These figures cover 108 flights between September 2025 and August 2026. The median arrival is 11 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
Envoy against every carrier on DTW to MIA
Envoy flew 108 of the 1,757 flights on DTW to MIA, about 6% of it. Its 81.5% on time is about level with the route as a whole at 80.7%. Ranked by on-time rate it is number two of six carriers on the route, where the range runs from American at 88.9% to Frontier at 66.7%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. American Airlines arrives on time 88.9% of the time; Delta Air Lines manages 79.1%. Sample sizes sit next to every figure, because a two-point gap across 929 flights means less than a ten-point one.

American leads Delta by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Departure window
When Envoy 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 108 flights.
There are not enough flights in each departure window to split Envoy's DTW to MIA record by time of day without the percentages moving on noise. The headline rate of 81.5% is the reliable figure here.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 81.5% on time across 108 flights.
Split by quarter, Envoy on DTW to MIA logged 8 flights in Oct–Dec 2025, 45 flights in Jan–Mar 2026, 34 flights in Apr–Jun 2026 and 21 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 81.5% annual figure is the one to use.

The latest arrival of the period was on 18 March 2026, 6 hours 54 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 March 2026 | 6 hours 54 minutes | Late-arriving aircraft |
| 1 July 2026 | 2 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 79% of the 1,437 delay minutes carriers reported here, and the remaining four split what is left.
- 79%Late-arriving aircraft
- 15%National Airspace System
- 3%Extreme weather
- 3%Carrier
79% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,437 reported delay minutes here, that single category outweighs weather by 27 to one. The split is drawn from 1,437 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.6% 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.
The 1,145 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 runs 82.4% on time across 108 flights, within about a point 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. 108 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 Envoy on DTW to MIA
Put together: treat all of this as provisional. 108 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 81.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 108 completed flights over 12 months sit behind that.
