Minneapolis to Spokane

What the Data Says About MSP to GEG

The Minneapolis to Spokane corridor (MSP → GEG) covers roughly 1,175 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 4,292 flights in the dataset, this route posts a 82.3% on-time rate with an average delay of 57.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,583 flights were recorded on this pairing — 8 cancelled (0.5%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,292 total flights analyzed, the 82.3% 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, Sep 2024 posted the best performance on this corridor at 98% on-time, while Dec 2025 came in at 58% on-time — a 41-point gap between best and worst recent month. For travelers evaluating the MSP to GEG route, the combination of a 82.3% on-time rate, 57.3-minute average delay, 0.5% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
