What the Data Says About BDL to IAD

The Hartford to Washington corridor (BDL → IAD) covers roughly 325 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 5,209 flights in the dataset, this route posts a 87.8% on-time rate with an average delay of 88.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,587 flights were recorded on this pairing — 14 cancelled (0.9%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,209 total flights analyzed, the 87.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.4-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, Jan 2025 posted the best performance on this corridor at 97% on-time, while Apr 2025 came in at 70% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the BDL to IAD route, the combination of a 87.8% on-time rate, 88.4-minute average delay, 0.9% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
