Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on FLL to CLT draws a C−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 162 flights. The strongest carrier on the route with a full sample, American Airlines, flew 2,105 at 82.3% on time.
The national on-time rate over the same period is 77.6%, so Frontier on FLL to CLT runs 12 points behind the country as a whole. Across a thousand flights that is about 120 extra late arrivals.

These figures cover 162 flights between July 2025 and June 2026. Beyond the headline rate, 12.1% 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 FLL to CLT
Frontier flew 162 of the 3,015 flights on FLL to CLT, about 5% of it. Its 65.6% on time is 13 points worse than the route as a whole, which runs 78.7%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from American at 82.3% to Frontier at 65.6%.
The choice of carrier is not cosmetic here. American Airlines arrives on time 82.3% of the time; Spirit Airlines manages 71.3%. Sample sizes sit next to every figure, because a two-point gap across 748 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| American Airlines | 2,105 | 82.3% | 98 min | 1.95% | B |
| Spirit Airlines | 748 | 71.3% | 67 min | 4.01% | C− |

Spirit Airlines cancels 4.0% 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 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am59 flights91.5%
- 11am–2pm80 flights45.5%
- 2pm–5pm4 flights—
- 5pm–8pm19 flights—
- 8pm–5am—
Scale runs 35% to 95%. 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 45.5% on time against 91.5% 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 80 flights scheduled in it.
Across the year

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 65.6% on time across 162 flights.
Split by quarter, Frontier on FLL to CLT logged 15 flights in Oct–Dec 2025, 58 flights in Jan–Mar 2026 and 89 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 65.6% annual figure is the one to use.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 4,069 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.
- 60%Late-arriving aircraft
- 25%Carrier
- 14%National Airspace System
- 0%Extreme weather
60% 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 4,069 reported delay minutes here, that single category outweighs weather by 60 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 4,069 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 91.5% on time here.
Cancellations run at 3.09%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.1% 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 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. 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 runs 66.5% on time across 162 flights, within about 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. 162 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 3.09% 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. 157 completed flights over 12 months sit behind that.
