Boston to Cincinnati

What the Data Says About BOS to CVG

The Boston to Cincinnati corridor (BOS → CVG) covers roughly 752 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 8,258 flights in the dataset, this route posts a 81.6% on-time rate with an average delay of 75.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,683 flights were recorded on this pairing — 53 cancelled (1.4%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 21 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,258 total flights analyzed, the 81.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.1-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, Mar 2024 posted the best performance on this corridor at 92% on-time, while Apr 2025 came in at 70% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the BOS to CVG route, the combination of a 81.6% on-time rate, 75.1-minute average delay, 1.4% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
