What the Data Says About GEG to PDX

The Spokane to Portland corridor (GEG → PDX) covers roughly 279 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 3,909 flights in the dataset, this route posts a 88.1% on-time rate with an average delay of 65.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,403 flights were recorded on this pairing — 15 cancelled (1.1%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,909 total flights analyzed, the 88.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.7-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, Nov 2025 posted the best performance on this corridor at 95% on-time, while May 2025 came in at 81% on-time — a 14-point gap between best and worst recent month. For travelers evaluating the GEG to PDX route, the combination of a 88.1% on-time rate, 65.7-minute average delay, 1.1% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
