Boston to Indianapolis

What the Data Says About BOS to IND

The Boston to Indianapolis corridor (BOS → IND) covers roughly 818 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 8,604 flights in the dataset, this route posts a 85.5% on-time rate with an average delay of 74.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,972 flights were recorded on this pairing — 52 cancelled (1.3%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,604 total flights analyzed, the 85.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.3-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 93% on-time, while May 2025 came in at 77% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the BOS to IND route, the combination of a 85.5% on-time rate, 74.3-minute average delay, 1.3% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
