Dallas to Houston

What the Data Says About DAL to HOU

The Dallas to Houston corridor (DAL → HOU) covers roughly 239 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 23,563 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 59.6 minutes when flights run late. Over the most recent 24 months of BTS data, 8,214 flights were recorded on this pairing — 185 cancelled (2.3%) and 20 diverted (0.2%). 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 23,563 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 59.6-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, Feb 2024 posted the best performance on this corridor at 90% on-time, while May 2024 came in at 58% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the DAL to HOU route, the combination of a 80.6% on-time rate, 59.6-minute average delay, 2.3% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
