Phoenix to Spokane

What the Data Says About PHX to GEG

The Phoenix to Spokane corridor (PHX → GEG) covers roughly 1,020 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 5,735 flights in the dataset, this route posts a 80.3% on-time rate with an average delay of 64.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,362 flights were recorded on this pairing — 2 cancelled (0.1%) 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 5,735 total flights analyzed, the 80.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.5-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 91% on-time, while Jul 2024 came in at 56% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the PHX to GEG route, the combination of a 80.3% on-time rate, 64.5-minute average delay, 0.1% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
