What the record says about this route
The two directions do not behave alike. FCA to LAS arrives on time 15.4 points less often than the outbound.

This route does better than its own airport. Departures from LAS overall run 11.2 points less punctual than this particular one — so whatever congestion LAS has, this route is largely escaping it.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on LAS to FCA during July 2024 – July 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 →
