Dallas/Fort Worth to Greer

What the Data Says About DFW to GSP

The Dallas/Fort Worth to Greer corridor (DFW → GSP) covers roughly 862 miles and is served by 19 carriers, based on Bureau of Transportation Statistics reporting. Across 5,828 flights in the dataset, this route posts a 74.8% on-time rate with an average delay of 76.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,437 flights were recorded on this pairing — 38 cancelled (1.6%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 19 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,828 total flights analyzed, the 74.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.6-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 2024 posted the best performance on this corridor at 82% on-time, while Jun 2025 came in at 48% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the DFW to GSP route, the combination of a 74.8% on-time rate, 76.6-minute average delay, 1.6% recent cancellation rate, and 19 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
