Buffalo to Charlotte

What the Data Says About BUF to CLT

The Buffalo to Charlotte corridor (BUF → CLT) covers roughly 546 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 6,416 flights in the dataset, this route posts a 81.5% on-time rate with an average delay of 105.1 minutes when flights run late. Over the most recent 24 months of BTS data, 2,482 flights were recorded on this pairing — 42 cancelled (1.7%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,416 total flights analyzed, the 81.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 105.1-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, Oct 2024 posted the best performance on this corridor at 90% on-time, while Jul 2024 came in at 58% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the BUF to CLT route, the combination of a 81.5% on-time rate, 105.1-minute average delay, 1.7% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
