SkyWest on OMA to DEN earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%.

Set against the rest of the country, SkyWest's OMA to DEN record is 12 points better than the US average of 77.6%. That gap is worth roughly 119 fewer late arrivals for every thousand flights.

Every carrier on OMA to DEN, 3,289 flights

These figures cover 386 flights between July 2025 and June 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.

Carrier by carrier

SkyWest against every carrier on OMA to DEN

SkyWest flew 386 of the 3,289 flights on OMA to DEN, about 12% of it. Its 89.5% on time is 13 points better than the route as a whole, which runs 76.1%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from SkyWest at 89.5% to Frontier at 69.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. United Airlines arrives on time 78.4% of the time; Southwest Airlines manages 71.3%. Sample sizes sit next to every figure, because a two-point gap across 1,404 flights means less than a ten-point one.

On-time performance by carrier on OMA to DEN
Airline	Flights	On time	Avg delay	Cancelled	Grade
SkyWest Airlines (this page)	386	89.5%	90 min	0.78%	A+

United leads Southwest by 7 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Departure window

When SkyWest runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 37 points, against 7 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 58.1% on time, against 95.0% for the 11am–2pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 183 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 89.5% on time across 386 flights.

SkyWest on OMA to DEN did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.6% on time and its weakest Apr–Jun 2026 at 82.1%, a swing of 16 points on roughly 97 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.

Across the week, Friday is the strongest day at 95.2% on time and Monday the weakest at 78.7%. 17 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 47% of the 3,596 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,702 of the 3,596 delay minutes reported here. The split is drawn from 3,596 reported delay minutes.

Cancellations are rare at 0.78%, below the national 1.81% 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

Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 8.1% 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.

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 89.0% on time across 385 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.

One caution: this is a thin sample. 386 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 SkyWest on OMA to DEN

Put together: treat all of this as provisional. 386 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 89.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 381 completed flights over 12 months sit behind that.
