These figures cover 805 flights between September 2025 and August 2026. The median arrival is 9 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 Envoy runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 19 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am104 flights96.2%
- 11am–2pm—
- 2pm–5pm139 flights77.5%
- 5pm–8pm291 flights83.0%
- 8pm–5am271 flights82.2%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 96.2% of the time, against 77.5% for the afternoon window. That is 19 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 291 flights scheduled in it.
Across the year
Envoy on MIA to CVG through the year
July is the worst month at 75.8% on time, 17 points below June, the best at 93.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 86 flights.
Across the week, Tuesday is the strongest day at 88.7% on time and Sunday the weakest at 77.2%, a spread of 12 points.

Share of 799 completed flights by arrival against schedule.
21 of 101 late departures made up the time and arrived on time, 21% of them. In the other direction, 52 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CVG.
The worst days
Worst days for Envoy on MIA to CVG
The latest arrival of the period was on 27 April 2026, 3 hours 27 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 April 2026 | 3 hours 27 minutes | Late-arriving aircraft |
| 8 September 2025 | 2 hours 52 minutes | Late-arriving aircraft |
| 15 March 2026 | 2 hours 16 minutes | National Airspace System |
| 6 February 2026 | 2 hours 13 minutes | Late-arriving aircraft |
| 15 January 2026 | 2 hours 12 minutes | Late-arriving aircraft |
Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 45% of the 5,752 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 31%National Airspace System
- 18%Carrier
- 5%Extreme weather
- 0%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,752 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 5,752 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 96.2% on time here.
Cancellations are rare at 0.62%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is 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 3.3% 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 948 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 83.8% on time across 795 flights, within half 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. 805 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 MIA to CVG
Put together: treat all of this as provisional. 805 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 83.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 799 completed flights over 12 months sit behind that.
