Charlotte to Miami

What the Data Says About CLT to MIA

The Charlotte to Miami corridor (CLT → MIA) covers roughly 650 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 18,884 flights in the dataset, this route posts a 77.7% on-time rate with an average delay of 72.5 minutes when flights run late. Over the most recent 24 months of BTS data, 7,436 flights were recorded on this pairing — 93 cancelled (1.3%) and 23 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 18,884 total flights analyzed, the 77.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.5-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 88% on-time, while Jul 2024 came in at 63% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the CLT to MIA route, the combination of a 77.7% on-time rate, 72.5-minute average delay, 1.3% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
