Los Angeles to Portland

What the Data Says About LAX to PDX

The Los Angeles to Portland corridor (LAX → PDX) covers roughly 834 miles and is served by 29 carriers, based on Bureau of Transportation Statistics reporting. Across 25,109 flights in the dataset, this route posts a 86.5% on-time rate with an average delay of 67.1 minutes when flights run late. Over the most recent 24 months of BTS data, 8,958 flights were recorded on this pairing — 87 cancelled (1.0%) and 3 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 29 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 25,109 total flights analyzed, the 86.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.1-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, Oct 2024 posted the best performance on this corridor at 94% on-time, while Jun 2025 came in at 80% on-time — a 14-point gap between best and worst recent month. For travelers evaluating the LAX to PDX route, the combination of a 86.5% on-time rate, 67.1-minute average delay, 1.0% recent cancellation rate, and 29 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
