Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.
American on TYS to CLT sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land about 2.1 hours behind schedule. That rests on 193 flights, with a median arrival 1 minute early.

These figures cover 193 flights between July 2025 and June 2026. Beyond the headline rate, 12.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
American against every carrier on TYS to CLT
American flew 193 of the 867 flights on TYS to CLT, about 22% of it. Its 71.9% on time is 7 points worse than the route as a whole, which runs 79.0%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Envoy at 92.3% to SkyWest at 65.0%. Two 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
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am24 flights—
- 8am–11am34 flights82.4%
- 11am–2pm18 flights—
- 2pm–5pm1 flights—
- 5pm–8pm52 flights69.2%
- 8pm–5am64 flights58.7%
Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 58.7% on time, against 82.4% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8pm–5am window is the busiest, with 64 flights scheduled in it.
Across the year

Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 71.9% on time across 193 flights.
Split by quarter, American on TYS to CLT logged 130 flights in Jul–Sep 2025 and 63 flights in Oct–Dec 2025. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 71.9% annual figure is the one to use.
Delay causes
Why American runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 73% of the 6,769 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 73%Late-arriving aircraft
- 18%Carrier
- 5%National Airspace System
- 4%Extreme weather
73% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,769 reported delay minutes here, that single category outweighs weather by 20 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,769 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 82.4% on time here.
Cancellations are rare at 0.52%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 176 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 8am–11am window matters as much as it does.
The return leg runs 70.8% on time across 193 flights, within about 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. 193 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 TYS to CLT
Put together: treat all of this as provisional. 193 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 71.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 192 completed flights over 12 months sit behind that.
