Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on DFW to FLL sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land close to two hours behind schedule. That rests on 311 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 596 at 72.4% on time.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on DFW 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 DFW to FLL
JetBlue flew 311 of the 3,143 flights on DFW to FLL, about 10% of it. Its 75.8% on time is 6 points better than the route as a whole, which runs 69.7%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from JetBlue at 75.8% to Frontier at 67.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 4 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.

Spirit Airlines cancels 5.0% 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 matters more here than the choice of carrier. The gap between the best and worst window is 37 points, against 4 points between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 85.1% of the time, against 47.6% for the afternoon window. That is 37 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 172 flights scheduled in it.

Share of 302 completed flights by arrival against schedule.
9 of 61 late departures made up the time and arrived on time, 15% of them. 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.
The worst days
Worst days for JetBlue on DFW to FLL
The latest arrival of the period was on 22 June 2026, 20 hours 14 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 June 2026 | 20 hours 14 minutes | Carrier |
| 9 April 2026 | 9 hours 6 minutes | Carrier |
| 27 May 2026 | 9 hours | Late-arriving aircraft |

Delay causes
Why JetBlue runs late on this route
Carrier accounts for 53% of the 8,246 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 29%Late-arriving aircraft
- 16%National Airspace System
- 2%Extreme weather
- 0%Security
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,347 of the 8,246 delay minutes reported here. The split is drawn from 8,246 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 85.1% on time here.
Cancellations run at 2.57%, against 1.89% nationally. That is about one flight in 40 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
10.3% 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 1,119 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 72.0% on time across 312 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 311 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 DFW to FLL
Put together: treat all of this as provisional. 311 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 75.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 302 completed flights over 12 months sit behind that.
