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

SkyWest on DEN to GJT lands a B, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 1,550 flights, with a median arrival 8 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on DEN to GJT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.4% of the time, against 69.7% for the afternoon window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.

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.

  • Carrier
    41%
  • Late-arriving aircraft
    36%
  • National Airspace System
    15%
  • Extreme weather
    5%
  • Security
    4%

36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 20,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 20,337 reported delay minutes.

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 8,255 of the 20,000 delay minutes reported here.

Cancellations sit at 1.87% against a national 1.89%, which is ordinary. Diversions add another 0.06%.

Connections and stage length

What a delay here costs

7.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

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 77.0% on time across 1,550 flights, 4 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 4 points of difference.

The sample behind these figures is 1,550 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 GJT

Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 92.7% on time and August 69.9%, a swing of 23 points. If the dates move at all, move them out of August before you think about anything else. 1,520 completed flights over 12 months sit behind that.
