Atlanta to Rochester

What the Data Says About ATL to ROC

The Atlanta to Rochester corridor (ATL → ROC) covers roughly 749 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 5,371 flights in the dataset, this route posts a 80.8% on-time rate with an average delay of 65.2 minutes when flights run late. Over the most recent 24 months of BTS data, 2,058 flights were recorded on this pairing — 29 cancelled (1.4%) and 4 diverted (0.2%). 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 5,371 total flights analyzed, the 80.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.2-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, Sep 2024 posted the best performance on this corridor at 91% on-time, while Dec 2025 came in at 57% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the ATL to ROC route, the combination of a 80.8% on-time rate, 65.2-minute average delay, 1.4% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
