Atlanta to Hartford

What the Data Says About ATL to BDL

The Atlanta to Hartford corridor (ATL → BDL) covers roughly 859 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 11,785 flights in the dataset, this route posts a 84.3% on-time rate with an average delay of 62.7 minutes when flights run late. Over the most recent 24 months of BTS data, 4,430 flights were recorded on this pairing — 42 cancelled (0.9%) and 6 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 11,785 total flights analyzed, the 84.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.7-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 2025 posted the best performance on this corridor at 93% on-time, while Jul 2025 came in at 59% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the ATL to BDL route, the combination of a 84.3% on-time rate, 62.7-minute average delay, 0.9% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
