Oakland to Portland

What the Data Says About OAK to PDX

The Oakland to Portland corridor (OAK → PDX) covers roughly 543 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 10,931 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 56.6 minutes when flights run late. Over the most recent 24 months of BTS data, 3,154 flights were recorded on this pairing — 12 cancelled (0.4%) and 2 diverted (0.1%). 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 10,931 total flights analyzed, the 83.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.6-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, Aug 2024 posted the best performance on this corridor at 92% on-time, while Jul 2025 came in at 71% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the OAK to PDX route, the combination of a 83.3% on-time rate, 56.6-minute average delay, 0.4% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
