Los Angeles to Boise

What the Data Says About LAX to BOI

The Los Angeles to Boise corridor (LAX → BOI) covers roughly 674 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 9,438 flights in the dataset, this route posts a 87.2% on-time rate with an average delay of 72.3 minutes when flights run late. Over the most recent 24 months of BTS data, 2,996 flights were recorded on this pairing — 4 cancelled (0.1%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,438 total flights analyzed, the 87.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.3-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, Sep 2025 posted the best performance on this corridor at 94% on-time, while Jul 2024 came in at 79% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the LAX to BOI route, the combination of a 87.2% on-time rate, 72.3-minute average delay, 0.1% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
