Miami to Charlotte

What the Data Says About MIA to CLT

The Miami to Charlotte corridor (MIA → CLT) covers roughly 650 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 18,889 flights in the dataset, this route posts a 78.9% on-time rate with an average delay of 77.3 minutes when flights run late. Over the most recent 24 months of BTS data, 7,445 flights were recorded on this pairing — 92 cancelled (1.2%) and 12 diverted (0.2%). 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 18,889 total flights analyzed, the 78.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.3-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 91% on-time, while Aug 2024 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the MIA to CLT route, the combination of a 78.9% on-time rate, 77.3-minute average delay, 1.2% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
