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

JetBlue on PIT to FLL lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 241 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 395 at 79.3% on time.

Set against the rest of the country, JetBlue's PIT to FLL record is 5 points better than the US average of 77.6%. That gap is worth roughly 47 fewer late arrivals for every thousand flights.

Every carrier on PIT to FLL, 1,105 flights

These figures cover 241 flights between July 2025 and June 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

JetBlue against every carrier on PIT to FLL

JetBlue flew 241 of the 1,105 flights on PIT to FLL, about 22% of it. Its 82.3% on time is 2 points better than the route as a whole, which runs 79.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from JetBlue at 82.3% to Spirit at 79.1%.

The two carriers here are closely matched: half a point 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.

On-time performance by carrier on PIT to FLL

Spirit Airlines cancels 4.9% 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 JetBlue 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 241 flights.

There are not enough flights in each departure window to split JetBlue's PIT to FLL record by time of day without the percentages moving on noise. The headline rate of 82.3% is the reliable figure here.

Across the year

JetBlue on PIT to FLL through the year

Oct–Dec 202560 flights83.3%
Jan–Mar 202690 flights73.3%
Apr–Jun 202691 flights90.1%

Scale runs 65% to 95%. 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 82.3% on time across 241 flights.

JetBlue on PIT to FLL did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.1% on time and its weakest Jan–Mar 2026 at 73.3%, a swing of 17 points on roughly 80 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Friday is the strongest day at 100.0% on time and Sunday the weakest at 67.6%. 32 points is a smaller lever than departure hour, but it is free.

Delay causes

Why JetBlue runs late on this route

One category carries most of the weight here. Carrier accounts for 46% of the 3,821 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.

The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,744 of the 3,821 delay minutes reported here. The split is drawn from 3,821 reported delay minutes.

Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

The 994 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 is a different operation and performs like one: it runs 57.6% on time across 242 flights, 25 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 25 points of difference.

One caution: this is a thin sample. 241 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 PIT to FLL

Put together: treat all of this as provisional. 241 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 82.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 237 completed flights over 12 months sit behind that.
