Houston to Harlingen/San Benito

What the Data Says About HOU to HRL

The Houston to Harlingen/San Benito corridor (HOU → HRL) covers roughly 277 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 7,441 flights in the dataset, this route posts a 80% on-time rate with an average delay of 54.4 minutes when flights run late. Over the most recent 24 months of BTS data, 2,657 flights were recorded on this pairing — 33 cancelled (1.2%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,441 total flights analyzed, the 80% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.4-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, Jan 2025 posted the best performance on this corridor at 95% on-time, while Jul 2024 came in at 63% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the HOU to HRL route, the combination of a 80% on-time rate, 54.4-minute average delay, 1.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
