Carrier by carrier
Frontier against every carrier on FLL to CLE
Frontier flew 514 of the 1,306 flights on FLL to CLE, about 39% of it. Its 70.6% on time is 7 points worse than the route as a whole, which runs 77.2%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from United at 89.0% to JetBlue at 60.8%.

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 514 flights.
- 5am–8am—
- 8am–11am50 flights68.0%
- 11am–2pm187 flights77.2%
- 2pm–5pm18 flights—
- 5pm–8pm77 flights67.6%
- 8pm–5am182 flights68.6%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 77.2% on time, ahead of 5pm–8pm at 67.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 187 flights scheduled in it.
Across the year
Frontier on FLL to CLE through the year
February is the weak month at 52.3% on time, against 83.3% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 68 flights.
Across the week, Wednesday is the strongest day at 87.8% on time and Sunday the weakest at 60.8%, a spread of 27 points.

Share of 497 completed flights by arrival against schedule.
48 of 162 late departures made up the time and arrived on time, 30% of them. In the other direction, 32 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 CLE.
The worst days
Worst days for Frontier on FLL to CLE
The latest arrival of the period was on 20 June 2026, 20 hours 57 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 June 2026 | 20 hours 57 minutes | Carrier |
| 16 June 2026 | 11 hours 28 minutes | Late-arriving aircraft |
| 14 August 2026 | 8 hours 34 minutes | Late-arriving aircraft |
| 1 March 2026 | 7 hours 2 minutes | National Airspace System |
| 17 November 2025 | 6 hours 11 minutes | Late-arriving aircraft |
Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 64% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Late-arriving aircraft
- 23%Carrier
- 12%National Airspace System
- 2%Extreme weather
64% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 12,929 reported delay minutes.
Cancellations run at 3.31%, against 1.89% nationally. That is about one flight in 30 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
11.7% 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 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 77.1% on time across 514 flights, 7 points above 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 FLL to CLE
Put together: the delay figures matter less here than the 3.31% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 497 completed flights over 12 months sit behind that.
