Boston to Pittsburgh

What the Data Says About BOS to PIT

The Boston to Pittsburgh corridor (BOS → PIT) covers roughly 496 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 10,668 flights in the dataset, this route posts a 82.6% on-time rate with an average delay of 73.7 minutes when flights run late. Over the most recent 24 months of BTS data, 4,421 flights were recorded on this pairing — 66 cancelled (1.5%) 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 10,668 total flights analyzed, the 82.6% 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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Jan 2024 came in at 70% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the BOS to PIT route, the combination of a 82.6% on-time rate, 73.7-minute average delay, 1.5% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
