Dallas to Phoenix

What the Data Says About DAL to PHX

The Dallas to Phoenix corridor (DAL → PHX) covers roughly 879 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 16,232 flights in the dataset, this route posts a 79.2% on-time rate with an average delay of 58.9 minutes when flights run late. Over the most recent 24 months of BTS data, 6,065 flights were recorded on this pairing — 100 cancelled (1.6%) and 7 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 16,232 total flights analyzed, the 79.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.9-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 91% on-time, while May 2024 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the DAL to PHX route, the combination of a 79.2% on-time rate, 58.9-minute average delay, 1.6% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
