Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with United Airlines.
United on XNA to DEN lands a B+, 3 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 370 flights, with a median arrival 2 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate United on XNA to DEN from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 370 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.

Carrier by carrier
United against every carrier on XNA to DEN
United flew 370 of the 1,345 flights on XNA to DEN, about 28% of it. Its 80.7% on time is about level with the route as a whole at 81.5%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Frontier at 82.0% to United at 80.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When United runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 370 flights.
There are not enough flights in each departure window to split United's XNA to DEN record by time of day without the percentages moving on noise. The headline rate of 80.7% is the reliable figure here.
Across the year
United on XNA to DEN through the year
June is the worst month at 63.6% on time, 26 points below April, the best at 90.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. June was the busiest month here, with 33 flights.
Across the week, Tuesday is the strongest day at 86.8% on time and Sunday the weakest at 73.6%, a spread of 13 points.

Share of 368 completed flights by arrival against schedule.
12 of 55 late departures made up the time and arrived on time, 22% of them. In the other direction, 28 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 DEN.
The worst days
Worst days for United on XNA to DEN
The latest arrival of the period was on 19 June 2026, 8 hours 58 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 June 2026 | 8 hours 58 minutes | Carrier |
| 10 October 2025 | 5 hours 59 minutes | Late-arriving aircraft |
| 29 July 2026 | 3 hours 7 minutes | Carrier |
| 25 January 2026 | 2 hours 57 minutes | National Airspace System |

Delay causes
Why United runs late on this route
Carrier accounts for 58% of the 4,851 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 29%National Airspace System
- 7%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,825 of the 4,851 delay minutes reported here. The split is drawn from 4,851 reported delay minutes.
Cancellations are rare at 0.54%, 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 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.
The 616 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 return leg is a different operation and performs like one: it runs 75.9% on time across 370 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 370 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 XNA to DEN
Put together: treat all of this as provisional. 370 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 80.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 368 completed flights over 12 months sit behind that.
