Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on CLE to FLL lands a B, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 514 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Frontier on CLE to FLL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The 5pm–8pm window is where this operation falls apart: 64.2% on time, against 84.6% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 210 flights scheduled in it.

The worst days
Worst days for Frontier on CLE to FLL
The latest arrival of the period was on 2 March 2026, 16 hours 42 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 March 2026 | 16 hours 42 minutes | Late-arriving aircraft |
| 16 June 2026 | 12 hours 1 minute | Extreme weather |
| 14 August 2026 | 9 hours 6 minutes | Carrier |
| 1 March 2026 | 6 hours 59 minutes | Late-arriving aircraft |
| 1 September 2025 | 4 hours 31 minutes | Late-arriving aircraft |
Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 49% of the 9,935 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 25%Carrier
- 20%National Airspace System
- 6%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,935 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 9,935 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 84.6% on time here.
Cancellations run at 2.72%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
8.4% 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 an hour and a half, which a normal layover absorbs.
The 1,062 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 70.6% on time across 514 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. 514 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 CLE to FLL
Put together: treat all of this as provisional. 514 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 77.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 498 completed flights over 12 months sit behind that.
