Departure window
The best time of day to leave MIA in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,157 flights90.8%
- 8am–11am1,264 flights86.4%
- 11am–2pm1,146 flights75.6%
- 2pm–5pm1,588 flights71.4%
- 5pm–8pm1,950 flights70.7%
- 8pm–5am2,165 flights74.5%
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 70.7% for the evening window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 2,165 flights scheduled in it.
Across the week, Tuesday is the strongest day at 86.2% on time and Sunday the weakest at 65.7%. 21 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at MIA in November
The choice of carrier is not cosmetic here. Envoy Air arrives on time 85.9% of the time; Delta Air Lines manages 74.9%. Sample sizes sit next to every figure, because a two-point gap across 940 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| American Airlines | 5,258 | 75.1% | 63 min | 1.46% | B |

Delay causes
What held MIA up in November
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 139,000 reported delay minutes.
- 36%Carrier
- 35%Late-arriving aircraft
- 28%National Airspace System
- 1%Extreme weather
- 0%Security
35% 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 139,000 reported delay minutes here, that single category outweighs weather by 30 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 139,218 reported delay minutes.
Cancellations sit at 1.95% against a national 2.49%, which is ordinary. Diversions add another 0.20%.
7.7% of arrivals land an hour or more late, close to the national 7.8%. 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 about an hour, which a normal layover absorbs.
