Los Angeles to Boston

What the Data Says About LAX to BOS

The Los Angeles to Boston corridor (LAX → BOS) covers roughly 2,611 miles and is served by 28 carriers, based on Bureau of Transportation Statistics reporting. Across 24,183 flights in the dataset, this route posts a 82.7% on-time rate with an average delay of 74.2 minutes when flights run late. Over the most recent 24 months of BTS data, 9,216 flights were recorded on this pairing — 37 cancelled (0.4%) and 21 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 28 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 24,183 total flights analyzed, the 82.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.2-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, Nov 2024 posted the best performance on this corridor at 90% on-time, while Oct 2025 came in at 72% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the LAX to BOS route, the combination of a 82.7% on-time rate, 74.2-minute average delay, 0.4% recent cancellation rate, and 28 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
