Carrier by carrier
PSA against every carrier on GSP to CLT
PSA flew 1,106 of the 1,538 flights on GSP to CLT, most of the route. Its 82.0% on time is about level with the route as a whole at 82.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from American at 85.6% to Envoy at 78.8%. Two 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.

Worst days for PSA on GSP to CLT
The latest arrival of the period was on 11 March 2026, 25 hours 56 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |

| 11 March 2026 | 25 hours 56 minutes | Late-arriving aircraft |
| 28 July 2026 | 17 hours 26 minutes | Extreme weather |

Delay causes
Why PSA runs late on this route
Late-arriving aircraft accounts for 48% of the 25,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 40%Carrier
- 9%Extreme weather
- 4%National Airspace System
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 25,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 24,998 reported delay minutes.
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 9,879 of the 25,000 delay minutes reported here.
Cancellations run at 2.71%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
10.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 64.9% on time across 1,108 flights, 17 points below 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 17 points of difference.
The sample behind these figures is 1,106 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking PSA on GSP to CLT
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 96.9% on time and July 65.2%, a swing of 32 points. If the dates move at all, move them out of July before you think about anything else. 1,075 completed flights over 12 months sit behind that.
