Miami to Dallas/Fort Worth

What the Data Says About MIA to DFW

The Miami to Dallas/Fort Worth corridor (MIA → DFW) covers roughly 1,121 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 24,449 flights in the dataset, this route posts a 74.3% on-time rate with an average delay of 79.8 minutes when flights run late. Over the most recent 24 months of BTS data, 9,818 flights were recorded on this pairing — 182 cancelled (1.9%) and 53 diverted (0.5%). 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 24,449 total flights analyzed, the 74.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.8-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 87% on-time, while Mar 2024 came in at 59% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the MIA to DFW route, the combination of a 74.3% on-time rate, 79.8-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.
