Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on FLL to DFW sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%.

These figures cover 134 flights between July 2025 and June 2026. Beyond the headline rate, 10.6% 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 DFW
JetBlue flew 134 of the 2,984 flights on FLL to DFW, about 4% of it. Its 72.0% on time is about level with the route as a whole at 72.7%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Spirit at 73.5% to Frontier at 61.2%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Spirit Airlines | 722 | 73.5% | 65 min | 2.91% | C |
| American Airlines | 1,986 | 73.2% | 100 min | 3.37% | C− |
| JetBlue Airways (this page)thin sample | 134 | 72.0% | 73 min | 0.75% | C+ |
| Frontier Airlinesthin sample | 142 | 61.2% | 70 min | 4.23% | D− |
American Airlines cancels 3.4% 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 134 flights.
There are not enough flights in each departure window to split JetBlue's FLL to DFW record by time of day without the percentages moving on noise. The headline rate of 72.0% is the reliable figure here.
Across the year
JetBlue on FLL to DFW through the year
- Jan–Mar 202630 flights—
- Apr–Jun 2026104 flights78.6%
Scale runs 70% to 85%. 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 72.0% on time across 134 flights.
Split by quarter, JetBlue on FLL to DFW logged 30 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 72.0% annual figure is the one to use.
Delay causes
Why JetBlue runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,715 reported delay minutes.
- 39%Carrier
- 36%Late-arriving aircraft
- 25%National Airspace System
- 0%Extreme weather
36% 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 2,715 reported delay minutes here, that single category outweighs weather by 36 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 2,715 reported delay minutes.
The largest share of delay minutes, 39%, 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 1,046 of the 2,715 delay minutes reported here.
Cancellations are rare at 0.75%, 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. 10.6% 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.
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. 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 77.3% on time across 133 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 134 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 DFW
Put together: treat all of this as provisional. 134 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 72.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 132 completed flights over 12 months sit behind that.
