The 5pm–8pm window is where this operation falls apart: 52.7% on time, against 89.5% for the 5am–8am slot.

Across the week, Wednesday is the strongest day at 79.4% on time and Friday the weakest at 54.2%, a spread of 25 points.
Carrier by carrier
Which airlines ran best at CLT in August
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 81.1% of the time; PSA Airlines manages 62.9%. Sample sizes sit next to every figure, because a two-point gap across 3,335 flights means less than a ten-point one.

PSA Airlines cancels 3.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held CLT up in August
Late-arriving aircraft accounts for 48% of the 404,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 26%Carrier
- 17%National Airspace System
- 9%Extreme weather
- 0%Security
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 404,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 404,290 reported delay minutes.
Cancellations sit at 1.57% against a national 1.86%, which is ordinary. Diversions add another 0.43%.
14.2% of arrivals land a full hour or more behind schedule, against 10.9% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from CLT in August
For a August trip through CLT: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 89.5% on time, and with 14.2% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
