Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on GJT to DEN sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 1,496 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on GJT 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 1,496 flights between July 2025 and June 2026. Beyond the headline rate, 9.4% 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.

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 23 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–8am327 flights87.8%
- 8am–11am81 flights86.2%
- 11am–2pm364 flights82.6%
- 2pm–5pm362 flights65.3%
- 5pm–8pm362 flights64.6%
- 8pm–5am—
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 64.6% on time, against 87.8% for the 5am–8am 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 364 flights scheduled in it.
Across the year
SkyWest on GJT to DEN through the year
August is the worst month at 52.9% on time, 35 points below November, the best at 88.2%. 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 152 flights.
Across the week, Wednesday is the strongest day at 79.2% on time and Monday the weakest at 69.8%. 9 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 28,000 reported delay minutes.
- 38%Carrier
- 28%National Airspace System
- 23%Late-arriving aircraft
- 10%Extreme weather
- 0%Security
The largest share of delay minutes, 38%, 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 11,000 of the 28,000 delay minutes reported here. The split is drawn from 27,738 reported delay minutes.
Cancellations sit at 2.01% against a national 1.81%, which is ordinary. Diversions add another 0.20%.
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. 9.4% 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 212 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 80.5% on time across 1,496 flights, 5 points above 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 5 points of difference.
The sample behind these figures is 1,496 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 GJT to DEN
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 88.2% on time and August 52.9%, a swing of 35 points. If the dates move at all, move them out of August before you think about anything else. 1,463 completed flights over 12 months sit behind that.
