Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Envoy Air.
Envoy on GSP to CLT lands a B, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 55 minutes on average. That rests on 153 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on GSP to CLT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on GSP to CLT, 1,538 flights
These figures cover 153 flights between September 2025 and August 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Envoy against every carrier on GSP to CLT
Envoy flew 153 of the 1,538 flights on GSP to CLT, about 10% of it. Its 78.8% on time is 4 points worse than the route as a whole, which runs 82.3%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from American at 85.6% to Envoy at 78.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Envoy runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm98 flights85.7%
- 2pm–5pm—
- 5pm–8pm55 flights66.0%
- 8pm–5am—
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 85.7% on time, ahead of 5pm–8pm at 66.0%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 98 flights scheduled in it.

Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 78.8% annual figure is the one to use.

The worst days
Worst days for Envoy on GSP to CLT
The latest arrival of the period was on 2 August 2026, 4 hours 35 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 August 2026 | 4 hours 35 minutes | Late-arriving aircraft |
| 20 February 2026 | 3 hours 13 minutes | Late-arriving aircraft |
| 16 March 2026 | 2 hours 24 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 72% of the 1,741 delay minutes carriers reported here, and the remaining four split what is left.
- 72%Late-arriving aircraft
- 13%Carrier
- 9%National Airspace System
- 6%Extreme weather
72% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,741 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 1,741 reported delay minutes.
Cancellations sit at 1.31% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
5.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, which a normal layover absorbs.
At 75 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 84.1% on time across 152 flights, 5 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
One caution: this is a thin sample. 153 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Envoy on GSP to CLT
Put together: treat all of this as provisional. 153 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 78.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 151 completed flights over 12 months sit behind that.
