Atlanta to Boston

What the Data Says About ATL to BOS

The Atlanta to Boston corridor (ATL → BOS) covers roughly 946 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 26,645 flights in the dataset, this route posts a 81% on-time rate with an average delay of 67.8 minutes when flights run late. Over the most recent 24 months of BTS data, 10,019 flights were recorded on this pairing — 103 cancelled (1.0%) and 13 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 26,645 total flights analyzed, the 81% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.8-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, Feb 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 66% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the ATL to BOS route, the combination of a 81% on-time rate, 67.8-minute average delay, 1.0% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
