Atlanta to Bloomington/Normal

What the Data Says About ATL to BMI

The Atlanta to Bloomington/Normal corridor (ATL → BMI) covers roughly 533 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 3,738 flights in the dataset, this route posts a 87.1% on-time rate with an average delay of 100.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,459 flights were recorded on this pairing — 9 cancelled (0.6%) and 5 diverted (0.3%). 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 3,738 total flights analyzed, the 87.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 100.7-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, Oct 2024 posted the best performance on this corridor at 95% on-time, while Jul 2025 came in at 58% on-time — a 37-point gap between best and worst recent month. For travelers evaluating the ATL to BMI route, the combination of a 87.1% on-time rate, 100.7-minute average delay, 0.6% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
