Boston to Los Angeles

What the Data Says About BOS to LAX

The Boston to Los Angeles corridor (BOS → LAX) covers roughly 2,611 miles and is served by 26 carriers, based on Bureau of Transportation Statistics reporting. Across 24,177 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 83.4 minutes when flights run late. Over the most recent 24 months of BTS data, 9,211 flights were recorded on this pairing — 39 cancelled (0.4%) and 10 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 26 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 24,177 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 83.4-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 88% on-time, while Feb 2025 came in at 62% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the BOS to LAX route, the combination of a 80.4% on-time rate, 83.4-minute average delay, 0.4% recent cancellation rate, and 26 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
