Dallas/Fort Worth to Harlingen/San Benito

What the Data Says About DFW to HRL

The Dallas/Fort Worth to Harlingen/San Benito corridor (DFW → HRL) covers roughly 461 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 7,762 flights in the dataset, this route posts a 84.2% on-time rate with an average delay of 65.6 minutes when flights run late. Over the most recent 24 months of BTS data, 3,252 flights were recorded on this pairing — 96 cancelled (3.0%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,762 total flights analyzed, the 84.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.6-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 93% on-time, while May 2024 came in at 68% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the DFW to HRL route, the combination of a 84.2% on-time rate, 65.6-minute average delay, 3.0% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
