Boise to Los Angeles

What the Data Says About BOI to LAX

The Boise to Los Angeles corridor (BOI → LAX) covers roughly 674 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 9,537 flights in the dataset, this route posts a 89.2% on-time rate with an average delay of 73.7 minutes when flights run late. Over the most recent 24 months of BTS data, 3,004 flights were recorded on this pairing — 7 cancelled (0.2%) and 2 diverted (0.1%). 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 9,537 total flights analyzed, the 89.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.7-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, Jan 2025 posted the best performance on this corridor at 98% on-time, while Feb 2025 came in at 82% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the BOI to LAX route, the combination of a 89.2% on-time rate, 73.7-minute average delay, 0.2% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
