Frontier on CVG to FLL sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%.

When Frontier 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 193 flights.

Share of 188 completed flights by arrival against schedule.

5 of 37 late departures made up the time and arrived on time, 14% of them. In the other direction, 16 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 FLL.

The worst days

Worst days for Frontier on CVG to FLL

The latest arrival of the period was on 14 December 2025, 15 hours 39 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 55% of the 4,201 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
55%
National Airspace System
23%
Carrier
20%
Extreme weather
2%

55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,201 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 4,201 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 79.5% on time here.

Cancellations sit at 2.07% against a national 1.89%, which is ordinary. Diversions add another 0.52%.

Connections and stage length

What a delay here costs

11.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

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 64.6% on time across 193 flights, 10 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 10 points of difference.

One caution: this is a thin sample. 193 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 Frontier on CVG to FLL

Put together: treat all of this as provisional. 193 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 74.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 188 completed flights over 12 months sit behind that.
