Greer to Dallas/Fort Worth

What the Data Says About GSP to DFW

The Greer to Dallas/Fort Worth corridor (GSP → DFW) 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 79.3% on-time rate with an average delay of 88.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,438 flights were recorded on this pairing — 40 cancelled (1.6%) and 14 diverted (0.6%). 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 79.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.6-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, Nov 2024 posted the best performance on this corridor at 89% on-time, while Jan 2024 came in at 60% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the GSP to DFW route, the combination of a 79.3% on-time rate, 88.6-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.
