Monterey to Phoenix

What the Data Says About MRY to PHX

The Monterey to Phoenix corridor (MRY → PHX) covers roughly 598 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 6,744 flights in the dataset, this route posts a 85.1% on-time rate with an average delay of 97.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,817 flights were recorded on this pairing — 21 cancelled (0.7%) and 6 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,744 total flights analyzed, the 85.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 97.9-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, Jan 2024 posted the best performance on this corridor at 91% on-time, while Oct 2025 came in at 75% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the MRY to PHX route, the combination of a 85.1% on-time rate, 97.9-minute average delay, 0.7% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
