Tucson to Phoenix

What the Data Says About TUS to PHX

The Tucson to Phoenix corridor (TUS → PHX) covers roughly 110 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 14,273 flights in the dataset, this route posts a 85.1% on-time rate with an average delay of 87.8 minutes when flights run late. Over the most recent 24 months of BTS data, 6,593 flights were recorded on this pairing — 29 cancelled (0.4%) and 2 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 14,273 total flights analyzed, the 85.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 87.8-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, Apr 2025 posted the best performance on this corridor at 92% on-time, while Mar 2025 came in at 79% on-time — a 13-point gap between best and worst recent month. For travelers evaluating the TUS to PHX route, the combination of a 85.1% on-time rate, 87.8-minute average delay, 0.4% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
