What the Data Says About MHT to BWI

The Manchester to Baltimore corridor (MHT → BWI) covers roughly 377 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 9,047 flights in the dataset, this route posts a 88.8% on-time rate with an average delay of 61.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,171 flights were recorded on this pairing — 20 cancelled (0.6%) and 3 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 9,047 total flights analyzed, the 88.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.1-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 99% on-time, while Jul 2025 came in at 77% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the MHT to BWI route, the combination of a 88.8% on-time rate, 61.1-minute average delay, 0.6% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
