Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Delta Air Lines.
Delta on CVG to FLL lands a B+, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 525 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Delta on CVG to FLL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Delay causes
Why Delta runs late on this route
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 8,363 reported delay minutes.
- 39%Carrier
- 36%Late-arriving aircraft
- 18%National Airspace System
- 7%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,363 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 8,363 reported delay minutes.
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,256 of the 8,363 delay minutes reported here.
Cancellations sit at 0.95% against a national 1.89%, which is ordinary. Diversions add another 0.19%.
Connections and stage length
What a delay here costs
8.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
The 932 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 is a different operation and performs like one: it runs 71.8% on time across 525 flights, 7 points below 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 7 points of difference.
One caution: this is a thin sample. 525 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 Delta on CVG to FLL
Put together: treat all of this as provisional. 525 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 79.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 519 completed flights over 12 months sit behind that.
