These figures cover 232 flights between July 2025 and June 2026. Beyond the headline rate, 18.3% 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

JetBlue against every carrier on FLL to TPA

JetBlue flew 232 of the 1,422 flights on FLL to TPA, about 16% of it. Its 66.1% on time is 8 points worse than the route as a whole, which runs 73.8%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Southwest at 86.5% to JetBlue at 66.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 232 flights.

The overnight block holds up unusually well at 65.4% on time across 209 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 209 flights scheduled in it.

Across the year

JetBlue on FLL to TPA through the year

Oct–Dec 202528 flights—
Jan–Mar 2026100 flights67.3%
Apr–Jun 2026104 flights66.3%

Scale runs 60% to 75%. 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 66.1% on time across 232 flights.

Split by quarter, JetBlue on FLL to TPA logged 28 flights in Oct–Dec 2025, 100 flights in Jan–Mar 2026 and 104 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 66.1% annual figure is the one to use.

Across the week, Wednesday is the strongest day at 86.7% on time and Sunday the weakest at 44.1%. 43 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. Late-arriving aircraft accounts for 52% of the 5,982 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.

52% 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 5,982 reported delay minutes here, that single category outweighs weather by 7 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 5,982 reported delay minutes.

Cancellations are rare at 0.86%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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. 18.3% 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.

At 197 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8pm–5am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 89.0% on time across 231 flights, 23 points above 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 23 points of difference.

One caution: this is a thin sample. 232 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 FLL to TPA

Put together: treat all of this as provisional. 232 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 66.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 230 completed flights over 12 months sit behind that.
