Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.

SkyWest on DRO to DEN lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 1,461 flights, with a median arrival 11 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on DRO 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 1,461 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

SkyWest against every carrier on DRO to DEN

SkyWest flew 1,461 of the 2,192 flights on DRO to DEN, most of the route. Its 80.1% on time is about level with the route as a whole at 81.2%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from United at 83.3% to SkyWest at 80.1%.

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 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 21 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am223 flights89.7%
8am–11am194 flights92.7%
11am–2pm318 flights83.7%
2pm–5pm364 flights72.1%
5pm–8pm362 flights71.9%
8pm–5am—

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 92.7% of the time, against 71.9% for the evening window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 364 flights scheduled in it.

Across the year

SkyWest on DRO to DEN through the year

Darker means more delays. Figures are on-time percentages.January best, July worst

July is the worst month at 64.4% on time, 24 points below January, the best at 88.8%. 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. May was the busiest month here, with 143 flights.

Across the week, Sunday is the strongest day at 82.6% on time and Friday the weakest at 77.6%. 5 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 27,000 reported delay minutes.

Late-arriving aircraft
34%
Carrier
29%
National Airspace System
25%
Extreme weather
13%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 26,735 reported delay minutes.

34% 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 27,000 reported delay minutes here, that single category outweighs weather by 3 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.

Cancellations sit at 1.57% against a national 1.81%, which is ordinary. Diversions add another 0.07%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 251 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 8am–11am window matters as much as it does.

The return leg runs 82.0% on time across 1,460 flights, within 2 points 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 1,461 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 SkyWest on DRO to DEN

Put together: the calendar is the biggest lever here, not the carrier or the hour. January runs 88.8% on time and July 64.4%, a swing of 24 points. If the dates move at all, move them out of July before you think about anything else. 1,437 completed flights over 12 months sit behind that.
