Denver to Las Vegas

What the Data Says About DEN to LAS

The Denver to Las Vegas corridor (DEN → LAS) covers roughly 628 miles and is served by 27 carriers, based on Bureau of Transportation Statistics reporting. Across 44,636 flights in the dataset, this route posts a 76.1% on-time rate with an average delay of 65.3 minutes when flights run late. Over the most recent 24 months of BTS data, 15,425 flights were recorded on this pairing — 126 cancelled (0.8%) and 11 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 27 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 44,636 total flights analyzed, the 76.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.3-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Dec 2024 posted the best performance on this corridor at 86% on-time, while Jul 2025 came in at 63% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the DEN to LAS route, the combination of a 76.1% on-time rate, 65.3-minute average delay, 0.8% recent cancellation rate, and 27 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
