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 27 points, against half a point between the best and worst carrier.

- 8am–11am329 flights83.8%
- 11am–2pm20 flights—

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 57.0% on time, against 83.8% for the 8am–11am 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 8am–11am window is the busiest, with 329 flights scheduled in it.
Across the year
SkyWest on LBB to DEN through the year
February is the weak month at 65.4% on time, against 82.7% in March. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 78 flights.
Across the week, Friday is the strongest day at 75.0% on time and Monday the weakest at 66.7%, a spread of 8 points.

19 of 145 late departures made up the time and arrived on time, 13% of them. In the other direction, 68 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DEN.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 52% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 25%Late-arriving aircraft
- 21%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 9,978 of the 19,000 delay minutes reported here. The split is drawn from 19,060 reported delay minutes.
Cancellations sit at 1.57% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and stage length
What a delay here costs
11.9% 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 456 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 is a different operation and performs like one: it runs 75.8% on time across 700 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 701 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 LBB to DEN
Put together: treat all of this as provisional. 701 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 71.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 688 completed flights over 12 months sit behind that.
