Delay causes
Why SkyWest runs late on this route
Carrier accounts for 68% of the 20,000 delay minutes carriers reported here, and the remaining four split what is left.
- 68%Carrier
- 13%Late-arriving aircraft
- 13%Extreme weather
- 6%National Airspace System
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 2.1 times the usual weather exposure. The split is drawn from 19,966 reported delay minutes.
The largest share of delay minutes, 68%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 20,000 delay minutes reported here.
Cancellations sit at 2.16% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and stage length
What a delay here costs
11.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 592 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.
The return leg is a different operation and performs like one: it runs 73.9% on time across 697 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 696 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 COS to DFW
Put together: treat all of this as provisional. 696 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 76.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 679 completed flights over 12 months sit behind that.
