Carrier by carrier
Frontier against every carrier on FLL to CLT
Frontier flew 224 of the 3,060 flights on FLL to CLT, about 7% of it. Its 61.7% on time is 16 points worse than the route as a whole, which runs 77.2%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from American at 82.7% to JetBlue at 58.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. American Airlines arrives on time 82.7% of the time; Spirit Airlines manages 68.5%. Sample sizes sit next to every figure, because a two-point gap across 606 flights means less than a ten-point one.

Spirit Airlines cancels 4.8% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window
When Frontier runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 46 points, against 14 points between the best and worst carrier.
- 5am–8am—
- 8am–11am63 flights92.1%
- 11am–2pm86 flights45.8%
- 2pm–5pm4 flights—
- 5pm–8pm71 flights49.2%
- 8pm–5am—
Scale runs 35% to 100%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 45.8% on time against 92.1% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 86 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 61.7% on time across 224 flights.
Frontier on FLL to CLT did not run the same all year. Its best quarter was Apr–Jun 2026 at 72.7% on time and its weakest Jul–Sep 2026 at 50.0%, a swing of 23 points on roughly 75 flights a quarter.

Share of 209 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 74 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 14 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 CLT.
The worst days
Worst days for Frontier on FLL to CLT
The latest arrival of the period was on 12 March 2026, 9 hours 40 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 March 2026 | 9 hours 40 minutes | Carrier |
| 2 January 2026 | 5 hours 40 minutes | Late-arriving aircraft |
| 29 January 2026 | 4 hours 44 minutes | Late-arriving aircraft |
| 22 August 2026 | 4 hours 40 minutes | Late-arriving aircraft |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 61% of the 6,219 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 22%Carrier
- 16%National Airspace System
- 1%Extreme weather
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,219 reported delay minutes here, that single category outweighs weather by 61 to one. The split is drawn from 6,219 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.1% on time here.
Cancellations run at 6.70%, against 1.89% nationally. That is about one flight in fifteen 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
15.3% 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 632 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 runs 62.4% on time across 224 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 224 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 CLT
Put together: the delay figures matter less here than the 6.70% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 209 completed flights over 12 months sit behind that.
