Across 2,743 flights in the dataset, this route posts a 93.3% on-time rate with an average delay of 106.0 minutes when flights run late.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,743 total flights analyzed, the 93.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 106.0-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 2021 posted the best performance on this corridor at 100% on-time, while Dec 2021 came in at 78% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the GJT to SLC route, the combination of a 93.3% on-time rate, 106.0-minute average delay, 0.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
