American on EYW to CLT 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 close to two hours on average. That rests on 927 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate American on EYW to CLT 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 11 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 EYW to CLT
American flew 927 of the 1,251 flights on EYW to CLT, most of the route. Its 80.3% on time is 2 points worse than the route as a whole, which runs 82.2%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Envoy at 87.4% to American at 80.3%. 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.

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 50% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 43%Carrier
- 4%Extreme weather
- 2%National Airspace System
- 0%Security
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 19,000 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 18,636 reported delay minutes.
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,954 of the 19,000 delay minutes reported here.
Cancellations run at 2.91%, against 1.89% nationally. That is roughly one flight in 30 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
7.6% 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 close to two hours, 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 79.9% 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 EYW to CLT
Put together: the delay figures matter less here than the 2.91% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 899 completed flights over 12 months sit behind that.
