These figures cover 456 flights between September 2025 and August 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 CLE to MIA
American flew 456 of the 892 flights on CLE to MIA, most of the route. Its 86.6% on time is 7 points better than the route as a whole, which runs 79.7%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from American at 86.6% to Republic at 25.0%. Three 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 21 points, against half a point between the best and worst carrier.
- 5am–8am365 flights90.8%
- 8am–11am—
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm91 flights69.7%
- 8pm–5am—
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.8% of the time, against 69.7% for the evening window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 365 flights scheduled in it.
Across the year
American on CLE to MIA through the year
January is the weak month at 74.5% on time, against 96.8% in July. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 62 flights.
Across the week, Saturday is the strongest day at 93.8% on time and Sunday the weakest at 78.1%, a spread of 16 points.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 January 2026 | 29 hours 2 minutes | Carrier |
| 26 March 2026 | 22 hours 15 minutes | Late-arriving aircraft |

Delay causes
Why American runs late on this route
Carrier accounts for 56% of the 7,946 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 32%Late-arriving aircraft
- 10%National Airspace System
- 1%Security
- 1%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,458 of the 7,946 delay minutes reported here. The split is drawn from 7,946 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.8% on time here.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.44%.
Connections and stage length
What a delay here costs
5.1% 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 about 2.2 hours, which a normal layover absorbs.
The 1,080 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 is a different operation and performs like one: it runs 69.9% on time across 456 flights, 17 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 17 points of difference.
One caution: this is a thin sample. 456 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 CLE to MIA
Put together: treat all of this as provisional. 456 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 86.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 449 completed flights over 12 months sit behind that.
