Ithaca/Cortland to Detroit

What the Data Says About ITH to DTW

The Ithaca/Cortland to Detroit corridor (ITH → DTW) covers roughly 353 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 1,125 flights in the dataset, this route posts a 91.2% on-time rate with an average delay of 118.1 minutes when flights run late. Over the most recent 24 months of BTS data, 735 flights were recorded on this pairing — 3 cancelled (0.4%) and 0 diverted (0.0%). 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 1,125 total flights analyzed, the 91.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 118.1-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 ITH to DTW route, the combination of a 91.2% on-time rate, 118.1-minute average delay, 0.4% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
