Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with American Airlines.
American on CLT to BWI lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 1,780 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate American on CLT to BWI from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
American against every carrier on CLT to BWI
American flew 1,780 of the 2,947 flights on CLT to BWI, most of the route. Its 76.4% on time is about level with the route as a whole at 76.9%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from Envoy at 100.0% to Frontier at 76.4%. Three 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.

That is 27 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 586 flights scheduled in it.

The worst days
Worst days for American on CLT to BWI
The latest arrival of the period was on 12 June 2026, 14 hours 53 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across June, May, August and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 June 2026 | 14 hours 53 minutes | Late-arriving aircraft |
| 27 May 2026 | 9 hours 11 minutes | Late-arriving aircraft |
| 11 August 2026 | 9 hours 3 minutes | Extreme weather |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 50% of the 30,000 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 29%Carrier
- 12%National Airspace System
- 9%Extreme weather
- 0%Security
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 30,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 30,468 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 95.5% on time here.
Cancellations sit at 1.52% against a national 1.89%, which is ordinary. Diversions add another 0.11%.
Connections and stage length
What a delay here costs
8.6% 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 a little over an hour, which a normal layover absorbs.
At 361 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 1,780 flights, 8 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 8 points of difference.
The sample behind these figures is 1,780 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 BWI
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 89.0% on time and July 59.6%, a swing of 29 points. If the dates move at all, move them out of July before you think about anything else. 1,751 completed flights over 12 months sit behind that.
