Las Vegas to Boise

What the Data Says About LAS to BOI

The Las Vegas to Boise corridor (LAS → BOI) covers roughly 519 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 7,512 flights in the dataset, this route posts a 75.7% on-time rate with an average delay of 59.2 minutes when flights run late. Over the most recent 24 months of BTS data, 3,134 flights were recorded on this pairing — 13 cancelled (0.4%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 22 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,512 total flights analyzed, the 75.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 59.2-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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Jul 2024 came in at 68% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the LAS to BOI route, the combination of a 75.7% on-time rate, 59.2-minute average delay, 0.4% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
