Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.

JetBlue on CLT to FLL lands a B−, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 160 flights. The strongest carrier on the route with a full sample, American Airlines, flew 2,069 at 77.1% on time.

The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on CLT to FLL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier

JetBlue against every carrier on CLT to FLL

JetBlue flew 160 of the 3,060 flights on CLT to FLL, about 5% of it. Its 79.7% on time is 4 points better than the route as a whole, which runs 75.7%. Ranked by on-time rate it is first 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.

Departure window

When JetBlue runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against 2 points between the best and worst carrier.

  • 5am–8am53 flights90.0%
  • 8am–11am53 flights87.8%
  • 11am–2pm—
  • 2pm–5pm54 flights63.0%
  • 5pm–8pm—
  • 8pm–5am—

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.0% of the time, against 63.0% for the afternoon window. That is 27 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 54 flights scheduled in it.

Scale runs 70% to 85%.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 79.7% on time across 160 flights.

Split by quarter, JetBlue on CLT to FLL logged 160 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 79.7% annual figure is the one to use.

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 46% of the 2,459 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    46%
  • Carrier
    31%
  • National Airspace System
    21%
  • Extreme weather
    1%

46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,459 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 2,459 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 90.0% on time here.

Cancellations run at 3.75%, against 1.89% nationally. That is about one flight in 25 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

10.5% 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 is a different operation and performs like one: it runs 58.2% on time across 162 flights, 22 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 22 points of difference.

One caution: this is a thin sample. 160 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 JetBlue on CLT to FLL

Put together: the delay figures matter less here than the 3.75% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 153 completed flights over 12 months sit behind that.
