What the Data Says About BWI to BDL

The Baltimore to Hartford corridor (BWI → BDL) covers roughly 283 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 9,086 flights in the dataset, this route posts a 75.1% on-time rate with an average delay of 54.8 minutes when flights run late. Over the most recent 24 months of BTS data, 3,425 flights were recorded on this pairing — 31 cancelled (0.9%) 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 9,086 total flights analyzed, the 75.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.8-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, Sep 2025 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 56% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the BWI to BDL route, the combination of a 75.1% on-time rate, 54.8-minute average delay, 0.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
