Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with American Airlines.

American on SLC to CLT lands a B+, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 556 flights, with a median arrival 15 minutes early.

Set against the rest of the country, American's SLC to CLT record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

Every carrier on SLC to CLT, 921 flights

These figures cover 556 flights between July 2025 and June 2026. The median arrival is 15 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 SLC to CLT

American flew 556 of the 921 flights on SLC to CLT, most of the route. Its 82.5% on time is 2 points worse than the route as a whole, which runs 84.3%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Delta at 87.0% to American at 82.5%.

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 14 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am37 flights81.8%
11am–2pm173 flights81.5%
2pm–5pm65 flights71.9%
5pm–8pm—
8pm–5am281 flights85.7%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

The overnight block holds up unusually well at 85.7% on time across 281 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 281 flights scheduled in it.

Across the year

American on SLC to CLT through the year

Darker means more delays. Figures are on-time percentages.September best, June worst

June is the worst month at 71.9% on time, 18 points below September, the best at 90.3%. 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. March was the busiest month here, with 62 flights.

Across the week, Monday is the strongest day at 87.2% on time and Sunday the weakest at 75.0%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why American runs late on this route

One category carries most of the weight here. Carrier accounts for 52% of the 8,541 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.

Extreme weather
1%

40% 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 8,541 reported delay minutes here, that single category outweighs weather by 40 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 8,541 reported delay minutes.

The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 4,463 of the 8,541 delay minutes reported here.

Cancellations sit at 0.90% against a national 1.81%, which is ordinary. Diversions add another 0.36%.

Connections and stage length

What a delay here costs

5.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

At 1,727 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg runs 80.2% on time across 556 flights, within 2 points 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. 556 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 SLC to CLT

Put together: treat all of this as provisional. 556 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 82.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 549 completed flights over 12 months sit behind that.
