Phoenix to Monterey

What the Data Says About PHX to MRY

The Phoenix to Monterey corridor (PHX → MRY) covers roughly 598 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 6,745 flights in the dataset, this route posts a 82% on-time rate with an average delay of 74.2 minutes when flights run late. Over the most recent 24 months of BTS data, 2,817 flights were recorded on this pairing — 15 cancelled (0.5%) and 23 diverted (0.8%). 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 6,745 total flights analyzed, the 82% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.2-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, Mar 2024 posted the best performance on this corridor at 96% on-time, while May 2025 came in at 64% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the PHX to MRY route, the combination of a 82% on-time rate, 74.2-minute average delay, 0.5% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
