Greensboro/High Point to Detroit

What the Data Says About GSO to DTW

The Greensboro/High Point to Detroit corridor (GSO → DTW) covers roughly 460 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 1,284 flights in the dataset, this route posts a 88.2% on-time rate with an average delay of 103.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,284 flights were recorded on this pairing — 33 cancelled (2.6%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,284 total flights analyzed, the 88.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 103.8-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, Jul 2021 posted the best performance on this corridor at 97% on-time, while Jul 2025 came in at 71% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the GSO to DTW route, the combination of a 88.2% on-time rate, 103.8-minute average delay, 2.6% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
