What the Data Says About DTW to AZO

The Detroit to Kalamazoo corridor (DTW → AZO) covers roughly 113 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 5,926 flights in the dataset, this route posts a 86.1% on-time rate with an average delay of 92.3 minutes when flights run late. Over the most recent 24 months of BTS data, 2,008 flights were recorded on this pairing — 31 cancelled (1.5%) and 5 diverted (0.2%). 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 5,926 total flights analyzed, the 86.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.3-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, Oct 2025 posted the best performance on this corridor at 95% on-time, while Aug 2024 came in at 61% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the DTW to AZO route, the combination of a 86.1% on-time rate, 92.3-minute average delay, 1.5% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
