Birmingham to Charlotte

What the Data Says About BHM to CLT

The Birmingham to Charlotte corridor (BHM → CLT) covers roughly 350 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 11,795 flights in the dataset, this route posts a 83.8% on-time rate with an average delay of 91.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,308 flights were recorded on this pairing — 78 cancelled (1.8%) and 5 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 11,795 total flights analyzed, the 83.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 91.0-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, Sep 2025 posted the best performance on this corridor at 91% on-time, while May 2024 came in at 65% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the BHM to CLT route, the combination of a 83.8% on-time rate, 91.0-minute average delay, 1.8% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
