Carrier by carrier

Frontier against every carrier on CLT to FLL

Frontier flew 224 of the 3,060 flights on CLT to FLL, about 7% of it. Its 62.4% on time is 13 points worse than the route as a whole, which runs 75.7%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from JetBlue at 79.7% to Frontier at 62.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 66% of the 5,515 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
66%
National Airspace System
20%
Carrier
12%
Extreme weather
3%

66% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,515 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 5,515 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 70.6% on time here.

Cancellations run at 4.46%, against 1.89% nationally. That is roughly one flight in twenty 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

17.8% 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 61.7% 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 CLT to FLL

Put together: the delay figures matter less here than the 4.46% 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. 213 completed flights over 12 months sit behind that.
