Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with United Airlines.
United on DEN to XNA sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, about a point worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 370 flights, with a median arrival 3 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate United on DEN to XNA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
United against every carrier on DEN to XNA
United flew 370 of the 1,346 flights on DEN to XNA, about 27% of it. Its 75.9% on time is 6 points worse than the route as a whole, which runs 82.0%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from SkyWest at 84.5% to United at 75.9%. 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 DEN to XNA record by time of day without the percentages moving on noise. The headline rate of 75.9% is the reliable figure here.
Across the year
United on DEN to XNA through the year
November is the best month on the calendar at 90.6% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. June was the busiest month here, with 33 flights.
Across the week, Monday is the strongest day at 85.2% on time and Thursday the weakest at 70.6%, a spread of 15 points.

Share of 369 completed flights by arrival against schedule.
10 of 73 late departures made up the time and arrived on time, 14% of them. In the other direction, 26 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 XNA.
The worst days
Worst days for United on DEN to XNA
The latest arrival of the period was on 14 August 2026, 7 hours 1 minute behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 August 2026 | 7 hours 1 minute | Late-arriving aircraft |
| 28 July 2026 | 4 hours 30 minutes | Late-arriving aircraft |
| 21 June 2026 | 4 hours 18 minutes | Late-arriving aircraft |
| 13 August 2026 | 3 hours 52 minutes | Late-arriving aircraft |

Delay causes
Why United runs late on this route
Late-arriving aircraft accounts for 51% of the 6,617 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 28%Carrier
- 18%National Airspace System
- 2%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,617 reported delay minutes here, that single category outweighs weather by 25 to one. The split is drawn from 6,617 reported delay minutes.
Cancellations are rare at 0.27%, 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
10.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 80.7% on time across 370 flights, 5 points above 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 DEN to XNA
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 75.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 369 completed flights over 12 months sit behind that.
