Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with United Airlines.
United on DEN to OMA lands a B+, about a point better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 1,285 flights. The strongest carrier on the route with a full sample, SkyWest Airlines, flew 424 at 88.4% on time.
The US average over the same twelve months is 77.3%, so there is little to separate United on DEN to OMA 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 OMA
United flew 1,285 of the 3,326 flights on DEN to OMA, about 39% of it. Its 78.1% on time is about level with the route as a whole at 76.9%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from SkyWest at 88.4% to Frontier at 69.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 88.4% of the time; Southwest Airlines manages 73.6%. Sample sizes sit next to every figure, because a two-point gap across 1,385 flights means less than a ten-point one.

| SkyWest Airlines | 424 | 88.4% | 56 min | 0.71% | A+ |
| United Airlines (this page) | 1,285 | 78.1% | 67 min | 0.23% | B+ |

The spread between SkyWest and Southwest is 15 points, wide enough that it should decide the booking. On a hundred trips that is 15 more arrivals inside the on-time window.

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 20 points, against 15 points between the best and worst carrier.
- 5am–8am—
- 8am–11am344 flights86.9%
- 11am–2pm220 flights87.7%
- 2pm–5pm143 flights72.0%
- 5pm–8pm363 flights72.1%
- 8pm–5am215 flights68.1%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 87.7% on time, ahead of 8pm–5am at 68.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 363 flights scheduled in it.
Across the year
United on DEN to OMA through the year

Across the week, Tuesday is the strongest day at 82.4% on time and Sunday the weakest at 75.4%, a spread of 7 points.

The latest arrival of the period was on 3 August 2026, 5 hours 34 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 |
|---|---|---|
| 3 August 2026 | 5 hours 34 minutes | Late-arriving aircraft |
| 23 July 2026 | 5 hours 5 minutes | Late-arriving aircraft |
| 30 July 2026 | 4 hours 53 minutes | Carrier |

Delay causes
Why United runs late on this route
Late-arriving aircraft accounts for 53% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 30%Carrier
- 16%National Airspace System
- 2%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 19,000 reported delay minutes here, that single category outweighs weather by 33 to one. The split is drawn from 18,690 reported delay minutes.
Cancellations are rare at 0.23%, 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
8.5% 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 about an hour, which a normal layover absorbs.
At 472 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 11am–2pm window matters as much as it does.
The return leg runs 78.2% on time across 1,284 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,285 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking United on DEN to OMA
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 90.0% on time and August 64.2%, a swing of 26 points. If the dates move at all, move them out of August before you think about anything else. 1,281 completed flights over 12 months sit behind that.
