These figures cover 380 flights between September 2025 and August 2026. The median arrival is 17 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 380 flights.
There are not enough flights in each departure window to split American's MSP to MIA record by time of day without the percentages moving on noise. The headline rate of 90.7% is the reliable figure here.
Across the year
American on MSP to MIA through the year
October is the best month on the calendar at 100.0% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. August was the busiest month here, with 42 flights.
Across the week, Friday is the strongest day at 94.4% on time and Wednesday the weakest at 86.5%, a spread of 8 points.

Delay causes
Why American runs late on this route
Carrier accounts for 45% of the 4,187 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 44%Late-arriving aircraft
- 9%National Airspace System
- 2%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,187 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 4,187 reported delay minutes.
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,881 of the 4,187 delay minutes reported here.
Cancellations sit at 1.05% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 1,501 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 is a different operation and performs like one: it runs 63.7% on time across 380 flights, 27 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 27 points of difference.
One caution: this is a thin sample. 380 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 MSP to MIA
Put together: treat all of this as provisional. 380 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 90.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 376 completed flights over 12 months sit behind that.
