Los Angeles to Phoenix

What the Data Says About LAX to PHX

The Los Angeles to Phoenix corridor (LAX → PHX) covers roughly 370 miles and is served by 34 carriers, based on Bureau of Transportation Statistics reporting. Across 40,246 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 67.8 minutes when flights run late. Over the most recent 24 months of BTS data, 14,804 flights were recorded on this pairing — 88 cancelled (0.6%) and 10 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 34 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 40,246 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.8-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, Jan 2025 posted the best performance on this corridor at 90% on-time, while May 2024 came in at 68% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the LAX to PHX route, the combination of a 83.7% on-time rate, 67.8-minute average delay, 0.6% recent cancellation rate, and 34 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
