Dallas/Fort Worth to Miami

What the Data Says About DFW to MIA

The Dallas/Fort Worth to Miami corridor (DFW → MIA) covers roughly 1,121 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 24,505 flights in the dataset, this route posts a 73.3% on-time rate with an average delay of 74.4 minutes when flights run late. Over the most recent 24 months of BTS data, 9,829 flights were recorded on this pairing — 185 cancelled (1.9%) and 29 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 24,505 total flights analyzed, the 73.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.4-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, Feb 2024 posted the best performance on this corridor at 84% on-time, while Aug 2025 came in at 55% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the DFW to MIA route, the combination of a 73.3% on-time rate, 74.4-minute average delay, 1.9% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
