Boston to Atlanta

What the Data Says About BOS to ATL

The Boston to Atlanta corridor (BOS → ATL) covers roughly 946 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 26,632 flights in the dataset, this route posts a 82.5% on-time rate with an average delay of 75.0 minutes when flights run late. Over the most recent 24 months of BTS data, 10,018 flights were recorded on this pairing — 111 cancelled (1.1%) and 23 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 26,632 total flights analyzed, the 82.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.0-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 2024 came in at 70% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the BOS to ATL route, the combination of a 82.5% on-time rate, 75.0-minute average delay, 1.1% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
