Pittsburgh to Boston

What the Data Says About PIT to BOS

The Pittsburgh to Boston corridor (PIT → BOS) covers roughly 496 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 10,671 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 77.4 minutes when flights run late. Over the most recent 24 months of BTS data, 4,422 flights were recorded on this pairing — 76 cancelled (1.7%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,671 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.4-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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Oct 2025 came in at 68% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the PIT to BOS route, the combination of a 83.7% on-time rate, 77.4-minute average delay, 1.7% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
