Carrier by carrier
JetBlue against every carrier on FLL to BNA
JetBlue flew 162 of the 2,193 flights on FLL to BNA, about 7% of it. Its 61.8% on time is 6 points worse than the route as a whole, which runs 68.0%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Spirit at 69.1% to Allegiant at 61.5%. 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.

Spirit Airlines cancels 4.6% 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 13 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm54 flights64.8%
- 2pm–5pm—
- 5pm–8pm54 flights66.7%
- 8pm–5am54 flights54.0%
Scale runs 45% to 70%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 54.0% on time, against 66.7% for the 5pm–8pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 54 flights scheduled in it.

Split by quarter, JetBlue on FLL to BNA logged 162 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 61.8% annual figure is the one to use.

Share of 152 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 55 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 8 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 BNA.
The worst days
Worst days for JetBlue on FLL to BNA
The latest arrival of the period was on 27 August 2026, 4 hours 40 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Five of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 August 2026 | 4 hours 40 minutes | Late-arriving aircraft |
| 27 August 2026 | 4 hours 2 minutes | Carrier |
| 3 August 2026 | 3 hours 54 minutes | Late-arriving aircraft |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 47% of the 4,038 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 30%Carrier
- 20%National Airspace System
- 3%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,038 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 4,038 reported delay minutes.
Cancellations run at 6.17%, against 1.89% nationally. That is roughly one flight in fifteen 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
15.1% 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 793 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 70.5% on time across 160 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 162 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 BNA
Put together: the delay figures matter less here than the 6.17% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 152 completed flights over 12 months sit behind that.
