JetBlue against every carrier on FLL to DFW

JetBlue flew 312 of the 3,149 flights on FLL to DFW, about 10% of it. Its 72.0% on time is about level with the route as a whole at 72.1%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from American at 74.0% to Frontier at 57.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 3 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.

Delay causes

Why JetBlue runs late on this route

Carrier accounts for 43% of the 6,122 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
43%
Late-arriving aircraft
38%
National Airspace System
17%
Extreme weather
3%

38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,122 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 6,122 reported delay minutes.

The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,617 of the 6,122 delay minutes reported here.

Cancellations sit at 2.24% against a national 1.89%, which is ordinary. Diversions add another 0.32%.

Connections and stage length

What a delay here costs

11.8% 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 75.8% on time across 311 flights, 4 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 4 points of difference.

One caution: this is a thin sample. 312 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. 312 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. 304 completed flights over 12 months sit behind that.
