Houston to Phoenix

What the Data Says About HOU to PHX

The Houston to Phoenix corridor (HOU → PHX) covers roughly 1,020 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 11,069 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 56.6 minutes when flights run late. Over the most recent 24 months of BTS data, 4,263 flights were recorded on this pairing — 37 cancelled (0.9%) and 4 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 11,069 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.6-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, Sep 2024 posted the best performance on this corridor at 94% on-time, while May 2024 came in at 66% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the HOU to PHX route, the combination of a 80.6% on-time rate, 56.6-minute average delay, 0.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
