Bloomington/Normal to Atlanta

What the Data Says About BMI to ATL

The Bloomington/Normal to Atlanta corridor (BMI → ATL) covers roughly 533 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 3,737 flights in the dataset, this route posts a 87.7% on-time rate with an average delay of 99.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,459 flights were recorded on this pairing — 11 cancelled (0.8%) and 6 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,737 total flights analyzed, the 87.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.1-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, May 2023 posted the best performance on this corridor at 98% on-time, while Jan 2024 came in at 68% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the BMI to ATL route, the combination of a 87.7% on-time rate, 99.1-minute average delay, 0.8% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
