What the Data Says About CIU to DTW

The Sault Ste. Marie to Detroit corridor (CIU → DTW) covers roughly 284 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,530 flights in the dataset, this route posts a 84.5% on-time rate with an average delay of 130.4 minutes when flights run late. Over the most recent 24 months of BTS data, 734 flights were recorded on this pairing — 7 cancelled (1.0%) and 2 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,530 total flights analyzed, the 84.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 130.4-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the CIU to DTW route, the combination of a 84.5% on-time rate, 130.4-minute average delay, 1.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
