Greensboro/High Point to Chicago

What the Data Says About GSO to ORD

The Greensboro/High Point to Chicago corridor (GSO → ORD) covers roughly 589 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 4,619 flights in the dataset, this route posts a 81.6% on-time rate with an average delay of 77.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,457 flights were recorded on this pairing — 31 cancelled (1.3%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,619 total flights analyzed, the 81.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.6-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, Aug 2025 posted the best performance on this corridor at 90% on-time, while Dec 2024 came in at 66% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the GSO to ORD route, the combination of a 81.6% on-time rate, 77.6-minute average delay, 1.3% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
