Carrier by carrier

JetBlue against every carrier on BNA to FLL

JetBlue flew 160 of the 2,177 flights on BNA to FLL, about 7% of it. Its 70.5% on time is 3 points worse than the route as a whole, which runs 73.8%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Southwest at 74.7% to Allegiant at 64.8%. 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.

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 43 points, against half a point between the best and worst carrier.

  • 5am–8am53 flights91.5%
  • 8am–11am53 flights75.0%
  • 11am–2pm—
  • 2pm–5pm54 flights48.1%
  • 5pm–8pm—
  • 8pm–5am—

Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 91.5% of the time, against 48.1% for the afternoon window. That is 43 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 54 flights scheduled in it.

Delay causes

Why JetBlue runs late on this route

Carrier accounts for 46% of the 3,477 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    46%
  • Late-arriving aircraft
    38%
  • National Airspace System
    11%
  • Extreme weather
    5%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,477 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 3,477 reported delay minutes.

The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,612 of the 3,477 delay minutes reported here.

Cancellations run at 6.88%, against 1.89% nationally. That is about 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

15.4% 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 61.8% on time across 162 flights, 9 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 9 points of difference.

One caution: this is a thin sample. 160 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 BNA to FLL

Put together: the delay figures matter less here than the 6.88% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 149 completed flights over 12 months sit behind that.
