Cleveland to Boston

What the Data Says About CLE to BOS

The Cleveland to Boston corridor (CLE → BOS) covers roughly 563 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 8,891 flights in the dataset, this route posts a 83.1% on-time rate with an average delay of 78.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,481 flights were recorded on this pairing — 45 cancelled (1.3%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,891 total flights analyzed, the 83.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.1-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, Apr 2025 posted the best performance on this corridor at 95% on-time, while Dec 2025 came in at 69% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the CLE to BOS route, the combination of a 83.1% on-time rate, 78.1-minute average delay, 1.3% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
