Gulfport/Biloxi to Charlotte

What the Data Says About GPT to CLT

The Gulfport/Biloxi to Charlotte corridor (GPT → CLT) covers roughly 577 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 5,045 flights in the dataset, this route posts a 85.3% on-time rate with an average delay of 90.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,989 flights were recorded on this pairing — 52 cancelled (2.6%) and 5 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,045 total flights analyzed, the 85.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 90.2-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, Sep 2025 posted the best performance on this corridor at 97% on-time, while Sep 2024 came in at 71% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the GPT to CLT route, the combination of a 85.3% on-time rate, 90.2-minute average delay, 2.6% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
