Boise to Las Vegas

What the Data Says About BOI to LAS

The Boise to Las Vegas corridor (BOI → LAS) covers roughly 519 miles and is served by 23 carriers, based on Bureau of Transportation Statistics reporting. Across 7,482 flights in the dataset, this route posts a 82.1% on-time rate with an average delay of 70.0 minutes when flights run late. Over the most recent 24 months of BTS data, 3,130 flights were recorded on this pairing — 18 cancelled (0.6%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 23 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,482 total flights analyzed, the 82.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.0-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, Nov 2024 posted the best performance on this corridor at 92% on-time, while Sep 2025 came in at 74% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the BOI to LAS route, the combination of a 82.1% on-time rate, 70.0-minute average delay, 0.6% recent cancellation rate, and 23 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
