These figures cover 795 flights between September 2025 and August 2026. The median arrival is 7 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.

Share of 789 completed flights by arrival against schedule.
31 of 119 late departures made up the time and arrived on time, 26% of them. In the other direction, 40 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 MIA.
The worst days
Worst days for Envoy on CVG to MIA
The latest arrival of the period was on 29 March 2026, 4 hours 40 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 March 2026 | 4 hours 40 minutes | Carrier |
| 3 August 2026 | 4 hours 7 minutes | Carrier |
| 27 July 2026 | 3 hours 40 minutes | Late-arriving aircraft |

Delay causes
Why Envoy runs late on this route
Carrier accounts for 47% of the 6,840 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 27%Late-arriving aircraft
- 23%National Airspace System
- 3%Extreme weather
- 0%Security
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,216 of the 6,840 delay minutes reported here. The split is drawn from 6,840 reported delay minutes.
Cancellations are rare at 0.63%, 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 3.9% 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 83.5% on time across 805 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. 795 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 CVG to MIA
Put together: treat all of this as provisional. 795 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 83.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 789 completed flights over 12 months sit behind that.
