American on CLT to EYW lands a B, 3 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 a little over an hour on average. That rests on 927 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate American on CLT to EYW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 927 flights between September 2025 and August 2026. The median arrival is 8 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.

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 48% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 29%Carrier
- 16%National Airspace System
- 7%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 13,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 12,733 reported delay minutes.
Cancellations run at 2.70%, 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
7.4% 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.
The 736 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 80.3% on time across 927 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 927 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 American on CLT to EYW
Put together: treat all of this as provisional. 927 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 79.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 889 completed flights over 12 months sit behind that.
