Oakland to Phoenix

What the Data Says About OAK to PHX

The Oakland to Phoenix corridor (OAK → PHX) covers roughly 646 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 12,403 flights in the dataset, this route posts a 83.1% on-time rate with an average delay of 56.8 minutes when flights run late. Over the most recent 24 months of BTS data, 4,033 flights were recorded on this pairing — 8 cancelled (0.2%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 12,403 total flights analyzed, the 83.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.8-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, Mar 2025 posted the best performance on this corridor at 91% on-time, while Dec 2025 came in at 70% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the OAK to PHX route, the combination of a 83.1% on-time rate, 56.8-minute average delay, 0.2% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
