Frontier on CVG to FLL sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 196 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Frontier on CVG to FLL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 196 flights between July 2025 and June 2026. Beyond the headline rate, 10.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Frontier against every carrier on CVG to FLL
Frontier flew 196 of the 987 flights on CVG to FLL, about 20% of it. Its 75.9% on time is about level with the route as a whole at 76.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 78.3% to Allegiant at 72.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
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 196 flights.
- 5am–8am40 flights79.5%
- 8am–11am29 flights—
- 11am–2pm35 flights79.4%
- 2pm–5pm79 flights74.4%
- 5pm–8pm13 flights—
- 8pm–5am—
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 79.5% on time for the 5am–8am window against 74.4% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 2pm–5pm window is the busiest, with 79 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 75.9% on time across 196 flights.
Frontier on CVG to FLL did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.9% on time and its weakest Jan–Mar 2026 at 62.0%, a swing of 29 points on roughly 49 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Friday is the strongest day at 79.2% on time and Sunday the weakest at 67.6%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 4,074 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 56%Late-arriving aircraft
- 24%National Airspace System
- 20%Carrier
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,074 reported delay minutes here, that single category outweighs weather by 56 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,074 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 1.53% against a national 1.81%, which is ordinary. Diversions add another 1.02%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 69.9% on time across 196 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 196 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. 196 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 75.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 191 completed flights over 12 months sit behind that.
