Salt Lake City to Grand Junction

What the Data Says About SLC to GJT

The Salt Lake City to Grand Junction corridor (SLC → GJT) covers roughly 216 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,741 flights in the dataset, this route posts a 91.6% on-time rate with an average delay of 89.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,772 flights were recorded on this pairing — 4 cancelled (0.2%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,741 total flights analyzed, the 91.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.0-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 2025 posted the best performance on this corridor at 100% on-time, while Jul 2021 came in at 77% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the SLC to GJT route, the combination of a 91.6% on-time rate, 89.0-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.
