Detroit to Greensboro/High Point

What the Data Says About DTW to GSO

The Detroit to Greensboro/High Point corridor (DTW → GSO) covers roughly 460 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 1,281 flights in the dataset, this route posts a 86.6% on-time rate with an average delay of 91.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,281 flights were recorded on this pairing — 34 cancelled (2.7%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,281 total flights analyzed, the 86.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 91.5-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, Mar 2020 posted the best performance on this corridor at 99% on-time, while Jun 2021 came in at 71% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the DTW to GSO route, the combination of a 86.6% on-time rate, 91.5-minute average delay, 2.7% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
