Detroit to Ithaca/Cortland

What the Data Says About DTW to ITH

The Detroit to Ithaca/Cortland corridor (DTW → ITH) covers roughly 353 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 1,124 flights in the dataset, this route posts a 90.3% on-time rate with an average delay of 63.5 minutes when flights run late. Over the most recent 24 months of BTS data, 735 flights were recorded on this pairing — 1 cancelled (0.1%) and 3 diverted (0.4%). 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 1,124 total flights analyzed, the 90.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.5-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 DTW to ITH route, the combination of a 90.3% on-time rate, 63.5-minute average delay, 0.1% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
