Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on DEN to IDA 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 about an hour on average. That is a workable record, not a spotless one. That rests on 1,535 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on DEN to IDA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on DEN to IDA, 1,737 flights
These figures cover 1,535 flights between July 2025 and June 2026. The median arrival is 5 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 IDA
SkyWest flew 1,535 of the 1,737 flights on DEN to IDA, most of the route. Its 80.4% on time is about level with the route as a whole at 80.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 80.4% to Allegiant at 72.2%. Two 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 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 16 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–8am—
- 8am–11am361 flights88.0%
- 11am–2pm366 flights85.5%
- 2pm–5pm304 flights78.8%
- 5pm–8pm363 flights72.4%
- 8pm–5am141 flights71.9%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 88.0% of the time, against 71.9% for the overnight window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 366 flights scheduled in it.
Across the year
SkyWest on DEN to IDA through the year
July is the worst month at 67.2% on time, 23 points below November, the best at 90.1%. 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. July was the busiest month here, with 183 flights.
Across the week, Sunday is the strongest day at 82.9% on time and Thursday the weakest at 77.2%. 6 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 20,000 reported delay minutes.
- 42%Carrier
- 29%Late-arriving aircraft
- 21%National Airspace System
- 8%Extreme weather
The largest share of delay minutes, 42%, 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 8,329 of the 20,000 delay minutes reported here. The split is drawn from 20,013 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 88.0% on time here.
Cancellations are rare at 0.72%, 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
7.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 458 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 79.4% on time across 1,536 flights, within about 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 1,535 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 DEN to IDA
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 90.1% on time and July 67.2%, a swing of 23 points. If the dates move at all, move them out of July before you think about anything else. 1,519 completed flights over 12 months sit behind that.
