Every carrier on DEN to EUG, 1,272 flights

These figures cover 116 flights between July 2025 and June 2026. The median arrival is 10 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 DEN to EUG

SkyWest flew 116 of the 1,272 flights on DEN to EUG, about 9% of it. Its 95.7% on time is 22 points better than the route as a whole, which runs 73.5%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 95.7% to Southwest at 69.8%.

The two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Departure window

When SkyWest 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 116 flights.

There are not enough flights in each departure window to split SkyWest's DEN to EUG record by time of day without the percentages moving on noise. The headline rate of 95.7% is the reliable figure here.

Across the year

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 95.7% on time across 116 flights.

Split by quarter, SkyWest on DEN to EUG logged 92 flights in Jul–Sep 2025 and 24 flights in Oct–Dec 2025. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 95.7% annual figure is the one to use.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 72% of the 299 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.

72% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 299 reported delay minutes here, that single category outweighs weather by 72 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 299 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 0.9% 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.

The 996 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 67.5% on time across 116 flights, 28 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 28 points of difference.

One caution: this is a thin sample. 116 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 DEN to EUG

Put together: treat all of this as provisional. 116 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 95.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 116 completed flights over 12 months sit behind that.
