What the record says about this route
Which airline you fly changes the odds here. Southwest Airlines arrived on time 20 points more often than SkyWest Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
The season swings this route hard. In March it ran 20.8 points more punctual than in July — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
The route has been getting better. The later months in the record run 8.8 points more punctual than the earlier ones, which usually means a schedule that was too tight has been given more room.
This route does worse than its own airport. LBB as a whole runs 7.4 points more punctual than these flights, which points at something specific to the route — the time of day it is scheduled, or the aircraft that feed it — rather than the airport.
Which airline should you fly on this route?
Over January 2025 – August 2026, Southwest Airlines arrived on time most often on LBB to DEN. SkyWest Airlines was late most often. Flights ran closest to schedule in March and worst in July.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on LBB to DEN during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
