Portland to Oakland

What the Data Says About PDX to OAK

The Portland to Oakland corridor (PDX → OAK) covers roughly 543 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 10,764 flights in the dataset, this route posts a 85.6% on-time rate with an average delay of 57.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,118 flights were recorded on this pairing — 19 cancelled (0.6%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 13 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 10,764 total flights analyzed, the 85.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.3-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 94% on-time, while Jul 2025 came in at 61% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the PDX to OAK route, the combination of a 85.6% on-time rate, 57.3-minute average delay, 0.6% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
