Salt Lake City to Atlanta

What the Data Says About SLC to ATL

The Salt Lake City to Atlanta corridor (SLC → ATL) covers roughly 1,590 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 17,964 flights in the dataset, this route posts a 84.3% on-time rate with an average delay of 71.6 minutes when flights run late. Over the most recent 24 months of BTS data, 5,939 flights were recorded on this pairing — 32 cancelled (0.5%) and 13 diverted (0.2%). 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 17,964 total flights analyzed, the 84.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 71.6-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 2025 posted the best performance on this corridor at 92% on-time, while Jun 2025 came in at 73% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the SLC to ATL route, the combination of a 84.3% on-time rate, 71.6-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.
