What the Data Says About BWI to MHT

The Baltimore to Manchester corridor (BWI → MHT) covers roughly 377 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 9,060 flights in the dataset, this route posts a 78.3% on-time rate with an average delay of 53.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,196 flights were recorded on this pairing — 21 cancelled (0.7%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,060 total flights analyzed, the 78.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 53.3-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 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 61% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the BWI to MHT route, the combination of a 78.3% on-time rate, 53.3-minute average delay, 0.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
