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 6,416 reported delay minutes.
- 41%National Airspace System
- 31%Carrier
- 27%Late-arriving aircraft
- 1%Extreme weather
41% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,639 minutes out of 6,416, against a national NAS share of 21%. The split is drawn from 6,416 reported delay minutes.
Cancellations sit at 1.61% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
15.5% 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.
At 451 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 8pm–5am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 43.2% on time across 248 flights, 20 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 20 points of difference.
One caution: this is a thin sample. 249 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 SFO to EUG
Put together: treat all of this as provisional. 249 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 62.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 245 completed flights over 12 months sit behind that.
