These figures cover 536 flights between September 2025 and August 2026. The median arrival is 14 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.

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.

- 8am–11am38 flights82.4%
- 11am–2pm178 flights80.6%
- 2pm–5pm65 flights71.9%
- 5pm–8pm—
- 8pm–5am255 flights86.3%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
The overnight block holds up unusually well at 86.3% on time across 255 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 255 flights scheduled in it.
Across the year
American on SLC to CLT through the year
August is the worst month at 69.7% on time, 21 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 87.0% on time and Saturday the weakest at 73.9%, a spread of 13 points.

Delay causes
Why American runs late on this route
Carrier accounts for 50% of the 8,392 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 43%Late-arriving aircraft
- 7%National Airspace System
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,392 reported delay minutes here, that single category outweighs weather by 43 to one. The split is drawn from 8,392 reported delay minutes.
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,203 of the 8,392 delay minutes reported here.
Cancellations sit at 0.93% against a national 1.89%, which is ordinary. Diversions add another 0.56%.
Connections and stage length
What a delay here costs
5.9% 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 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 80.9% on time across 536 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. 536 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. 536 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 82.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 528 completed flights over 12 months sit behind that.
