These figures cover 303 flights between September 2025 and August 2026. The median arrival is 9 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.

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 303 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 82.1% is the reliable figure here.

Share of 296 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 36 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 21 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 FLL.

Delay causes

Why JetBlue runs late on this route

Carrier accounts for 49% of the 4,344 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System

The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,129 of the 4,344 delay minutes reported here. The split is drawn from 4,344 reported delay minutes.

Cancellations sit at 2.31% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

7.8% of arrivals land an hour or more late, close to the national 8.3%, so 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.

The return leg is a different operation and performs like one: it runs 57.7% on time across 304 flights, 24 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 24 points of difference.

One caution: this is a thin sample. 303 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. 303 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 82.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 296 completed flights over 12 months sit behind that.
