Newark to Greer

What the Data Says About EWR to GSP

The Newark to Greer corridor (EWR → GSP) covers roughly 594 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 3,314 flights in the dataset, this route posts a 82.9% on-time rate with an average delay of 73.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,851 flights were recorded on this pairing — 75 cancelled (4.1%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,314 total flights analyzed, the 82.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.2-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, Feb 2024 posted the best performance on this corridor at 98% on-time, while Jul 2025 came in at 69% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the EWR to GSP route, the combination of a 82.9% on-time rate, 73.2-minute average delay, 4.1% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
