Elmira/Corning to Detroit

What the Data Says About ELM to DTW

The Elmira/Corning to Detroit corridor (ELM → DTW) covers roughly 332 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 4,715 flights in the dataset, this route posts a 87.3% on-time rate with an average delay of 114.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,566 flights were recorded on this pairing — 10 cancelled (0.6%) 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 4,715 total flights analyzed, the 87.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 114.5-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).

Looking at recent months, Sep 2025 posted the best performance on this corridor at 97% on-time, while Jan 2024 came in at 58% on-time — a 39-point gap between best and worst recent month. For travelers evaluating the ELM to DTW route, the combination of a 87.3% on-time rate, 114.5-minute average delay, 0.6% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
