Atlanta to Salt Lake City

What the Data Says About ATL to SLC

The Atlanta to Salt Lake City corridor (ATL → SLC) covers roughly 1,590 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 17,947 flights in the dataset, this route posts a 83.3% on-time rate with an average delay of 58.6 minutes when flights run late. Over the most recent 24 months of BTS data, 5,928 flights were recorded on this pairing — 30 cancelled (0.5%) and 7 diverted (0.1%). 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 17,947 total flights analyzed, the 83.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.6-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, Nov 2024 posted the best performance on this corridor at 92% on-time, while Jul 2024 came in at 70% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the ATL to SLC route, the combination of a 83.3% on-time rate, 58.6-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.
