What the Data Says About PHX to HOU

The Phoenix to Houston corridor (PHX → HOU) covers roughly 1,020 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 11,056 flights in the dataset, this route posts a 79.7% on-time rate with an average delay of 52.9 minutes when flights run late. Over the most recent 24 months of BTS data, 4,230 flights were recorded on this pairing — 32 cancelled (0.8%) and 17 diverted (0.4%). 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 11,056 total flights analyzed, the 79.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 52.9-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 2025 posted the best performance on this corridor at 89% on-time, while Jul 2025 came in at 63% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the PHX to HOU route, the combination of a 79.7% on-time rate, 52.9-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
