Boston to Charlotte

What the Data Says About BOS to CLT

The Boston to Charlotte corridor (BOS → CLT) covers roughly 728 miles and is served by 24 carriers, based on Bureau of Transportation Statistics reporting. Across 25,137 flights in the dataset, this route posts a 84.5% on-time rate with an average delay of 81.2 minutes when flights run late. Over the most recent 24 months of BTS data, 9,482 flights were recorded on this pairing — 156 cancelled (1.6%) and 8 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 24 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 25,137 total flights analyzed, the 84.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 81.2-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 90% on-time, while Sep 2025 came in at 72% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the BOS to CLT route, the combination of a 84.5% on-time rate, 81.2-minute average delay, 1.6% recent cancellation rate, and 24 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
