American on CLT to PIT lands a B, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 1,760 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 American on CLT to PIT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,760 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
American against every carrier on CLT to PIT
American flew 1,760 of the 1,980 flights on CLT to PIT, most of the route. Its 77.5% on time is 2 points better than the route as a whole, which runs 75.8%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from American at 77.5% to PSA at 61.8%. 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 American runs best on this route

- 8am–11am237 flights88.8%

Book the early departure. Flights leaving between 5am–8am arrive on time 89.0% of the time, against 70.8% for the overnight window. That is 18 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 463 flights scheduled in it.
Across the year
American on CLT to PIT through the year
August is the worst month at 68.7% on time, 15 points below November, the best at 83.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 175 flights.
Across the week, Tuesday is the strongest day at 83.0% on time and Sunday the weakest at 72.0%, a spread of 11 points.

The worst days
Worst days for American on CLT to PIT
The latest arrival of the period was on 1 August 2026, 10 hours 46 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 August 2026 | 10 hours 46 minutes | Carrier |
| 4 April 2026 | 9 hours 25 minutes | Late-arriving aircraft |
| 12 June 2026 | 9 hours 12 minutes | Carrier |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 53% of the 26,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 36%Carrier
- 7%National Airspace System
- 4%Extreme weather
- 0%Security
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 26,078 reported delay minutes.
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 9,448 of the 26,000 delay minutes reported here.
Cancellations sit at 1.25% against a national 1.89%, which is ordinary. Diversions add another 0.11%.
Connections and stage length
What a delay here costs
7.7% 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 an hour, which a normal layover absorbs.
At 366 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 84.6% on time across 1,761 flights, 7 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 7 points of difference.
The sample behind these figures is 1,760 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 American on CLT to PIT
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 83.2% on time and August 68.7%, a swing of 15 points. If the dates move at all, move them out of August before you think about anything else. 1,736 completed flights over 12 months sit behind that.
