of this as provisional. 779 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 83.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 771 completed flights over 12 months sit behind that.
