Indianapolis to Boston

What the Data Says About IND to BOS

The Indianapolis to Boston corridor (IND → BOS) covers roughly 818 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 8,607 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 67.7 minutes when flights run late. Over the most recent 24 months of BTS data, 3,971 flights were recorded on this pairing — 46 cancelled (1.2%) and 5 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 8,607 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.7-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 93% on-time, while Sep 2025 came in at 62% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the IND to BOS route, the combination of a 83.7% on-time rate, 67.7-minute average delay, 1.2% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
