Departure window
When American runs best on this route

Scale runs 50% to 70%. Rows with fewer than 30 flights show a dash.
The overnight block holds up unusually well at 63.4% on time across 298 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 298 flights scheduled in it.

|---|---|---|
| 21 July 2026 | 12 hours 58 minutes | Carrier |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 46% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 43%Carrier
- 8%National Airspace System
- 3%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 12,030 reported delay minutes.
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,168 of the 12,000 delay minutes reported here.
Cancellations sit at 1.05% against a national 1.89%, which is ordinary. Diversions add another 0.26%.
Connections and stage length
What a delay here costs
14.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 90.7% on time across 380 flights, 27 points above 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 MIA to MSP
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 63.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 375 completed flights over 12 months sit behind that.
