Every carrier on LBB to DEN, 980 flights
These figures cover 708 flights between July 2025 and June 2026. Beyond the headline rate, 13.5% 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.
Carrier by carrier
SkyWest against every carrier on LBB to DEN
SkyWest flew 708 of the 980 flights on LBB to DEN, most of the route. Its 69.9% on time is 6 points worse than the route as a whole, which runs 75.5%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Southwest at 89.9% to SkyWest at 69.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 31 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–8am37 flights82.4%
- 8am–11am329 flights83.8%
- 11am–2pm20 flights—
- 2pm–5pm—
- 5pm–8pm322 flights52.9%
- 8pm–5am—
Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 52.9% 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
August is the worst month at 57.1% on time, 26 points below March, the best at 82.7%. 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. March was the busiest month here, with 78 flights.
Across the week, Sunday is the strongest day at 74.0% on time and Monday the weakest at 63.2%. 11 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 51% of the 20,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 51%Carrier
- 26%National Airspace System
- 21%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 51%, 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 10,000 of the 20,000 delay minutes reported here. The split is drawn from 20,312 reported delay minutes.
Cancellations sit at 1.55% against a national 1.81%, which is ordinary. Diversions add another 0.85%.
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. 13.5% 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 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 73.7% on time across 707 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. 708 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. 708 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 69.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 691 completed flights over 12 months sit behind that.
