Kalispell to Salt Lake City

What the Data Says About FCA to SLC

The Kalispell to Salt Lake City corridor (FCA → SLC) covers roughly 531 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 6,989 flights in the dataset, this route posts a 91.6% on-time rate with an average delay of 105.4 minutes when flights run late. Over the most recent 24 months of BTS data, 2,305 flights were recorded on this pairing — 12 cancelled (0.5%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,989 total flights analyzed, the 91.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 105.4-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, Apr 2025 posted the best performance on this corridor at 99% on-time, while Jan 2024 came in at 74% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the FCA to SLC route, the combination of a 91.6% on-time rate, 105.4-minute average delay, 0.5% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
